We present a method that paraphrases a given sentence by first generating candidate paraphrases and then ranking (or classifying) them. The candidates are generated by applying existing paraphrasing rules extracted from parallel corpora. The ranking component considers not only the overall quality of the rules that produced each candidate, but also the extent to which they preserve grammaticali...

The potential of sentence generators as engines in Intelligent Computer-Assisted Language Learning and teaching (ICALL) software has hardly been explored. We sketch the prototype of COMPASS, a system that supports integrated writing and grammar curricula for 10 to 14 year old elementary or secondary schoolers. The system enables firstor second-language teachers to design controlled writing exer...

This article introduces Discourse Combinatory Categorial Grammar (DCCG) and shows how it can be used to generate multisentence paraphrases, flexibly incorporating both intraand intersentential discourse connectives. DCCG employs a simple, practical approach to extending Combinatory Categorial Grammar (CCG) to encompass coverage of discourse-level phenomena, which furthermore makes it possible t...

Detecting paraphrase is an important and challenging task. It can be used in paraphrases generation and extraction, machine translation, question and answer and plagiarism detection. Since the same meaning of a sentence is expressed in another sentence using different words, it makes the traditional methods based on lexical similarity ineffective. In this paper, we describe a strategy of Detect...

For resource-limited language pairs, coverage of the test set by the parallel corpus is an important factor that affects translation quality in two respects: 1) out of vocabulary words; 2) the same information in an input sentence can be expressed in different ways, while current phrase-based SMT systems cannot automatically select an alternative way to transfer the same information. Therefore,...

Many terminal devices for mobile environment such as mobile phones have small and low resolution screens compared to the big and high resolution screen of personal computers. In this circumstance, Web pages for ordinary personal computer and mobile phones written in the same language are developed separately even though they describe the same topic or contents. In this research, we collected We...

The soundness of syntax is an important issue for the paraphrase generation task. Most methods control paraphrases by embedding and semantics in process, which cannot guarantee syntactical correctness results. Different from them, this paper we investigate structural patterns word usages termed as composable knowledge integrate it into to explicit way. This pretrained on a large corpus with dep...

Hybrid System Combination for Machine Translation: An Integration of Phrase-level and Sentence-level Combination Approaches Wei-Yun Ma Given the wide range of successful statistical MT approaches that have emerged recently, it would be beneficial to take advantage of their individual strengths and avoid their individual weaknesses. Multi-Engine Machine Translation (MEMT) attempts to do so by ei...

The queries to a practical Question Answering (QA) system range from keywords, phrases, badly written questions, and occasionally grammatically perfect questions. Among different kinds of question analysis approaches, the pattern matching works well in analyzing such queries. It is costly to build this pattern matching module because tremendous manual labor is needed to expand its coverage to s...
