cec 2010: good query expansion terms classifier

Filed under: Applications, Congreso, Genetic Algorithms — Tags: — lurdesaraujo @ 5:54 pm

This is the presentation of another world congress on computational intelligence paper: Training a Classifier for Good Query Expansion Terms with a Genetic Algorithm. This is about automatically finding good terms to improve the queries the users submit to the search systems, and this is the presentation: .
We have developed a classifier which has been trained for distinguishing good expansion terms. The identification of good terms to train the classifier has been achieved with a genetic algorithm whose fitness
function is based on users’ relevance judgements on a set of documents. Results show that the training performed by the genetic algorithm is able to improve the quality of the query expansion results.
The paper is not available yet at IEEEExplore, but we can email to whoever is interested.
