The role of social tags in web resource discovery: an evaluation of user-generated keywords

Social tags are user generated metadata and play vital role in Information Retrieval (IR) of web resources. This study is an attempt to determine the similarities between social tags extracted from LibraryThing and Library of Congress Subject Headings (LCSH) for the titles chosen for study by adopting Cosine similarity method. The result shows that social tags and controlled vocabularies are not quite similar due to the free nature of social tags mostly assigned by users whereas controlled vocabularies are attributed by subject experts. In the context of information retrieval and text mining, the Cosine similarity is most commonly adopted method to evaluate the similarity of vectors as it provides an important measurement in terms of degree to know how similar two documents are likely to be in relation to their subject matter. The LibraryThing tags and LCSH are represented in vectors to measure Cosine similarity between them

Wikipedia and LIS: A study of coverage of concepts for UGC-NET

UGC-NET is an eligibility examination for those who are aspiring for the academic jobs in the universities and colleges in India. There are multiple sources, mainly printed publications, available for preparation of UGC-NET exams. The present study examines the suitability of Wikipedia as a source for preparation. The 396 topics culled from the UGC-NET syllabus in LIS was compared for their coverage in Wikipedia. It was found that 55.55% of the topics are available on Wikipedia. The answers to the previous years’ questions were also searched. The study found that 35.48% of answers could be traced in Wikipedia. The Wikipedia was also examined from other parameters such as up-to-datedness, comprehensiveness, illustrations, and references and external links. The analyses show that Wikipedia could be a source for preparation for UGC-NET. The study has an implication for those who are seeking the eligibility for the jobs through UGC-NET

A study of ‘calf-path’ in file naming in institutional repositories in India

This study examined the file naming practices in 39 institutional repositories. There is evidence that calf-path exists infile naming among the curators of institutional repositories in India. The study showed that no standard or logic seems tohave been followed by repositories in the naming of the files, except by the National Digital Library of India (NDLI) and theCSIR-National Institute of Science Communication and Policy Research (CSIR-NIScPR). The study also examined thecomposition of the filenames, which shows that the author names (11.2%), titles (11.9%), journal title with volume and issuenumbers (21.1%) form the basis for the formation of filenames. It is suggested that digital repository managers have to givemore attention to name files in the institutional repository in the interest of uniformity and consistency

Use of MARC21 control field data in University Library OPACs in Karnataka: A study

This study discusses about importance of MARC21 control field and its effective implementation in university libraries OPACs in Karnataka. The catalogue records available through library web OPACs of universities under study formed the data source for this study. The university library web OPACs which we examined in this study have used Koha ILMS. One thousand and eighty-eight (1088) records were randomly selected from the nine university library web OPACs for the study. The study examined the proper implementation of 008 control field of MARC21, which is an important data element in information retrieval. The study found that average length of a cataloguing record was 1572.78 characters. The study as also revealed that libraries web OPACs under study have given scant attention for control fields, 001 and 003 were the two tag numbers that have been used extensively. Overall the university libraries have neglected control fields data element in their OPACs. This adversely affect the data retrieval from the user point of view. The study strongly recommend that libraries should fill up the data required for control fields while cataloguing their records

Insight Into Intellectual Property in Patent Medicine: An Indian Perspective

This paper aims at exploring intellectual property in relation to patent in medicine in India. Knowledge economy is the engine upon which development and creativity depends that has been instrumental in differentiating countries as developed or underdeveloped. India, being a member of World Trade Organization (WTO) has recognized the importance attached with IP thus investing hugely in intellectual advancement thereby reaping the advantages of second world population. Focusing on three key sectors namely, pharmaceutical, biotechnology, and IT sectors, scholars recognized the contributions these sectors offer to the growth domestic products and economic development of the countries. For instance, in India, many companies are continuously contributing to its economic development and growth at exponential rate. Many issues are discussed with regards to intellectual property

Forage potential of sorghum and pearl millet

Sorghum and Pennisetum are two of the gifted genera of the tropical regions that provide food, feed, stover (dry straw) and fuel to millions of poor farmer families and their livestocks. Single-cut sorghum and multi-cut pearl millet varieties are also cultivated for green fodder (forage). In addition, the interspecific sorghum sudangrass annual multi-cut hybrids are grown for green fodder. The interspecific pearl millet × napiergrass hybrids are perennial and yield green fodder throughout the year. Pearl millet uses less water per unit of forage production, tolerates both lower and higher soil pH and higher aluminium concentration, and is rich in minerals as compared to sorghum. However, sorghum has a wider range of adaptability and is more widely grown. Geographical preferences, limited market demand, variable prices, and lack of private industry and institutional research support have led to limited pearl millet forage research and cultivar adoption. Forage quality is paramount to palatability or acceptability and animal intake. Plant morphology, anatomical components, digestibility, protein, mineral, cellulose and lignin contents, and anti-nutritional factors like hydrocyanic acid in sorghum and oxalic acid in pearl millet determine animal performance – milk and meat production. Development of multi-cut annual forage sorghum and pearl millet hybrids rather than varieties could have a catalytic effect on forage yield and quality. Diversification of sorghum seed parents (white-grained rather than the currently used red-grained male steriles) and development of sudangrass pollinators with high sugar content and foliar disease resistance offer good opportunities for the exploitation of full potential of the interspecific hybrids. Crop scientists, chemical technologists, and animal health and nutrition experts have a role to play in good quality forage research and cultivar development. Inter-institutional partnerships could forge strong interlinks for strengthening sorghum and pearl millet forage research and development

A Comparative Study of Subject Headings in University Libraries in Karnataka

Subject cataloguing is considered more intellectually intriguing than descriptive cataloguing. Quality of subject catalogues have been the area of interest for researchers. The present study attempted to analyse the subject catalogue records from four university libraries in Karnataka. The result showed that the subject access to the holdings of the university libraries need to be improved. Subject cataloguers have to pay immediate attention in improving the subject access

Citation analysis of SRR's works: A look through the window of Google scholar

This paper presents the findings of a citation analysis study, the impact of S.R. Ranganathan's (SRR's) seminal works, namely, Five laws of library science, Prolegomena to library classification, and Colon classification. More specifically the objective was to quantify the impact of SRR's works through citation analysis, and to study the citation pattern to SRR's works. Google Scholar (GS) was the major data source for the study. We searched the GS during the first week of December 2008 SRR was a prolific writer with over 50 books and over 1000 articles) GS's 894 citations, of which more than half (54.8%) is accounted for by the three books of SRR just mentioned. Presents ranked list of authors citing SRR's three works, their affiliation the periodicals in which these authors have published and related statistic

Indian author productivity in international journals in library and information science: A study

This article is a study of Indian authors? contribution in foreign journals in library and information science during 1970?2005. The data were collected from 18 foreign journals. It is found from the study that 303 articles were published in various foreign journals in the field of library and information science. Scientometrics found to be the preferred foreign journal for Indian authors. Almost 44% of the articles published by them were reported in Scientometrics. While going through the Indian contribution in 18 international journals during the span of 36 years, it was found that only three authors have contributed more than 20 articles. This situation calls more attention from Indian authors to increase their level of productivity in foreign periodicals. The sigh of relief is that during present decade 131 articles (43.23%) have already been published showing that the trend of publishing in foreign journals is increasing
