Plagiarism Detection: An Overview of Text Alignment Techniques
MetadataShow full item record
The task of plagiarism detection is to look at a given document and establish whether it is an original or not. More specifically, it concerns the disclosure of which sentences or passages are plagiarised from which respective passages. The strategies of uncovering plagiarism rely on the kind of natural language representation chosen. Plagiarism detection asks for two major tasks. Retrieving a possible source document, and then performing the detailed analysis that would produce the exact detection result. This thesis is mainly concerned with the detailed analysis phase, more specifically with the problem of text alignment and the other subtasks that follow from it.
