A Case Study of Utilising Concept Knowledge in a Topic Specific Document Collection
Shaw, G. and Nayak, R.
The use of ‘topic’ concepts has shown improved search
performance, given a query, by bringing together relevant
documents which use different terms to describe a higher
level concept. In this paper, we propose a method for
discovering and utilizing concepts in indexing and search
for a domain specific document collection being utilized
in industry. This approach differs from others in that we
only collect focused concepts to build the concept space
and that instead of turning a user’s query into a concept
based query, we experiment with different techniques of
combining the original query with a concept query. We
apply the proposed approach to a real-world document
collection and the results show that in this scenario the
use of concept knowledge at index and search can
improve the relevancy of results.
