中文摘要
文件為組織機關運作過程中所產生的記錄,其中蘊含許多組織運作的資訊與智慧。隨著文件電子化這股趨勢,有越來越多文件是以電子化的格式儲存於組織機關內部。在這二十一世紀的開端,知識經濟時代來臨,知識管理嚴然成為當代企業營運最重要的議題,組織進行知識管理的第一步就是要從事文件管理。然而文件的可貴之處不僅在於其本身,知識管理最終的目的是要確保組織內部現存的知識可被有效地被應用到組織利益上,亦即須將文件資料轉化為有用的資訊,藉以協助管理者制定正確的決策。因此,如何透過系統化的方式由大量文件中發掘與彙整出一有助於決策的資訊與知識便成為文件導向決策支援系統的重要任務。
目前關於索引、資訊檢索及文件探勘等技術的相關研究數量甚多,但仍較少針對應用這些技術來建構出有助決策的決策支援系統之研究,使它們的應用價值仍受到侷限。由於文件中含有許多決策過程及結果相關的資訊,因此,文件導向決策支援系統的關鍵在如何由大量文件中找出決策相關的核心知識。本研究透過資訊探勘方法的開發及雛型系統之實作,並以管理學門國際期刊及國際研討會分級計畫的會議記錄為例,提出文件導向決策支援系統的建置方法,藉此說明和展現文件導向決策支援系統其可行性與價值。其中,由本研究所提出的資訊探勘方法結合了本體論、索引及資訊檢索等相關技術,經過一連串的處理步驟之後,找出埋藏於會議紀錄裡的事件相關資訊。最後,再以Gantt圖與職責圖的形式呈現由會議紀錄中所發掘出來的程序性知識。
Abstract
Documents are records of activities and related knowledge generated from organizational operations. With the trend of more and more documents being stored in the digital form, how to manage this knowledge has become an important issue. The first step is to manage knowledge is to activate the content of knowledge. These documents stored in an organization can not only be retrieved for future reference but also be analyzed to assist managers in making the right decision. Therefore, it is important for a organization to develop document-driven DSS that can discover useful knowledge from a large amount of documents in an organization.
Most previous research on document management are focused on the indexing, retrieval and mining of documents, few applications have investigate how this technology can be used to construct knowledge for decision support. The purpose of this research is to propose an approach for developing document-driven DSS. In particular, the research proposes a methodology that combines ontology, indexing, and information retrieval technology to develop event scheme that can be used as a basis for the document-driven DSS. A prototype system has been designed to analyze documents collected from a journal ranking exercise to demonstrate the feasibility of the proposed approach.
