Back to our roots for retrieving very short passages
Nada Naji|Jacques Savoy
This article tackles the task of retrieving very short documents via even shorter queries. The problem on hand may relate to retrieval tweets, image and table captions, text messages (SMS) sponsored among others. In such cases, document and/or query expansion using thesauri other external resources (e.g., Wikipedia) usually available World Wide Web (WWW) are proven be effective approaches. However, focus this paper is that written in lesser known languages for which WWW limited use. Our experiments based two main corpora extracted from historical manuscripts Latin Middle High German. We found whose lengths quite similar queries given no enrichment available, classical tf-idf model performs as satisfactorily more complex models do, if not better sometimes.
