知識在組織中是很重要的資產,因此知識管理是組織保有競爭力的關鍵。由於組織中的知識分散、複雜、多變,造成組織內的知識無法有效的利用。本論文提出一個方法,透過Zachman Framework所建議的六各維度和XML的技術彈性的將組織內的知識組織為半結構知識文件。知識不只需要被有效的管理,還需要能夠有效的利用,才有他的價值。這些半結構知識文件因為其結構多變、不規則,增加了找尋的困難。隱藏語意索引(Latent semantic indexing)是個有效的自動化方法,根據使用者需求的相關文句來幫助我們找出相關的組織半結構知識文件。除此之外,隱藏語意索引(LSI) 也可以處理同義字和多義字的問題,有效的提昇找尋結果的正確性。因此本篇論文主要是提出一個管理組織內部知識的架構,並透過隱藏語意索引(LSI)的方法來將有用的知識在有效的時間內送達有需求的人。

Knowledge is a very important asset in organizations, so knowledge management is the key point that organizations reserve competitiveness. Because knowledge of organizations is distributed, complex, and variable, it often causes that knowledge in organizations cannot be used effectively. This thesis will bring up a way, which is through the six dimensions Zachman Framework suggesting and technology of XML, to elastically organize knowledge of organizations into Semi-structured knowledge. Knowledge needs not only to be managed effectively but also to be used with effect, and then its value appears. Because the structures of these Semi-structured knowledge documents are variable and irregular, they increase the difficulty to search. Latent semantic indexing is a useful and automatic way to help us to find out relative Semi-structured knowledge documents according to relative sentences or articles of users’ demand. Besides, Latent semantic indexing (LSI) can also deal with problems of synonyms and antonyms, and promote the accuracy in searching for solutions. Hence, this thesis is main to provide a framework of managing knowledge inside an organization, and via the way of LSI to send useful knowledge to needful people at effective time.
