Semantic knowledge in Question-Answering systems
Résumé
QA systems need semantic knowledge to find in documents variations of the question terms. They benefit from the use of knowledge resources such as synonym dictionaries or ontologies like WordNet. Our goal here is to study to which extent variations are needed and to determine what kinds of variations are useful or necessary for these systems. This study is based on different corpora in which we analyze semantic term variations, based on reference sets of possible variations.
