Example-based Discovery of Unconventional Chinese Semantic Collocations
Xiaoxi Huang · 2008
Semantic collocation is the tendency for lexical words to occur together.It is constrained by the syntactic structure and semantic cohesion between its lexical items.Besides conventional semantic collocations,there are also unconventional semantic collocations whose semantic combination is far beyond people's conventional cognitive sense.They are pervasive in all types of writing and considered to be the focus of rhetorical and metaphorical expressions which could be a real difficulty in Natural Language Understanding.In this paper,the characteristics of unconventional semantic collocations and their psychological triggering process are first analyzed and an example-based model is then proposed to automatically discover unconventional semantically collocated word pairs.The experiment is carried out on Chinese verbal collocations.The precision is 81.5% and recall is 80.7%.The experimental results show that the example-based model is effective in detecting unconventional semantic collocations.
