Semi-structured Data Models Based on Description Logics

摘要

In recent application areas such as data integration, access to data on the web, and digital libraries, so called semi-structured data models have been proposed, which are graph-based data models that provide flexible structuring mechanisms. The Extensible Markup Language (XML), which has been introduced as a standard for representing structured documents on the web, can in fact also be considered a model for semi-structured data. Hence it seems natural to adopt Description Logics and the associated reasoning services also for representing and reasoning on semi-structured data and XML. In this paper, we provide a framework to represent a XML document using Description Logic approach. The XML document is about the students and the teachers that is easily understanding. The issues we pay attention to are the basis of reasoning on XML documents.
