The goal of the research here presented is to identify which aspects of Wikipedia can be exploited to support the process of automatically building Multilingual Domain Modules from textbooks. First, we have defined a representation formalism for Multilingual Domain Modules that is essential for Technology Supported Learning Systems which aim to serve a globalized society. To our knowledge, no attempt has been made at achieving domain models that consider multiple languages. Our approach combines Multilingual Educational Ontologies with Learning Objects in different languages. Wikipedia is a valuable resource to accomplish this purpose. In this scenario, we have developed LiDom Builder, a framework that uses Wikipedia as an additional knowledge base for the automatic generation of Multilingual Domain Modules from textbooks. The framework includes domain-independent term extraction methods to identify which topics of Wikipedia are related to the domain to be learnt and, also, extracts their equivalents in other languages. In order to complete the Educational Ontology, we have defined a method to extract pedagogical relationships from Wikipedia and other general-purpose knowledge bases. From this task, we highlight the extraction of relationship that will allow the sequencing of the topics in Technology Supported Learning Systems. In addition, LiDom Builder takes advantage of the structured contents of Wikipedia to identify text fragments that can be used for educational purposes, classifies them and generates their corresponding Learning Objects. The interlanguage links between topics of Wikipedia are used to create Learning Objects in other languages.

此处提出的研究目的是确定可以利用Wikipedia的哪些方面来支持从教科书自动构建多语言域模块的过程。首先，我们定义了多语言域模块的表示形式，这对于旨在为全球化社会服务的技术支持学习系统至关重要。据我们所知，尚未尝试实现考虑多种语言的领域模型。我们的方法将多语言教育本体与不同语言的学习对象结合在一起。维基百科是实现此目的的宝贵资源。在这种情况下，我们开发了LiDom Builder，该框架使用Wikipedia作为从教科书自动生成多语言域模块的附加知识库。该框架包括与领域无关的术语提取方法，以识别Wikipedia的哪些主题与要学习的领域相关，并且还提取其他语言的等效词。为了完成教育本体论，我们定义了一种从Wikipedia和其他通用知识库中提取教学关系的方法。从此任务中，我们将重点介绍关系的提取，以允许对技术支持的学习系统中的主题进行排序。此外，LiDom Builder利用Wikipedia的结构化内容来识别可用于教育目的的文本片段，对其进行分类并生成其相应的学习对象。维基百科主题之间的中间语言链接用于创建其他语言的学习对象。
