Our proposed method is based on the automatically acquired paraphrase dictionary described in Callison-Burch ( 2008 ) , in which the application of paraphrases from the dictionary encodes secret bits .
syntactic constraints on paraphrases extracted from parallel corpora

linguistic in nature , rather than dealing with superficial properties of the text , e.g. the amount of white space between words ( Por et al. , 2008 ) . Our proposed method is based on the automatically acquired paraphrase dictionary described in Callison-Burch ( 2008 ) , in which the application of paraphrases from the dictionary encodes secret bits . One advantage of the dictionary is that it has wide coverage , being automatically extracted ; however , a disadvantage is that it contains many paraphrases which are either inappropriate , or only appropriate in certain contexts .
