92 STU Faculty of Informatics and Information Technologiesweb-based systems, where the content can be dynamically added orchanged and we have no content available in the design stage of theweb-based system. We introduce two methods falling within the scopeof data collection stage, a method for comprehensive logging of useractivity on the Web with preserved semantics, which combines clientside and server side logging into a stream of user events with clearlydefined meaning, and a method for capturing logs of “wild” Web surfingbased on a specialized proxy sever. The second group of methods,devoted to actual user model creation within an open corpus environment,consists of a method for user model inference based on rulesexpressing navigational patterns, a method for term-based open corpususer modeling, which can be applied to capture user’s interest acrossthe third-party web-sites and web-based systems. We proposed also amethod for finding relations between terms based on folksonomies,which supports our term-based user modeling approach. The proposedmethods were evaluated by means of software tools that were incorporatedin research projects on intelligent information presentation.Student name: Peter BartalosDegree program: Software EngineeringThesis title: Effective Automatic Dynamic Semantic Web Service CompositionSupervisor: Mária Bieliková, ProfessorDefended on: February 10, 2011Annotation: Web services are a popular technology used when diverse softwaresystem integration is in demand. The ability to make some functionalityavailable through the Web has inspiring consequences. One of theintensively researched areas is the study how Web services can beused to dynamically create a functionality, based on the actual requirements.The basic idea is that multiple Web services can be combinedtogether to form a composite service supplying more complexneeds. The composition is realized automatically, on the fly, based onthe actual goal. To facilitate this kind of Web service utilization, additionalmetadata depicting the functionality of single services is required.These metadata are provided in a form of semanticannotations. Our work deals with selected subproblems of the automaticdynamic semantic Web service composition. The sub-problemsinclude the proper description of the behavior of Web services, managementof the changes in the service environment, and handling multiplecomposition requests arriving continuously.Student name: Jozef TvarožekDegree program: Software EngineeringThesis title: Bootstrapping a Socially Intelligent Tutoring StrategySupervisor: Mária Bieliková, ProfessorDefended on: February 10, 2011Annotation: We present an approach for computer supported education in the formof a socially intelligent learning environment that is available online.It integrates problem solving and instructional materials into individualand group learning scenarios.
