Hello, We have implemented a research module for lucene using BM25 and our structured version of BM25 as ranking functions and a couple of state-of-art query expansion algoritms.
This implementation is quite different to other query expansion modules for Lucene that are available in the web. We have used this implementation in CLEF 2008 Robust WSD track http://ixa2.si.ehu.es/clirwsd/ with very good results. The code and other technical and scientific details can be accessed here: http://grasia.fdi.ucm.es/jose/query-expansion This is an alpha0.0.never.used.before.by.anyone version, we will work on it in the following months to make it easier to use. Please do not hesitate to send comments, questions and/or complaints to the authors. jose -- José Ramón Pérez Agüera Dept. de Ingeniería del Software e Inteligencia Artificial Despacho 411 tlf. 913947599 Facultad de Informática Universidad Complutense de Madrid --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
