Initial approaches on Cross-Lingual Information Retrieval using Statistical Machine Translation on user-queries

Abstract

In this paper we propose a multilingual extension for OnAIR which is an ontology-aided information retrieval system applied to retrieve clips from a video collection. The multilingual extension basically involves allowing the user to search in several languages in a multilingual video collection. Particularly, the pair of languages we work in this paper are English and Portuguese. In order to perform query translation we use a statistical machine translation approach. Our experiments show that the multilingual system is capable of achieving almost the same quality of that obtained by the monolingual system.
