In this thesis, a tool to visualize duplicate parts in a series of given documents is developed. Text duplicates are very common nowadays in all fields. This behavior severelyharms the rights of the original authors though it facilitates the work of those whocopy from them. Effective legal measures have been taken when it comes to copyrightissue. An increasing large number of people have paid serious attention to what theywrite when they refer to other people's works. Although references are properly madeby many who admire and respect others' achievements, plagiarism takes place all thetime. Therefore, an intuitive way of visualizing duplicate parts is needed so thatpeople can easily grasp the purpose and decide the legality of those duplicates. Whenit comes to computer science, software clone is very typical phenomenon amongdifferent development groups or even within one group. Since a piece of softwareusually have its hierarchy, it is also interesting to group members when they do aclone detection of their own or other software. For example, if a good overview of thehierarchies is provided in a tree representation, one can easily locate the clones of aparticular node in other trees. More interaction techniques can allow concrete codeaccesses through double clicking on a highlighted node. To visualize duplicate parts in a nice and intuitive way, a visualization tool isdeveloped for this thesis project. By the time it is done, the following features shouldbe fulfilled. First, the tool can visualize similar or identical parts given a data set.Second, hierarchies of those files can be demonstrated with proper layout. Third, theuser can manipulate the data items on the screen in order to get a better insight of thedata set and help with analysis tasks. Forth, different levels of abstraction areprovided so that the user can either get an overview of all the files or specificallycheck the duplicate parts in the documents of interest. / Visualization of Text Duplicates in Documents

Master of Science / Department of Computing and Information Sciences / Xinming Ou / Attack graphs present a visual representation of all the potential vulnerabilities and attack paths in a network. They act as a vital security tool in finding the critical attack paths in the enterprise wide networks. Generated attack graphs for complex networks present thousands of attack paths to visualize and represent to the end user. Enhancing the visualization of attack graphs by adding user interactivity will greatly improve in analyzing attack graphs and identifying the critical attack paths in the enterprise network. The layout of the attack graph can be adjusted to represent the layout of the real world enterprise network. Adding user interactivity to attack graphs is done using Prefuse, a software framework written in Java for information visualization. Prefuse is flexible and got the ability to render large amounts of data in an efficient manner. The visualization framework for the attack graphs provides a GUI tool for interacting with attack graph. The framework is a layered architecture with two important layers, the static layer and the dynamic layer. The static layer translates the attack graph trace generated from MuLVAL into a standard graphviz dot language descriptive file. The dynamic layer translates the graphviz dot file into a graph object that can be interpreted and visualized using the prefuse software framework. Preliminary result in this work has been published in [19].

Baigiamajame magistro darbe pateikti praktiniai sprendimai, leidžiantys efektyviai rasti, išgauti ir vizualizuoti tinklapių medinę struktūrą. Tam yra sukurtas vizualiai tinklapių struktūros analizei atlikti skirtas instrumentas. Darbo tikslui pasiekti atlikta mokslinio potencialo analizė, parinkti efektyvūs metodai ir papildyti, atsižvelgiant į sprendžiamą darbo mokslinę ir praktinę problemą. Praktiniame darbe panaudojant class menu artumo bei urlmetodus ir taikant Prefuse vizualizaciją sukurtas instrumentas, leidžiantis ženkliai pagerinti svetainės navigaciją, struktūrą bei patobulinti svarbiausios informacijos pateikimą lankytojui. Gauti rezultatai leidžia efektyviai analizuoti, kurti, plėtoti ir vertinti tinklapių medinės struktūros navigaciją, tinklapio elementų ryšius ir vizualizacijos procesą. / This Master‘s thesis is contemporary and relevant as more efficient and convenient control of sitemap navigation and visualization is beneficial both to the user and creator of such systems. A simpler, faster sitemap, more effective visualization and more convenient structural menu are comprehensively valuable for website users. Therefore the object of this thesis is the creation of the tool which would ensure the visual analysis of site map. This Master‘s thesis contains practical solutions how to make sitemap data extracting, filtering and rendering more effective. The goal of this thesis is to create a tool, ensuring a more efficient sitemap data extracting, filtering and visualization. Therefore to achieve such goal, author forms the following tasks: to research and detect most efficient methods of work; to create an individual method for website sitemap extracting and filtering after applying class menu and url methods and also modifying them with classification and consolidation methods at first; successfully visualize data with the use of created tool. The tool, which improves website map filtering, extracting and rendering is created in the practical part of thesis by applying methods and Prefuse instrument. Obtained results allow us to upgrade and develop website navigation process, through association and visualization information even more efficiently. This project is implemented with JAVA, Python languages. „Microsoft Office Visio 2003“ is used for representation... [to full text]

This thesis project is about possibilities of storing genealogic data in different formats and based on the results it suggests data format which can be used consequently as a source for the vizualization by semantic web. In the scope of the project there is a genealogic application implemented for KiWi platform. This application enable visualization of designed format using prefuse technology. There are basic and aslo some other usefull information about the basic technologies of the semantic web like RDF, XM, ontology, OWL language stated in the document.
