Evaluating Word Sense Disambiguation Tools for Information Retrieval Taskrder to apply an state-of-art WSD tool? In addition, we have evaluated several approaches in order to apply WSD. We have used several types of indices. Thus, we have generated 13 indices and we have carried out 39 different experiments, obtaining that some indices based on WSD tools even outperforms

IXA at CLEF 2008 Robust-WSD Task: Using Word Sense Disambiguation for (Cross Lingual) Information Re. We tried several query and document expansion and translation strategies, with and without the use of the word sense disambiguation results provided by the organizers. All expansions and translations were done using the English and Spanish wordnets as provided by the organizers and no other resour

The evaluation was performed using SENSE (SEmantic N-levels Search Engine), a semantic search engine that tries to overcome the limitations of the ranked keyword approach by introducing ., which integrate (and not simply replace) the lexical level represented by keywords..We sho

Furthermore, we have experimented with two well known relevance feedback methods - LCA and PRF -, in order to figure out which is more suitable to take profit of the WSD query expansion based on Wordnet. Our best run has obtained a 4th - 0.4008 MAP -. A major finding is that LCA fits better

Analysis of Word Sense Disambiguation-Based Information Retrievald. We try, through this paper, to give a deep analysis of the reasons behind these failures. During our participation at the Robust WSD task at CLEF 2008, we performed experiments on monolingual (English) and bilingual (Spanish to English) collections. Our official results and a deep analysis are de

The aim, as usual, was to test the p- formance of a wide range of multilingual information access (MLIA) systems or s- tem components. This year, 100 groups, mainly but not only from academia, parti- pated in the campaign. Most of the g
