摘要
同义词的自动发现和识别在信息检索领域有着重要的研究意义和应用价值。为了提高同义词自动识别的效率,本文提出了基于PageRank算法的汉语同义词自动识别方法。该方法把词汇之间解释与被解释的关系看成是一种超链接,把PageRank值看成是体现词汇之间语义相似性的衡量指标,然后根据语义相似度的大小识别同义词。通过算法提取测试,结果表明:利用基于PageRank算法来自动发现和识别同义词具有可行性和实用性。
Automatic recognition of synonyms plays an important role in information retrieval. In order to enhance the ability of synonyms recognition, this paper presents a method based on the PageRank algorithm. The authors analyze the relation links between a given word and other words. Then, the PageRank algorithm is used to calculate the similarity degree and the synonyms are found in the associated words. The result obtained from the use of the approach for synonyms recognition shows that the PageRank algorithm is feasible and practical.
