Implementation of Algorithm for Visual Web Page Segmentation
Popela, Tomáš ; Burget, Radek (referee) ; Zelený, Jan (advisor)
Segmentation of WWW pages or page division on di erent semantics blocks is one of the disciplines of information extraction. Master's thesis deals with Vision-based Page Segmentation - VIPS method, which consist in division based on visual properties of page's elements. The method is given in context of other prominent segmentation procedures. In this work, the key steps, that this method consist of are shown and described on examples. For VIPS method it is necessary to cooperate with WWW pages rendering engine in order to obtain Document Object Model of page. The paper presents and describes four most important engines for Java programming language. The output of this work is implementation of VIPS algorithm just in Java language with usage of CSSBox core. The original algorithm implementation from Microsoft's labs is presented. The di erent development stages of library implementing VIPS method and my approach to it's solution are described. In the end of this work the work's outcome is demonstrated on several pages segmentation.

Proxy Server for Mobile Devices
Vašenka, Václav ; Chmelař, Petr (referee) ; Weiss, Petr (advisor)
This thesis should introduce principles of proxy servers. Main focus is on using proxy as a mediator between a web user, accessing the web from mobile devices and a web server. Next, this paper deals with web design and with aspects that have affect the speed and effectiveness of web page browsing via a proxy server. Moreover, the realization of such a system is described in this paper.

Web Page Segmentation Algorithms
Laščák, Tomáš ; Burgetová, Ivana (referee) ; Burget, Radek (advisor)
Segmentation of web pages is one of the disciplines of information extraction. It allows to divide the page into different semantic blocks. This thesis deals with the segmentation as such and also with the implementation of the segmentation method. In this paper, we describe various examples of methods such as VIPS, DOM PS etc. There is a theoretical description of the chosen method and also the FITLayout Framework, which will be extended by this method. The implementation of the chosen method is also described in detail. The implementation description is focused on describing the different problems we had to solve. We also describe the testing that helped to reveal some weaknesses. The conclusion is a summary of the results and possible ideas for extending this work.

Dynamic DOM Support in an HTML Rendering Engine
Kocman, Radim ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The aim of this work is to create an extension for rendering engine CSSBox. This extension will implement Document Object Model interface for the Client-Side JavaScript. The first part of this thesis describes the CSSBox project, the current state of JavaScript engines, Document Object Model used in web browsers and the final design based on Adapter and Abstract Factory patterns. The rest of the text describes implementation issues with the W3C DOM specification and compares the speed of this extension with web browsers.

Web Page Layout Facilities in JavaScript
T.Kovács, Gregor ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The aim of this work is to design and implement applications for the creation of web page layout facilities using JavaScript. The work includes the descriptions of the available methods of object positioning using the CSS given possibilities, the CSS 2.1 standard, and the difficulties of object positioning using CSS. Further, it includes the analysis of how the object placement is solved in the Java programming language using grid based layout managers GridLayout and GridBagLayout. Based on the obtained knowledge, designs are created for the solving of object placement in the creation of web pages using the grid principle. The object placement is solved by defining new HTML attributes for position determination, and also by creating a graphical editor for object placement. All the solutions are implemented using JavaScript.

RTF Document Processing Library
Šušlík, Martin ; Kreslíková, Jitka (referee) ; Burget, Radek (advisor)
The goal of this work is design and implementation of library for RTF processing. The library contains classes for conversion of RTF files to XHTML files. Implementation of library is made in Java programming language and it is tested by using proposed set of tests. Application interface of the library is a subset of the DOM standard and allows to manipulate with final XHTML document.
