background: echinococcus granulosus , a zoonotic cestode parasite, causative agent of hydatid cyst is endemic in many parts of the world including the middle east. study on different aspects of this parasite is very important and valuable. however, working with adult worms which their habitat situated in the small intestine of canids, is dangerous and risky. achieving such risky situa­tion need...

in the past, residents of arabic island were divided into ghahtanis or hemieris in south and adnanis in north. these two were great nations that left several texts from their own language that there is no doubt about the authenticity of them. by scientific analysis of these texts, historical and literary results can be drawn. the ancient linguists believed that ghahtani's language is diffe...

This paper presents a method for generating multiple paraphrases from ambiguous logical forms. The method is based on a chart structure with edges indexed on semantic information and annotations that relate edges to the semantic facts they express. These annotations consist of logical expressions that identify particular realizations encoded in the chart. The method allows simultaneous generati...

We describe a method for recognizing textual entailment that uses the length of the longest common subsequence (LCS) between two texts as its decision criterion. Rather than requiring strict word matching in the common subsequences, we perform a flexible match using automatically generated paraphrases. We find that the use of paraphrases over strict word matches represents an average F-measure ...

One particular information can be conveyed by many different sentences. This variety concerns the choice of vocabulary and style as well as the level of detail (from laconism or succinctness to total verbosity). Although verbosity in written texts is considered bad style, generated verbosity can help natural language processing (NLP) systems to fill in the implicit knowledge. The paper presents...

Paraphrase recognition is the task of identifying whether two pieces of natural language represent similar meanings. This paper describes a system participating in the shared task 1 of SemEval 2015, which is about paraphrase detection and semantic similarity in twitter. Our approach is to exploit semantically meaningful features to detect paraphrases. An existing state-of-the-art model for pred...

Monolingual text-to-text generation is an emerging research area in Natural Language Processing. One reason for the interest in such generation systems is the possibility to automatically learn text-to-text generation strategies from aligned monolingual corpora. In this context, paraphrase detection can be seen as the task of aligning sentences that convey the same information but yet are writt...

1. P A R A P t l R A S E S IN I ) I A L O G U E S If you look at ordinary dialogues you will find that communication failures i.e. different types of misunderstandings happen frequently, cf [Ringle & Bruce 1982]. One important techaique for the participants of the communication to solve these problems is paraphrasing, that is, saying it again in other words. Parapla-ases can be offered by the h...

We present a simple, prepackaged solution to generating paraphrases of English sentences. We use the Paraphrase Database (PPDB) for monolingual sentence rewriting and provide machine translation language packs: prepackaged, tuned models that can be downloaded and used to generate paraphrases on a standard Unix environment. The language packs can be treated as a black box or customized to specif...
