Division of Example Sentences Based on the Meaning of a Target Word Using Semi-Supervised Clustering
14 years 11 months ago
In this paper, we describe a system that divides example sentences (data set) into clusters, based on the meaning of the target word, using a semi-supervised clustering technique....
