Identifying Japanese-Chinese Bilingual Synonymous Technical Terms from Patent Families

چکیده
In the task of acquiring Japanese-Chinese technical term translation equivalent pairs from parallel patent documents, this paper considers situations where a technical term is observed in many parallel patent sentences and is translated into many translation equivalents and studies the issue of identifying synonymous translation equivalent pairs. First, we collect candidates of synonymous translation equivalent pairs from parallel patent sentences. Then, we apply the Support Vector Machines (SVMs) to the task of identifying bilingual synonymous technical terms, and achieve the performance of over 85% precision and over 60% F-measure. We further examine two types of segmentation of Chinese sentences, i.e., by characters and by morphemes, and integrate those two types of segmentation in the form of the intersection of SVM judgments, which achieved over 90% precision.

Collecting Bilingual Technical Terms from Patent Families of Character-Segmented Chinese Sentences and Morpheme-Segmented Japanese Sentences
In manual translation of patent documents, a technical term bilingual lexicon is inevitable for a translator to efficiently translate patent documents. Dong et al. (2015) proposed a method of generating bilingual technical term lexicon from morpheme-segmented parallel patent sentences. The proposed method estimates Japanese-Chinese translation of technical terms using the phrase translation tab...
متن کاملEvaluating Features for Identifying Japanese-Chinese Bilingual Synonymous Technical Terms from Patent Families
In the process of translating patent documents, a bilingual lexicon of technical terms is inevitable knowledge source. It is important to develop techniques of acquiring technical term translation equivalent pairs automatically from parallel patent documents. We take an approach of utilizing the phrase table of a state-of-theart phrase-based statistical machine translation model. First, we coll...
متن کاملExtraction of Bilingual Technical Terms for Chinese-Japanese Patent Translation
The translation of patents or scientific papers is a key issue that should be helped by the use of statistical machine translation (SMT). In this paper, we propose a method to improve Chinese–Japanese patent SMT by premarking the training corpus with aligned bilingual multi-word terms. We automatically extract multi-word terms from monolingual corpora by combining statistical and linguistic fil...
متن کاملBilingual Multi-Word Term Tokenization for Chinese–Japanese Patent Translation
We propose to re-tokenize data with aligned bilingual multi-word terms to improve statistical machine translation (SMT) in technical domains. For that, we independently extract multi-word terms from the monolingual parts of the training data. Promising bilingual multi-word terms are then identified using the sampling-based alignment method by setting some threshold on translation probabilities....
