KNOWLEDGE REPRESENTATION IN ADAPTIVE SYSTEMS OF DISTANCE LEARNING

Abstract

In basis of adaptive distance learning systems ( ASDO ) laid a knowledge base. Knowledge Base ASDO - a special kind of database designed for knowledge management (metadata): collection, storage, retrieval and adaptive delivery of learning material. Model of knowledge representation ASDO includes all stages of functioning of the knowledge base.

The basis of the knowledge base of ASDO consist of frame-model of knowledge representation. But in contrast to the classical model, which reflected the final version of knowledge representation, the proposed model includes all stages of functioning of the knowledge base.

Benefits of the proposed model construction BZ: structuring knowledge, dynamic knowledge management; optionality determine all the parameters, the ability to track and manual change mode; adaptive issuing educational material.
