THE ROLE OF THE CAPITAL CITY MAGAZINES IN PRESENTING THE KALMYK ETHNOS TO THE RUSSIAN AUDIENCE IN THE FIRST DECADES OF THE XIX CENTURY

The purpose of the study was to specify the representation of the Kalmyk ethnic group in St. Petersburg and Moscow magazines in the fi rst decades of the XIX century. The study of publications in the journals Vestnik Evropy, Syn Otechestva, Otechestvennye Zapiski, Sibirskiy Vestnik, Severny Arkhiv and other included the volume and details of information about the Kalmyks, the availability of historical and ethnographic information, the characteristics of the ethnic group and / or its individual representatives, the social status of the authors and the genre forms of the materials.The study has found that over the period under consideration the capital city magazines showed a gradually growing interest in the Kalmyk ethnic group, revealing its unusual history and culture to the Russian audience. The publications mainly belonged to contemporary authors, but texts from the XVII–XVIII centuries were also used, which made it possible to demonstrate the ideas about the Kalmyks at diff erent stages of their history.By the social status, the authors included offi cials, travelers, historians, ethnographers, writers, including the European ones and a Chinese one, which contributed to the creation of a diverse picture of the past and the present of the Kalmyk people. At the same time, the depth of topic coverage was determined by the breadth of the author’s outlook, their ability to observe, the degree of understanding and acceptance of a diff erent culture, and the place of the ethnic group in the overall plot of the text. The diff erence between empathy and immersion in culture led the authors in some cases to defi ne the Kalmyks as an “ignorant” people and, on the contrary, as a “shepherd”, demonstrating the highest level of originality. Most often, the texts created a collective image of the people or individual social groups. In historical discourse, the names of the Kalmyk rulers were called. Modern personalities were uncommon, as well as women – only three of them.The representation of the ethnic group was carried out mainly in voluminous genres – historical, ethnographic, historical-ethnographic and travel essays; less often – in the form of portrait sketches and reviews, which allowed magazines to provide diverse information and create a multifaceted image of the Kalmyk people.

The effect of IFRS convergence on risk disclosure: an investigation into the Indian accounting system

PurposeThis study aims to empirically investigate the effect of International Financial Reporting Standards (IFRS) convergence on corporate risk disclosure, with a particular emphasis on the quantity and coverage of risk information. The research also conducts economic benefit and cost analysis to investigate the economic implications that may arise from the transition to IFRS reporting.Design/methodology/approachA content analysis approach is used to measure two broader dimensions of risk disclosure, namely, risk disclosure quantity and risk topic coverage. Furthermore, using firm-fixed effect regression on a sample of 143 Indian-listed companies, this study investigates the variations in these risk disclosure dimensions before (2012–2016) and subsequent to (2017–2021) the convergence with IFRS.FindingsThe empirical results of this research demonstrate that IFRS convergence has led to a significant improvement in firms’ risk disclosure across several dimensions. Particularly, during the post-IFRS period, firms’ usage of risk-related words and sentences has considerably surged in MD&A, Notes and whole annual reports. In addition, upon IFRS convergence, firms’ risk descriptions have become more extensive and evenly distributed across risk topic categories. Moreover, the in-depth benefit and cost analysis revealed that firms reporting under IFRS benefit from decreased cost of equity capital, but they also incur a higher cost of audit fees.Originality/valueThis study contributes to the literature in two ways. First, this is the only study, to the best of the authors’ knowledge, to conduct a broader examination of the impact of mandatory IFRS convergence on corporate risk disclosure, with a major focus on quantity and coverage of risk information. Second, by conducting economic benefit and cost analysis, this study provides novel insights into the critical role of IFRS risk disclosures toward multiple economic outcomes.

Global root trait underrepresentation in Paleotropical communities: a qualitative analysis

Many ecosystem processes revolve around plant roots and the rhizosphere, but root trait knowledge has generally lagged behind aboveground plant traits from leaves and stems. In particular, root trait representation of Paleotropical species and tropical communities in modern trait databases remains poor, constraining our understanding of belowground processes in these regions. Therefore, we sought to examine the current state of root trait representation and associated topics in the Paleotropics to identify gaps and biases in the existing literature. Using an exhaustive literature scan, we compiled a list of publications that contained various belowground trait information. Subsequently, we utilized a statistical topic modeling method to analyze abstracts of publications in order to identify topics studied alongside root trait documentation. Finally, we consolidated trends in root trait coverage and topics across five geographical regions and four time periods to illustrate shifts in literature and knowledge of ecological processes revolving around roots. Root trait representation was heavily biased toward root biomass but other aspects of root systems such as physiology, architecture and anatomical traits remain underrepresented. We categorized 23 unique topics around root trait literature across eight categories: ecosystem productivity and biomass stocks, plant functional traits, resource availability, ecosystem processes and dynamics, mycorrhizal colonization, edaphic processes, seedling experiments, and global change and variation. Traits and topic coverage were unequally distributed across the Paletropics and exhibited a notable shift in focus from resource limitation and mycorrhizae research to root trait variation at large spatial and temporal scales over the last 50 years of root trait literature. Given these trends and the heterogenous effects global change exerts on the tropics at a regional scale, we provided several recommendations to facilitate inter-study comparisons of traits to advance the field’s understanding of belowground ecosystem processes in pantropical communities.

Topic and Accent Coverage in a Commercialized L2 Listening Test: Implications for Test-takers’ Identity

Abstract I analyzed a corpus of the international English language testing system (IELTS) comprising 256 listening sections (1996–2021). The primary objective of the study was to gain insights into the assumptions made by test designers regarding the real-life contexts that test-takers will encounter. Overall, 15 superordinate topic areas and 300 subtopics were identified in the corpus. There was relatively more diversity in topic coverage before 2000. However, the test did not incorporate texts that would address sociocultural matters related to local or international contexts. Additionally, English-as-L2 accents were virtually unrepresented with only three samples from 514 speakers, potentially suggesting a racialized perspective on the listening construct. I argue that it is possible that this way of testing promotes and normalizes test designers’ ideologies, while overlooking the importance of the diversity of domains that test-takers will encounter in daily life. I discuss the potential construction of test-takers’ identity through exposure to these topics and suggest that test designers may consider reevaluating topic and accent coverage in the test to improve fairness and equity in the test. Finally, I provide ideas on how the use of generative artificial intelligence (AI) can enhance quality of language assessments.

Insights from a Comparative Study on the Variety, Velocity, Veracity, and Viability of Crowdsourced and Professional Fact-Checking Services

The tension between the increasing need for fact-checking and the limited capacity of fact-check providers inspired several crowdsourced approaches to address this challenge. However, little is known about how effectively crowdsourced fact-checking might perform in the real world at a large scale. We fill this gap by evaluating a Taiwanese crowdsourced fact-checking community and two professional fact-checking sites from four dimensions: Variety, Velocity, Veracity, and Viability. Our analysis shows the different focus these two types of sites have in terms of topic coverage (variety) and demonstrates that while crowdsourced fact-checkers are much faster than professionals (velocity) to answer new requests, these fact-checkers often build on the existing professional knowledge for repeated requests. In addition, our findings indicate that the accuracy of the crowdsourced community (veracity) parallels that of the professional sources; and that the crowdsourced fact-checks are perceived quite close to professionals in terms of objectivity, clarity, and persuasiveness (viability).

Influencing Factors of School Organization and Management on University Ranking

The ranking is a quantitative presentation of the indicators of each university. The ranking can be regarded as a quantitative presentation of the comprehensive strength of the university. The comprehensive strength of each university is reflected in many aspects such as teaching quality, scientific research level, teaching staff, and subject coverage. The ranking quantifies and compares these strengths through a series of indicators, such as academic reputation, paper citations, and research funding. As the core of university operation, school organization is the direct factor that directly affects undergraduate universities. At present, it is found that school organizations are facing factors such as insufficient administrative management, insufficient teaching quality, and lack of international cooperation resources. How to rectify it, this article will give rationalization suggestions.

PubMed's core clinical journals filter: redesigned for contemporary clinical impact and utility.

The Core Clinical Journals (CCJ) list, produced by the U.S. National Library of Medicine (NLM), has been used by clinicians and librarians for half a century for two main purposes: narrowing a literature search to clinically useful journals and identifying high priority titles for library collections. After documentation of low usage of the existing CCJ, a review was undertaken to assess current validity, followed by an update to current clinical needs. As the subject coverage of the 50-year-old list had never been evaluated, the CCJ committee began its innovative step-wise approach by analyzing the existing subject scope. To determine whether clinical subjects had changed over the last half-century, the committee collected data on journal usage in hospitals and medical facilities, adding journal usage from Morning Report blogs recording the journal article citations used by physicians and residents in response to clinical questions. Patient-driven high-frequency diagnoses and subjects added contextual data by depicting the clinical environment. The analysis identified a total of 80 subjects and selected 241 journals for the updated Clinical Journals filter, based on actual clinical utility of each journal. These data-driven methods created a different framework for evaluating the structure and content of this filter. It is the real-world evidence needed to highlight CCJ clinical impact and push clinically useful journals to first page results. Since the new process resulted in a new product, the name warrants a change from Core Clinical Journals (CCJ) to Clinically Useful Journals (CUJ). Therefore, the redesigned NLM Core Clinical Journals/AIM set from this point forward will be referred to as Clinically Useful Journals (CUJ). The evidence-based process used to reframe evaluation of the clinical impact and utility of biomedical journals is documented in this article.

The right to free personal development as a manifestation of the connection between human dignity and freedom

Constitutional recognition of the worth of a human as the dominant value in the hierarchy of social ones activates the full potential of positive law to the maximum to secure it, in particular the mechanism of a general permissive type of legal regulation, which essentially presupposes freedom, and therefore the embodiment of the ideal of a free human person. The specificity of such regulation is expressed in the process of its social and contextual characteristics, namely, in the description of the scope and boundaries. Accordingly, it has been established that the development of the general permissive idea in the twentieth century shifted to the plane of “recognition of the worth of human dignity”, so the study of freedom within its interrelationship with human dignity forms the first approximate idea of the subject coverage of the general permission (as the basis of appropriate regulation). It has been established that such an interrelation is justified in the regulatory (international, national) and doctrinal context at the level of values and individual rights. It has also been proved that this interrelation is most clearly visible in the right to the free development of a person, which becomes a kind of “intersection”, the main point where dignity and freedom “are connected”.The national recognition of this right in the constitutions of different states has been investigated, in particular as the goals of the state; the highest values; the foundations of the political system and social peace; the personal independency right, including in the system of other personal rights. The peculiarities of its interpretation in German jurisprudence as an “unnamed”, “independent fundamental right to freedom”, which has been developed in two aspects: a) the general right of a person – its “comprehensive protection” from public and private interference, “strengthening” (additional) guarantee of human dignity (which promoted the formation of a kind of human rights methodology – “theory of spheres”). Its nature is analyzed from the point of view of the “human person essence (core)” and its components: human dignity, the fundamental right to informational self-determination, the right to life and limb; b) general freedom of action, which extends the sphere of defending freedom that is not covered by special constitutional rights.It has been found that this right was secured internationally with the expansion of its scope at the expense of the subject matter – the right of the people to self-determination. The constitutional practice of recognition of the right to free personal development in Ukraine has been analyzed and it is presumed to project the basic sphere of the generally permissive type of legal regulation

The application of big data technology in online subject education innovation research

This paper applies big data technology to promote the innovative development of online subject education and improve students' self-learning efficiency to promote innovative management interaction in the education industry. In the design process, big data technology is used to mine and analyze massive educational data, combine the learning needs of online subjects, and provide technical support for six application levels of the online subject education system. Document transformation of education data is performed through the DCF mechanism, and the synchronization time slot is divided into a safe time slot and a reservation time slot. Then, the adaptive recommendation function is used to extract valuable information from behavioral data for personalized learning resource pushing. To verify the practical application effect of big data technology in the online subject education innovation system, the simulation analysis results show that after applying big data technology, the recommended resources preference of the education system is above 86%, the subject coverage rate is 90.48%, and the performance of test scores is improved by 17.5% relative to Class C. This shows that big data technology optimizes the application mode of online subject education and can provide students with better-quality educational resources.

ID: 216812 Dynamic Stimulation Patterns Produce Varied Pain Coverage During Acute Spinal Cord Stimulation Evaluation

Introduction: Spinal Cord Stimulation (SCS) for chronic pain management typically uses static stimulation, a.k.a. tonic pulse-trains, where the amplitude, pulse width and rate of stimulation remain the same across time. Several SCS therapies, including both paresthesia-based that typically evoke “tingling” sensations and fast-acting paresthesia-free, are dependent on precise paresthesia-pain overlap. A recent publication demonstrates dynamic stimulation can improve efficacy of SCS in a preclinical rodent model1. We hypothesize that stimulation with dynamic pulse-trains may affect paresthesia-pain overlap. In this work, we evaluated paresthesia coverage of subjects experiencing static and dynamic SCS acutely.

Thirty years of academic finance

AbstractWe study how the financial literature has evolved in scale, research team composition, and article topicality across finance‐focused academic journals from 1992 to 2021. We document that the field has vastly expanded regarding outlets and published articles. Teams have become larger, and the proportion of women participating in research has increased significantly. Using the Structural Topic Model, we identify 45 topics discussed in the literature. We investigate the topic coverage of individual journals and can identify highly specialized and generalist outlets, but our analyses reveal that most journals have covered more topics over time, thus becoming more generalist. Finally, we find that articles with at least one woman author focus more on topics related to social and governance aspects of corporate finance. We also find that teams with at least one top‐tier institution scholar tend to focus more on theoretical aspects of finance.

Medication use by insurance coverage in subjects with coronary heart disease in the Southern Cone of Latin America

Abstract Funding Acknowledgements Type of funding sources: Other. Main funding source(s): This work was supported by the National Heart, Lung, and Blood Institute (NHLBI) grant number HHSN268200900029C. Background Clinical guidelines recommend cardioprotective medication use in coronary heart disease (CHD) patients. Underuse of these drugs is common among patients of low resources, which may be explained by insufficient access in the public sector. Aim We aim to assess medication use and barriers to care by insurance coverage in subjects with CHD in the Southern Cone of Latin America. Methods We analysed cross-sectional data from 593 participants with CHD residing in Argentina, Chile and Uruguay, within the CESCAS community-based cohort study. Participants were categorized as covered by public insurance only or having additional coverage (social security or private insurance). We calculated the prevalence of recommended medications use, mean number of medications, use of ≥ 1 and ≥ 2 drugs, and reported barriers to needed care in insured and uninsured participants. Differences between coverage groups were assessed with univariable and multivariable analysis (logistic and Poisson regression) adjusted by age, sex, previous revascularization, educational level and barriers. Results Medication use ranged from 39.8% (lipid-lowering) to 84.1% (antihypertensives). Mean number of medications was 1.8 (SE 0.1), 95.4% used ≥ 1 drugs, and 59.8% used ≥ 2 drugs. There were no significant differences by coverage in medication use, except for higher ACE-inhibitor and nitrate use among participants in the public sector (35.8% vs. 53.2%, p=0.001; and 1.5% vs. 5.2%, p=0.047 respectively). In the multivariable analysis, having public coverage only was not significantly associated with medication use, but it was with reporting barriers to care (OR 2.06, 95% CI 1.21-3.52). Conclusion Insurance coverage was not associated with the use of most medications in CHD patients in the Southern Cone of Latin America, possibly due to public health programs providing them free of charge. Uninsured participants more often face barriers to access medical care, and future studies should address these healthcare inequalities.

The Transformation of American Sex Education: Mary Calderone and the Fight for Sexual Health. Ellen S. More

Dr. Mary Steichen Calderone (1904–1998) was one of the best-known sex educators in the twentieth-century United States. However, her work has not received much attention until the publication of The Transformation of American Sex Education. This book approaches the history of twentieth-century American sex education through the lens of Calderone’s career and that of the Sexuality Information and Education Council of the United States (SIECUS), an advocacy organization that she cofounded in July 1964. However, the absence of an argument and uneven choices about topic coverage make Calderone and her achievements difficult to parse. Sex education in the US has received attention from historians including Jeffrey P. Moran (Teaching Sex, 2000), Janice M. Irvine (Talk about Sex, 2004), Susan K. Freeman (Sex Goes to School, 2008), Alexandra M. Lord (Condom Nation, 2010), and Courtney Q. Shah (Sex Ed, Segregated, 2015). None of them focus specifically on Calderone and SIECUS, or address the topic beyond the 1990s, and this book fills a gap in the literature by focusing on her and the organization and bringing the history of sex education up to the 2010s.

‘Oriental Culture Nucleus’: The P. M. Suski Collection of Chinese Rare Books at the University of Southern California

Abstract Dr Peter Marie Suski was born in Japan but migrated to the United States in 1898. He practiced as a physician in southern California but had a lifelong interest in the languages of East Asia and put together a valuable collection of books, which was donated to the University of Southern California in 1962. Revealing a little-known treasure at USC, this paper traces Suski’s life and book collecting through his autobiography and correspondence, and examines the subject coverage, research value and rarity of his collection of Chinese rare books. Several rare and special editions of Chinese rare book titles are highlighted in the paper, such as a 1618 manuscript copy of Shimo Juanhua 石墨鐫華, a 1748 palace edition of Yuanjian Leihan 淵鑑類函, and an 1825 first impression of Zijian 字鑑, all of which are featured in the USC Libraries online exhibit “Eastern Culture Nucleus: Chinese Rare Books in the USC Libraries (https://scalar.usc.edu/works/chinese-rare-books/index).”

Unveiling the present status of open access repositories: a comparative analysis of India and China

PurposeOpen access repository is an essential element of an organization's strategy for enhancing the visibility and accessibility of its intellectual output to a global audience. Owing to its importance, the study aims to explore the current status of open access repositories in India and China by analyzing the different characteristic features of repositories.Design/methodology/approachThe data for the study is collected from OpenDoar which is labeled as a quality assured repository directory across the globe. The country-wise contribution of Asian repositories is extracted from OpenDoar using various filtration options available in the repository. Further, the URL of every Indian and Chinese repository was manually accessed to gather the following metadata: Repository Type, Software Usage, Repository Interface Language, Year of Development, Subject Coverage, Content Coverage, and the utilization of Web 2.0 tools by repositories. FindingsThe findings of the study highlights that among the Asian countries, India is at 4th rank while China is at 5th rank in terms of repository count. The study depicts that India has shown more promising growth than China. However, both the countries mainly focused on institutional repositories while disciplinary, aggregated, and governmental repositories are very few in number, therefore building such repositories is the need of an hour. Dspace as the preferred software and English as a dominant interface language occupy the prominent places in the repositories of both countries. Moreover, the repositories of both countries have embraced web 2.0 tools like RSS 1.0, RSS 2.0 and Atom with little presence of social media tools.Research limitations/implicationsThe study has limitations, and results should be interpreted with caution. The comparison between the two countries is based on only one data source, i.e. OpenDoar. However, there is a possibility that future studies can take various repository directories as a data source that will give a clear picture of comparison.Originality/valueThe study can be beneficial to the policymakers and the administrators of these two regions as it will provide them a vivid picture of the diffrent characteristic features of their repositories so that they can formulate better policies that will be helpful to foster green open access.

Heming Yong and Jing Peng. 2022. A Sociolinguistic History of British English Lexicography

British English lexicography, which can be traced back to the Anglo-Saxon period, has a history of at least 400 years (Cowie 2009). Since the 1970s, many books have conducted an in-depth investigation into English lexicography from various perspectives. Some books intend to provide a comprehensive account (e.g. Zgusta 1971; Landau 1989; Svesnén 1993; Atkins and Rundell 2008; Fontenelle 2008; Svesnén 2009); some aim at a historical description (e.g. Collison 1982; Cowie 2002, 2009; Béjoint 2010; Miyoshi 2017); and some endeavour to reveal the current limitations of present-day English dictionaries and propose some solutions to these limitations (e.g. Dixon 2018). There are also some books focusing on the history of world lexicography (e.g. Considine 2019), or the lexicography of one single language (e.g. Yong and Peng (2008) on Chinese lexicography). However, most existing studies of British English lexicography are confined to individual lexicographic works of a particular period of time and pay little attention to the impacts of changes in society, culture, science, and technology on the evolution of lexicography. They lack historical continuity, subject coverage, and interdisciplinary perspectives, failing to fully reveal the evolutional characteristics and patterns of British English lexicography over different periods of time (p. 4).

Impact of social presence during COVID-19 and the implications for learning design

Globally, the COVID-19 pandemic has caused numerous economic, health and wellbeing issues and significantly disrupted the education sector. In response to the pandemic, universities scrambled to transition from face-to-face teaching to fully online teaching practices. With many institutions being unprepared for such a transition (Jung et al., 2021; Metcalfe, 2021), educators and students faced a variety of challenges, barriers, and opportunities (Garnett, 2021). Critically, one of the opportunities provided by the pandemic was for educators to re-evaluate and re-envision learning and teaching practices (Singh et al., 2022). One area ripe for re-evaluation is the nature of teacher-student relationships. While the teaching profession has long been associated with emotions and connection (Tackie, 2022), the shared experience of the pandemic saw students and their teachers finding themselves in the same virtual lifeboat with the pandemic becoming a universal factor for students and educators, making the processes of learning and teaching even more challenging (Mitchell et al, 2021). Additionally, educators - often called on to act as counsellors and therapists (Tackie, 2022) - found themselves during the pandemic having to manage both their own and their students’ well-being. This Pecha Kucha provides preliminary results and associated reflections of a study undertaken at the University of New England (UNE) while learning, teaching and assessment were being transitioned to fully online delivery. Despite, having a large proportion of classes being delivered online prior to the pandemic, challenges were still faced by UNE staff as they managed both their own and their students’ well-being. Here, technology played a critical role in brokering the shared experiences between students and staff with evidence suggesting that social presence was a critical factor in fostering a greater sense of connection amongst members of the university learning community. In learning design, the importance of connections, interactions, and the socio-emotional aspects of learning (i.e., elements that characterize social presence) are often overlooked and underrated (Ensmann et al., 2021). Consequently, the focus tends to fall on subject matter content coverage (i.e., teaching presence and cognitive presence) at the expense of interpersonal relations (i.e., social presence) (Patel, 2021). Our results suggest a re-evaluation of the importance of interpersonal relationships fostered through social presence is necessary to help ensure positive and well-balanced online learning experiences. At UNE, the interpersonal relationships that emerged during the pandemic - although largely unplanned and unintended - were nevertheless effective in supporting and maintaining student and staff well-being. Due to the critical role interpersonal relationships were shown to play, they should not be left to chance. Accordingly, the building of interpersonal relationships and the fostering of social presence should be intentional outcomes of every learning design.

Tiered sentence based topic model for multi-document summarization

In this work, a probabilistic two level topic model named Tiered Sentence based Topic Model is proposed which models the document at sentence and word levels and infer hierarchical latent topics for sentences. The proposed model uses two latent variables for the generation of words- a super topic and a subtopic for each sentence of the document, to model word groupings at sentence level. Popular super topics identify general theme of the documents and are used for selecting summary sentences. The model parameters are used for ranking sentences considering sentence importance and topic coverage. Collapsed Gibbs sampling is used for inference and parameter estimation. The proposed model is used to compare with two sentence based topic models- SenLDA and LDCC on query focused multi-document summarization task, over standard DUC2005 dataset using ROUGE-1 and ROUGE-2 precision and recall scores. The proposed model performs better than Latent Dirichlet Allocation and SenLDA but has been outperformed by LDCC.

A global research trend in AUM meditation

The scientific community has long been interested in mantras and meditation. However, very little study has been done on specific mantras such as AUM. The major goal of this bibliometric study is to aid AUM meditation research by finding all connected publications and subject coverage, as well as uncovering historical trends, active research domains, prominent journals, authors, organizations, and nations, as well as linkages between them. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria were used to search the Dimensions.ai database for AUM-related articles. VOS-viewer was utilized to reveal emergent trends and transitory patterns in the literature, as well as to demonstrate international collaboration, organizational coupling, and co-cited author networks. After a thorough screening and extensive article reading, fifty studies were chosen for the study. According to the findings, India produced the majority of data. More than half (62%) of the publications were in the field of “Medical and Health”, and about one-sixth (16%) were in “Psychology and Cognitive Sciences”. Based on Publications “The International Journal of Yoga” has the most publications (26.66%) and citations (40.87%). The strongest linkages are found in “Venkatasubramanian, Ganesan (952)”, “India (101)”, and “National Institute of Mental Health and Neurosciences (192)”. This bibliometric analysis synthesized and illustrated 48 years of AUM meditation research, indicating key highlights, and rising trends. The findings of the study contribute to the creation of a platform for future research in the field of AUM meditation.

ECANP: A Topic Influence Evaluation Model for Hot Topics.

Social network is an important product of industrial society. In recent years, the research related to hot topics has focused on topic detection, topic trend prediction, and topic tracking. However, the important role of topic influence evaluation in hot topic research has not received enough attention, which leads the problem of inaccurate influence calculation. In order to solve the above problems, this paper proposes a novel model to evaluate the real-time relative influence of topics in social network. The proposed model can quantify the influence of topics, and some influential factors which determine topic hotness will be analyzed and identified. In this model, five impact indicators are defined, namely user engagement, topic coverage, topic activity, topic persistence, and topic novelty to consider the topic characteristics more finely. Moreover, the proposed model not only consider traditional simple factors of like, forward and comments, but also pay attention to the relative influence and time attenuation characteristics of the topics. Further, the experimental results show that our method could quickly aggregate the influence factors of hot topics and accurately provide the influence indicator of topics.
