PROBLEM SOLVING SUPPORT BY THE MULTI-LAYER HYPERMEDIA MODEL

Abstract

Hypermedia is a suitable tool to describe knowledge and to support the problem solving process. Hypermedia nodes contain information elements and links represent relations between them. The users of present electronic materials, however, cannot modify the contents of the materials and include their individual knowledge. A new hypertext model, called Multi-Layer Hypermedia Model (MLHM) was developed to support the manipulation of the presented knowledge. With applying this model, electronic materials can be created that express writer´s as well as user´s knowledge and support the problem solving process. When using HTML as the basic layer of the model, the hypermedia system can expand the usability of HTML based materials.
