Comparative Study between Words in Titles and Keywords of Some Articles on Knowledge Organisation

This paper has presented research trends in the area of knowledge organisation since 2002 to 2011. In all, the bibliographic details of 285 research articles on some thrust research areas of knowledge organisation as represented by three keywords, viz., classification and indexing, faceted classification and folksonomy, have been collected from Emerald E-journal Consortia hosted by UGC-INFONET and analysed to study the research trend. The growth of literature in this area shows a logistic pattern over the said span. The distribution of articles over journals has been studied and Journal of Documentation ranked top followed by Aslib Proceedings, The Electronic Library and Library Hi Tech for three specific subject areas consecutively. The frequencies of assigned keywords have been analysed and core keywords have been identified. The words in titles of 285 articles have been analysed and compared with the words in assigned keywords. Two indicators have been defined, viz., Matching Coefficient (MC) and Title-to-Keyword Ratio (TKR) to study the state of matching between these two types of word clusters after comparative study. There are so many MC as found for different articles ranging from 0 to 0.5. The MCs have been graded in a scale set according to their numerical values. In all, seven grades have been set to study the state of matching between two types of words. In general, percentage of bad matching outnumbers the good matching. As titles are assumed as a most concise abstract of an article, it is customary to assume words in title as true reflector of central theme of the same. If words in assigned keywords poorly match the same in titles, then it may be logically inferred that keywords are incorrectly assigned for majority articles
