Abstract

Query expansion is the process of adding additional relevant terms to the original queries to improve the performance of information retrieval systems. However, previous studies showed that automatic query expansion using WordNet do not lead to an improvement in the performance. One of the main challenges of query expansion is the selection of appropriate terms. In this paper, the authors review this problem using Arabic WordNet and Association Rules within the context of Arabic Language. The results obtained confirmed that with an appropriate selection method, the authors are able to exploit Arabic WordNet to improve the retrieval performance. Their empirical results on a sub-corpus from the Xinhua collection showed that their automatic selection method has achieved a significant performance improvement in terms of MAP and recall and a better precision with the first top retrieved documents.

Various methods and techniques have been proposed or used for AQE and these have been extensively studied in IR. Query expansion is the process of adding additional terms to the original query to improve the IR systems’ performance. AQE is not new; in fact, it has been mentioned in earlier 1960 but has not reached maturity until very recently (Carpineto & Romano, 2012).
