    Exploring dimensions of metadata quality assessment: a scoping review /
    (SAGE Publications, 2024-03-24) Chandrappa
    Assessing metadata is of paramount importance for several critical reasons. Metadata plays a pivotal role in various aspects, including data retrieval and search, data organization, interoperability, data preservation, and the overall user experience. The purpose of this scoping review is to identify the most commonly measured dimensions of metadata quality in existing studies on metadata quality assessment. The study also investigates the types of data sources and countries contributing most to the literature on metadata quality assessment and the types of documents used to communicate their findings. The methodology involves the application of PRISMA model for qualitatively evaluating 55 studies on metadata quality assessment. The co-occurrence analysis is made on the title and abstract of selected articles using VOSviewer 1.6.18 version, visualization software. The review found that completeness, accuracy, consistency, accessibility, conformance, provenance, and timeliness are commonly used dimensions in metadata quality assessment. However, there is no consensus on their exact definition and measurement, indicating a need for further investigation into less commonly assessed quality dimensions. Digital repositories and open government data are the most commonly studied data sources, with the United States being the leading contributor and journal articles being the most commonly used document type. The cluster analysis based on co-occurrence of terms in title and abstract found three research areas, “Metadata Quality Assessment,” “Metadata Quality Dimensions,” and “Metadata Quality Applications, Frameworks, and Approaches” as prominent areas of research. The originality of the study lies in its methodology that involves rigorous screening of articles on metadata quality. It is a first attempt to qualitatively synthesize literature on metadata quality. The article emphasizes the importance of metadata quality research and the need to improve the flexibility of metadata quality assessment tools to facilitate better metadata quality assurance measures.

    Indian covid-19 preprints submissions in biorxiv and medrxiv preprint servers /
    (medRxiv, 2023-02-16) Chandrappa
    This research aimed at determining the growth of deposition of preprints on servers by Indian researchers during COVID-19 pandemic. In the pre-pandemic period, the dominant server was arXiv upon which research from physics and other related domains have been the most predominant depositors. When the pandemic erupted and the need to share research findings became imperative, many previously dormant preprint servers received vibrant activations from several scientists across the globe. This is with the intention of bridging the gap between delays inherent in reviewing process and the dire need to share information for finding everlasting solutions to the raging pandemic. Many researchers, institutions, countries, etc. have contributed in this regard. The study used quantitative method and iSearch Portfolio expert-curated source for publications and preprints related to either COVID-19 or the novel coronavirus SARS-CoV-2 developed and maintained by National Institute of Health (NIH), US iSearch COVID-19 Portfolio. The study examined the Indian COVID-19 preprints deposited in bioRxiv and medRxiv preprint servers. The findings indicated that, Indian researchers have posted their papers in large numbers in bioRxiv and medRxiv servers with the medRxiv having the highest preprints (417, 40.44%) in 2020 against its counterpart bioRxiv (118, 10.96%) in the same year. Similarly, infectious diseases (except HIV/AIDS) (311) had the highest recurrence of the preprints submitted for deposition in servers. This is followed by epidemiology (263), public and global health (122), bioinformatics (59), among others. There is high collaboration among researchers who deposited their preprints in these servers where about 257 (24.93%) preprints were co-authored by 11+ authors followed by 3-authored and 4-authored with 124 preprints respectively (together accounts for 24.06%) and 2-authroed (114 (11.04%) preprints) respectively in a diminishing manner. The study concluded that, Indian researchers are actively participating in depositing preprints in servers notably bioRxiv and medRxiv.

    The role of libraries and librarians in accreditation and institutional ranking: a case study of indian maritime university library /
    (Elsevier, 2023-01-01) Chandrappa
    Higher education is increasingly becoming a global business. The main factor to distinguish between different universities in university ranking. There are numerous university ranking systems that include a number of citations as one of the measuring indicators. The rest of the journey is dependent on disseminating the publications via proper utilization of the “Research Tools”. Proper tools allow the researchers to increase their research impact and visibility. This study provides information about various activities such as learning management system, NPTEL, IRINS, Google Scholar Profile, ResearchGate, Web of Science, Shodh-Chakra, Digital Repository, e-Library Platform, Plagiarism tools and their adaptations in the Indian Maritime University, Chennai. Academic libraries play a key role in accelerating an institution's academic output and are underrepresented by many accreditation/ranking frameworks. This study aims to educate LIS professionals in preparing for the accreditation and ranking process.

    Methodological approach to assess the library catalogues /
    (Informatics Publishing Limited & Legends Consulting Pvt. Ltd, 2021-01-01) Chandrappa
    The study focused on assessing the quality of catalogue records of university libraries in Karnataka available through their Web OPACs. The study assessed the various parameters of cataloguing records which determines the quality of the records. This study explains the methodology adopted for this research work in detail. The methodology gives describes the design of the study and procedures, the universities and sample records, instruments, methods of data collection, and treatment of data. The researcher identified nine of the existing 44 universities of Karnataka for the collection of data for the study. Only nine universities provided access to their catalogue records via the internet-based OPACs and hence, they have been selected.

    Next Generation of Catalogues:A Comparative Analysis of Opacs of University Libraries in India /
    (Informatics publishing limited and legends consulting pvt. ltd., 2017-01-01) Chandrappa
    The Next Generation Online Public Access Catalogue (OPAC), generally termed as OPAC 2.0, is the results of continuous rethinking and reworking to make the information retrieval more effective, efficient and elegant with improved searching experiences. This paper attempts to list the OPAC functionalities by studying the OPAC 2.0 features available in representatives of all three types of software – commercial, open source and free. This paper attempts to compare the features available in the OPAC of ten universities against the listed expectations. Effort is also made to understand the level of OPAC 2.0 in the software adopted by these universities for integration of e-Resources, and interoperability standards.
