| Abstract(in English) | The machine-translated text is playing an important role in modern life which establishes wide communication among various communities using different languages. However, attackers are exploiting it to create a lot of untrusted information. Therefore, how to detect such information becomes a great demand in preventing the over-belief in this artificial content. Previous methods have measured the coherence of words among sentences of a paragraph. However, they ignore relationships of words in an individual sentence. We have thus developed a method by matching similar words within a paragraph for estimating the paragraph-level coherence, which is used to identify machine-translated text. The experiments on 4000 English human-generated and 4000 English machine-translated paragraphs show that our coherence-based method achieves high accuracy 87.0% and 98.2% which outperforms the previous methods best accuracy 72.4% and 96.6% in German and Japanese, respectively. |
