Entity Knowledge Base Creation from Czech Wikipedia
Sychra, Martin ; Otrusina, Lubomír (referee) ; Smrž, Pavel (advisor)
The aim of this thesis is to propose and implement a system for an automatic extraction of named entities from Czech Wikipedia, to create a knowledge base consisting of these entities and to evaluate results of the created system. The first part explains basic notions of this field and discusses related work. The main part proposes several methods of extraction and details their implementation. The following types of entities are extracted: people, places, events and organizations. The final part of the thesis presents results, i.e., the success of the individual methods for each entity type and statistics on extraction of the individual entities in the whole Czech Wikipedia context.

Multivalued logic systems for technical applications
Turek, Vojtěch ; Druckmüller, Miloslav (referee) ; Martišek, Dalibor (advisor)
Velmi často je vyžadováno, aby automatizovaná zařízení byla jistým způsobem "inteligentní", tedy aby jejich řídicí systémy uměly emulovat rozhodovací proces. Tato diplomová práce poskytuje obecný formální popis vícehodnotových logických systémů schopných zmíněné emulace a jejich souvislost s teorií fuzzy množin. Jsou uvedeny způsoby vytváření matematických modelů založených na lingvistických datech. Dále se práce zabývá znalostními bázemi a jejich vlastnostmi. Součástí této práce je také počítačový program sloužící k tvorbě slovních modelů.

Expert systems
Veselovský, Michal ; Konečný, Pavel (referee) ; Dvořák, Jiří (advisor)
Expert systems (ES) are commercially one of the most succesfull use of artificial intelligence (AI) - since eighties of the 20th century. They are often used in medicine, industry, science, trade, banking etc. Expert system is a software using knowledge of human experts for solving very complicated tasks and problems, which would otherwise require participating or consultation of one or more specialists on these issues. This software simulates decision-making of human expert in solving complicated tasks, and tries to reach the most probable result, ideally same as the expert´s opinion. Typical feature of expert systems, differencing it from usual software, is separating of decision making engine (inference engine) and knowledge base – same expert system with different knowledge base may serve for different purposes. This feature is used for creating empty expert systems – shells. Other features, which may not occur at all ES, are ability to make decision with uncertainty, and ability to explain the decision. Goal of this work is to describe basic principles of ES, using freely available information sources, and then describe and analyze resources for creating of these systems, using mainly information from official web sites.

Petri nets for expert systems
Million, Pavel ; Pohl, Jan (referee) ; Jirsík, Václav (advisor)
Purpose of this master thesis is description of base parts of expert system with using Petri nets. Attention is mainly concentrate to knowledge base, way of storing knowledge. Next parts are describing main different between production base knowledge for planning or diagnostic expert system from Petri nets view. In this thesis conditions of using Petri nets and way of interpretation knowledge for inference mechanism in planning and diagnostic expert system are described. Using of high level Petri nets and language describing Petri nets structure and behaviour are demonstrated in next part of this thesis.

Internet Tools for Lifelong Learning in the IT Sector
Janková, Martina ; Jašek, Roman (referee) ; Roudný, Radim (referee) ; Slabý, Antonín (referee) ; Rais, Karel (advisor)
In the presented dissertation, there is, based on a given topic “Internet tools for lifelong learning in the IT sector”, expressed an appropriate coverage of created partial research tasks with an active solution of them at the Faculty of Business and Management, Brno University of Technology for branch Company Management and Economics, and that in accordance with the defined areas of research and publication activities. For systemic approach to the whole dissertation, it was defined area of theoretical perspectives and expressed methodology for addressing systemic models of education on Internet means and for that practical research work was chosen adaptable (“learning”) Company 1 as a reference (for solving individual practical research tasks) and a methodology of modern approach to modelling was created (“for modern management and information communication between systems”) and also modelling of a required adaptable (“directly also improving with modelling”) Internet (and intranet) environment of companies and its use in the process of lifelong learning of knowledge workers (“teachers”) of Company 1 and possible additional (“knowledge workers and users”) Company 2, 3, ..., m i.e. “businesses as other customers” and all that to actively create an adaptable and new space with the possible use of an evolutionary (“new and also modern and intelligent and self-learning”) means of information and communication technologies (ICT) both from the world and from the Czech Republic and especially new (and evolutionary perspective) Internet tools and resources for business management, lifelong learning in IT sector and necessary monitoring of demanded company's competitiveness operating in dynamically developing IT. By systemically solved modelling on computers, there is expressed an issue of appropriately selected internet tools in a competitive environment of companies, and also there is addressed by computer modelling a new approach to modelling leading to an anticipated modernization of modern electronic lifelong learning forms built on tools and resources of the Internet. The work also includes a creation of models on PCs allowing comparison of expected changes in competitiveness of companies reacting to the benefits of created methodology and that leads to an anticipated improvement in the quality of management and economics of companies in terms of relative improvement of their competitiveness. Solving of these modern issues is conducted based on an appropriate analysis of selected enterprises, corresponding to the solved topic and solved objectives of the work and also obtained information from publications in world information sources on the Internet and from virtual libraries of the world, publishing, seminars, proceedings and conferences. The results of system analytical approach to solving tasks and activities of the research work have been regularly published in articles of professional and peer-reviewed journals and also in conference contributions. In these research results, there is systematically expressed a new essence of solving interface of social and IT technical system with selected resources of internet tools for lifelong learning companies working in IT sector as a possible contribution into modern creation of self-learning organizations.
