Assessing the Effectiveness of LSI in Approaching the Intention of a User’s Query

Massoud Moussavi, The World Bank, USA and Robert Najlis, Indiana University, USA

Documents retrieved in response to a user’s query should reflect the intention of the user. Keyword searches are not sufficient to accomplish this task. This paper considers Latent Semantic Indexing (LSI) as a possible solution. LSI is considered in the context of a large set of World Bank documents. LSI is shown to be useful in this regard, but not a complete solution. Additional, domain specific, information would be needed as well.
