TRECVid Search Information Retrieval
Čeloud, David ; Mlích, Jozef (referee) ; Chmelař, Petr (advisor)
The master's thesis deals with Information Retrieval. It summarizes the knowledge in the field of Information Retrieval theory. Furthermore, the work gives an overview of models used in Information Retrieval, the data and the actual issues and their possible solutions. The practical part of the master's thesis is focused on the implementation of methods of information retrieval in textual data. The last part is dedicated to experiments validating the implementation and its possible improvements.

Information Retrieval in Czech Wikipedia
Balgar, Marek ; Bartík, Vladimír (referee) ; Chmelař, Petr (advisor)
The main task of this Masters Thesis is to understand questions of information retrieval and text classifi cation. The main research is focused on the text data, the semantic dictionaries and especially the knowledges inferred from the Wikipedia. In this thesis is also described implementation of the querying system, which is based on achieved knowledges. Finally properties and possible improvements of the system are talked over.

Methods of Searching in Large Dat Sets
Húsek, Dušan ; Pokorný, J. ; Snášel, V. ; Řezanková, H.
The lecture digest present formal methods used in the area of information retrieval intent on large data collections. Data collections have increased rapidly in last decade so new methods based on statistics, linear algebra, neural network etc. can be used. Generally, we can image processing a large data collection placed in the highly dimensional space. The most important point during processing these data appears reduction of dimensionality.
