| 摘要: |
| 提出了一种面向网络信息的层次过滤模型及其体系架构，该模型分为本体过滤层、需求过滤层和兴趣过滤层.本体过滤层中，利用本体为基础对信息内容进行语义描述，实现信息的计算机理解与过滤；在需求过滤层，模型通过理解用户所提出的需求中所包含的语义，进而更加准确地通过过滤规则进行信息流过滤；在兴趣过滤层，用户兴趣通过特定方式表达，并通过语义相似度计算实现第三过滤层. |

| Abstract: |
| Asemantic based three-layer web information filtering model and its architecture are presented,which comprises ontology filtering layer,requirement filtering layer,and interest filtering layer.In ontology filtering layer,contents of information are described formally based on ontology,and those information which cannot be understood by ontology can be recognized and filtered;in requirement filtering layer,web information would be filtered through calculating the semantic similarity degrees between user requirements and information features;in interest filtering layer,the user interests are described based on formal semantic,and further,the information can be filtered by comparing the similarity of user interest and information content. |
| Key words: semantic information filtering layer model ontology |
