In this paper we review and list, the advantages and limitations of the significant
effective techniques employed or developed in text plagiarism detection. It was found that
many of the proposed methods for plagiarism detection have a weakness poi
nts and do not
detect some types of plagiarized operations.
This paper show a survey about plagiarism detection including several important
subjects in plagiarism detection, which is plagiarism definition, plagiarism prevention and
detection, plagiarism detection systems, plagiarism detection processes and some of the
current plagiarism detection techniques.
This paper compares between different plagiarism detection algorithms, and shows
the points of weakness, and points of efficiency, and describe the power of semantic
plagiarism detection methods, and shows its efficiency in detect plagiarism cases that
another plagiarism detection algorithms don’t able to detect these cases, that semantic
plagiarism detection methods are developed to get rid of traditional weakness points for all
plagiarism detection methods have.
