Using Missing Documents in Metasearch Aggregation: An Application of OWA Operator
Hamid Sadeghi · 2009
Aggregation of multiple search engines results is an important issue of a metasearch engine. This paper shows that missing documents, those existing in some of the search engines lists but not in the all lists, play an important role in the result aggregation of different search engines. Furthermore, the paper proposes a new approach for dealing with missing documents using OWA operator weights.
