Applying Structural Matching and Paraphrasing
نویسندگان
چکیده
We discuss the potentialities of structural matching as a compromise between fully-conceptual deep processing approaches and shallow bag-of-words approaches to answer seeking. We extended Collins's Tree Kernel [1] to formulate a new algorithm for soft structural matching, and we also developed and tested a method for combing structural matching with paraphrasing. Unfortunately, we found no positive empirical evidence that either structural matching or paraphrasing contribute to question answering. We believe , however, that their usefulness should not be ruled out yet. We still need more deliberate experiments and analysis.

NAIST QA System for QAC2
The system we presented for the subtask1 and subtask2 in QAC2 is based on our previous one [12], which utilized a greedy answer seeking model using paraphrasing. We incorporate a re-ranking model for matching questions and passages into the previous system. In the model, we integrated a proximitybased scoring function with the structural-based scoring function. Unfortunately, the result of eval...
متن کاملCan Translation Memories afford not to use paraphrasing?
This paper investigates to what extent the use of paraphrasing in translation memory (TM) matching and retrieval is useful for human translators. Current translation memories lack semantic knowledge like paraphrasing in matching and retrieval. Due to this, paraphrased segments are often not retrieved. Lack of semantic knowledge also results in inappropriate ranking of the retrieved segments. Gu...
متن کاملIncorporating Paraphrasing in Translation Memory Matching and Retrieval
Current Translation Memory (TM) systems work at the surface level and lack semantic knowledge while matching. This paper presents an approach to incorporating semantic knowledge in the form of paraphrasing in matching and retrieval. Most of the TMs use Levenshtein editdistance or some variation of it. Generating additional segments based on the paraphrases available in a segment results in expo...

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...
متن کاملComparing and Extracting Paraphrasing Words with 2-Way Bilingual Dictionaries
We analyze a variety of lexical expressions with 2-way bilingual dictionaries and propose a method for extracting paraphrasing words. First, we compare the coverage between an English-Japanese dictionary and a Japanese-English dictionary from the viewpoint of the returnability of the words by translating English to Japanese, and then back to English again. The variety is shown using examples. N...
