Abstract

This paper describes the experiments submitted by UNED’s NLP Group to the WebCLEF 2005 track in the bilingual English to Spanish task. We present two different runs: i) a simply search over the whole content of the documents; ii) a series of restricted searches over given fields according to their descriptiveness. Our newly developed approach for searching ordered fields performs 80% better than the baseline. We also describe a non-supervised approach to translate out-of-vocabulary words.
