A parallel optimization and transfer learning approach for summarization in electrical power systems

Transfer learning approaches in natural language processing have been explored and evolved as a potential solution for solving many problems in recent days. The current research on aspect-based summarization shows unsatisfactory accuracy and low-quality generated summaries. Additionally, the potential advantages of combining language models with parallel processing have not been explored in the existing literature. This paper aims to address the problem of aspect-based extractive text summarization using a transfer learning approach and an optimization method based on map reduce. The proposed approach utilizes transfer learning with language models to extract significant aspects from the text. Subsequently, an optimization process using map reduce is employed. This optimization framework includes an in-node mapper and reducer algorithm to generate summaries for important aspects identified by the language model. This enhances the quality of the summary, leading to improved accuracy, particularly when applied to electrical power system documents. By leveraging the strengths of natural language models and parallel data processing techniques, this model presents an opportunity to achieve better text summary generation. The performance metric used is accuracy, measured with the ROUGE tool, incorporating precision, recall and f-measure. The proposed model demonstrates a 6% improvement in scores compared to state-of-the-art techniques.

Bridging the Gap Between Urological Research and Patient Understanding: The Role of Large Language Models in Automated Generation of Layperson's Summaries.

This study assessed ChatGPT's ability to generate readable, accurate, and clear layperson summaries of urological studies, and compared the performance of ChatGPT-generated summaries with original abstracts and author-written patient summaries to determine its effectiveness as a potential solution for creating accessible medical literature for the public. Articles from the top 5 ranked urology journals were selected. A ChatGPT prompt was developed following guidelines to maximize readability, accuracy, and clarity, minimizing variability. Readability scores and grade-level indicators were calculated for the ChatGPT summaries, original abstracts, and patient summaries. Two MD physicians independently rated the accuracy and clarity of the ChatGPT-generated layperson summaries. Statistical analyses were conducted to compare readability scores. Cohen's κ coefficient was used to assess interrater reliability for correctness and clarity evaluations. A total of 256 journal articles were included. The ChatGPT-generated summaries were created with an average time of 17.5 (SD 15.0) seconds. The readability scores of the ChatGPT-generated summaries were significantly better than the original abstracts, with Global Readability Score 54.8 (12.3) vs 29.8 (18.5), Flesch Kincade Reading Ease 54.8 (12.3) vs 29.8 (18.5), Flesch Kincaid Grade Level 10.4 (2.2) vs 13.5 (4.0), Gunning Fog Score 12.9 (2.6) vs 16.6 (4.1), Smog Index 9.1 (2.0) vs 12.0 (3.0), Coleman Liau Index 12.9 (2.1) vs 14.9 (3.7), and Automated Readability Index 11.1 (2.5) vs 12.0 (5.7; P < .0001 for all except Automated Readability Index, which was P = .037). The correctness rate of ChatGPT outputs was >85% across all categories assessed, with interrater agreement (Cohen's κ) between 2 independent physician reviewers ranging from 0.76-0.95. ChatGPT can create accurate summaries of scientific abstracts for patients, with well-crafted prompts enhancing user-friendliness. Although the summaries are satisfactory, expert verification is necessary for improved accuracy.

From Data to Human-Readable Requirements: Advancing Requirements Elicitation through Language-Transformer-Enhanced Opportunity Mining

In this research, we present an algorithm that leverages language-transformer technologies to automate the generation of product requirements, utilizing E-Shop consumer reviews as a data source. Our methodology combines classical natural language processing techniques with diverse functions derived from transformer concepts, including keyword and summary generation. To effectively capture the most critical requirements, we employ the opportunity matrix as a robust mechanism for identifying and prioritizing urgent needs. Utilizing transformer technologies, mainly through the implementation of summarization and sentiment analysis, we can extract fundamental requirements from consumer assessments. As a practical demonstration, we apply our technology to analyze the ratings of the Amazon echo dot, showcasing our algorithm’s superiority over conventional approaches by extracting human-readable problem descriptions to identify critical user needs. The results of our study exemplify the potential of transformer-enhanced opportunity mining in advancing the requirements-elicitation processes. Our approach streamlines product improvement by extracting human-readable problem descriptions from E-Shop consumer reviews, augmenting operational efficiency, and facilitating decision-making. These findings underscore the transformative impact of incorporating transformer technologies within requirements engineering, paving the way for more effective and scalable algorithms to elicit and address user needs.

Crisis event summary generative model based on hierarchical multimodal fusion

How to quickly obtain information about crisis events on social media such as Twitter and Weibo is crucial for follow-up rescue work and the promotion of postdisaster reconstruction. Therefore, it is very important to obtain useful information through multimodal summary generation technology. The current technology for generating crisis event summaries is mainly affected by unimodal bias and disregards the diversity of information in text and images. To solve these problems, this paper proposes a hierarchical multimodal crisis event summary generation model based on the modal alignment premise and hierarchical thinking. First, the visual context vector and text context vector are obtained, and then the hierarchical multimodal pointer model is employed to generate the text summary. Thus, the modal deviation is solved. Second, to select high-quality images, this paper proposes a dynamic selection strategy, which to some extent considers the requirements of the high correlation between text and images and the diversity of crisis information. Last, the experimental results based on the crisis event data in the MSMO dataset show that the proposed model achieves good performance in the summary generation and image selection of crisis events.

End-to-end hard constrained text generation via incrementally predicting segments

Hard-constrained text generation is an important task that requires generating fluent sentences to include several specific keywords. It has numerous real-world applications, such as advertisement generation, keyword-based summary generation, and query rewriting. Although previous plug-and-play approaches like enhanced beam search and stochastic search have been proven effective, they lack time efficiency and may reduce the quality of generated sentences. While end-to-end methods based on seq2seq models are superior in speed, they cannot guarantee that outputs satisfy all constraints. In this work, we propose a novel end-to-end method for lexically constrained text generation via incrementally predicting segments (IPS) between every two adjacent lexical constraints using seq2seq models. Our approach guarantees that all constrained keywords will be included in the generated sentence. The experimental results show that our method not only satisfies all lexical constraints but also achieves state-of-the-art performance. Our code and data will be available at https://github.com/blcuicall/IPS.

G-DCS: GCN-Based Deep Code Summary Generation Model

&lt;p&gt;In software engineering, software personnel faced many large-scale software and complex systems, these need programmers to quickly and accurately read and understand the code, and efficiently complete the tasks of software change or maintenance tasks. Code-NN is the first model to use deep learning to accomplish the task of code summary generation, but it is not used the structural information in the code itself. In the past five years, researchers have designed different code summarization systems based on neural networks. They generally use the end-to-end neural machine translation framework, but many current research methods do not make full use of the structural information of the code. This paper raises a new model called G-DCS to automatically generate a summary of java code; the generated summary is designed to help programmers quickly comprehend the effect of java methods. G-DCS uses natural language processing technology, and training the model uses a code corpus. This model could generate code summaries directly from the code files in the coded corpus. Compared with the traditional method, it uses the information of structural on the code. Through Graph Convolutional Neural Network (GCN) extracts the structural information on the code to generate the code sequence, which makes the generated code summary more accurate. The corpus used for training was obtained from GitHub. Evaluation criteria using BLEU-n. Experimental results show that our approach outperforms models that do not utilize code structure information.&lt;/p&gt; &lt;p&gt;&amp;nbsp;&lt;/p&gt;

Summarizing source code with Heterogeneous Syntax Graph and dual position

Code summarization attempts to summarize the semantics of source code by automatically producing brief natural-language descriptions. Most existing work proposes to learn from the Abstract Syntax Tree (AST) and plain text of source code for summary generation. However, little attention has been paid to the structural heterogeneity and layout features of source code. In this paper, we present a novel framework titled HetSum to address these issues. Specifically, a Heterogeneous Syntax Graph (HSG) is first built by designing six types of augmented edges in AST, which indicates the heterogeneous structure of source code. Meanwhile, a dual position is designed for each token in the source code by considering the layout information. Moreover, we develop a heterogeneous graph neural network in HetSum to encode the HSG while extracting the code layout features with the Transformer encoder. By assimilating the learned code token vectors into the HSG encoder, HetSum can capture the relations between its two encoders for improved code representation. To facilitate the generation of high-quality summaries, we integrate a copying mechanism into the decoding procedure while expanding the Transformer decoding sublayer. Extensive experiments on the Java and Python datasets prove that HetSum is superior to seventeen state-of-the-art baselines. To promote reproducibility studies, we make the implementation of HetSum available at https://github.com/GJCEXP/HETSUM.

Domain adaptation assisted automatic real-time human-based video summarization

The video summarization plays a momentous role for real-time surveillance for detection of suspicious human activities in public scenes. However, efficient, and accurate human-centric video summarization in real-time videos is still a challenging issue due to several inconsistencies such as noise, illumination effects, scale, or rotational variance, etc. Though, several prominent research studies are available related to human activities detection but a robust human-centric video summarization approach is a major issue. In this research, we expound an efficient video summary generation model (ReHuSum) that creates a short summary with human. Our approach employs the conception of domain adaptation for efficient summarization via transferring the knowledge of a potent pre-trained benchmark Inception-v3 model. Additionally, a frame differencing redundancy removal technique is adopted that aids in generating a precise and accurate video summary with human. Our model generates efficient short summaries from real-time videos with an overall human detection accuracy of 99.97%. Besides, we present two novel qualitative metrics namely; summarization rate (Summrate) and summarization loss (Summloss) for assessing the efficacy of overall summarization. The approach generates a real-time human-based summary of 46s with a (Summrate) of 98.7% and (Summloss) of 0.013 for an outdoor CCTV with a duration of 25.2 min. Similarly, an indoor CCTV of 40.10 min duration is summarized to 44s at a (Summrate) of 96.5% and (Summloss) of 0.035. The model can be utilized in real-time security applications (i.e., border or home surveillance, critical infrastructure, smart cities, etc.) to generate accurate video summaries with human.

An optimized hybrid deep learning model based on word embeddings and statistical features for extractive summarization

Extractive summarization has recently gained significant attention as a classification problem at the sentence level. Most current summarization methods rely on only one way of representing sentences in a document (i.e., extracted features, word embeddings, BERT embeddings). However, classification performance and summary generation quality will be improved if we combine two ways of representing sentences. This paper presents a novel extractive text summarization method based on word embeddings and statistical features of a single document. Each sentence is encoded using a Convolutional Neural Network (CNN) and a Feed-Forward Neural Network (FFNN) based on word embeddings and statistical features. CNN and FFNN outputs are concatenated to classify the sentence using a Multilayer Perceptron (MLP). In addition, hybrid model parameters are optimized by the KerasTuner optimization technique to determine the most efficient hybrid model. The proposed method was evaluated on the standard Newsroom dataset. Experiments show that the proposed method effectively captures the document’s semantic and statistical information and outperforms deep learning, machine learning, and state-of-the-art approaches with scores of 78.64, 74.05, and 72.08 for ROUGE-1 ROUGE-2, and ROUGE-L, respectively.

Survey on abstractive text summarization using pretraining models and their developments

In these years, pre-training models gain a lot of attention in the summary generation area and demonstrate new possibilities for improving the sequence-to-sequence attention framework. This survey conducts a comprehensive overview of BERT-based pre-training models that can be used in abstractive summaries. Firstly, the BERT model is introduced as a typical pre-training model, followed by baseline models inspired by it. Then problems and developments of previous models are discussed including some recent SOTA approaches. Apart from that, some datasets used for models are demonstrated with main features. Besides, the commonly used evaluation methods are introduced. Last but not least, several potential research directions are suggested.

Data Summarization Web Application

Abstract: As there is an increase in the usage of digital applications, the availability of data generated has increased to a tremendous scale. Data is an important component in almost every domain where research and analysis are required to solve problems. It is available in a structured or unstructured format. Therefore, to get corresponding data as per the application purpose, easily and quickly from different sources of data on the internet, an online content summarizer is desired. Summarizers make it easier for users to understand the content without reading it completely. Abstractive Text Summarizer helps in defining the content by considering the important words and helps in creating summaries that are in a human-readable format. The main aim is to make summaries in such a way that they should not lose their context. Various Neural Network models are employed along with other machine translation models to bring about a concise summary generation. This paper aims to highlight and study the existing contemporary models for abstractive text summarization and also to explore areas for further research

Plan and generate: Explicit and implicit variational augmentation for multi-document summarization of scientific articles

Multi-Document Summarization of Scientific articles (MDSS) is a challenging task that aims to generate concise and informative summaries for multiple scientific articles on a particular topic. However, despite recent advances in abstractive models for MDSS, grammatical correctness and contextual coherence remain challenging issues. In this paper, we introduce EDITSum, a novel abstractive MDSS model that leverages sentence-level planning to guide summary generation. Our model incorporates neural topic model information as explicit guidance and sequential latent variables information as implicit guidance under a variational framework. We propose a hierarchical decoding strategy that generates the sentence-level planning by a sentence decoder and then generates the final summary conditioned on the planning by a word decoder. Experimental results show that our model outperforms previous state-of-the-art models by a significant margin on ROUGE-1 and ROUGE-L metrics. Ablation studies demonstrate the effectiveness of the individual modules proposed in our model, and human evaluations provide strong evidence that our model generates more coherent and error-free summaries. Our work highlights the importance of high-level planning in addressing intra-sentence errors and inter-sentence incoherence issues in MDSS.

Multilingual Text Summarization for German Texts Using Transformer Models

The tremendous increase in documents available on the Web has turned finding the relevant pieces of information into a challenging, tedious, and time-consuming activity. Text summarization is an important natural language processing (NLP) task used to reduce the reading requirements of text. Automatic text summarization is an NLP task that consists of creating a shorter version of a text document which is coherent and maintains the most relevant information of the original text. In recent years, automatic text summarization has received significant attention, as it can be applied to a wide range of applications such as the extraction of highlights from scientific papers or the generation of summaries of news articles. In this research project, we are focused mainly on abstractive text summarization that extracts the most important contents from a text in a rephrased form. The main purpose of this project is to summarize texts in German. Unfortunately, most pretrained models are only available for English. We therefore focused on the German BERT multilingual model and the BART monolingual model for English, with a consideration of translation possibilities. As the source of the experiment setup, took the German Wikipedia article dataset and compared how well the multilingual model performed for German text summarization when compared to using machine-translated text summaries from monolingual English language models. We used the ROUGE-1 metric to analyze the quality of the text summarization.

Completing Function Documentation Comments Using Structural Information

Source code comments are a cornerstone of software documentation facilitating feature development and maintenance. Well-defined documentation formats, like Javadoc, make it easy to include structural metadata used to, for example, generate documentation manuals. However, the actual usage of structural elements in source code comments has not been studied yet. We investigate to which extent these structural elements are used in practice and whether the added information can be leveraged to improve tools assisting developers when writing comments. Existing research on comment generation traditionally focuses on automatic generation of summaries. However, recent works have shown promising results when supporting comment authoring through a next-word prediction. In this paper, we present an in-depth analysis of commenting practice in more than 18K open-source projects written in Python and Java showing that many structural elements, particularly parameter and return value descriptions are indeed widely used. We discover that while a majority are rather short at about 6 to 9 words, many are several hundred words in length. We further find that Python comments tend to be significantly longer than Java comments, possibly due to the weakly-typed nature of the former. Following the empirical analysis, we extend an existing language model with support for structural information, substantially improving the Top-1 accuracy of predicted words (Python 9.6%, Java 7.8%).

However, databases of this size require data manipulation skills that pose a barrier to many potential users. Here, we present rWCVP, an open-source R package that aims to facilitate the use of the WCVP by providing clear, intuitive functions to execute many common tasks. These functions include taxonomic name reconciliation, geospatial integration, mapping and generation of multiple different summaries of the WCVP in both data and report format. We have included extensive documentation and tutorials, providing step-by-step guides that are accessible even to users with minimal programming experience. rWCVP is available on cran and GitHub.

LEMMA-ROUGE: An Evaluation Metric for Arabic Abstractive Text Summarization

High morphological languages are characterized by complex inflections and derivations, which can present challenges for natural language processing tasks such as summarization. Abstractive text summarization aims to generate a summary by understanding the meaning of the text, rather than solely relying on the words used in the original source. However, few works address the generation of abstractive summaries due to its complexity. One of the challenges is the absence of a reliable metric to evaluate the performance of abstractive summaries. This paper proposes a lemma-based ROUGE metric and investigates the effectiveness of normalization forms in the similarity matching of the ROUGE metric for evaluating abstractive text summarization systems. We use Arabic as a case study and compare results involving different forms of the word: as is, stem-based, and lemma-based. The results show that the lemma-based form achieves higher ROUGE scores than the other forms. The findings emphasize the impact of morphological complexity on the performance of abstractive text summarization systems.

Key News Event Detection and Event Context Using Graphic Convolution, Clustering, and Summarizing Methods

The detection of key events and identification of the events’ context have been widely studied to detect key events from large volumes of online news and identify trends in such events. In this paper, we propose a Key News Event Detection and Context Method based on graphic convolving, clustering, and summarizing methods. Our method has three main contributions: (1) We propose the use of position vectors as time-embedding feature representations and concatenate semantic and time-embedding features as node features of the graph to distinguish different nodes of the graph. Additionally, a temporal nonlinear function was constructed using time embedding to objectively describe the effect of time on the degree of association between nodes. (2) We update the graph nodes using a graph convolutional neural network to extract deep semantic information about individual nodes of a high-quality phrase graph, thereby improving the clustering capability of graph-based key event detection. (3) We apply a summary generation algorithm to a subset of news data for each key event. Lastly, we validated the effectiveness of our proposed method by applying it to the 2014 Ebola dataset. The experimental results indicate that our proposed method can effectively detect key events from news documents with high precision and completeness while naturally generating the event context of key events, as compared to EvMine and other existing methods.

COVID-19 vaccination telephone outreach: an analysis of the medical student experience

ABSTRACT Introduction The COVID-19 pandemic diminished opportunities for medical students to gain clinical confidence and the ability to contribute to patient care. Our study sought out to understand the value of telephone outreach to schedule COVID-19 vaccines on medical student education. Materials and Methods Forty students engaged in telephone outreach targeting patients aged 65+ without active patient portals to schedule COVID-19 vaccines. Data consisted of a single administration retrospective pre/post survey inquiring about what students learned, expectations, other health-care processes that would benefit from outreach, and interest in a population health elective. Likert items were analyzed and open response analysis involved inductive coding and generation of thematic summaries by condensing codes into broader themes. Demographic data of patients called and subsequently received the vaccine were also collected. Results There were 33 survery respondents. There was a statistically significant increase in net comfortability for pre-clerkship students for documenting in Epic, providing telehealth care, counseling on common health-care myths, having challenging conversations, cold-calling patients, and developing an initial trusting relationship with patients. The majority called and who received the vaccine were non-Hispanic Black, within the high SVI category, and had Medicare and/or Medicaid. Qualitative data showed that students emphasized communication, the role of trusted messengers, the need to be open minded, and meeting patients where they are. Discussion Engaging students in telephone outreach early in the COVID-19 pandemic provided students the opportunity to develop their skills as physicians-in-training, contribute to combating the ongoing pandemic, and add value to the primary care team. This experience allowed students to practice patience, empathy, and vulnerability to understand why patients had not received the COVID-19 vaccine; this was an invaluable experience that helped students develop the skills to become empathetic and caring physicians, and supports the continued role of telehealth in future medical school curriculum.

Extractive Text Summarization Using Deep Learning for Tigrigna Language

With the ever-increasing amounts of textual material such as web pages, news articles, blogs, microblogs, and similar, the Internet became the massive body of unstructured information. In this paper to deal with the issues for the availability of more and more information with less time, the extractive text summarization using the deep learning model was used. In this paper, the proposed approach uses three basic stages of feature extraction, feature enhancement, and summary generation of the given news article to extract the core information, to produce well understandable summary and save reader’s time. In the feature extraction, We explore various features to improve the extracted sentences to the summary by the score and rank of the extracted features matrix by calculating the top thematic words, paragraph segmentation, sentences length & position, proper nouns, and TF-ISF, and the sum of the feature vector given to RBM to enhance the extracted feature vector and finally generate the final summarization by taking top high scores and 50% 0f the sum second higher scores from the enhanced feature extracted scores. For experimenting purpose, we have used 10 news articles from the total gathered news articles gathered from BBC-Tigrigna, Fana-Tigrigna and VOA-Tigrigna news website. The evaluation of the extracted summary was evaluated using Recall-Oriented Understudy for Gisting Evaluation (ROUGE) to compare the system extracted summary with the reference / manual summary prepared by human experts. According the experimentation, the average score of ROUG-1 shows 49% for recall, 39% precession, 42% for F-score and for the ROUGE-2 shows that 32% recall, 26% precession and 28% for F-score, for ROUGE-l also shows that 39% of recall, 33% of Precession, and 35% of F-scores. The result shows the proposed approach have higher result in Rouge-1 and the F-score or harmonic mean of precision and recall is 42% and it solves the problems of information overloading in the ever-increasing available news articles by generating the extractive summarizations.

A High-Precision Two-Stage Legal Judgment Summarization

Legal judgments are generally very long, and relevant information is often scattered throughout the text. To complete a legal judgment summarization, capturing important, relevant information comprehensively from a lengthy text is crucial. The existing abstractive-summarization models based on pre-trained language have restrictions on the length of an input text. Another concern is that the generated summaries have not been well integrated with the legal judgment’s technical terms and specific topics. In this paper, we used raw legal judgments as information of different granularities and proposed a two-stage text-summarization model to handle different granularities of information. Specifically, we treated the legal judgments as a sequence of sentences and selected key sentence sets from the full texts as an input corpus for summary generation. In addition, we extracted keywords related to technical terms and specific topics in the legal texts and introduced them into the summary-generation model as an attention mechanism. The experimental results on the CAIL2020 and the LCRD datasets showed that our model achieved an overall 0.19–0.41 improvement in its ROUGE score, as compared to the baseline models. Further analysis also showed that our method could comprehensively capture essential and relevant information from lengthy legal texts and generate better legal judgment summaries.
