    Structure and Functions of Metasearch Engines: An Evaluative Study
    (Defense Scientific Information and Documentation Centre, 2023-08-03T00:00:00) Bhardwaj, Raj Kumar; Kumar, Ritesh; Nazim, Mohammad
    The present study systematically examines the structure and functions of metasearch engines (MSEs) viz. Dogpile, Metacrawler, DuckDuckGo and Startpage. Further, it identifies the features and services of four metasearch engines and compares them. A checklist method was used to evaluate the four metasearch engines.These check spots are prepared regarding features and services of metasearch engines. The data were collected between April 1 to June 14, 2021, spending two hours daily. Initially, the data was recorded after accessing each MSE, and later,the data was transferred to MS Excel. The study ascertained that out of 101 check spots, Dogpile scored (66) points, Metacrawler (63), DuckDuckGo (71), and Startpage (59). DuckDuckGo is ranked first among all the four metasearch engines with 70.3 %, followed by Dogpile, Metacrawler, and Startpage respectively. A checklist used in the study contains only 101 check spots to compare the metasearch engines. Further, users� perception regarding the four metasearch engines is also not covered in the present study. The present study is the first of its kind, which compares four popular metasearch engines using a checklist method. The outcomes of the study shall help research scholars, librarians, information scientists, faculty members, and common masses choose the appropriate metasearch engine. Further, the study shall also help the developers of e-resources in incorporating more features so that users can benefit. � 2023, Defense Scientific Information and Documentation Centre.

    Research Online Visibility of LIS Faculties at Central Universities in North India: An Analysis of Google Scholar
    (Defense Scientific Information and Documentation Centre, 2023-01-06T00:00:00) Lohia, Pragya; Prakash, Hari
    The study examines the Google Scholar profile of LIS faculties employed in central universities of North India to determine their research online visibility. Data was obtained by doing manual searches on Google scholar on 4 July 2022 with the appropriate name of the faculties and their affiliation. The study found that 74 % of the faculty have a Google Scholar profile. Findings show that Prof. Margam Madhusudhan (DU) is leading among the faculties with a citation count of 1715, the highest number of publications, 162, and the highest i10 index of 31. Further, Prof. Bhaskar Mukherjee (BHU) and Prof. Margam Madhusudhan (DU) have the highest-ranked h-index, with 18 each leading the list. The authors advocate that a GS profile can be used to assess the research productivity of the faculty and that the authors� work is more accessible if they create a Google Scholar profile for personal and institutional ranking purposes. The study also recommends displaying thrust areas for faculty members to boost the visibility of their areas of interest, which can be used for collaboration by other faculties or researchers with similar interests in India and overseas. � 2022, DESIDOC.

    Information system for visually impaired in Indian universities: a user�s perspectives
    (Emerald Group Holdings Ltd., 2021-10-10T00:00:00) Bhardwaj, Raj Kumar
    Purpose: This study aims to comprehend the perceptions of visually impaired users in development of information systems in Indian universities. This will help higher educational institutions in India to fulfil information requirements of visually impaired users. Design/methodology/approach: A twofold method was used in the study: survey of visually impaired students in four universities; design and development of an online information system for visually impaired (ISVI). A structured questionnaire was used for survey of visually impaired users in Indian universities. The questionnaire with 33 open-ended questions was distributed among 603 visually impaired users and 316 responses were received. Stratified sampling technique was used in data collection. Response rate was 52.4%. The received responses were analysed using Statistical Package for Social Sciences version 19 and presented through tables and figures. Findings: Majority of respondents revealed that lack of content availability in vernacular language, poor information resources access mechanism, less volume of course content and poor maintenance of assistive software(s) and devices and non-standardized e-resources compatible with the assistive software(s) are some major inhibits faced. Majority of respondents revealed that they prefer scribes in examinations because use of assistive technology (AT) is time-consuming. Lack of training and confidence in using AT is another reason for preferring scribes in examinations. Research limitations/implications: This study was conducted on a limited number of visually impaired uses in Indian universities. Also, the online system ISVI contains a sample collection related to undergraduate courses only. Practical implications: This study will help Indian universities to identify problems faced by visually impaired users. Findings of the study can help faculty members, decision-makers to understand the perspective of visually impaired. Besides this, the study can also help government agencies in formulating policies. Findings will help in developing robust information resources suiting the needs of visually impaired. Originality/value: This study developed an online system ISVI (www.isvi.in) suitable to address the requirements of visually impaired students. Furthermore, it can guide policymakers, faculty members and information professionals in developing seamless open access information systems. � 2021, Emerald Publishing Limited.

    Altmetrics and their relationship with citation counts: a case of journal articles in physics
    (Emerald Publishing, 2022-01-13T00:00:00) Shrivastava, Rishabh; Mahajan, Preeti
    Purpose: The first purpose of the present study is to investigate the coverage of journal articles in Physics in various sources of altmetrics. Secondly, the study investigates the relationship between altmetrics and citations. Finally, the study also investigates whether the relationship between citations and altmetrics was stronger or weaker for those articles that had been mentioned at least once in the sources of altmetrics. Design/methodology/approach: The journal articles in Physics having at least one author from an Indian Institution and published during 2014�2018 in sources of altmetrics have been investigated. Altmetric.com was used for collecting altmetrics data. Spearman�s rank correlation coefficient (?) has been used as the data found to be skewed. Findings: The highest coverage was found on Twitter (22.68%), followed by Facebook (3.62%) and blogs (2.18%). The coverage in the rest of the sources was less than 1%. The average Twitter mentions for journal articles tweeted at least once was found to be 4 (3.99) and for Facebook mentions, it was found to be 1.48. Correlations between Twitter mentions�citations and Facebook mentions�citation were found to be statistically significant but low to weak positive. Research limitations/implications: The study concludes that due to the low coverage of journal articles, altmetrics should be used cautiously for research evaluation keeping in mind the disciplinary differences. The study also suggests that altmetrics can function as complementary to citation-based metrics. Originality/value: The study is one of the first large scale altmetrics studies dealing with research in Physics. Also, Indian research has not been attended to in the altmetrics literature and the present study shall fill that void. � 2022, Emerald Publishing Limited.

    Availability and preferences for information services to visually impaired tertiary students in Delhi
    (Emerald Group Holdings Ltd., 2021-10-04T00:00:00) Bhardwaj, Raj Kumar
    Purpose: The study aims to understand the information services provided to visually impaired users in Indian universities. Further, the study identifies the nuances of information system for visually impaired (ISVI) development suitable to the requirements of the visually impaired community in Indian higher educational institutions. Design/methodology/approach: A two-fold methodology was followed in the study: (1) empirical survey and (2) information system design and development. The empirical survey was conducted in Indian higher educational institutions wherein 316 responses were collected including 185 (58.5%) undergraduate and 131 (41.5%) postgraduate students. A stratified random sampling technique was used in data collection. Empirical study findings were further used as a basis for ISVI design and development for addressing the information requirements of visually impaired users. Findings: The study found that 232 respondents (73.2%) access the Internet every day. �Surprisingly, 143 respondents (45.3%) revealed that no digital infrastructure is available in their institutions, while 173 respondents (54.7%) stated digital infrastructure is available. A total of 210 respondents (75.9%) highlighted that the interface of open access (OA) resources is not designed as per visually impaired (VI) students' requirements. information and communication technology (ICT) infrastructure is not up to the mark revealed as by 34 respondents (10.7 percent) and was rated �poor.�� A total of 268 respondents (90.2%) expressed that their institution should develop the information system to full their information needs. Research limitations/implications: The study is conducted in only one state in India due to financial hindrances. Visually impaired students studying in other states of India are not covered in the study, which may have different perception about the design and development of information system for the visually impaired. Practical implications: An online ISVI is designed and developed under the study, which is accessible at http://www.isvi.in. Furthermore, the findings of the study may also be used by administrators of the higher educational institutions for building ICT infrastructure for visually impaired students. Originality/value: No study has been conducted in Indian higher educational institutions for understanding the availability and preferences of information services to visually impaired tertiary students. � 2021, Emerald Publishing Limited.
