A Survey on Paraphrase Detection Techniques for Indian Regional Languages

Whenever the text contains multiple ways of saying “the same thing,” but the application requires the same treatment of those various alternatives, an automated paraphrase recognition mechanism would be useful. One reason why paraphrase recognition systems have been difficult to build is because paraphrases are hard to define. Although the strict interpretation of the term “paraphrase” is quite narrow because it requires exactly identical meaning, in linguistics literature paraphrases are most often characterized by an approximate equivalence of meaning across sentences or phrases. This paper presents a survey of paraphrase detection techniques for Indian regional languages.
