Word Sense Disambiguation
WSD is an NLP problem of assigning concepts to words
Any automatic WSD algorithm does at least the following:
- defining a “sense repository” that describes different concepts
-
assigning concepts to words in context
- Ambiguity: one word is related to several concepts
- Variability: several different words are related to the same concept
If we link all words and concepts, we’ll get a Semantic Network
- for example, WordNet is such a network
