基于隐藏变量区别模型的中文多词表达抽取

Discriminative Latent Model (DLM) is proposed for Multiword Expressions (MWEs) extraction in Chinese text to improve the performance of Machine Translation (MT) system such as Template Based MT (TBMT). For MT systems to become of further practical use, they need to be enhanced with MWEs processing capability. As our study towards this goal, we propose DLM, which is developed for sequence labeling task including hidden structures, to extract MWEs for MT systems. DLM combines the advantages of existing discriminative models, which can learn hidden structures in sequence labeling task. In our evaluations, DLM achieves precisions ranging up to 90.73% for some type of MWEs, which is higher than state-of-the-art discriminative models. Such results demonstrate that it is feasible to automatically identify many Chinese MWEs using our DLM tool. With MWEs processing model, BLEU score of MT system has also been increased by up to 0.3 in close test.

Good applications for crummy machine translation

Ideally, we might hope to improve the performance of our MT systems by improving the system, but it might be even more important to improve performance by looking for a more appropriate application. A survey of the literature on evaluation of MT systems seems to suggest that the success of the evaluation often depends very strongly on the selection of an appropriate application. If the application is well-chosen, then it often becomes fairly clear how the system should be evaluated. Moreover, the evaluation is likely to make the system look good. Conversely, if the application is not clearly identified (or worse, if the application is poorly chosen), then it is often very difficult to find a satisfying evaluation paradigm. We begin our discussion with a brief review of some evaluation metrics that have been tried in the past and conclude that it is difficult to identify a satisfying evaluation paradigm that will make sense over all possible applications. It is probably wise to identify the application first, and then we will be in a much better position to address evaluation questions. The discussion will then turn to the main point, an essay on how to pick a good niche application for state-of-the-art (crummy) machine translation.

Current research in Machine Translation

This paper, accompanied by peer group commentary and author's response, is a discussion paper concerning the state of the art in Machine Translation. The current orthodoxy is first summarized, then criticized. A number of research projects based on the standard architecture are discussed: they involve the use of Artificial Intelligence techniques, advanced linguistic theories, and sublanguage. Alternative approaches discussed are systems which develop or update their grammars semi-automatically, dialogue MT, and corpus-based MT including example-based and statistical approaches.

FBG轴向非均匀应变分布的遗传规划重构方法

针对现有的光纤Bragg光栅轴向非均匀重构方法需预先对应变分布形式做假设而实际结构中应变分布是任意的这一问题,基于新兴的遗传规划(GP)算法,提出一种重构FBG轴向非均匀应变分布的方法,利用GP自动设计并优化应变分布的函数表达式,使应变重构的空间分辨率可以达到任意值。多种应变分布形式下的应变重构仿真结果表明,GP方法可以有效地进行光栅轴向非均匀应变分布的连续重构,精度和计算效率较现有方法有明显提高。
