Abstract

Cette invention se rapporte à des procédés et à des dispositifs conçus pour accepter une question d'utilisateur en langue naturelle (par exemple, en anglais), pour explorer une base de données électronique à la recherche de phrases susceptibles de fournir à la question des réponses ayant une signification sémantique, pour identifier ces phrases qui sont supposées répondre à la question et pour quantifier le degré d'exactitude de la réponse que ces phrases apportent à la question.
