摘要
词义消歧对自然语言处理领域许多问题的研究具有重要的理论和实践价值。针对该问题,提出了一种基于知网的中文词义消歧算法。为了考虑上下文词汇对词义消歧的不同影响,以语义相似度计算为基础,设计了三种语义联系强度计算方法,并且制定了四条词义消歧规则,依此实现中文词义消歧。实验数据显示该方法可获得65%左右的召回率和75%左右的准确率。
The automatic disambiguation of word senses has great theeretical and practical significance in many fields of natural language processing. Presents an approach to Chinese word sense disambiguation based on HowNet. In order to take into account different effects of context to word sense disambiguation, three methods of calculating sense relation strength and four related rules are designed based on semantic similarity computing. The recall/accuracy rate of experiment are respective about 65% and 75%.
