Compared to the edited genres that have played a central role in NLP research, microblog texts use a more informal register with nonstandard lexical items, abbreviations, and free orthographic variation. When confronted with such input, conventional text analysis tools often perform poorly. Normalization — replacing orthographically or lexically idiosyncratic forms with more standard variants —...

Usefulness of paraphrases • Paraphrases are alternative ways of conveying the same information • Useful in NLP application such as: – Generation producing paraphrases allows for the creation of more varied and fluent text – Multidocument summarization identifying paraphrases allows information repeated across documents to be condensed – Question answering paraphrasing is important when going be...

Text paraphrasing algorithms play a fundamental role in several NLP applications such as automated question answering (QA), summarization and machine translation. We propose a novel paraphrasing approach based on an entity-relation (ER) analysis of text. The algorithm uses a combination of deep linguistic analysis (part of speech, dependency parse information) and background resources (NGram, P...

ABSTRACT This paper describes the FRDC machine translation system for the NTCIR-9 PatentMT. The FRDC system JIANZHEN is a hierarchical phrase-based (HPB) translation system. We participated in all the three subtasks, i.e., Chinese to English, Japanese to English and English to Japanese. In this paper, we introduce a novel paraphrasing mechanism to handle a certain kind of Chinese sentences whos...

Cross-language plagiarism detection attempts to identify and extract automatically plagiarism among documents in different languages. Plagiarized fragments can be translated verbatim copies or may alter their structure to hide the copying, which is known as paraphrasing and is more difficult to detect. In order to improve the paraphrasing detection, we use a knowledge graph-based approach to ob...

We describe a preliminary version of Mutaphrase, a system that generates paraphrases of semantically labeled input sentences using the semantics and syntax encoded in FrameNet, a freely available lexicosemantic database. The algorithm generates a large number of paraphrases with a wide range of syntactic and semantic distances from the input. For example, given the input “I like eating cheese”,...

We discuss paraphrasing controlled English texts, by defining two fragments of Attempto Controlled English (ACE): Core ACE and NP ACE. We show that these fragments have features that one would usually expect from paraphrases. We also describe a tool that paraphrases ACE sentences into these fragments.

In this paper, we describe an implementation of object-oriented knowledge sources and functions for knowledge-based machine translation, where the meanings of sentences are represented by conceptual "objects." While parsing and generation are viewed as mappings between syntactic and conceptual representations, such functions as paraphrasing, abstraction, and information filtering are implemente...

In Reply: The comments of Dr Wiwanitkit are well taken. In our article (1), our main concern was to emphasize the big difference between plagiarism of ideas and plagiarism of text, especially in scientific writing, where we believe text is just a transfer medium for ideas, which are the essence of scientific work (2-5). Paraphrasing of a scientific text is not always easy, if possible at all (6...
