This thesis studies the principle of ais, the types of its system structure and the key factors which affect its evolution, explains the necessity and feasibility of ais based on event approach, emphasizes how to use the entity - relation approach and the real ( r is for " resource ", e for " event ", a for " agent ", l for " location " ) semantic model to design the integrate event - driven database and expects intelligent decision support system ( idss ), the application of data warehousing and olap technology in decision support system ( dss )
文章的研究思路是：從會計信息系統體系結構的角度，研究系統體系結構的類型及其演變的主要影響因素。論述了基於事項會計的會計信息系統的現實必要性和技術可行性；重點研究了現代信息技術環境下，基於事項會計的會計信息系統體系結構、如何運用e - r概念模型與real業務過程語義模型分析和設計集成業務數據庫、基於事項會計的會計信息系統原理和結構；並展望了數據倉庫和olap聯機分析處理技術在決策支持系統dss中的應用，即基於企業數據倉庫的智能決策支持系統（ idss ）前沿研究。 -
A fuzzy image data model and a concept of fuzzy space are proposed, in which model visual feature, spatial feature and semantic feature are used for super feature in order to utilize advantage of traditional relation database as well as characteristics of image data and fuzzy retrieval. based fuzzy space, a method of similarity measurement of image is presented to support fuzzy features - based image retrieval and satisfy user ' s query requirement for image. in the thesis, a semantic template and the mechanism of dynamic relevant feedback are defined so that it can express user ' s query semantic and improve retrieval precision and useable capability for image retrieval
研究了模糊檢索方法和相關反饋機制在圖象檢索中的應用，提出了一種模糊圖象數據模型和模糊空間的概念，該模型將可視特徵、空間特徵、語義特徵看作超屬性，既充分利用了傳統關系數據庫的優點，同時又考慮了圖象數據以及模糊查詢的特點，文中提出的模糊空間和模糊相似性度量方法能支持基於模糊特徵的圖象查詢，較好地體現用戶圖象查詢的應用需求，文中定義的語義模板和相關反饋機制能在一定程度上表達用戶的查詢語義，提高圖象檢索的準確率和易用性。 -
