中文摘要 | 智慧型決策支援系統(intelligent decision support systems)的特點是可以同 時處理定性和定量資料於同一個系統中,以同時執行各種知識推論及數量模式之 運算。黑板架構(blackboardarchiteecture)的做法是將決策支援求解過程的資料、模 式和知識運用情形記錄於一共同工作區-稱之為黑板資料區(blackboard data structure),將模式及知識記錄在所謂的知識源(knowledgesources)中,並提供較有 彈性之控制機制,應可提供較佳的解釋功能。以黑板架構為基礎的智慧型系統多 應用在科學及工程方面,在管理方面卻寥寥無幾;而管理問題多半屬於半結構性 或非結構性,良好的解釋應為智慧型決策系統之重要功能。本研究就銀行授信審 查之專業領域知識(domein knowledge),運用黑板架構的階層化問題表現方式、模 組化知識源分類、及彈性控制之特性,建立提供完善解釋功能之智慧型授信決策 支援系統。配合黑板架構的特性,以展現黑板資料區中系統正解決問題點的方式 解釋"What?"之問題;以展現正啟用知識源的方式解釋"Why?"之問題;以展現系統 達到現階段問題點過程的方式解釋"How?"之問題;並以展現系統現階段距離目標 差距的方式解釋"Where?"之問題。本研究應可提昇決策者使用智慧型授信審查系 統之意願及信心。 |
英文摘要 | Blackboard architecture can support a well-organized explanation facility due to itsstructurization of problem solving space, modularization of domain knowledge, and flexibility of reasoning control. Since most managerial consultation problems are unstructured or semi-structured, good explanation facility should be able to enhance the consultation effectiveness. In this paper, we develop an explanation facility on the blackboard architecture using the loan evaluation as an example. To explain the consultation process for loan evaluation, the system answers questions such as "What?"," Why?", "How?", and "Where?" with a friendly user interface. Answering "What?", the system displays the solution nodes on which the reasoning process is currently on. Answering "Why?", the system depicts the contents of the working knowledge source. Answering "How?", the system portrays the solution path, including all the past solution nodes and knowledge sources up to the current state. Answering "Where?", the system reveals the potential future path facilitated by the goal-driven agendacontrol mechanism built in the blackboard architecture. The inclusion of explanation facility canpotentially increase the willingness and confidence of decision makers in using intelligent decision support systems. |
