QA Builder: a visual toolkit for building multimedia knowledge-based systems with immediate feedback

QA Builder is a toolkit for building interactive knowledge-based systems for domains in which the domain knowledge can be expressed as a sequence of questions and answers. It integrates knowledge acquisition, knowledge-base validation, multimedia authoring, and user interface design and validation in a unifying framework. It is unique in that it treats non-textual information such as video, audio, and graphical images as integral parts of the domain knowledge, and that it provides authors with immediate feedback. This paper describes the QA Builder with an emphasis on the object-oriented visual editors.
