The multilingual Paraphrase Database (PPDB) is a freely available automatically created resource of paraphrases in multiple languages. In statistical machine translation, paraphrases can be used to provide translation for out-of-vocabulary (OOV) phrases. In this paper, we show that a graph propagation approach that uses PPDB paraphrases can be used to improve overall translation quality. We pro...

The quality of a sentence translated by a machine translation (MT) system is difficult to evaluate. We propose a method for automatically evaluating the quality of each translation. In general, when translating a given sentence, one or more conditions should be satisfied to maintain a high translation quality. In EnglishJapanese translation, for example, prepositions and infinitives must be app...

During the last years there is increasing interest in methods that perform some kind of weighting of heterogeneous parallel training data when building a statistical machine translation system. It was for instance observed that training data that is close to the period of the test data is more valuable than older data (Hardt and Elming, 2010; Levenberg et al., 2010). In this paper we obtain suc...

In aiming at research and development on machine translation, we produced a test collection for Japanese-English machine translation in the seventh NTCIR Workshop. This paper describes details of our test collection. From patent documents published in Japan and the United States, we extracted patent families as a parallel corpus. A patent family is a set of patent documents for the same or rela...

To aid research and development in machine translation, we have produced a test collection for Japanese/English machine translation. To obtain a parallel corpus, we extracted patent documents for the same or related inventions published in Japan and the United States. Our test collection includes approximately 2 000 000 sentence pairs in Japanese and English, which were extracted automatically ...

game-based practicing of materials can be seen as a method of capturing an essence of real- life expe-rience which is commonly missing in the conventional face-to-face classrooms. to serve the l2 learn-ers' immediate communicative needs in wider classroom and societal contexts, this study sought to place l2 english learners within an interactional social framework through reinforcing their...
