Podobnost softwarových artefaktů

Abstract

This thesis deals with the plagiarism of source code. The theoretical part of the thesis describes plagiarism in general, provides its forms, types and examples. The part of theoretical analysis, which is located in the third chapter, is description of detection approaches and algorithms that evaluate the similarity of software artifacts. The fourth chapter describes the algorithm of adaptive local alignment of the keywords. I propose, based on the theoretical analysis, a detection process that uses adaptive local alignment. Design and implementation of the application which evaluates the similarity of the programs on different levels, such as source code, bytecode, configuration and decompiled source codes, is described in the fifth and sixth section. Evaluation of the plagiarism detection, on several levels within applications, is evaluated in the seventh section. The final chapter summarizes achieved goals, defined in the beginning.
