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, the selected word sense indicating a particular semantic context of the concept term; based on the selected word sense, determining one or more conceptually similar terms for the concept term; determining whether each of the determined conceptually similar terms is within the particular semantic context of the concept term as indicated by the selected word sense, each of the conceptually similar terms that are determined to be within the particular semantic context of the concept term being a suitable concept attribute for the concept term; generating a mapping to associate the suitable concept attributes with the concept term; accessing an onomasticon, the onomasticon comprising a plurality of terms and a plurality of attributes associated with the plurality of terms; and storing the mapping in the onomasticon.
