Extracción crosslingüe de documentos usando mapas semánticos no-lineales

A non-linear semantic mapping procedure is proposed for cross-language document retrieval. The method relays on a non-linear space reduction technique for constructing semantic embeddings of multilingual document collections. In the proposed method, an independent embedding is constructed for each language in the multilingual collection and the similarities among the resulting semantic representations are used for cross-language document retrieval. Two variants of the proposed method are implemented and compared with a state-of-the-art cross-language information retrieval technique. It is shown that, for some specific tasks, the proposed method outperforms the conventional one.
