Abstract

A graphical user interface for an object-oriented query language, GOQL, is presented, GOQL is a part of a prototype knowledge base management system which is based on an object-oriented semantic association model, OSAM. GOQL consists of a graphical browser and a graphical querying module. The browser allows a user to browse through a complex knowledge-base schema graphically and prune it into a desired level of abstraction and details before the querying process. In the querying module, there are two modes, OQL and graphical OQL. The OQL mode is provided for knowledgeable users to directly type in the OQL command. In the graphical OQL mode, the user is guided through the formation of the query. It is noted that the object-oriented nature and the increased semantics of the underlying model and query language pose new challenges in user interface design due to their added complexity. On the other hand, these features also provide more information to the system in order to make the user interface more intelligent.<>

面向对象查询语言的图形界面

提出了面向对象查询语言GOQL的图形用户界面，GOQL是基于面向对象语义关联模型OSAM的原型知识库管理系统的一部分。GOQL由图形浏览器和图形查询模块组成。浏览器允许用户以图形方式浏览复杂的知识库模式，并在查询过程之前将其修剪成所需的抽象和细节级别。在查询模块中，有OQL和图形OQL两种模式。OQL模式提供给知识渊博的用户直接输入OQL命令。在图形OQL模式中，用户被引导完成查询的形成。值得注意的是，由于底层模型和查询语言的复杂性增加，面向对象的特性和语义的增加给用户界面设计带来了新的挑战。另一方面，这些特性也为系统提供了更多的信息，使用户界面更加智能化。>
