1. A computer-implemented method for determining concept attributes for a concept term, comprising: receiving a concept term; determining one or more word senses for the concept term; selecting a word sense from the one or more word senses; based on the selected word sense, determining one or more conceptually similar terms for the concept term; determining that at least one of the one or more conceptually similar terms is a concept attribute for the concept term; generating a mapping to associate the concept attribute with the concept term; and storing the mapping in an onomasticon.
