Competency Questions(CQs) play an important role in the ontology development lifecycle, as they represent the ontology requirements. Although the main methodologies describe and use CQs, the current practice of ontology engineering makes a superficial use of CQs. One of the main problems that hamper their proper use lies on the lack of tools that assist users to check if CQs are being fulfilled by the ontology being defined, particularly when these ontologies are defined in OWL (Ontology Web Language), under the Description Logic formalism. We propose a mechanism to support evaluating whether the ontology follows their correspondent CQs.

Evaluating Ontologies with Competency Questions.

Global Research Trends of Public Libraries from 1968 to 2017: A Bibliometric and Visualization Analysis

Systematic organization of domain knowledge has many advantages in archiving, sharing and retrieval of information. Ontologies provide a cushion for such practices in the semantic Web environment. This study aims to develop an ontology that can preserve the knowledge base of traditional dance practices.,It is hypothesized that an ontology-based approach for the chosen domain might boost collaborative research prospects in the domain. A systematic methodology was developed for modeling the ontology based on the analytico-synthetic rule of library classification. Protege 5.2 was used as an editor for the ontology using the Web ontology language combined with description logic axioms. Ontology was later implemented in a local GraphDB repository to run queries over it.,The developed ontology on traditional dances (OTD) was tested using the dances of the Rabha tribes of North East India. Rabha tribes are from an indigenous mongoloid community and have a robust presence in Southeast Asian countries, such as Myanmar, Thailand, Bangladesh, Bhutan and Nepal. The result from HermiT reasoner found the presence of no logical inconsistency in the ontology, while the OOPS! pitfall checker tool reported no major internal inconsistency. The induced knowledge base of traditional dances of the Rabha’s in the developed OTD was further validated based on some competency questions.,In the growing trend of globalization, preservation of the cultural knowledge base of human societies is an important issue. Traditional dances reflect a strong base of the cultural heritage of human societies as they are closely related to the lifestyle, habitat, religious practices and festivals of a specific community.,The current study is exclusively designed, keeping in mind the variables of traditional dance domain based on a survey of the user- and domain-specific needs. The ontology finds probable uses in traditional knowledge information systems, lifestyle-based e-commerce sites and e-learning platforms.

Ontology for preserving the knowledge base of traditional dances (OTD)

Nature is a weekly journal of multidisciplinary sciences with a huge range of followers in the scientific community. The purpose of the study is to analyse the citations of the full research articles published in Nature journal from 2006 to 2015. During this period Nature has published 8335 research articles. In the study the weightage of the research articles published in Nature were measured through immediacy index comparison of the research articles to the overall journal. The authorship pattern of the articles were measured and a cited references study was also conducted for measuring the self citations generated by Nature each year,the references per articles present and identifying core cited journals by Nature and their respective subject areas, which libraries in turn may use for collection development policies. Ranking of contributing countries and contributing organizations were also made by % share of article contribution. To check if any kind of biasness is present in Nature publications, a comparative evaluation of top contributing countries has also been made based on Nature Index. Web of Science core collection was used as the data source and Bibexcel bibliometric tool was used for data analysis purpose.

The purpose of this paper is to make a systematic review of the library metadata development history listing out the most significant landmarks and influencing events from Thomas Bodley's rules to the latest BIBFRAME architecture, compare their significance and suitability in the modern-day Web environment.,Four time divisions were identified, namely pre-1900 era, 1900–1950, post-1950 to pre-Web era and post-Web era based on pre-set information available to the authors regarding catalogue rules. Under these four divisions, relevant information sources regarding the purpose of the study were identified; various metadata standards released at different times were consulted.,Library catalogue standards have undergone transitive changes from one form to another primarily influenced by the changing work environment and different forms of resource availability in libraries. Modern-day metadata standards are influenced by the opportunities provided by the World Wide Web towards libraries and work as a suitable base for data organisation at par with Semantic Web standards.,Information organisation processes have gone towards a more data-centric approach than earlier document-centric nature in current Semantic Web environment. Libraries had to make a move in this process, and modern-day guidelines in this regard bring the possibility of large-scale discovery services through curated information resources.,The study discovers relationships between key events in the course of development of metadata standards and provides suggestions and predictions regarding it's future developments.

Searching the great metadata timeline: A review of library metadata standards from linear cataloguing rules to ontology inspired metadata standards

Scimago Journal Rank (SJR) is a size independent measure of journal evaluation where citation coming from quality journals carries more value than citations from ordinary journals and h-index, used as a metrics for author impact when initially introduced, is now a day’s used for journal evaluation in major citation databases like Scopus, Google scholar etc. Both the indicators follow different methods of calculation. SJR is a prestige based measure where the scholarly value of incoming citations matters most than its quantity, while h-index is a quantity based measure where the amount of incoming citations plus the number of published paper both matters. The current study tries to identify how the ranking value of journals changes when compared with the two indicators. The issue was addressed by taking the context of Indian journals indexed in Scopus. Even though the process of calculation for both the indicators is different, it is expected that their ultimate result is same i.e. ranking quality journals at top. The findings of ranking of quality journals represent strikingly different result given by both the indices. The dissimilarity in measure is tested using z-test for two sample means for median difference. Also the biasness of the indicators towards time and subject domains is tested on a raw count.
