Analysis of the main approaches to modeling management processes for special-purpose organizational and technical systems

Objective. Currently, the task of increasing the spectral solvability of a video stream using modern frame filtering methods is urgent. Various methods of frame filtering are considered and analyzed in the work, and their detailed comparative analysis is carried out. The obtained data contribute to the further development of various materials to increase the spectral resolution of the video stream. Method. A large number of different approaches have been developed in the scientific literature to increase the spectral resolution of a video stream using modern frame filtering methods, and the most basic ones are analyzed in this paper: linear spatial filtering; nonlinear spatial filtering; spatial frequency filtering; filtering using Fourier analysis; filtering based on wavelet analysis. Result. A preliminary systematization of the characteristics of the methods under consideration has been carried out in order to develop new algorithms and implement them to improve image quality, increase detail and clarity of the video stream; various frame filtering methods have been analyzed, contributing to an increase in the spectral resolution of the video stream, and their impact on the quality of video content has been considered; during the analysis, it was found that in order to increase the spectral solvability of the video stream, it is necessary to use a combined filter. The above facts will allow us to further develop methodological recommendations for increasing the spectral solvability of the video stream. Conclusion. The considered approaches to increasing the spectral resolution of a video stream using modern frame filtering methods are preferable when increasing the spectral resolution of images, since they use all the positive aspects of linear, nonlinear and spatial frequency filtering.

Quality of Video Content Related to Deep Inferior Epigastric Perforator Flap Breast Reconstruction: Social Media Platforms Versus Large Language Models.

The deep inferior epigastric perforator (DIEP) flap is currently one of the main options in breast reconstruction. The information about this surgery is critical for the patient, in order to choose the breast reconstruction method. Our study aims to analyze and compare the quality and accuracy of the information related to the DIEP flap reconstruction method provided by social media platforms (SMPs) and the new large language models (LLMs). A total of 50 videos in English and Spanish were selected from the main SMPs (YouTube, Instagram, and Facebook) using the keywords "DIEP flap" and "colgajo DIEP." The duration, number of likes, dislikes, number of visits, upload date, author, and the video category (institutional video, media, patient experience, academic, and surgery) were analyzed. 3 specific questions were asked to 2 new LLMs (ChatGPT and Google Bard). The quality of information in SMPs and LLMs was analyzed and compared by 2 independent board-certified plastic surgeons using the Journal of American Medical Association and DISCERN scales. LLMs showed a statistically significant higher quality of information when compared with SMPs based on the DISCERN scores. The average DISCERN scores for answers given by ChatGPT and Google Bard were 54 ± 6.841 and 61.17 ± 6.306, respectively (good quality). In SMPs, the average scores were 2.31 ± 0.67 (insufficient quality) and 32.87 ± 9.62 (low quality) for the Journal of American Medical Association and DISCERN scales respectively. Thirty-eight percent of the videos in SMPs were performed by nonmedical authors. The quality of information for breast reconstruction using DIEP flaps from LLMs was considered good and significantly better than in SMPs. The information found in SMPs was insufficient and of low quality. Academic plastic surgeons have an opportunity to provide quality content on this type of reconstruction in LLM and SMPs.

Evaluating the Information Quality of YouTube Videos on Manual Medicine/Therapy

ObjectivesThis study evaluates the educational quality and reliability of manual medicine/therapy-related YouTube videos to determine their suitability for information seekers and their potential use in manual therapy education. MethodsA cross-sectional analysis of 113 YouTube videos related to manual medicine/therapy was conducted. Video characteristics, including likes, dislikes, view count, duration, and speaker profile, were assessed. Popularity, educational quality, and reliability were evaluated using the Video Power Index (VPI), Global Quality Scale (GQS), Journal of the American Medical Association (JAMA) criteria, and modified DISCERN tool. ResultsNo significant differences were found among speaker groups (physicians, physiotherapists, osteopaths & chiropractors) in assessment parameters. Videos on “Manipulation” and “Mobilization/Stretching/Examination” received more likes and views than “General Information” videos. Video duration positively correlated with JAMA, GQS, and mDISCERN scores, indicating higher educational quality in longer videos. However, overall educational quality and reliability were moderate to weak. ConclusionsThe study underscores the need for content creators to enhance the educational quality of manual medicine/therapy videos. Practical application-oriented content is popular, and quality video resources can serve as a valuable complement to hands-on instruction in manual therapy education. Implications for practice1.This study provides a comprehensive evaluation of YouTube videos on manual medicine/therapy, highlighting no significant superiority in educational quality and reliability among videos from different professional speakers.2.This research fills a gap by offering a broad perspective on the educational value of these videos, which has not been explored in such depth previously.3.Despite moderate to weak overall educational quality and reliability, videos focusing on practical applications such as manipulation and mobilization/stretching/examination are more popular and frequently viewed. This suggests that such content might serve as an effective supplement to manual therapy training and also proves valuable in demonstrating to patients the procedures involved in manual therapy, enhancing their understanding and engagement with treatment protocols.4.Enhancing video content quality could significantly benefit manual therapy education by providing high-quality, reliable resources that complement traditional educational methods, especially in demonstrating practical techniques.

How Useful Is TikTok for Patients Searching for Carpal Tunnel Syndrome-Related Treatment Exercises?

Since orthopedic surgery has been slower to acknowledge the rise of social media for distributing medical information, this study aims to evaluate TikTok videos' quality and educational value in relation to carpal tunnel syndrome treatment exercises. TikTok was searched using the hashtags "#carpaltunnelexercises", "#carpaltunnelremedies", "#carpaltunnelrehab", and "#physicaltherapyforcarpaltunnel". The engagement indicators were documented and the video content quality was assessed using the DISCERN, CTEES, JAMA, and GQS grading scales. There were 101 videos included, which accumulated 20,985,730 views. The videos received 1,460,953 likes, 15,723 comments, 243,245 favorites, and 159,923 shares. Healthcare professionals were responsible for 72% of the video uploads, whereas general users contributed 28%. More healthcare professionals' videos were graded as "poor" (79%) compared to general users (21%). General users received slightly more video grades of "very poor" (52%) than healthcare professionals (48%). For the DISCERN grading, the videos by healthcare professionals were significantly better than those by general users in terms of reliability, achieving aims, and relevancy. They were also superior in the overall composition of the health information derived from the total DISCERN score. However, no significant differences were found between the two groups when using the CTEES, JAMA, and GQS grading scales. Overall, despite the emergence of TikTok as a medical information tool, the quality and educational value of the carpal tunnel syndrome exercise videos were poor.

YouTube as a source of education in perioperative anesthesia for patients and trainees: a systematic review.

Online video sharing platforms like YouTube (Google LLC, San Bruno, CA, USA) have become a substantial source of health information. We sought to conduct a systematic review of studies assessing the overall quality of perioperative anesthesia videos on YouTube. We searched Embase, MEDLINE, and Ovid for articles published from database inception to 1 May 2023. We included primary studies evaluating YouTube videos as a source of information regarding perioperative anesthesia. We excluded studies not published in English and studies assessing acute or chronic pain. Studies were screened and data were extracted in duplicate by two reviewers. We appraised the quality of studies according to the social media framework published in the literature. We used descriptive statistics to report the results using mean, standard deviation, range, and n/total N (%). Among 8,908 citations, we identified 14 studies that examined 796 videos with 59.7hr of content and 47.5 million views. Among the 14 studies that evaluated the video content quality, 17 different quality assessment tools were used, only three of which were externally validated (Global Quality Score, modified DISCERN score, and JAMA score). Per global assessment rating of video quality, 11/13 (85%) studies concluded the overall video quality as poor. Overall, the educational content quality of YouTube videos evaluated in the literature accessible as an educational resource regarding perioperative anesthesia was poor. While these videos are in demand, their impact on patient and trainee education remains unclear. A standardized methodology for evaluating online videos is merited to improve future reporting. A peer-reviewed approach to online open-access videos is needed to support patient and trainee education in anesthesia. Open Science Framework ( https://osf.io/ajse9 ); first posted, 1 May 2023.

YouTube™ Videos as a Source of Information on Necrotizing Gingivitis: A Content-Quality Analysis.

Background This study aimsto evaluate the quality, reliability, and content of the information provided in YouTube™ videos on necrotizing gingivitis (NG), demonstrate the effectiveness of the videos for patients, and help dentists use this platform as a resource to properly guide their patients. Methodology This cross-sectional study was conducted by two experienced periodontologists. They began the study by searching for YouTube™ videos using the keywords "necrotizing gingivitis" and "trench mouth."Descriptive parameters such as the source of upload, country of origin, duration, upload date, number of likes, dislikes, views, and comments were evaluated. After this initial evaluation, the viewing rate and interaction index were calculated. Videos were categorized into high content (HC) and low content (LC) based on a 7-point scale. The quality of video content was assessed using the Global Quality Scale (GQS) and the Video Information and Quality Index (VIQI). The data were analyzed using various statistical tests, with a significance level set at p<0.05. Results Initially, 148 videos were screened, and 50 videos on NG that met the inclusion criteria were included in the study. Out of the 50 videos, 28 (56%) were uploaded by healthcare professionals. Overall, 68% of videos (n=34) were classified as HCand 32% (n=16) as LC. The most common topic was clinical symptoms and signs of NG, with 86% (n=43), while NG prevention was the least common topic, with 26% (n=13). Statistically significant differences were found between video duration, time since upload, and VIQI scores according to TCS scores (p<0.05). Video duration and VIQI scores were higher for HC videos compared to LC videos. The time since upload for LC videos was higher than for HC videos. Positive correlations were observed between TCS scores, video duration, and VIQI, as well as between GQS scores, video duration, viewing rate, and VIQI. Conclusions The majority of NG videos on YouTube™ are useful and comprehensive, but their number is insufficient. Poor-quality and inadequate videos may mislead practitioners and patients. However, this also presents an opportunity for healthcare professionals to leverage YouTube™ as an educational tool. Periodontologists should upload more comprehensive videos and play a more active role in providing high-quality information.

Freely available, online videos to support neurological physiotherapists and students in task-specific training skill acquisition: a scoping review

BackgroundVideos to support learning of clinical skills are effective; however, little is known about the scope and educational quality of the content of freely available online videos demonstrating task-specific training (TST). This review aimed to determine the extent, characteristics of freely available online videos, and whether the content is suitable to guide skill acquisition of task-specific training for neurological physiotherapists and students.MethodsA scoping review was conducted. Google video and YouTube were searched in December 2022. Videos that met our eligibility criteria and were explicitly designed for (TST) skill acquisition were included in the report.ResultsTen videos met the inclusion criteria and were difficult to find amongst the range of videos available. Most were presented by physiotherapists or occupational therapists, originated from the USA, featured stroke as the condition of the person being treated, and involved a range of interventions (upper limb, constraint induced movement therapy, balance, bicycling). Most videos were created by universities or private practices and only two used people with a neurological condition as the participant. When the content of videos and their presentation (instruction and/or demonstration), was assessed against each key component of TST (practice structure, specificity, repetition, modification, progression, feedback), five of the videos were rated very suitable and five moderately suitable to guide skill acquisition. Most videos failed to demonstrate and provide instruction on each key component of TST and were missing at least one component, with feedback most frequently omitted.ConclusionsThere are many freely available online videos which could be described as demonstrating TST; very few are suitable to guide skill acquisition. The development of a standardised and validated assessment tool, that is easy to use and assesses the content of TST videos is required to support learners to critically evaluate the educational quality of video content. Guidelines based on sound teaching theory and practice are required to assist creators of online videos to provide suitable resources that meet the learning needs of neurological physiotherapists and students.

Assessment of the Quality of Sinus Elevation with Lateral Window Approach Procedure Videos on YouTube: A Content-quality Analysis.

Although the lateral window approach allows for greater graft material delivery and bone formation, it is more challenging and invasive, prompting keen interest among dentists to master this method. YouTube is increasingly used for medical training; however, concerns regarding the quality of instructional videos exist. This study proposes new criteria for evaluating YouTube videos on maxillary sinus elevation with the aim of establishing standards for assessing instructional content in the field. We sourced 100 maxillary sinus elevation videos from YouTube and, following exclusion criteria, analyzed 65 remaining videos. The video characteristics, content quality, and newly developed criteria were evaluated. Statistical analyses, employing ordinal logistic regression, identified the factors influencing the quality of instructional videos and evaluated the significance of our new criteria. Although video interaction and view rate exhibited positive relations to content quality, they were not significant ( P =0.818 and 0.826, respectively). Notably, videos of fair and poor quality showed a significant negative relation ( P <0.001). Audio commentary, written commentary, and descriptions of preoperative data displayed positive but statistically insignificant relationships ( P =0.088, 0.228, and 0.612, respectively). The comparison of video evaluation results based on the developed criteria with content quality scores revealed significant negative relationships for good, fair, and poor videos ( P <0.001, Exp(B)=-4.306, -7.853, -10.722, respectively). Among the various video characteristics, only image quality showed a significant relationship with content quality. Importantly, our newly developed criteria demonstrated a significant relationship with video content quality, providing valuable insights for assessing instructional videos on maxillary sinus elevation and laying the foundation for robust standards.

Analysis and Improvement Strategies of Gansu Youth League Official Short Video Content from the Perspective of Recognition

How to enhance the recognition of new media Official Short Videos among users? This paper selects the Douyin account of the Youth League of Gansu Province for analysis. Based on the literature on evaluating the effectiveness of communication of short videos, this article has developed a model for measuring video identity, and provided content analysis for the 9% of Gansu Youth League members with the highest degree of identity using this model. In the research, this article found that video materials tend to be official and original videos, and tends to focus on comprehensive organization, local content, and positive emotions. High quality video content in the form of video, plus the popular sound effect of only music, and videos with tags to participate in topics or Douyin challenges that last between 1 and 15 seconds, have the greatest chance of gaining user recognition. At the same time, official video sources, original videos, and videos from local sources have the highest correlation with recognition. Therefore, this article believes that in order to gain recognition for future Official Short Videos, more efforts should be made in these three aspects.

Evaluation of the reliability and accuracy of YouTube™ and TikTok™ contents about storage media for avulsed teeth: A cross-sectional study.

The preservation of avulsed teeth is critical in dental trauma management, necessitating effective storage media to ensure viable tooth reimplantation. The urgent need for accurate information has led both professional and non-professional individuals to increasingly seek guidance from video-sharing platforms such as YouTube™ and TikTok™. These platforms have become key resources for advice on such dental emergencies, but the reliability and accuracy of this information have not yet been systematically evaluated. This study aimed to assess the quality, accuracy, and reliability YouTube™ and TikTok™ of videos regarding storage solutions for avulsion injuries. A search was conducted on YouTube™ and TikTok™ on February 4th, 2023, using terms related to traumatic dental injuries, and 53 videos were included. Video demographics such as platform, duration, type, upload date, likes, and comments were recorded. Video content quality, reliability, and accuracy were measured using the Global Quality Scale (GQS), Journal of the American Medical Association (JAMA) benchmarks, and Video Information and Quality Index (VIQI). Research data were analyzed using SPSS IBM 24.0 at a 95% confidence interval. In total, 53 videos were examined. The average scores were JAMA: 1.70/4.00, modified DISCERN: 54.3/80.00, GQS: 3.88/5.00, and VIQI: 13.8/20.00. According to the modified DISCERN index, there were no "very poor" or "poor" quality videos, 49.05% were "moderate," 22.6% were "good," and 28.3% were "very good." No difference was found between YouTube™ and TikTok™ videos in terms of the modified DISCERN index, JAMA scores, GQS, and VIQI scoring (p > .05). Traumatic dental injuries are a common problem among children, and evaluating the reliability of available contents is becoming crucial for appropriate intervention. The study reveals that despite being sourced mainly from dental professionals, the overall quality of videos on avulsed tooth management was mediocre, underscoring the risks associated with misleading or incomplete information in such critical situations.

TikTok content as a source of health education regarding epicondylitis: a content analysis

PurposeThis study aimed to assess the validity and informational value of TikTok content about epicondylitis. The hypothesis tested herein was that TikTok video content would not provide adequate and valid information.MethodsThe term “epicondylitis” was used as a keyword to comprehensively search for TikTok videos, and the first 100 videos that were retrieved were subsequently included for analysis. The duration, number of likes, number of shares and number of views were recorded for each video. Furthermore, the videos were categorized on the basis of their source (medical doctor, physiotherapist, or private user), type of information (physical therapy, anatomy, clinical examination, etiopathogenesis, patient experience, treatment, or other), video content (rehabilitation, education, or patient experience/testimony), and the presence of music or voice. Assessments of video content quality and reliability were conducted using the DISCERN tool, the Journal of the American Medical Association (JAMA) benchmark criteria, and the Global Quality Score (GQS).ResultsA total of 100 videos were included in the analysis: 78 (78.0%) were published by physiotherapists, 18 were published by medical doctors (18.0%), and 4 were published by private users (4.0%). Most of the information pertained to physical therapy (75; 75.0%) and most of the content was about rehabilitation (75; 75.0%). The mean length of the videos was 42.51 ± 24.75 seconds; the mean number of views was 193,207.78 ± 1,300,853.86; and the mean number of comments, likes, and shares were 22.43 ± 62.54, 1578.52 ± 8333.11, and 149.87 ± 577.73, respectively. The mean DISCERN score, JAMA score, and GQS were 18.12 ± 5.73, 0.80 ± 0.53, and 1.30 ± 0.52, respectively. Videos posted by medical doctors/private users had higher scores (p < 0.05) than videos posted by physiotherapists. Videos that focused on education or patient experience had higher scores (p < 0.05) than videos based on rehabilitation.ConclusionsTikTok can be an unreliable source of information regarding epicondylitis treatment. It is common to find nonphysicians who share medical advice on the platform, with medical treatments demonstrating the weakest level of supporting evidence. Elbow surgeons should advise their patients that treatment recommendations from TikTok may not align with established guidelines.Level of Evidence: Level IV—Cross-sectional study.

Information videos posted on Instagram by orthopaedics and sports traumatology surgeons mostly explain surgical technique, and the least mentioned topics are injury prevention and complications.

Social media has become the new information acquisition platform for all content producers. In the current literature, there are no studies examining the content quality and the strengths and weaknesses of videos on Instagram that explain anterior cruciate ligament (ACL) injuries, which is the most discussed topic of sports surgery. The aim of this study was to evaluate the quality, strengths and weaknesses of information pertaining to ACL surgery that is disseminated on Instagram. An Instagram search was conducted from 30 May 2023 to 30 January 2024. The search encompassed six languages (English, Spanish, German, French, Italian and Turkish) and was performed by six different observers. The investigation focused on eight subheadings derived from current literature on the ACL. These subheadings were addressed in Instagram videos, covering ACL biology or biomechanics, injury mechanism, injury prevention, injury evaluation, surgical technique, injury or surgery complications, injury rehabilitation process and return to sport or work. The content was assessed of 127 videos from 127 Instagram accounts, spanning six different languages. Across the review of eight subheadings, the average number covered for the entire group was 3 (range, 0-8). Further analysis revealed that surgical technique was the most frequently mentioned subheading for the whole group (68.5%), followed by injury evaluation (54.3%). Prevention (10.2%) and complications (19.6%) were the least mentioned subheadings. The number of followers showed a correlation with video content quality. Although the video quality scores were found to be moderate, the content often focused on surgery and evaluation subheadings. The prevalence of incomplete information underscores the importance of developing strategies to ensure more comprehensive and accurate dissemination of medical knowledge. Level V.

Assessing Laryngectomy Patient Education on YouTube: Investigating Quality and Reliability.

This study aimed to characterize the quality of laryngectomy-related patient education on YouTube and understand factors impacting video content quality. Cross-sectional cohort analysis. Laryngectomy-related videos on YouTube. YouTube was anonymously queried for various laryngectomy procedure search terms. Video quality was evaluated using the validated DISCERN instrument which assesses treatment-related information quality. Descriptive statistics were used to characterize our cohort. Univariate and multivariable linear regression were used to assess factors associated with increased DISCERN score. Significance was set at P < .05. Our 78-video cohort exhibited moderate levels of engagement, averaging 13,028.40 views (SD = 24,246.93), 69.79 likes (SD = 163.75), and 5.27 comments (SD = 18.81). Videos were most frequently uploaded to accounts belonging to physicians (43.59%) or health care groups (41.03%) and showcased operations (52.56%) or physician-led education (20.51%). Otolaryngologists were featured in most videos (85.90%), and most videos originated outside the United States (67.95%). Laryngectomy videos demonstrated poor reliability (mean = 2.35, SD = 0.77), quality of treatment information (mean = 1.92, SD = 0.86), and overall video quality (mean = 1.97, SD = 1.12). In multivariable linear regression, operative videos were associated with lower video quality relative to nonoperative videos (β = -1.63, 95% confidence interval [CI] = [-2.03 to -1.24], P < .001); the opposite was true for videos from accounts with higher subscriber counts (β = 0.02, 95% CI = [0.01-0.03], P = .005). The quality and quantity of YouTube's laryngectomy educational content is limited. There is an acute need to increase the quantity and quality of online laryngectomy-related content to better support patients and caregivers as they cope with their diagnosis, prepare for, and recover from surgery.

CONTENT ANALYSIS OF YOUTUBE VIDEOS RELATED TO MAXILLARY CENTRAL INCISOR TOOTH MANIPULATION

BACKGROUND: Today video sharing platforms on Internet like Youtube has become an important source of information in many areas like health. purpose of this investigation is to evaluate the suitability, usefulness, and quality of Youtube video contents related to 'Maxillary Central Incisive Tooth Manipulation’ used by dentistry students for first-year preclinical education. &#x0D; MATERIAL and METHODS: A scoring system consisting of 10 parameters was used to asses the video content quality. The viewership, likes, comments, reliability of information, global quality scores(GQS), and video duration were recorded for evaluation with parameters by two dentists according to the uploader (dentist, dentistry student, dental technician) and the information content (high, medium, poor quality). Group comparisons were analysed using the Kruskal Wallis H and post-hoc Tamhane’s T2 test. &#x0D; RESULTS: 20 relevant videos were classified as 55% high(GQS 4.7±0.6), 35% medium(GQS 3.3±1.6), and 10% considered poor quality(GQS 1.0±0). Evaluated according to their quality, no significant difference was found between the parameters except GQS(p=0.013). The videos are as follows, in order of their sources: dentists(n=6,30%), dentistry students(n=11,55%) and dental technicians(n=3,15%). &#x0D; CONCLUSION: The fact that there was no difference in the viewing and popularity of useful and misleading videos revealed that the high quality video could not be chosen by the video viewers. In this study, it was concluded that dentistry students should pay particular attention to the video provider while providing video access to support their preclinical education. Health academics and health institutions need to increase studies on 'pre-clinical practice courses' and try to raise awareness by uploading more useful and systematic videos to the internet/YouTube.

Reliability and Accuracy of YouTube Peri-Implantitis Videos as an Educational Source for Patients in Population-Based Prevention Strategies.

Considering the need to improve patient knowledge, awareness, and compliance for peri-implantitis prevention, and patients' demand for better, quick, and convenient access to medical information, the present study primarily assessed the reliability and accuracy of YouTube videos on peri-implantitis and secondarily evaluated their educational value for the patients, and the related suitability, as part of population-based preventive strategies, to deliver valid information, potentially capable of improving patient knowledge and educational skills. This study's protocol was developed in advance, and computer history and cookies were cleared to avoid limitations based on preferred user histories. The search term "peri-implantitis" was defined using the Google Trends website, and videos were searched on YouTube on 5 December 2022. Video inclusion and data collection were conducted by independent pre-calibrated investigators. Descriptive statistics were performed on the videos' characteristics, source, category, target audience, popularity, source reliability, video information and quality (VIQI), content, and educational value. Pearson's correlation between educational value and all parameters was calculated. Videos with very low/low and medium/good/excellent educational value were compared using the Mann-Whitney U test. A total of 44 videos with medium values for popularity, VIQI, content, and educational value were analyzed. Most videos covered peri-implantitis treatment rather than etiology and prevention, about half were uploaded by dentists/specialists, and only 10% specifically targeted patients. Only 2% of YouTube videos about peri-implantitis had excellent educational value, and 5% had good educational value. Video educational value was correlated with VIQI and content beyond video length and source reliability. When comparing the very low/low and medium/good/excellent educational value YouTube videos on peri-implantitis, a significant difference was found in the Video Information and Quality Index, VIQI, and video content.

Arabic Sentiment Analysis of YouTube Comments: NLP-Based Machine Learning Approaches for Content Evaluation

YouTube is a popular video-sharing platform that offers a diverse range of content. Assessing the quality of a video without watching it poses a significant challenge, especially considering the recent removal of the dislike count feature on YouTube. Although comments have the potential to provide insights into video content quality, navigating through the comments section can be time-consuming and overwhelming work for both content creators and viewers. This paper proposes an NLP-based model to classify Arabic comments as positive or negative. It was trained on a novel dataset of 4212 labeled comments, with a Kappa score of 0.818. The model uses six classifiers: SVM, Naïve Bayes, Logistic Regression, KNN, Decision Tree, and Random Forest. It achieved 94.62% accuracy and an MCC score of 91.46% with NB. Precision, Recall, and F1-measure for NB were 94.64%, 94.64%, and 94.62%, respectively. The Decision Tree had a suboptimal performance with 84.10% accuracy and an MCC score of 69.64% without TF-IDF. This study provides valuable insights for content creators to improve their content and audience engagement by analyzing viewers’ sentiments toward the videos. Furthermore, it bridges a literature gap by offering a comprehensive approach to Arabic sentiment analysis, which is currently limited in the field.

Content Quality of Web-Based Short-Form Videos for Fire and Burn Prevention in China: Content Analysis.

Web-based short-form videos are increasingly popular for disseminating fire and burn prevention information, but their content quality is unknown. We aimed to systematically assess the characteristics, content quality, and public impact of web-based short-form videos offering primary and secondary (first aid) prevention recommendations for fires and burns in China between 2018 and 2021. We retrieved short-form videos offering both primary and secondary (first aid) information to prevent fire and burn injuries published on the 3 most popular web-based short-form video platforms in China: TikTok, Kwai, and Bilibili. To assess video content quality, we calculated the proportion of short-form videos that included information on each of the 15 recommendations for burn prevention education from the World Health Organization (WHO; P1) and that correctly disseminated each recommendation (P2). High P1 and P2 indicated better content quality. To assess their public impact, we calculated the median (IQR) of 3 indicators: the number of comments, likes, and saves as a favorite by viewers. Chi-square test, trend chi-square test, and Kruskal-Wallis H test examined differences in indicators across the 3 platforms, years, content, and time duration of videos and between videos disseminating correct versus incorrect information. Overall, 1459 eligible short-form videos were included. The number of short-form videos increased by 16 times between 2018 and 2021. Of them, 93.97% (n=1371) were about secondary prevention (first aid) and 86.02% (n=1255) lasted <2 minutes. The proportion of short-form videos including each of the 15 WHO recommendations ranged from 0% to 77.86% (n=1136). Recommendations 8, 13, and 11 had the highest proportions (n=1136, 77.86%; n=827, 56.68%; and n=801, 54.9%, respectively), whereas recommendations 3 and 5 were never mentioned. Among the short-form videos that included the WHO recommendations, recommendations 1, 2, 4, 6, 9, and 12 were always disseminated correctly, but the other 9 recommendations were correctly disseminated in 59.11% (120/203) to 98.68% (1121/1136) of videos. The proportion of short-form videos including and correctly disseminating the WHO recommendations varied across platforms and years. The public impact of short videos varied greatly across videos, with a median (IQR) of 5 (0-34) comments, 62 (7-841) likes, and 4 (0-27) saves as a favorite. Short-form videos disseminating correct recommendations had larger public impact than those disseminating either partially correct or incorrect knowledge (median 5 vs 4 comments, 68 vs 51 likes, and 5 vs 3 saves as a favorite, respectively; all P<.05). Despite the rapid increase in the number of web-based short-form videos about fire and burn prevention available in China, their content quality and public impact were generally low. Systematic efforts are recommended to improve the content quality and public impact of short-form videos on injury prevention topics such as fire and burn prevention.

Does the content quality of YouTube videos about aligners differ from the perspectives of dentists and orthodontists?

Objectives: This study aimed to content quality analysis of YouTube videos about aligners in orthodontics by a dentist and by an orthodontist. Material and Methods: Considering the Google Trends analysis, the “aligner,” as the most searched keyword about aligners in orthodontics, was chosen for YouTube searching. A total of 39 included videos were watched for one time by a dentist and orthodontist. Time since upload, video duration, number of views, number of likes, number of dislikes, and number of comments were recorded. Moreover, the interaction index and viewing rate were calculated and the reliability score, video content quality (VCQ), video interaction and quality index (VIQI), and global quality scales (GQS) were recorded by both viewers. Interobserver agreement levels were interpreted with the Concordance Correlation Coefficient (CCC) and data were evaluated at P &lt; 0.05 as the statistically significant level. Results: The results showed that most of the included videos (48.71%) were uploaded by dental companies. However, the averages of VCQ in terms of uploaders were similar for both viewers. The agreement level in all videos between orthodontist and dentist was “good” level at VIQI (CCC = 0.965) and GQS (CCC = 0.943), whereas it was “very poor” level on VCQ (CCC = 0.653). Conclusion: The findings revealed that YouTube video contents about aligners provide moderate information and VCQ, independently from viewers, is similar among uploaders. The agreement levels between dentist and orthodontist on the evaluation of audiovisual quality of the videos were good, whereas this level was poor on the evaluation of information quality of videos.
