Knowledge base
One of
the aims of Multibook is to offer different lessons for different users.
There are two possible ways to accomplish this: either a huge number of
compiled lessons are stored – the disadvantage of this approach is not
only the amount of storage but also the static character of such lessons
– or the lessons are generated individually for each user. Since the dynamic
composition also facilitates the exchange or modification of information
junks, Multibook follows the second approach. The Multibook system can
adapt the lessons both thematically and with respect to the presentation
to the specific learner. This is accomplished by using metadata which are
realized – among other description – by appending concepts and relations
described as follows:
Every information contained in Multibook is partitioned in small segments (an image, an applet, a paragraph of text, etc.) These so called media bricks are connected such that the system can identify which of them are related. These relations are called rhetoric-didactic relations. The properties of the presentation – e.g. the level of difficulty - is constituted by these. Also for the thematical aspect of the composition, additional metadata are used: The media bricks are related to the according concepts. The concepts covering the complete domain are connected via semantic relations describing the factual relationship between the concepts. The concepts and the sematc relations together build the ConceptSpace. Therefore, the knowledge base is divided into the ConceptSpace providing for an outline of a lesson, and the MediaBrickSpace, from which the information junks are composed according to the preferences of the learner.
