Abstract: Relation pattern extraction and information extraction from the web. This article presents an information extraction method which collects additional information on the web so as to enrich already existing information and then fill in a knowledge base. Our method is based on lexical and syntactical patterns, both used as search queries and extraction patterns to allow the analysis of unstructured documents. To do so, we first defined relevant criteria coming from the analysis phase so as to ease the discovery of new values. MOTS-CLES : Construction de patrons, extraction d’information, extraction d’entités nommées, syntaxe en dépendances, apprentissage de patrons d’extraction, web comme corpus.
