Čižinská, Martina ; Palovská, Helena (advisor) ; Kosek, Jiří (referee)
The basis of my work represents a research focused on the problematic of native XML databases. The main goal is to draw comparison between the selected database systems in a sphere of user control and management of XML data. Database products are tested via XMark benchmark test using its XQuery queries and testing XML data. Final comparisons and recommendations for use are based on the concluding evaluation and findings. The results of research may improve orientation in solved problematics. They could help with the selection of a suitable database product to store XML data.

Indexing and searching XML documents with Lucene
Beránek, Lukáš ; Kliegr, Tomáš (advisor) ; Pinkas, Otakar (referee)
The creation of analytical report is a process in which we try to obtain and preserve the results of data mining tasks for further usage. Next step after the creation is to transform them into user friendly and accessible way that can be easily access for example as an online HTML document in the SEWEBAR project. The increasing number of resulting documents is the main reason of the need to possess means to search on structured date like XML documents that correspond with the PMML standard in which the reports are currently being saved. The main goal will be in stating available means for indexing and full text searching of XML documents targeted upon searching association rules that can be found in output documents produced by programs LISp-Miner or Ferda. After the initial analysis and assessment of the current state an extension for CMS Joomla! will be created in order to satisfy the need for indexing and searching indexed data. As source files for created Jucene extension we use analytic reports saved in the database of the Joomla content management system stored in PMML format. Stored PMML document will be simplified, optimized and transformed by means of an XSL transformation for better indexing possibilities in requested structure and with maintaining logical order of the document data mining task. Transformed document will then be inserted into the Zend Lucene document index. To achieve this in PHP environment the DOMDocument library will be used. Created workflow will supply user interface for work with indexed rules. Also it will provide the users with means for searching association rules based on user specified queries which can be processed by Zend Search Lucene framework. When rules that correspond to the user query are found the system will score the results and display them to the user. One of the goals is not only to create the Jucene component but also to give its users step-by-step guidance either they are the site administrators or ordinary visitors.

Essential tools for developing web applications
Ševčík, Petr ; Pinkas, Otakar (advisor) ; Chudán, David (referee)
This bachelor thesis is devoted to problems of creating web applications using XML files for data storing. The main mission of thesis is to demonstrate XML language usage in these applications and to introduce a reader with another important languages for development of these applications. This thesis is trying to offer a complex view of this problem. Because success of application largely relies on the fact how easily the applacation can be found by potential users of the web, the thesis describes how can be web sites indexed by search engines. There are two main parts of this bachelor thesis: teoretical and practical. The first chapter describes HTML language with accent on his features that can be used for cooperation with web applications. The second chapter is devoted to XML markup language. Third chapter is about Dublin Core metadata standard which can be used with web applications to ease searching of electronical sources. The fourth chapter describes indexing of web pages by search engines and the following fifth chapter describes advanced searching with search engine Google, that can be used for detection if search engine optimization was successfull and if web page is findable. The sixth chapter dedicated to practical part of this thesis. This part describes developed web application programmed in PHP language. This application works with XML file via DOM and SimpleXML interfaces. Interfaces are compared to each other. This chapter also offer some guides describing how to implement some usefull functions in web application.

Problems of information search on the Internet
Janů, Tomáš ; Sklenák, Vilém (advisor) ; Šubrta, Václav (referee)
This thesis adverts to the inadequacies and impediments which can be met by an ordinary user of the internet when searching for information. The process of searching itself represents an interaction between the request given by a user and the result displayed by a search engine. The result might be in a form of URL address of a concrete web page, picture, product, location etc. Some of the problems, which are described in detail in the thesis, are for example relevance and freshness of the search result, separation of global and local result, spam in the results or problems connected to the searching in the online maps. There is an emphasis on the local market, respectively on the Czech user, in the thesis. Furthermore, it focuses on the freshness of all data and on a practical sample in a picture form. The important data and statistics are recorded in the well-arranged tables and graphs. Among others, many interesting information and observations can be found in the thesis. These information and observations are marked with the blue arrow (->).
