This paper presents a paraphrase acquisition method that uncovers and exploits generalities underlying paraphrases: paraphrase patterns are first induced and then used to collect novel instances. Unlike existing methods, ours uses both bilingual parallel and monolingual corpora. While the former are regarded as a source of high-quality seed paraphrases, the latter are searched for paraphrases t...
We describe a system which ranks humanprovided paraphrases of noun compounds, where the frequency with which a given paraphrase was provided by human volunteers is the gold standard for ranking. Our system assigns a score to a paraphrase of a given compound according to the number of times it has co-occurred with other paraphrases in the rest of the dataset. We use these co-occurrence statistic...
plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
Paraphrases are sentences or phrases that convey the same meaning using different wording. Although the logical definition of paraphrases requires strict semantic equivalence, linguistics accepts a broader, approximate, equivalence—thereby allowing far more examples of “quasiparaphrase.” But approximate equivalence is hard to define. Thus, the phenomenon of paraphrases, as understood in linguis...
Paraphrases play an important role in the variety and complexity of natural language documents. However they adds to the difficulty of natural language processing. Here we describe a procedure for obtaining paraphrases from news article. A set of paraphrases can be useful for various kinds of applications. Articles derived from different newspapers can contain paraphrases if they report the sam...
Jun Ma, Yujie Zhang, Jinan Xu, Yufeng Chen (Beijing Jiaotong University, Beijing, 100044, China ) Abstract: Conventional “pivot” approach of acquiring paraphrases from bilingual corpus has limitations, where only candidated paraphrases within two steps are considered. In this paper, we propose a graph based model of acquiring paraphrases from phrases translation table. First, we describe a grap...
Recognizing and generating paraphrases is an important component in many natural language processing applications. A wellestablished technique for automatically extracting paraphrases leverages bilingual corpora to find meaning-equivalent phrases in a single language by “pivoting” over a shared translation in another language. In this paper we revisit bilingual pivoting in the context of neural...
Researchers working on distributional semantics have recently taken up the challenge of going beyond lexical meaning and tackle the issue of compositionality. Several Compositional Distributional Semantics Models (CDSMs) have been developed and promising results have been obtained in evaluations carried out against data sets of small phrases and as well as data sets of sentences. However, we be...
Paraphrase and textual entailment generation can support natural language processing (NLP) tasks that simulate text understanding, e.g., text summarization, plagiarism detection, or question answering. A paraphrase, i.e., a sentence with the same meaning, conveys a certain piece of information with new words and new syntactic structures. Textual entailment, i.e., an inference that humans will j...
