Framework pro transformaci z jazyka PURO do ER modelů v jazyce OntoUML

During process of ontology creation in OWL is common to work just with source data. Although much efficient approach is to create implementation independent model of real situation which can be implemented for example in PURO language. Ontological engineers have a chance to think about the situation more deeply, be aware of every entity and do not forget to express any relationship between them. As PURO alternative OntoUML can be used which has many more expressive abilities. Handle OntoUML could be challenging for inexperienced users because of its complex syntax. In both cases models can be automatically tranform to OWL.We can also combinate both model languages during ontology creation. The first model should be just generalization of whole situation it should be created in model language with less complex syntax, PURO language is ideal in this case. After that the more complex and restrictive model of reality is created for this purpose in OntoUML. The final model can be used for automatic transformation to OWL in another tool. Models can be also used as a guideline for ontology users.The main goal of this thesis is to design and implement prototype of application which should guide the user through process of transformation from PURO to OntoUML. The application should simplify whole transformation and should help to the user to do not make syntax mistakes. The process of transformation is ruled by externally defined rules which are independent from the program implementation.In the first part of the thesis is an introduction of semantic web and modelling languages. In the next part the design of the application is described includes design of a user interface and design of an algorithm. Next the implementation of functions is described and at the end the successful evaluation is mentioned.
