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.

Computer analysis of medical image data
Krajčír, Róbert ; Šmirg, Ondřej (referee) ; Uher, Václav (advisor)
This work deals with medical image analysis, using variety of statisic and numeric methods implemented in Eclipse and Rapidminer environments in Java programming language. Sets of images (slices), which are used here, are the results of magnetic resonance brain examination of several subejcts. Segments in this 3D image are analyzed and some local features are computed, based on which data sets for use in training algorythms are generated. The ability of successful identification of healthy or unhealthy tissues is then practically tested using available data.

Interfaces for Faceted Search in Indexed Wikipedia
Cilip, Peter ; Otrusina, Lubomír (referee) ; Smrž, Pavel (advisor)
Main aim of this thesis is to study existing systems of faceted search and to design own system based on faceted search in the index of Wikipedia. In this thesis we can meet with existing solutions of faceted search. From mistakes and failures of existing solutions was designed our own system, that is output of this thesis. Designed system is described in way of design and implementation. Product of thesis is application and graphical interface. Application interface can be integrated into existing informational system, where it can be used as multidimensional filter. Graphical interface provides option how can application interface be used in real system. System was created focusing on usefullness and simplicity, for using in existing information systems.

How Can We Google More Effectively?
Kolesárová, Lucia ; Shapiro, Irina (referee) ; Macháček, Mikuláš (advisor)
Current Google provides almost all type of information in a similar way - list of web pages. But Each information needs a different manner of mediation. A different way of visualisation. Therefore I decided to create Google of tomorrow. I am focused on a new way of spreading information and communication. I created new tools which help to achieve this vision. These tools operate in augmented reality. My diploma is mainly work of design fiction and information design. I use extrapolation to create possible future scenarios. Future abilities of Google tools are extrapolated from its current technologies.

Searching algorithms
Ďuriš, Martin ; Šeda, Miloš (referee) ; Dvořák, Jiří (advisor)
The thesis describes and analyzes selected searching algorithms for single dimensional array. Algorithms are analyzed mathematically and graphically. Mathematical analysis is based on analysis of average amount of performed comparisons required for the final result and literature review. Graphical analysis is based on multiple examinations of selected searching methods with randomly generated single dimensional arrays. The graphs show dependency of elapsed searching time of successful and unsuccessful searching trial on the size of single dimensional array. The results establish the binary searching algorithm as the fastest one of the selected searching algorithms.

Searching in Speech Data
Fapšo, Michal ; Černocký, Jan (referee) ; Szőke, Igor (advisor)
This thesis describes a designed and implemented system for efficient storage, indexing and search in collections of spoken documents that takes advantage of automatic speech recognition. As the quality of current speech recognizers is not sufficient for a great deal of applications, it is necessary to index the ambiguous output of the recognition, i.\,e. the acyclic graphs of word hypotheses -- recognition lattices. Then, it is not possible to directly apply the standard methods known from text--based systems. This paper discusses an optimized indexing system for efficient search in the complex and large data structures which are the output of the recognizer.

Munis Instant
Tomasy, Lukáš ; Hoksza, David (advisor) ; Kopecký, Michal (referee)
Title: Munis Instant Author: Lukáš Tomasy Department: Department of Software Engineering Supervisor: RNDr. David Hoksza Supervisor's e-mail address: hoksza@ksi.mff.cuni.cz Abstract: Quick searching of information was always very important for people. Today, in era of internet and information system it is perhaps even more important. Therefore software engineers around the globe try to develop as sophisticated search system as possible. Project Munis Instant should join this initiative and should provide intelligent searching of informations based on instantly displaying relevant data from the database alongside with typing. Program is being developed as a library written in .NET platform and can be used over any database supported by .NET (OldDbProvider). The main goal was, the should be independent on database system or information system. Keywords: Searching, information system, .NET
