| 摘 要: 针对SCORM学习对象模型语义缺失的问题，结合语义Web本体标注的技术，提出一种使用语义标注实现 SCORM模型本体化的方法。该方法从SCORM规范中提取语义信息构建SCORM本体模型，以公理的方式形式化表示了 SCORM的语义信息和语义约束。并以此为基础在现有SCORM学习资源中扩展语义标注信息，使SCORM学习资源中的 元素和属性映射到SCORM本体的类和属性，使用SCORM本体模型为学习资源提供语义约束和知识推理。该方法遵照 SCORM语法、语义，以及扩展思想，将SCORM信息模型映射为SCORM知识模型，把SCORM学习对象的使用提高到 知识重用和知识互操作的层面。 |

| Abstract: Focusing on the semantic loss of the SCORM leaning object model and combining with the semantic Web ontology annotation technology,the paper proposes a method applying semantic annotations technology to implement semantic SCORM information model.This method extracts semantic information from the SCORM specification to structure SCORM ontology,in which the SCORM semantic information and semantic constraints are formalized through axioms.Then on this basis,the existing SCORM resources can be extended with some semantic annotation,to map elements and attributes in the SCORM model to the SCORM ontology.Based on the syntax and semantics of SCORM,this research transforms the SCORM information model into the SCORM knowledge model,and promotes utility of SCORM learning objects to knowledge reusability and knowledge interoperability. |
