Learning a vocabulary word requires seeing it in multiple informative contexts. We describe a system to generate such contexts for a given word sense. Rather than attempt to do word sense disambiguation on example contexts al- ready generated or selected from a corpus, we compile information about the word sense into the context generation process. To evaluate the sense-appropriateness of the generated contexts compared to WordNet examples, three human judges chose which word sense(s) fit each ex- ample, blind to its source and intended sense. On average, one judge rated the generated ex- amples as sense-appropriate, compared to two judges for the WordNet examples. Although the system’s precision was only half of Word- Net’s, its recall was actually higher than WordN...
