Concepts relevant to natural language content may be identified using an ontology. The natural language content may be tokenized and normalized. Using the tokenized content, one or more candidate concepts within the ontology may be identified. Concepts relevant to the natural language content may be selected using the identified concepts and the relationships between concepts defined within the ontology. A spreading activation process may be used to identify related concepts. The spreading activation process may be iterative and/or may reach multiple generations of connected concepts within the ontology. The relevant concepts associated with the natural language content may be used to index the natural content, identify related content, provide targeting advertising related to the natural language content, and the like.

Les concepts propres au langage naturel peuvent être identifiés au moyen d'une ontologie. Le contenu du langage naturel peut être segmenté en unités et normalisé. A l'aide de ce contenu segmenté en unités, on peut identifier un ou plusieurs concepts candidats au sein de l'ontologie. Les concepts propres au contenu du langage naturel peuvent ainsi être identifiés et sélectionnés, et la relation entre les concepts peut être définie au sein de l'ontologie. Un processus dactivation de diffusion peut être utilisé pour identifier ces concepts associés. Ce processus peut être itératif et/ou atteindre plusieurs générations de concepts connectés au sein de l'ontologie. Ces concepts propres au contenu du langage naturel et associés entre eux peuvent être utilisés pour indexer le contenu naturel, identifier le contenu associé, donner des indications ciblées associées au contenu du langage naturel, etc.
