| Abstract | This paper deals with the main problems that arise in the query translationprocess in dictionary-based Cross-lingual Information Retrieval (CLIR):translation selection, presence of Out-Of-Vocabulary (OOV) terms andtranslation of Multi-Word Expressions (MWE). We analyse to what extent eachproblem affects the retrieval performance for the Basque-English pair oflanguages, and the improvement obtained when using parallel corpora freemethods to address them. To tackle the translation selection problem we providenovel extensions of an already existing monolingual target co-occurrence-basedmethod, the Out-Of Vocabulary terms are dealt with by means of a cognatedetection-based method and finally, for the Multi-Word Expression translationproblem, a naïve matching technique is applied. The error analysis showssignificant differences in the deterioration of the performance depending onthe problem, in terms of Mean Average Precision (MAP), the translationselection problem being the cause of most of the errors. Otherwise, theproposed combined strategy shows a good performance to tackle the threeabove-mentioned main problems. |
