The use of linked open data for strategic knowledge game creation
Turečková, Šárka ; Svátek, Vojtěch (advisor) ; Zeman, Václav (referee)
The general theme of this thesis was the use of linked open data for a creation of games. This thesis specifically addressed the issue of usage of DBpedia for automatic question generation suitable for use in games. Within that are proposed suitable ways of selecting wanted objects from DBpedia and ways of obtaining and processing relevant information from them. Including a method for estimating renown of individual objects. Some of methods are then applied to create a program for a question generation from the data obtained through DBpedia during the run of the application. The real possibility of using these questions generated from DBpedia for gaming purposes is subsequently proved by the design, prototype and tests of a knowledge strategic multiplayer game. The paper also summarizes all the major issues and possible complications from using the data obtained through DBpedia or DBpedia Live endpoints. Current challenges and opportunities for mutual utilization of games and LOD are also briefly discussed.

Semantic support in CMS Drupal
Ivančo, Daniel ; Svátek, Vojtěch (advisor) ; Hazucha, Andrej (referee)
Aim of this diploma thesis is to map semantic features of CMS Drupal version 7. The goal of the first part of this work is to theoretically describe semantic web problematic and CMS Drupal. The second -- practical part of this work maps in details all the features of semantic web, which are supported by described CMS Drupal. These semantic features are mapped in two different points of views -- implementation and functional. Main contribution of this work is the method used to map these features. It's based on Drupal plugins code modification and revision in order to draw or demonstrate these features, which are not necessarily completely documented or functional. Furthermore all of these features are demonstrated on examples created as a part of this thesis. Finally the last part of this work compares these mapped features to similar CMS systems.

Repurposing Grey Literature - Linking Research Data to Full-Text Publications: Some Preliminary Results
Farace, Dominic
This presentation deals with the research design and preliminary results of EPP, an Enhanced Publications Project carried out among a pool of over 280 authors in the International Conference Series on Grey Literature. In a way, this project seeks to circumvent the data vs. documents camp in the grey literature community by way of a middle ground provided through enhanced publications. Enhanced publications allow for a fuller understanding of the process in which data and information are used and applied in the generation of knowledge. The enhanced publication of grey literature precludes the idea of a random selection of data and information, and instead focuses on the human intervention in data-rich environments. Enhanced publications inherently contribute to the review process of grey literature as well as the replication of research and improved visibility of research results in the scholarly communication chain.

Mapování ontologií a jeho vyhodnocování pomocí vzorů
Zamazal, Ondřej ; Svátek, Vojtěch (advisor) ; Vacura, Miroslav (referee) ; Pokorný, Jaroslav (referee) ; Štuller, Július (referee)
Ontology Matching is one of the hottest topic within the Semantic Web of recent years. There is still ample of space for improvement in terms of performance. Furthermore, current ontology matchers mostly concentrate on simple entity to entity matching. However, matching of whole structures could bring some additional complex relationships. These structures of ontologies can be captured as ontology patterns. The main theme of this thesis is an examination of pattern-based ontology matching enhanced with ontology transformation and pattern-based ontology alignment evaluation. The former is examined due to its potential benefits regarding complex matching and matching as such. The latter is examined because complex hypotheses could be beneficial feedback as complement to traditional evaluation methods. These two tasks are related to four different topics: ontology patterns, ontology transformation, ontology alignment evaluation and ontology matching. With regard to those four topics, this work covers the following aspects: * Examination of different aspects of ontology patterns. Particularly, description of relevant ontology patterns for ontology transformation and for ontology matching (such as naming, matching and transformation patterns). * Description of a pattern-based method for ontology transformation. * Introduction of new methods for an alignment evaluation; including using patterns as a complex structures for more detailed analysis. * Experiments and demonstrations of new concepts introduced in this thesis. The thesis first introduces naming pattern and matching pattern classification on which ontology transformation framework is based. Naming patterns are useful for detection of ontology patterns and for generation of new names for entities. Matching patterns are basis for transformation patterns in terms of sharing some building blocks. In comparison with matching patterns, transformation patterns have transformation links that represent way how parts of ontology patterns are transformed. Besides several evaluations and implementations, the thesis provides a demonstration of getting complex matching due to ontology transformation process. Ontology transformation framework has been implemented in Java environment where all generic patterns are represented as corresponding Java objects. Three main implemented services are made generally available as RESTful services: ontology pattern detection, transformation instruction generation and ontology transformation.

SPARQL plugin for Ontopia Knowledge Suite
Ovčáčík, Vlastimil ; Kliegr, Tomáš (advisor) ; Svátek, Vojtěch (referee)
Reader of this bachelor thesis will familiarize with two technologies of semantic web -- Topic Maps and RDF. In the first half of this document we can find principles, history and thoughts on near future of both technologies. There are explained necessary principles of both standards. Emphasis is placed on query languages SPARQL and TMQL. Object of this thesis is understanding differences and mutual aspects of both Topic Maps and RDF. This understanding is key for finding interoperability between these two technologies on semantic web. The second half of this thesis is aimed on implementation of sparql4ontopia - a plugin for Ontopia Knowledge Suite, which enables quering topic maps with SPARQL. This plugin utilizes Sesame project for SPARQL query evaluation and Nikunau tool from SesameTM project for mapping SPARQL on Topic Maps Data Model. Possibilities and limitations of this plugin are described. There is also description of sparql4ontopia development and implementation. Last chapter shed light on SPARQL endpoint and possible way of implementation into Ontopia Knowledge Suite.

Support of Semantics in CMS Drupal
Kubaliak, Lukáš ; Svátek, Vojtěch (advisor) ; Hazucha, Andrej (referee)
The work concern about the support of semantics in known content managing systems. It is describing the possibilities of use for these technologies and their public accessibility. We find out, that today's technologies and methods are in the state of public inducting. In the question of semantic support in CMS Drupal we developed a tool for extending its support of semantic formats. This tool allows CMS Drupal to export its information in a Topic Maps format. For this it uses the XTM file.

Metadata and searching information on the Internet
Hlaváčová, Tereza ; Sklenák, Vilém (advisor) ; Pinkas, Otakar (referee)
The aim of this work is to analyze the relationship of metadata and searching on the Internet. In the first part are presented metadata, namely meta tags, metadata schemas and two related projects - digital libraries and the Semantic Web. In the second chapter is introduced the history and development of the Internet search engines. Two search engines are analyzed in detail: Google and Seznam - especially their history, development and how they evaluate pages. The last part is devoted to the summary of the importance of metadata for searching on the Internet and possible future development of digital libraries and the Semantic Web.

Web interface for ontology similarity measures
Pichl, Ota ; Zamazal, Ondřej (advisor) ; Svátek, Vojtěch (referee)
Semantic Web is one of the most recent topics on the internet. The idea of Semantic Web is associated to informatics ontologies which can provide features for description of web knowledge. Ontologies than bring the feature of semantic annotation for data and knowledge on the internet. This work is focused on comparison of ontologies and determination of their similarity or dissimilarity. Determination of these similarities can be made with various types of methods like vector space measures or collection measures. It is appropriate to implement these methods due to problems and uncertainties which ontologies can bring. Ontology independence is one of the basic characteristics (open world assumption) and because of independence there can appear certain conflicts if exist two ontologies describing the same part of reality. There can be a problem when these two ontologies describe the same entity but with different label or in different structure. Nevertheless there are many other reasons for making these comparisons e.g. extension of semantic search engines or searching for similar ontologies which could be joined together. Solution of this problem can be found in ontology similarity measures. Currently there is no application like this which would provide methods for ontology measures. The main goal of this bachelor thesis is to create a web interface which will provide essential methods for determination of ontology similarity.
