To date, library professionals’ knowledge of text mining tools and practice is mainly limited, resultantly, the library community poorly understands the full range of issues related to text mining. This article provides information on applying a text mining approach called topic modelling in the library and information science domain. Topic modelling is a text mining approach that determines a generative model for documents. This article maps how topic modelling can be used in libraries through various databases during 2009–22 period. It was found that the gap between information users and librarians can be bridged by text mining training. The study concludes that librarians must develop text mining skills to meet their patrons’ needs.

Thus, the present study forwards a solution to the above problem by applying topic mining and prediction modeling tools to 263 ETDs submitted to the PQDT Global database during 2016-18 in the field of library science. This study was divided into two phases. The first phase determined the core topics from the ETDs using Topic-Modeling-Tool (TMT), which was based on latent dirichlet allocation (LDA), whereas the second phase employed prediction analysis using RapidMiner platform to annotate the future research articles on the basis of the modeled topics. The core topics (tags) for the studied period were found to be book history, school librarian, public library, communicative ecology, and informatics followed by text network and trend analysis on the high probability co-occurred words. Lastly, a prediction model using Support Vector Machine (SVM) classifier was created in order to accurately predict the placement of future ETDs going to be submitted to PQDT Global under the five modeled topics (a to e). The tested dataset against the trained data set for the predictive performed perfectly.

To tackle the same, topic modeling was first applied to Library and Information Science (LIS) theses submitted to Shodhganga (an Indian ETDs digital repository) to determine the five core topics/tags and then the performance of the built model based on those topics/tags were analyzed. Using a Latent Dirichlet Allocation based Topic-Modeling-Toolkit, the five core topics were found to be information literacy, user studies, scientometrics, library resources and library services for the epoch 2013-2017 and consequently all the theses were summarized with the presence of their respective topic proportion for the tags/topics. A Support Vector Machine (Linear) prediction model using RapidMiner toolbox was created and showed 88.78% accuracy with 0.85 kappa value.

It describes the importance and usage of topic mining for researchers and librarians. An experiment study is also covered which applies topic modeling in a real scenario, where five model topics for the articles published in DESIDOC Journal of Library and Information Technology for the year 2017 using Topic-Modeling-Toolkit and prediction modeling is constructed using RapidMiner toolbox.

Dueling COVID-19 misinformation: Perceptions and behavior of the rural population from South Asian countries

The survey questionnaire was distributed to a convenient sample of 400 respondents from the three most populated SA countries selected due to their shared socio-cultural history; limited by fund availability and travel restrictions due to the prevailing lockdowns during the data collection period of early 2022. Results indicate that 92.98% of the participants perceived the presence of COVID-19 misinformation to varying degrees around them with less than 10% finding it easy to verify the accuracy of the information. The results indicate that the participants initially believed the made-up news and information to be true and then experienced fear or uncertainty upon realizing that it was fake. Results further show significant differences in perception and behavior when analyzed with the parameters of gender, age, education, and religion. Our study highlighted that female respondents perceived less than male respondents that fake news was around them, and younger participants of the study had less perception of the presence of fake news around them. The present study also found that the education level of respondents is a strong predictor of their perception of COVID-19 misinformation. Respondents with high school degrees perceived less made-up news and information than associate and master-level degree holders. The findings indicate a lack of media literacy, with a vast majority of individuals being susceptible to false information. The findings of the study will help healthcare professionals, information professionals, social workers, extension workers, and policymakers to deal with the Infodemic and further also assist in designing shared health information literacy programs across the region.

The purpose is to analyze the use of technology to promote collaborations and networking within online professional settings. Design/methodology/approach: In this case study, the authors particularly examine the initiatives as they contribute to the organization, which allows us to understand the interactions between information technology-related tools and online communication. Findings: Successful engagement in informal gatherings was initiated through the planning and implementation with a focus on the following: thematic meetings, time management and participation. Originality/value: The case study presents an analysis of the use of technology integration into the planning processes that were undertaken by a group of members to enhance informal gatherings for relationship building within a global community of members during the COVID-19 pandemic. The authors suggest ways of engaging users that could be used as a model for organizations alike.

Historically, the general lack of statistical expertise and programming skills has stopped many with humanities or social sciences backgrounds from performing and fully benefiting from such analyses. Thus, we introduce Coconut Libtool (www.coconut-libtool.com/), an open-source, web-based application that utilizes state-of-the-art natural language processing (NLP) technologies. Coconut Libtool analyzes text data from customized files and bibliographic databases such as Web of Science, Scopus, and Lens. Users can verify which functions can be performed with the data they have. Coconut Libtool deploys multiple algorithmic NLP techniques at the backend, including topic modeling (LDA, Biterm, and BERTopic algorithms), network graph visualization, keyword lemmatization, and sunburst visualization. Coconut Libtool is the people-first web application designed to be used by professionals, researchers, and students in the information sciences, digital humanities, and computational social sciences domains to promote transparency, reproducibility, accessibility, reciprocity, and responsibility in research practices.

The methodology involves retrieving electronic theses and dissertations (ETDs) for LIS discipline from the ProQuest Dissertations and Theses Global database and manually reviewing the full-text ETDs for OCR problems associated with the conversion of PDF files into plain text format. The study examines the factors that impact the quality of OCR output, including the quality of the original document. The findings show that five major types of scanning problems in PDFs were identified that caused OCR errors like joining of words, misspellings, space between words, insertion of random characters, hyphenation, and formatting. To avoid these errors, it is important to use high-quality scanned documents published from the 1920s to the 1970s. Further research could focus on improving the accuracy of OCR technology for large-text documents published before the 1980s.

It is urgent to sort out important, effective, and meaningful information from large databases to guide scientific research and promote the proper control , prevention, diagnosis, and treatment of COVID-19. Thus, this paper presents an experimental study that shows the application of topic modeling, and data visualization for COVID-19 research from 2010 to 2021 for the All India Institute of Medical Sciences (AIIMS), New Delhi, India. The results unveil the focus of scientific research, thereby giving deep insights into how the Indian medical society contributes to combating the COVID-19 pandemic.
