Mining and management of data on conferences and workshops
Pilát, Martin ; Žemlička, Michal (advisor) ; Eckhardt, Alan (referee)
The goal of this work is to create an application, which would help its users to be acquianted with huge amounts of information on conferences, workshops, congresses, and Symposiums. The number of shown events can be reduced by the use of an advanced system of user-defined filters. The application contains a sophisticated system of user privileges and provides support for creating personal and group calendars. An important part of the application is a module for automated retrieving of information from incoming e-mail messages. This module uses a simple pattern matching for extracting deadlines, topics, name, and other important data on a particular conference. These patterns are stored in a hand-crafted dictionary. The accuracy of this module is about 80% for mining the dates and about 70% for mining other types of data.

Smrčka, Zdeněk ; Vojtáš, Peter (advisor) ; Eckhardt, Alan (referee)
Title: Acquiring user preferences for e-shop Author: Zdenek Smrcka Department: The Department of Software Engineering Supervisor: prof. RNDr. Peter Vojtáš, DrSc. Abstract: The goal of this thesis is to create e-shop /in medical domain (sector), but useable in other domains (sectors)/. We use implicit metod for acquiring user preferences. By the help of this method the products are ordered from most preferred to less preferred for registered user. In case that user will choose some interesting category of products, then products are listed from maximum to less preferred in that category. It creates feedback about popularity of products for individual users and the producer gets information about interest of products in the market place and administrator can change positions of products in e-shop base on popularity. Keywords: user preferences, internet shop, user's favorite's products

Web Search Engine
Tamáš, Miroslav ; Galamboš, Leo (advisor) ; Eckhardt, Alan (referee)
Egothor is high-performance, full-featured Open Source text search engine written entirely in Java. It is technology suitable for nearly any application that requires full-text search, especially cross-platform. The aim of this work is to implement a complete web search gate of Egothor 2 and a respective administration interface (e.g. reindexing, filtering actions). It must be possible to manage several indices without switching them off-line during the service.

Mathematics on Internet
Dózsa, Martin ; Holub, Viliam (advisor) ; Eckhardt, Alan (referee)
The aim of this work is to create an easy-to-use mathematical tool, mainly for students specialized at mathematical education. UniMaxima focuses on calculations within the frame of mathematical analysis and (especially linear) algebra. It calculates derivatives, definite and indefinite integrals, decomposition to partial fractions, Taylor-series, sums, limits, matrices, eigenvalues, eigenvectors and determinants. It is also possible to plot functions of one or two variables. The advantage of UniMaxima is simple use, there is no need to install: it is enough to visit the project's website (with Firefox 3.0+) and input the formulae.

User preferences in the domain of web shops
Peška, Ladislav ; Vojtáš, Peter (advisor) ; Eckhardt, Alan (referee)
The goal of the thesis is first to find available information about user preferences, user feedback and their acquisition, processing, storing etc. The collected information is then used for making suggestions / advices for the creating an recommender system for the web shops (with special emphasis on implicit feedback). The following chapters introduces UPComp - our solution of the recommender system for the web shops. The UPComp is written in the programming language PHP and uses MySQL database. The thesis also includes testing of the UPComp on real-user web shop sites slantour.cz and antikvariat-ichtys.cz.

Induction of user preferences in semantic web
Dvořák, Tomáš ; Eckhardt, Alan (advisor) ; Dokulil, Jiří (referee)
This thesis deals with the induction of user preferences. In its first part it surveys the field of user preferences on semantic web. Subsequently, it describes various methods of data collecting. In the part concerned with inductive methods the paper focuses mainly on collaborative filtering and decision trees. Many value models and preference relations belong among the most important of the described models. The aim of the thesis is neither to provide a complete enumeration in its individual parts, nor to render as detailed view as possible. Rather, it aims at gaining a basic outline of this broad theme. The second part of the thesis pursues the description of the implementation of a testing framework which enables the easiest testing of inductive methods without the knowledge of the inner structure of the framework. The final part describes the technique and results of the testing of decision trees and collaborative filtering on databases NetFlix and MovieLens. Here the framework described in the second part of the paper has been used as a testing tool.
