项目摘要

The goal of the proposed project is to enable the use statistical machine translation (SMT) for the difficult task of translation of university lectures. This is done by enhancing SMT by a mutually beneficial learning cycle, called auto-adaptive SMT, that incorporates the human for post-editing SMT output from which the system can learn immediately. In the ``traditional'' setup, post-editors are instructed to produce a perfect translation, which can be very resource-intensive, not only in terms of editing time but also in terms of a user's required language proficiency. In this project, it is our main goal to explore ways of learning from weaker feedback than a full post-edit. This feedback could consist of partial corrections or merely judgments on the quality of the SMT output. A central point is that in order to guarantee machine learnability, human feedback needs to contain a signal strong enough for statistical learning. This means that we are faced with a trade-off between machine learnability and elicitability of feedback from human users, which we will attempt to solve. Our research will focus on the design of efficient algorithms that perform learning from weak feedback, and on frontend/backend interfaces that support a practical use of the algorithms in field tests of interactive translation of university lectures.

该项目的目标是使用统计机器翻译（SMT）来完成大学讲座翻译的艰巨任务。这是通过一个互利的学习周期来增强SMT来实现的，称为自适应SMT，它包含了人类对SMT输出的后期编辑，系统可以立即从中学习。在“传统”设置中，要求后期编辑提供完美的翻译，这可能是非常资源密集型的，不仅在编辑时间方面，而且在用户所需的语言熟练程度方面。在这个项目中，我们的主要目标是探索从弱反馈中学习的方法，而不是完整的后期编辑。这种反馈可以包括部分校正或仅仅是对SMT输出质量的判断。一个中心点是，为了保证机器的可学习性，人类的反馈需要包含一个足够强的信号来进行统计学习。这意味着我们面临着机器学习能力和人类用户反馈的可启发性之间的权衡，我们将尝试解决这个问题。我们的研究将集中在设计有效的算法，执行学习弱反馈，并在前端/后端接口，支持实际使用的算法在现场测试的交互式翻译的大学讲座。
