| 摘要: |
| 利用信息检索、本体和个性化搜索等相关知识,构建一种基于本体的个性化搜索引擎模型PSMBO。该模型由用户界面、查询请求处理模块、检索模块、查询结果处理模块、兴趣学习模块以及用户兴趣知识库和本体知识库七个部分组成。该模型在一定程度上提高了搜索引擎在查准率和查全率方面的性能。 |

| Abstract: |
| The problems of "different expression","loyal expression" and "mechanical match" in the current search engines are discussed.In combination with the theory and technology of personalized searching service,a personalized searching model(PSMBO) based on ontology is presented.This model comprises of seven modules.They are user interface,search request disposing module,searching module,result disposing module,interest learning module and user interest deposit and ontology deposit.This model improves the performance of search engine in Recall and Precision in certain degree. |
| Key words: information retrieval ontology personalization search engine |
