Abstract:
Query expansion (QE) is a potentially useful technique to help searchers formulate improved query
statements, and ultimately retrieve better search results. The objective of our query expansion technique is to find
a suitable additional term. Two query expansion methods are applied in sequence to reformulate the query.
Experiments on test collections show that the retrieval effectiveness is considerably higher when the query
expansion technique is applied.
