... Non-Literal Word Sense Identification Through Semantic Network Path Schemata Eric lverson, Stephen Helmreich Computing Research Lab ... Here the program follows paths from existing word senses stored in a semantic net- work to other closely associated word senses. By examining the shape of the resultant path, we can determine ... properties of a sense. Source con-...

... Introduction Sense induction is the task of discovering automat- ically all possible senses of an ambiguous word. It is related to, but distinct from, word sense disam- biguation (WSD) where the senses ... the generated word. Then, the word sense is selected based on the word, neighbor, and topic. Boyd-Graber et al. (2007) extend the topic mod- eling framework to include WordNet...
