Outline of Final Research Achievements |
We built a statistical skill estimation method. We particularly focused on English-Japanese translation jobs and proposed a method which incorporates translators’ vocabulary knowledge for translation ability assessment. Our method involves just asking translators to tell if they know given words. Using this vocabulary information, we build a probabilistic model to estimate the translators’ vocabulary and translation abilities simultaneously. We evaluated our method in a realistic crowdsourcing translation set- ting in which there is a great need to measure translators’ translation ability to select good translators. The results of our experiments show that the proposed method accurately estimates translation ability and selects translators who have sufficient skills in translating a given sentence.
