Abstract

Topic modeling is a Natural Language Processing technique that has gained popularity over the last ten years, with applications in multiple fields of knowledge. However, there is insufficient empirical evidence to show how this field of study has developed over the years, as well as the main models that have been applied in different contexts. The objective of this paper is to analyze the evolution of the topic modeling technique, the main areas in which it has been applied, and the models that are recommended for specific types of data. The methodology applied is based on bibliometric analysis. First, we searched the Web of Science and the Scopus databases. We then used scientometric techniques and a Tree of Science methodology, which allowed us to analyze the search results from the perspectives of classics, structure, and trends. The results show that the USA and China are among the most productive countries in this field and the applications have been mainly in the identification of sub-topics in short texts, such as social networks and blogs. The main conclusion of this work is that topic modeling is a versatile technique that can complement systematic literature reviews and that has been well-received in different academic and research contexts. The results of this study will help researchers and academics to recognize the importance of these techniques for reviewing large volumes of unstructured information, such as research articles, and in general, for systematic literature reviews. INDEX TERMS Literature review, machine learning, natural language processing, scientometrics, topic modeling.

Quick Insight of Research Literature Using Topic Modeling
Sharvari C Tamane

2019

With the development in Information technology and advancement in education and research, a huge number of research publications and articles are generated every year. Crucial knowledge and information about innovative technology are embedded in these documents. It has become necessary to find a text analytics technique that gives quick insight into the research content from such enormous unstructured text data. Here we proposed information retrieval technique using topic modeling for taking quick outlook of the data. Latent Dirichlet is a generative probabilistic model which uses probability distribution of words in document to extract theme of documents. Topics generated show many hidden themes, correlated terminologies to main theme of documents which gives a quick overview of these documents. In this work Blockchain Technology, emergent technology publications are considered.

In Search of Theories in Library and Information Science: A Topic Modeling Approach
Bijan Kumar Roy

IJISM

Finding relevant topics or extracting useful information from a large corpus of data has been challenging for academicians and topic modeling, a machine learning algorithm, has emerged as an alternative technique for discovering the underlying semantic structure of large, unstructured collections of documents. Our objectives are to find out the different topics covered in corpus data and group them by those topics, to show the development of research in different aspects of LIS; and to show the application and use of theories from other domains used in the LIS domain. We apply several open-source software used for topic modeling, such as LDA (Latent Dirichlet Allocation), Gensim, Jupiter Notebook, ASReview, OpenRefine, etc, to extract the key topics from the titles and abstracts. The results of this study are summarized mainly into three sets viz. identification of specific topics, word clouds, trends in subjects, and use and applications of theories in this domain. The model may help policymakers, funding agencies, and the government understand the current and future state of research and take corrective actions to fill the gaps in the literature of expert systems and applications. It also helps library professionals, classificationists, and researchers identify relevant topics covered in an unstructured long text and reduce information overload by removing unnecessary research documents.

A scoping review of topic modelling on online data
Indonesian Journal of Electrical Engineering and Computer Science

The Indonesian Journal of Electrical Engineering and Computer Science (IJEECS), 2023

With the increasing prevalence of unstructured online data generated (e.g., social media, online forums), mining them is important since they provide a genuine viewpoint of the public. Due to this significant advantage, topic modelling has become more important than ever. Topic modelling is a natural language processing (NLP) technique that mainly reveals relevant topics hidden in text corpora. This paper aims to review recent research trends in topic modelling and state-of-the-art techniques used when dealing with online data. Preferred reporting items for systematic reviews and meta-analysis (PRISMA) methodology was used in this scoping review. This study was conducted on recent research works published from 2020 to 2022. We constructed 5 research questions for the interest of many researchers. 36 relevant papers revealed that more work on non-English languages is needed, common pre-processing techniques were applied to all datasets regardless of language e.g., stop word removal; latent dirichlet allocation (LDA) is the most used modelling technique and also one of the best performing; and the produced result is most evaluated using topic coherence. In conclusion, topic modelling has largely benefited from LDA, thus, it is interesting to see if this trend continues in the future across languages.

A Survey of Topic Modeling in Text Mining
Khalid Alfalqi

International Journal of Advanced Computer Science and Applications, 2015

Topic models provide a convenient way to analyze large of unclassified text. A topic contains a cluster of words that frequently occur together. A topic modeling can connect words with similar meanings and distinguish between uses of words with multiple meanings. This paper provides two categories that can be under the field of topic modeling. First one discusses the area of methods of topic modeling, which has four methods that can be considerable under this category. These methods are Latent semantic analysis (LSA), Probabilistic latent semantic analysis (PLSA), Latent Dirichlet allocation (LDA), and Correlated topic model (CTM). The second category is called topic evolution models, which model topics by considering an important factor time. In the second category, different models are discussed, such as topic over time (TOT), dynamic topic models (DTM), multiscale topic tomography, dynamic topic correlation detection, detecting topic evolution in scientific literature, etc.

Enhancing the Literature Review Using Author-Topic Profiling
Santipong Thaiprayoon

Lecture Notes in Computer Science, 2008

In this paper, we utilize bibliographic data for identifying author-topic relations which can be used to enhance the traditional literature review. When writing a research paper, researchers often cite on the order of tens of references which do not provide the complete coverage of the research context especially when the targeted research is multidisciplinary. Author-topic profiling can help researchers discover a broader picture of their topic of interest including topical relationships and research community. We apply the Latent Dirichlet Allocation (LDA) to generate multinomial distributions over words and topics to discover author-topic relations from text collections. As an illustration, we apply the methodology to bibliographic abstracts related to Emerging Infectious Diseases (EIDs) research topic.

Bibliometric Impact Measures Leveraging Topic Analysis
Andrew McCallum

Measurements of the impact and history of research literature provide a useful complement to scientific digital library collections. Bibliometric indicators have been extensively studied, mostly in the context of journals. However, journal-based metrics poorly capture topical distinctions in fast-moving fields, and are increasingly problematic with the rise of open-access publishing. Recent developments in latent topic models have produced promising results for automatic sub-field discovery. The fine-grained, faceted topics produced by such models provide a clearer view of the topical divisions of a body of research literature and the interactions between those divisions. We demonstrate the usefulness of topic models in measuring impact by applying a new phrase-based topic discovery model to a collection of 300,000 Computer Science publications, collected by the Rexa automatic citation indexing system.

Semantic Academic Profiler (SAP): a framework for researcher assessment based on semantic topic modeling
Felipe Viegas

Scientometrics

Recent efforts have focused on identifying multidisciplinary teams and detecting co-Authorship Networks based on exploring topic modeling to identify researchers' expertise. Though promising, none of these efforts perform a real-life evaluation of the quality of the built topics. This paper proposes a Semantic Academic Profiler (SAP) framework that allows summarizing articles written by researchers to automatically build research profiles and perform online evaluations regarding these built profiles. SAP exploits and extends state-of-the-art Topic Modeling strategies based on Cluwords considering n-grams and introduces a new visual interface able to highlight the main topics related to articles, researchers and institutions. To evaluate SAP's capability of summarizing the profile of such entities as well as its usefulness for supporting online assessments of the topics' quality, we perform and contrast two types of evaluation, considering an extensive repository of Brazilian curricula vitae: (1) an offline evaluation, in which we exploit a traditional metric (NPMI) to measure the quality of several data representations strategies including (i) TFIDF, (ii) TFIDF with Bi-grams, (iii) Cluwords, and (iv) CluWords with Bi-grams; and (2) an online evaluation through an A/B test where researchers evaluate their own built profiles. We also perform an online assessment of SAP user interface through a usability test following the SUS methodology. Our experiments indicate that the CluWords with Bigrams is the best solution and the SAP interface is very useful. We also observed essential differences in the online and offline assessments, indicating that using both together is very important for a comprehensive quality evaluation. Such type of study is scarce in the literature and our findings open space for new lines of investigation in the Topic Modeling area.

Topic modelling through the bibliometrics lens and its technique
Bayode Ogunleye

Artificial Intelligence Review, 2025

Topic modelling (TM) is a significant natural language processing (NLP) task and is becoming more popular, especially, in the context of literature synthesis and analysis. Despite the growing volume of studies on the use of and versatility of TM, the knowledge of TM development, especially from the perspective of bibliometrics analysis is limited. To this end, this study evaluated TM research using two techniques namely, bibliometrics analysis and TM itself to provide the current status and the pathway for future studies in the TM field. For this purpose, this study used 16,941 documents collected from Scopus database from 2004 to 2023. Results indicate that the publications on TM have increased over the years, however, the citation impact has declined. Furthermore, the scientific production on TM is concentrated in two countries namely, China and the USA. Our findings showed there are several applications of TM that are understudied, for example, TM for image segmentation and classification. This paper highlighted the future research directions, most importantly, calls for increased multidisciplinary research approaches to fully deploy TM algorithms optimally and thus, increase usage in non-computer science subject areas.

Analysis of Research Data in Information Science Using the Topic Modeling Method
Sompejch Junlabuddee

Journal of Mekong Societies, 2021

Most research data in the modern world are in digital format, and there is therefore a need to develop high-efficiency tools that can provide access to and an understanding of these data. Computerization technology based on natural language processing with a capacity for topic extraction and categorization would enable us to identify new topics and future directions for research in several fields of study. The aim of this research was to analyze and categorize information science research data obtained from journals listed in an international database between 2013 and 2019. The research methodology applied here was data analysis based on the topic modeling method, a technique used to locate word groups or topics from a corpus containing complicated and difficult works. This method yields reliable and high-accuracy outcomes. The data analyzed here were drawn from research articles published in information science journals, the names of which were listed in the Scimago Journal and Country Rank between 2013 and 2019. Only journals in the Web of Science and articles written in English were included. A total of 30,571 research articles obtained from 677 volumes of 99 journals were analyzed using the topic modeling method, and topics were assigned by experts in the field. The findings revealed that over the past seven years, research was carried out on 30 topics in information science. The five most frequently researched topics were competency development, data management, social media analytics, public and community services, and bioinformatics. A comparison with other research data analyzed in the field of information science over the past five years using other techniques showed clear differences and a tendency of the research topics to change. The results of this research can greatly benefit the identification of research directions for the future.

Evaluating the Performance of Topic Modeling Techniques for Bibliometric Analysis Research: An LDA-based Approach
Wirapong Chansanam

HighTech and innovation journal, 2024

Digital technologies have been used for a vast amount of bibliometric analysis research. Although these technologies have made scientific investigation more accessible and efficient, scholars now face the daunting task of sifting through an overwhelming number of documents. This study aims to identify bibliometric research analysis's primary topics, categories, and latent topics from a global perspective. This study utilized topic modeling techniques to analyze the abstracts of 16,039 eligible papers published between 1977 and 2023 in the Scopus database. Through the use of Latent Dirichlet Allocation (LDA) topic modeling, the study was able to identify four distinct research topics and observe how they have evolved over time. The research topic has shifted its focus from individual concepts and words to relationships between nodes and conceptual, intellectual, and social structures. The study's findings have significant implications for bibliometric analysis-related research, providing valuable insights into trends and patterns in bibliometric analysis content within large digital article archives. The LDA has proven to be an efficient tool for analyzing these trends and patterns quickly. This study's novel approach considers factors for word embedding usage and optimal topic numbers. It focuses on a full understanding of the LDA results and combines statistical analysis, domain knowledge, and temporal exploration to better understand how data structures work.

Topic Modeling Analysis of Webometrics, Informetrics, and Scientometrics Research Trends
Sompejch Junlabuddee

Conference Proceeding on The7 th I-LISS International Conference, 2023

This research is a data analytics study using the Topic Modeling method. The data modeling focused on the research trends of webometrics, informetrics, and scientometrics (WIS) published in journals indexed in the Scopus database during the past 10 years (2012-2021). The selection of research articles for analysis was conducted by searching for articles titles, abstracts, and keywords. The search terms used were "webometr* or informetr* or scientometr*". The search results yielded a total of 3,524 articles. Topic modeling approach was conducted which comprised of 3 steps: data layer, Latent Dirichlet allocation (LDA) model layer, and application layer. Findings reveal that (1) WIS research publications-There was a consistent increasing trend in the number of publications each year. Analysis of the article data classified by the country of the authors, show the highest percentage comes from India, followed by China. The top journals that published research articles on WIS were Library Philosophy and Practice, Scientometrics, and Journal of Informetric. (2) WIS research topics-It was found that the model with 10 topics achieved the highest Coherence score. Therefore, the WIS research was grouped into 10 topics: Citation impact-scientometrics; University rankings-webometrics; Scholarly publication's contribution; Health, psychology informetrics; Web user analysis (retrieval, query); Scientific production and development; Research network collaborations; Knowledge analysisscientometrics; Research trends; and Publication performance. And (3) WIS research using topic modeling-There were 530 articles that employed topic modeling which focused on scientometrics, followed by informetrics and webometrics. The WIS research utilizing topic modeling was prevalent in the field of Library and Information Science, as well as in disciplines such as Active Learning, Clinical Medicine, Music Psychology, Life and Natural Sciences, Agricultural Sciences, and Pharmaceutical Effluents. And the popular software and tools used, researchers commonly employed VOS viwer software, CiteSpace, Histcite, Bibexecl, Gephi, SPSS software, STATA software, and Microsoft Excel.

Analysing Library and Information Science Articles Using Topic Modeling Approaches
DEBASIS MAJHI

DESIDOC journal of library and information technology, 2024

Identifying trends in research through co-citation or content analysis of journal contents is quite a common practice in LIS research. In this study, however, we proposed the Latent Dirichlet Allocation (LDA), a popular topic-modeling approach for identifying research trends of published articles in three scopus-indexed Indian LIS journals. A total of 1213 titles & their abstracts published between 2011 and 2022 have been considered. From these data, a corpus of frequently used 15 key phrases was identified from each journal using Count Vectorizer and then ten topics having higher coherence scores were extracted from each journal corpus using LDA techniques to understand to what extent these topics are different in these journals. The analysis of the study indicates that 'Library users' studies' especially in academic libraries; and 'bibliometric indicators for measuring research growth are a few common topics in these journals and, technological innovation; utilisation of electronic and print information resources; library management; or network analysis are some of the topics that are journal specific. From the t-SNE visualisation and pyLDAvis diagram, it was seen that the topics of DJLIT are significantly unique with discrete distributions than the other two journals. On analysing the growth of the top ten topics longitudinally, it was seen that research on digital libraries, analysing the global output, online search strategy, ranking universities, etc. are concurrent interests of research among researchers while academic library resources, including electronic resources and its use, open access are among diminishing research interests of authors. Since the topic-modeling approach can provide results devoid of bias, it can be used to identify research land scape longitudinally as well as obsolescence of topic in a domain.
