Abstract:
Bibliography databases provide wide range of information which can be utilized in conducting various kind of analyses like tracking research trends, identifying researchers excelling in a particular subject area, identifying areas where research strength of countries or universities lie or discovering from where a country is receiving its maximum
citations in a particular subject area. Procuring a relevant set of documents
for conducting such analyses is a key factor for their accuracy. Bibliography database resources like Scopus use journal mapping for organizing resources in the database. For this, journals, conference proceedings or articles in such databases are mapped to some predefined structured hierarchy of disciplines and sub-disciplines. However this kind of retrieval is suitable if publications can clearly be distinguished to belong to a particular discipline. The approach breaks down if we would like to analyze activity in interdisciplinary fields. One solution is to use keyword based retrieval. For example, procuring documents belonging to interdisciplinary subject categories like sustainable
development or biotechnology is possible using sets of keywords defining these areas. This study is thus mainly focused on generating sets of keywords which can define even highly focused niche areas. A system is developed using Java as programming platform and the Scopus database for procuring bibliography information. Formal evaluation has been conducted by domain experts.
