TAILIEUCHUNG - Lecture Notes in Computer Science- P98

Lecture Notes in Computer Science- P98:This year, we received about 170 submissions to ICWL 2008. There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings. The authors of these accepted papers | 474 X. Wang F. Fang and L. Fan Class Category covers many resource types depends on the structure application format etc. This class is defined carefully and amply. In Category we reference the learning object hierarchy made by David Wiley and this kind of taxonomy is based on the structural qualities of learning object show in Table 1. We also list the resource format as many as we can. Table 1. Learning object hierarchy Taxonomy Explanation Example Fundamental Single digital resources a JPEG picture Combined-closed Combination of fundamental elements winch can t be restituted a video Combined-open Combination of abundant digital resources which can be acquired and restituted directly a web Generative-presentation Low-level logical reasoning and structure of learning objects a JAVA applet Generative -ms true tional Interactive logical reasoning and structure of different learning objects an EXECUTE instructional transaction shell Relationships There are two kinds of basic relationships As an ontology OntoLo has all of the inherent relationships such as Is-a Kind-of Instance-of etc. As an education ontol-ogy Domain Ontology there are some special relations as well such as Composed-of Target-of etc. Properties After all the classes are created we should define the properties slots in Protégé of classes. We set the properties by referencing the CELTS-42 Metadata Application Fig. 2. An instance and part of its properties Ontology-Based Description of Learning Object 475 Specification of Basic Education Resource which is based on CELTS-3 Learning Object Metadata and faces to the basic education in China. One thing should be noticed is that all subclasses of a class inherit the slots of their super-class. Subclass can have properties themselves. Slots can have different facets describing the value type allowed values the number of the values cardinality and other features of the values the slot can take. For example the value of a title
