Chinese Word Sense Disambiguation with PageRank and HowNet
Jinghua Wang, Jianyi Liu, Ping Zhang · International Joint Conference on Natural Language Processing · 2008
Word sense disambiguation is a basic problem in natural language processing. This paper proposed an unsupervised word sense disambiguation method based PageRank and HowNet. In the method, a free text is firstly represented as a sememe graph with sememes as vertices and relatedness of sememes as weighted edges based on HowNet. Then UW-PageRank is applied on the sememe graph to score the importance of sememes. Score of each definition of one word can be computed from the score of sememes it contains. Finally, the highest scored definition is assigned to the word. This approach is tested on SENSEVAL-3 and the experimental results prove practical and effective.
