基于Lucene的BM25排序函数和查询子句的扩展查询扩展模块。

资 源 简 介

We have implemented the state of the art query expansion techniques combined with a new family of ranking functions which can take into account some semantic structure in the query. This code has been implemented by José Ramón Pérez Agüera and Hugo Zaragoza This implementation is only for research and experimental projects. If you are looking for a robust BM25 implementation for Lucene, we recommend you the project leaded by Joaquin Perez-Iglesias, which had been the reference for our Lucene-BM25 implementation. http://nlp.uned.es/~jperezi/Lucene-BM25/ If you are interested in this work, you can find a scientific description of our approach in: Jose R. Perez-Aguera, Hugo Zaragoza, Lourdes Araujo. Exploiting morphological query structure using Genetic Optimization. NLDB 2008 13th International Conference on Applications of Natural Language to Information Systems. Proceedings will be published in Lecture Notes in Computer Science (LNCS) Springer Verlag. <
