Abstract :
Semantic cohesion is one kind of semantic relation between two words. It could be represented by the relation between the respective semantic meanings of the two words, and is useful for WSD problem in a collocation. In this paper, an HMM model was proposed to automatically label semantic meaning pairs for collocations composed of a noun and a verb. In order to find a suitable system of semantic class to represent individual word, three semantic classification methods based on the information from HowNet system, are proposed and compared with each other. The experimental results showed that one of the three classifications is appropriate for representing individual word. And these results also showed that the HMM model is helpful to captures the semantic cohesions properly.
