This part of the study highlights the contents of the published articles in terms of various disciplines or sub-disciplines and the bibliometric aspects discussed in these articles. The analysis of 902 papers published by Indian scholars during1995-2014 indicates that the main focus of bibliometrics/scientometrics is on assessment of science and technology in India in different sub-disciplines including contributions by Indian states and other individual countries followed by bibliometric analysis of individual journals. Papers dealing with bibliometric laws received a low priority as compared to other subdisciplines of bibliometrics/scientometrics. The analysis of data indicates that the share of theoretical studies using mathematical and statistical techniques which were missing in the earlier period (1970-1994) has increased during 1995-2014. The field of medicine as a discipline received the highest attention as compared to other disciplines.

The Literature of American Library History, 2014–2015

The paper examines 25,132 biochemistry research contributions of Indian scientists covered in the Web of Science for a period of 10 years (2004-2013). It was found that the biochemistry research is gradually growing and average annual growth rate was 36.84 per cent. The solo research was not prevalent and team research is more in the Indian biochemistry research and 97.46 per cent publications were contributed by multi- authors. It was observed that the value of co- authorship index was generally increasing and it varied from 93 to 105 during the period of study. Journal articles contribute 89.43 per cent of the total output followed by reviews (7.14 %). Indian researchers collaborate largely with the researchers of USA (2.49 %). The geographical distribution shows that Tamil Nadu, Uttar Pradesh and Delhi lead the list. The study shows that, C. Abdul Jaleel (58) and L. Pai (37) are the top ranked authors in the field. ‘Plos One’ is the top ranked journal and it published 296 papers during the study period. Academic institutions contribute more number of papers (50.26 %) followed by research institutions (28.24 %). The Lotka’s law was not found fit with the observed author productivity distribution of Indian biochemistry research.

Scientometric Profile of Biochemistry Research in India a Study Based on Web of Science

Social tagging allows users to assign any free-form keywords as tags to any digital resources through a decentralised way. Many information scientists find that there are similarities through their studies between usergenerated social tags and the librarian-generated subject headings for the libraries. The present study was conducted to identify the similarity and dissimilarity between user-generated social tags and librarian-generated subject terms of 1000 books in the domain of History. The study also conducted to identify whether social tags can replace controlled vocabularies. The study finds that only a small portion of terms overlaps with each other (3.54 % of social tags & 56.07 % of SLSH terms) and Spearman’s rank correlation proves that there is a good association between overlapping terms. Jaccard similarity coefficient highlights that users and the librarian use different terminologies (as J = 0.13, 0.12 & 0.11). Individual title wise comparison also defines that 90 per cent (88.4 %) of all book titles where users and the librarian use at least one common term. Users use the least subject & non-subject terms but use some personal tags for personal benefit whereas the librarian use only subject & non-subject terms. Matching with each book title clarifies that for describing resources users mostly use title based keywords (696) whereas the librarian use very little title based keywords (113). The study clearly defines that social tags can enhance the experience of library users. If it can be exploited properly it can complement to controlled vocabularies but can not replace the controlled vocabularies used for libraries a long time. Overall the study explicitly identifies the viability regarding the adoption of social tags into the library databases where the resources in the field of history will be accessed.

Duplicate bibliographic record detection with an OCR-converted source of information

This paper presents a methodology for automatic identification of bibliographic data elements from the title pages of books. Also enumerates the various steps like scanning the title pages, running optical character recognition (OCR) software, generating HTML files out of title pages and applying heuristics to identify the bibliographic data elements. Much of the paper deals with the surveys undertaken to analyze the characteristics of various bibliographic descriptive elements like title, author, publisher and other elements. The first survey deals with the sequence of the bibliographic data in the title pages. The second survey deals with the font size, font type and the proximity of each bibliographic element on the title pages. The survey results are then used to develop heuristics, in order to develop a rule‐based expert system which can identify the bibliographic elements on the title pages. The results of the system are presented, along with problems encountered.

Heuristics for identification of bibliographic elements from title pages

This paper presents a methodology to capture bibliographic data from the verso of the title pages of documents. A survey has been undertaken to identify the syntactic and semantic features of bibliographic elements on the verso of title pages. These features include the font size, line numbers and appearence of certain string of characters. Emphasis is given to the study of “cataloguing‐in‐publication” data. The results of the survey are used to develop heuristics which can help in developing a program to automatically identify the various bibliogaphic data elements. The back of the title pages are scanned and stored as HTML pages using optical recognition software. The heuristics are then applied on the HTML pages. Few samples of input and the output generated are presented. Finally, the problems related to OCR and the heuristics are enumerated.

This paper reports on a scientometric study of 834 articles on Carbon nanotube research in India spanning over the years 1999 to 2012 downloaded from Web of Science. The study analyses literature growth trends, which shows an initiation of potential growth of research in this subject since 2008. It also examines collaborations with different countries. The authorship pattern, document types involved and active Indian institutions co-coordinating research in this subject have also been studied. Bradford law of scattering was applied to identify the core journals and Lotka's law to study the authors productivity pattern.

\n \n \nThe concept of ‘social tagging’ has gained popularity nowadays due to the emergence of web 2.0 technologies. Those technologies led to the practice of associating metadata with digital resources among users through collaboratively or socially for self-information retrieval. Many researchers have opined that social tags can enhance the use of library collections. The present study was predominantly carried out to compare social tags collected from the LibraryThing website with Library of Congress Subject Heading (LCSH) descriptors collected from the Library of Congress Online Catalogue applied for thousand book titles in the field of Economics. The study also aimed to know whether social tags can be applied in the library database or not. The findings elucidate that users mostly use descriptors (47.39 %) as tags than expert’s usage of tags (12.77 %) as descriptors. Spearman’s correlation suggests that 75 per cent chance where tags and descriptors can be used simultaneously in overlapping terms. The Jaccard similarity coefficient identifies that users and experts use different terminologies to annotate the books. Users and experts use at least one common keyword for major book titles (908). Users mostly sought title based keywords but experts use mostly subject-based terminologies. The study further clarifies that social tags may be incorporated into the library databases but cannot replace LCSHs. The accessibility and usage of documents especially in the field of economics may be enhanced once the notion of social tags is incorporated with the library OPAC. \n \n \n

Social Tags Versus LCSH Descriptors a Comparative Metadata Analysis in the Field of Economics

In developing countries like India, taxpayers’ money is utilized for research and development. The researchers conduct their research using public money and publish their research papers in commercial journals. Firstly, the researcher uses Government funds for research. Secondly, government funds are also spent on subscribing to high-cost journals. Also, many Indian academic institutions can not subscribe to reputed commercial journals due to a lack of funds. In other words, research output generated using public money is not accessible to all. OA journals can solve this problem smoothly. In this study, researchers analyze the trends in Open Access publications and Closed access publications by India's top research institutes, IITs. Researchers found that IIT Hyderabad (26%) published the highest number of open-access publications. Old established IITs' open-access publication figures are lower than newly set-up IITs. However, there is an increase in Open Access publications by IITs over the last decade.
