Distributed Information System Based on Semantic Technology
Havlena, Jan ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
This master's thesis deals with the design of a distributed information system, where the data distribution is based on semantic technologies. The project analyzes the semantic web technologies with the focus on information exchange between information systems and the related terms, mainly ontologies, ontology languages and the Resource description framework. Furthermore, there is described a proposal an ontology which is used to describe the data exchanged between the systems and the technologies used to implement distributed information system. The most important of them are Java Server Faces and Sesame.

Ontology-Based Content Management System
Čekan, Ondřej ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
This thesis deals with the analysis, design and implementation of a system based on semantic technologies and ontology languages. There is described the semantic web and its concept, technology of semantic web especially RDF and OWL and the ability to view on the Web. Another part of this work treats with the specification, analysis, design actual implementation of the system, which processes the ontology and allows users to create individual depending on the definition of the ontology. The created content is presented on the Web annotated. The result of this work is the demonstration application.

Hodnocení sémantických aplikací pro podnikové prostředí

Broader and broader areas of application deployment are covered by semantic technologies recently and in the meantime their scope is increasing constantly. The possibilities of semantic applications are now so vast that they cannot be judged as a single market segment any more. The business skepticism that arises due to the uncertainty of investments in such technologies is only augmented by these differences and picking up on that this thesis concentrates on the aspects that can enable and evaluate not only the economic efficiency of engaging the semantic technologies in a business environment but also the effectiveness of doing so. This work concentrates on the ways of how to prove the differences amongst semantic applications, define their distinct segments based on use-case, and subsequently identify their Critical Success Factors and evaluate them against the real conditions of the applications' deployment with the participation of people involved in their development. Following the results of these interactions this thesis presents an innovative approach that enables to construct models for judging the maturity of enterprises for the deployment of the respective applications including the actual construction of these models for all the identified applications' use-cases segments. Moreover, in a later part of the work the evaluation using these models is demonstrated on AQUA application (outcome of a project the author did personally partake in) along with sketching additional specifics that may help the timely assessment of semantics in certain cases. The results presented in later chapters are supported by the underlying background researches in the fields of Semantic Technologies and IT assessment both of whose state-of-the-art methods are described here. Usability of the current standardized methods (such as those used in COBIT) for assessing semantic applications is also considered with respect to the lack of other best practices in business deployment of semantics.

Using semantic technologies in markup languages
Štencek, Jiří ; Nekvasil, Marek (advisor) ; Kliegr, Tomáš (referee)
This bachelor thesis analyzes the use of semantic technologies in the field of today's web portals. The aim is to map the major web servers and services. Work on the contrary seek cover all sites (blogs, corporate sites, etc.) that use semantic technologies, as it had almost no meaningful value. Contribution of this work should be an analysis of the implementation of semantic technologies on the Internet. This should show how much vision of the Semantic Web expands. How many web sites use this technology. Web sites that we use every day and which offer capabilities and features that we might not even know. Other benefits could be for example: extending the use of Semantic Web tools (Operator plugin, Semantic Radar), information awareness among Internet users who have never heard about this term. In other hand, it could be a basis to further and more detailed mapping of semantic sites. For example, statistically-oriented work on the utilization rates of ontological dictionaries. The work begins with an introduction to the world wide web as a beginning to the present, outlining the basic ideology WWW. Show us the pitfalls of the current WWW and its possible further development line. Chapter entitled Understanding the Semantic Web describes the basic building stones and architecture of this vision. Describes the framework RDF, ontology, and not forget the section on the safety of the Semantic Web. With this knowledge we have chapter Integration semantics on the current WWW to learn about options, where to find the necessary metadata and related principles of Linked Data. metadata to (X) HTML. More specifically, we describe microformats, RDFa and the eRDF. Conclusion chapter makes the comparison of these technologies and and show us practical examples of their implementation. The last chapter, which is called Analysis of the use of knowledge technologies now brings you an overview of the servers that use one of the above technologies. Describes the open source database, semantic search engines, ontological dictionaries and finally community and information portals. The results of the present chapter is a summary of the implementation and reflection on the real benefits and possible incentives Semantic Web.
