By demand of expression, a double negation sentences are used in many situations. According to characteristics of double negation sentences, a paraphrase method based on templates is used. The method analysis sentence structure of double negation sentences, extract syntax frame and construct paraphrase templates. The syntax structure of double negative sentence and affirmation sentence are suit...

We present a novel method for extracting parallel sub-sentential fragments from comparable, non-parallel bilingual corpora. By analyzing potentially similar sentence pairs using a signal processinginspired approach, we detect which segments of the source sentence are translated into segments in the target sentence, and which are not. This method enables us to extract useful machine translation ...

the study of the sentence and its divisions has been always a cause of difference in syntactical viewpoints among the ancient and modern arab grammarians. ibn hesham sees three divisions for the arabic sentence: the noun sentence, the verb sentence and the adverb sentence. the adverb sentence in his view is that in which a time or place adverb or a prepositional phrase is the predicate proceede...

The syntax structure of double negative sentence and affirmation sentence are suitable for paraphrase. By syntax analyzing structure of double negative sentences and their affirmation sentence, proposed method abstract paraphrase templates. Matching of paraphrase template with paraphrase sentences is completed by calculating their similarity. The small-scale experiments have been done and got t...

Abstract We present a new method for learning to parse a bilingual sentence using Inversion Transduction Grammar trained on a parallel corpus and a monolingual treebank. The method produces a parse tree for a bilingual sentence, showing the shared syntactic structures of individual sentence and the differences of word order within a syntactic structure. The method involves estimating lexical tr...

A dependency parsing method based on sentence segmentation into clauses has been proposed and confirmed to be effective. In this method, dependency parsing is executed in two stages: at the clause level and the sentence level. However, since a sentence can not be segmented into complete clauses, in the past research, a unit sandwiched between two clause-end boundaries (clause boundary unit) was...

Methods for text simplification using the framework of statistical machine translation have been extensively studied in recent years. However, building the monolingual parallel corpus necessary for training the model requires costly human annotation. Monolingual parallel corpora for text simplification have therefore been built only for a limited number of languages, such as English and Portugu...

Extracting biomedical relations such as drug-drug interaction (DDI) from text is an important task in biomedical NLP. Due to the large number of complex sentences in biomedical literature, researchers have employed some sentence simplification techniques to improve the performance of the relation extraction methods. However, due to difficulty of the task, there is no noteworthy improvement in t...
