Abstract

The purpose of the following thesis is to review current approaches and tools that serve as XML to OWL mapping. My idea of approach is also presented. The main goal of each approach is to capture explicit knowledge, hidden in XML document, and record it in OWL ontology. At the beginning of this thesis I describe object domain, languages and technologies related to it. Having basic knowledge about these concept is crucial for understanding of these approaches. The thesis continues with exact description of each approach. I describe its rules and methods for mapping XML constructs into OWL concepts. At the end of description I give my critique of the approach. I point out its advantages and disadvantages. I pay special attention if tool can create its own ontology and what kind of input file does it require (XML schema or just XML document) and of course, the most important: the final result of the mapping – ontology and its instances. I also pass my judgment by comparing each approach with others. Some mapping rules are further displayed by showing the result, witch is obtained if this rule is uses on XML code segment. As related approach, mapping from XML to RDF is mentioned. RDF with OWL languages are also compared. The thesis concludes with grouped impressions of approaches. On the basis of these, new approach is recommended, which would eliminate biggest disadvantages met during the reviews of other approaches.
