Abstract
For UFRGS’s participation on CLEF’s Robust task, our aim was to compare retrieval of plain documents to retrieval using information on word senses. The experimental runs which used word- sense disambiguation (WSD) consisted in indexing the synset codes of the senses which had scores higher than a predefined threshold. Several thresholds were tested. Our results have shown that the best WSD runs did not present a significant improvement in relation to the baseline run in which plain documents were used. In addition, a comparison between two alternative disambiguation systems has shown that one outperforms the other in all experimental runs.
