Using Sentence Embedding for Cross-Language Plagiarism Detection

摘要

The growth of textual content in various languages and the advancement of automatic translation systems has led to an increase of cases of translated plagiarism. When a text is translated into another language, word order will change and words may be substituted by synonyms, and as a result detection will be more challenging. The purpose of this paper is to introduce a new technique for English-Arabic cross-language plagiarism detection. This method combines word embedding, term weighting techniques, and universal sentence encoder models, in order to improve detection of sentence similarity. The proposed model has been evaluated based on English-Arabic cross-lingual datasets, and experimental results show improved performance when compared with other Arabic-English cross-lingual evaluation methods presented at SemEval-2017.
