摘要: 一般來說,傳統專家系統的知識庫有其特殊的資料結構以及推論的方式,由知識再用性以及分享性的著眼點看來,這些知識庫的價值並不高。因此我們提出基於物件導向的劇本模式來達成一致性的知識庫管理以及推論方式,使得知識庫在設計上具有再用性、分享性以及維修性,並且可由不同性質的應用程式來共同使用以及維修。根據劇本模式,我們發展出一套物件導向規則庫管理系統提供使用者兩方面的支助:一方面提供獨立的規則編輯程序,給使用者管理、維修知識庫;而另一方面則提供獨立的規則執行程序,給使用者進行推論。為了應付網路環境中分散式知識庫的管理以及推論,我們也提出分散式劇本模式來擴充現有的系統架構。對於幾個相關的規則庫管理系統以及知識庫管理系統,我們亦在多方面做了比較。其中有幾項是我們系統表現較優,包括知識的抽象化、知識庫的維修、知識的分享、知識的再用以及分散式知識庫的管理與推論。
We propose a new model, Drama Model, under the object-oriented paradigm for manipulating the knowledge base and inference procedures of general rule-based applications and expert systems. Based on Drama Model, modules of rules can be constructed as a reusable, sharable, and modifiable knowledge base such that heterogeneous rule-based applications can share them. To manage the knowledge base effectively and efficiently, an OORBMS (object-oriented rule base management system), which supports independent procedures of rule editing and rule execution for the knowledge base, is also developed. For catering network environment, Distributed Drama Model is also proposed in this thesis. Comparing our OORBMS to traditional RBMS or KBMS on the viewpoint of knowledge management, ours provides higher qualities of the knowledge base in several aspects: knowledge abstraction, persistent-knowledge management, knowledge share, knowledge reuse, distributed knowledge and distributed inference.
