This section provides an overview on related works that deal with Arabic plagiarism detection especially in paraphrase identification field based on semantic analysis to determine the relatedness between the suspect and source Arabic text documents.
several similarity detection approaches between documents have been proposed in the literature of which there are three types of methods for computing relatedness according to the type of resources that have been used, we distinguish: • Knowledge-based methods relies on some form of ontology using WordNet which is a well-known knowledge source to compute semantic similarity between words as in (Shenoy et al, 2012) that proposed a semantic plagiarism detection system using ontology mapping where ontologies are a computational model of some domain of the world by describing semantics of terms used in the domain.
