... produced 9483 pairs of lexical paraphrases and 25 morpho-syntactic rules. To evaluate the quality of produced paraphrases, we picked at random 500 paraphrasing pairs from the lexical paraphrases produced ... In addition to learning lex- ical paraphrases, the method also learns syntactic paraphrases, by generalizing syntactic patterns of the extracted paraphrases. Extracted paraphrases...
