Evaluating the Effectiveness of Axiomatic Approaches in Web Track

In this paper we describe our efforts for TREC 2013 Web track. We focus on evaluating the effectiveness of axiomatic retrieval model on large data collection. Axiomatic approach basically searches for the retrieval functions that satisfy some reasonable retrieval constraints. We also evaluate the semantic term matching method which does the query expansion by choosing the semantically related terms. Experiment results on adhoc task and diversity task demonstrate the effectiveness of the method.
