Uživatelské rozhraní systému pro odhalování plagiátů

Abstract

This thesis describes development of a web application that provides graphical user interface of a plagiarism detection system. The aim of this thesis is design and implementation of the web application. The implemented system provides plagiarism checking for PDF documents and source codes written in virtually any programming language. At the same time, the system was specifically designed to allow users to create collections of files and perform plagiarism checks among uploaded files of these collections. Text annotations were used to highlight plagiarized portions of PDF documents, which are available in PDF viewing programs. Using text annotations, plagiarised text can be highlighted directly in PDF documents. Similar type of highlighting is also applied for source codes. In this thesis, experiments are performed on a larger collection of thesis written by students of the Computer Science Department.
