Pekař, Tomáš ; Kouřil, Jan (referee) ; Smrž, Pavel (advisor)
The aim of this work is to design and implement a system for duplicate text identification. The application should be able to index documents and also searching documents at index. In our work we deal with preprocessing documents, their fragmentation and indexing. Furthermore we analyze methods for duplicate text identification, that are also linked with strategies for selecting substrings. The thesis includes a description of the basic data structures that can be used to index n-grams.

Repository for results of association rules data mining tasks in SEWEBAR project
Marek, Tomáš ; Šimůnek, Milan (advisor) ; Svátek, Vojtěch (referee)
This diploma thesis aims at design and implementation of I:ZI Repository application. I:ZI Repository application provides management of data mining tasks and theirs results repository and functions for search in this repository. I:ZI Repository is a REST API build on top of Java EE technology, Berkeley XML database is used for storing data mining tasks. I:ZI Repository application was created based on XQuery search application. The application has completely new structure compared to XQuery search application, all functionality of XQuery search application is present in I:ZI Repository application. Possibilities of using more general search query was added into I:ZI Repository application as well as fuzzy approaches for searching and possibility of clustering search results. Enhanced logging of application activities aimed at logging incoming search queries and outgoing search results is a part of implementation. Results of application testing are included as well.

Potužáková, Karolína ; Burkoň, Lukáš (advisor) ; Vidim, Jaroslav (referee)
The purpose of the thesis is to explain off-page optimization. In the introduction, the reader learns important terminology. Ways of improving off-page factors are divided into two main categories. Active linkbuilding, i.e. active acquisition of backlinks, and passive linkbuilding, when people link to the web themselves e.g. on the basis of good contents. The next part mentions a tool suitable for administration of SEO activities. The theoretical part is used in the subsequent web analysis, where off-page factors of the web are evaluated and their quality is compared with competitors. The final part of the thesis contains recommendations for a particular web regarding off-page factors. The reader who has read this thesis should be able to distinguish good off-page optimization and to understand how the web visit rates can be improved by means of backlinks.

Digital documents library
Bouda, Petr ; Šlajchrt, Zbyněk (advisor) ; Pecinovský, Rudolf (referee)
The goal is to program an application that allows managing and searching electronic documents. Applications must provide a record of documents over the web. The application can record as individual documents, and documents that are packaged in ZIP archive. We can assign metadata using inserting or updating to individual documents. Application can search for documents using the full-text searching or searching based on their metadata. After searching you can export a single document or group of documents in a ZIP archive. Digital library must have an interface for communication with the library system of third parties. Using this interface, you can use the search functionality of the application and the subsequent return of results. Another use interface is information the library system with new digital increments.

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.
