WordNet Database User Interface Innovation
Kopřiva, Adam ; Jaša, Petr (referee) ; Chmelař, Petr (advisor)
This thesis considers innovations of graphical user interface for JWord 3.0. It's a program, which works with electronic lexical database of English - WordNet. The words in this database aren't sorted in the alphabetical order like in usual dictionaries, but they are grouped to synonymic groups. These groups are then connected with different semantic relations. During the implementation design I have focused mainly on the speed of searching for informations about the entered word. This lead to the change of searching engine from searching in files to querying database. The resulting program is composed of two parts - program and graphical user interface. Program interface works with MySQL WordNet 3.0 database. User interface then shows meanings of the entered word and relations to other words (synonyms, antonyms, hyponyms, hypernyms).
Searching Semantically Annotated Texts
Grešová, Katarína ; Smrž, Pavel (referee) ; Dytrych, Jaroslav (advisor)
This thesis deals with the issue of semantic searching over indexes of big text data. The aim of this thesis is to design and implement a search engine with web user interface enabling dynamical configuration of access to indexes and editing annotations in the text. The thesis analyzes the current search engine solution and its shortcomings, which results in a specification of requirements for a search engine that is suitable for common use and fulfils the potential of all search engine related tools. The thesis also describes the design, implementation and testing of the resulting system, which also includes an extension in a form of global constraints, which increases the accuracy of the requested search result description.
RDF Repository in PHP
Raška, Jiří ; Chmelař, Petr (referee) ; Burget, Radek (advisor)
This Bachelor Thesis describes a problem of design and implementation a RDF repository in PHP. This thesis solves storing data model RDF in relational database and solves implementation of subset query language SPARQL. Part of this thesis are performance and functional tests with implemented RDF repository.
Genealogic Semantic Wiki
Brychová, Jana ; Smrž, Pavel (referee) ; Schmidt, Marek (advisor)
This thesis project is about possibilities of storing genealogic data in different formats and based on the results it suggests data format which can be used consequently as a source for the vizualization by semantic web. In the scope of the project there is a genealogic application implemented for KiWi platform. This application enable visualization of designed format using prefuse technology. There are basic and aslo some other usefull information about the basic technologies of the semantic web like RDF, XM, ontology, OWL language stated in the document.
Generating Program Code from Ontology Definition
Svetlík, Tomáš ; Hynek, Jiří (referee) ; Burget, Radek (advisor)
This master thesis deals with the process of generating source code from ontology definition. It is advantageous to have ontologies in the source code representation, when developing ontological applications. This source code expresses ontology classes and properties. The main goal of this thesis is to develop an implementation of the tool that uses this process. The thesis describes the design, implementation and testing of this tool. The result is a fully functional source code generator. It is able to generate Java or Python source code. Functionality and reliability were evaluated according to testing with set of actually used ontologies.
Semantic Web - Tutorial and Examples
Hanyáš, Petr ; Chmelař, Petr (referee) ; Očenášek, Pavel (advisor)
This thesis deals with design and realization of interactive presentation consists of tutorial which topic is "Semantic Web" and related demonstration examples with comments. Thesis is also consists of users' and commentaries' administration, testing system with random generation of questions, fulltext search engine and description of ontology editors. The aim of whole thesis is to create educational materials with a possibility of checking reached level of knowledge. Motivation for making this thesis was lack of complete materials in Czech language dealing with this problem. My aim was to create these kinds of materials so it can be intelligible to wide range of readers.
Ontology Based Information Extraction from the Web
Buba, Vojtěch ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The main aim of this thesis is an extraction of information from web based on conceptual modeling with ontology. The main goal of this thesis in question is implementation of a tool, which process input ontology and enable additional editing through graphical user interface. Readers of this thesis will be introduced with languages for writing ontologies, for example RDF, RDFS or OWL. Two extraction methods which use ontologies to describe extracted informations are also explained. Final solution is designed to consider all needs of extraction task defined by Ing. Radek Burget Ph.D. Output of this tool is definition of extraction task compatible with solution FITLayout, being developed at FIT BUT.
Visual Design of Ontologies for Semantic Web
Procházka, Jiří ; Mrnuštík, Michal (referee) ; Šperka, Svatopluk (advisor)
Tato práce popisuje návrh a implementaci vizuálního editoru ontologií pro Sémanticý web, založený na RDF modelu, soustředící se na přehlednou kompaktní vizualizaci ontologií, jejich selektivní zobrazení z různých aspektů, a jejich tvorbu s rozšířítelností v nabídce ontologických jazyků.
Comparison of RDF Databases
Chatrný, Jakub ; Burget, Radek (referee) ; Milička, Martin (advisor)
The goal of this thesis is compare of several RDF stores Blazegraph, Jena TDB and Stardog. Design of test suites is based on existings benchmarks. In the designed test suites are monitored execution time and number of results. The testing criteria of stores also include the time required to create persistent store and its size. All tested stores and the program for testing itself are implemented in Java.
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.
