Evaluation Arithmetic of Topic Relevance Based on Dynamic Matching

摘要: 本文在基于元数据的判定方法和基于网页内容的语义判定方法的基础上, 借鉴哈弗曼编码的思想, 提出了一种基于动态匹配的主题相关度算法.该算法通过分析输入数据的类型来采用相适应的判定方法.实验结果表明, 从准确率和速度相统一的角度看, 本文提出的主题相关度算法要优于现有算法.Abstract: An evaluation arithmetic of topic relevance based on dynamic matching is presented in this paper, which is based on evaluation of metadata and evaluation of semantics based on web content.The computing model can adjust automatically based on the type of inputted data and is able to settle in great part the contradiction between process speed and accuracy rate.The experimental results demonstrate that the computing model presented in this paper perform better than present approaches.
