在文献检索系统中，检索需求通过关键词来描述，关键词对检索需求的覆盖程度决定了检索结果能否满足检索需求。为了改善检索需求的提炼过程，提高关键词对检索需求的覆盖程度，描述一种基于概念扩展的文献检索系统的设计与实现。与传统的文献检索系统相比，该系统具备关键词概念扩展的能力，该系统能够基于百科网页自动构建概念网络，通过概念相似度计算从概念网络中选择与关键词最相近的概念进行关键词的概念扩展，以此来改善检索需求的提炼、提高对检索需求的覆盖，从而达到优化检索体验的目的。
在文獻檢索繫統中，檢索需求通過關鍵詞來描述，關鍵詞對檢索需求的覆蓋程度決定瞭檢索結果能否滿足檢索需求。為瞭改善檢索需求的提煉過程，提高關鍵詞對檢索需求的覆蓋程度，描述一種基于概唸擴展的文獻檢索繫統的設計與實現。與傳統的文獻檢索繫統相比，該繫統具備關鍵詞概唸擴展的能力，該繫統能夠基于百科網頁自動構建概唸網絡，通過概唸相似度計算從概唸網絡中選擇與關鍵詞最相近的概唸進行關鍵詞的概唸擴展，以此來改善檢索需求的提煉、提高對檢索需求的覆蓋，從而達到優化檢索體驗的目的。

In the literature retrieval system, the retrieval requirement is described by keyword, and the coverage of the retrieval requirement will de-termine whether the retrieval results can meet the needs of the search. In order to improve the extraction process and the coverage of re-trieval requirement, designs and implements a literature retrieval system based on concept extension. Compared with the traditional litera-ture retrieval system, the system has the ability to expand the keywords by using concept network. Aiming to improve the extraction pro-cess, the coverage of retrieval requirement as well as optimizing retrieval experience, the system can automatically construct the concept network based on the encyclopedias web page, extends keywords by selecting the concepts from concept network which are the most simi-lar to the keywords.
