| 中文摘要: |
| 在海量信息环境下,网络信息的杂乱,严重影响用户的有效利用.基于页面内容的可用性评估成为研究人员关注的热点.提出了一种形式概念分析的单页面内容概念树构建方法,该方法以单个页面作为切入点,以页面段落为对象,段落中的动名词为属性,构造概念格,利用剪枝命名转换规则,构建概念树.实验结果表明,该方法构建的概念树对页面内容重构以及页面分类合理性判断有较好的效果,可作为We b内容可用性评估的一种手段. |

| In huge information environment, it is serious to affect the effective use of the user with random network information.The Web usability evaluation of page content has become a hot point of research.This paper proposes a method for constructing content concept tree of single web page based on formal concept analysis FCA, which is based on a single page as a starting point,and page paragraph regarded as the object, noun or verb in the paragraph as at ributes, using FCA to construct concept lat ice, with pruning, named and converted rules to construct the concept tree.Experimental results show that the approach used to build the concept tree has a bet er effect on page content reconstruction and reasonable classification judgment. It can be used as a method of usability evaluation of Web content. |
