Abstract: Methods and apparatus related to word sense disambiguation utilizing hypernyms. In some implementations, one or more senses of a word are determined based on hypernyms for the word and an association of the word to the one or more senses is stored. In some implementations, a target word in a textual segment is identified and a word sense to assign to the target word is determined based on hypernyms that are associated with the target word.
