结合编辑距离和Google距离的语义标注方法*

提出了一种在领域本体指导下对网页进行语义标注的方法。该方法利用编辑距离和Google距离从词语的语法和语义两方面综合度量词汇与本体概念之间的语义相关度，从而在网页与本体之间建立映射关系。此外，对网页进行语义标注后，利用标注结果对本体进行有效扩充，使本体更趋于领域化。实验结果表明该方法是行之有效的。

Approach for semantic annotation based on edit distance and Google distance

This paper presented a methodology for semantic annotation of Web pages with domain-specific ontology. This new approach used the edit distance and the Google distance to measure the relativity between words and ontology concepts in terms of syntax and semantic, so as to link Web pages with ontology concepts. In addition, it enriched the ontology with the results of annotation to make the ontology greatly cover the domain knowledge. The experimental result shows that this method is significantly effective.
