Word Sense Disambiguation
Word Sense Disambiguation is a subtask of semantic tagging, which consists of assigning a semantic class (sense) to a lexical item as specified by a semantic lexicon. If the semantic lexicon specifies more than one sense for a particular lexical item, a disambiguation procedure is needed to decide upon the most appropriate sense(s) for any given instance of the lexical item in text. WSD is not a self-contained application, but it may be included as an integrated part of a semantic processor.
