Multilingual modeling of cross-lingual spelling variants

Technical term translations are important for cross-lingual information retrieval. In many languages, new technical terms have a common origin rendered with different spelling of the underlying sounds, also known as cross-lingual spelling variants (CLSV). To find the best CLSV in a text database index, we contribute a formulation of the problem in a probabilistic framework, and implement this with an instance of the general edit distance using weighted finite-state transducers. Some training data is required when estimating the costs for the general edit distance. We demonstrate that after some basic training our new multilingual model is robust and requires little or no adaptation for covering additional languages, as the model takes advantage of language independent transliteration patterns. We train the model with medical terms in seven languages and test it with terms from varied domains in six languages. Two test languages are not in the training data. Against a large text database index, we achieve 64–78 % precision at the point of 100% recall. This is a relative improvement of 22% on the simple edit distance.

字本位理论和汉语语法的研究策略

“字本位理论”的主要观点为“字”是汉语语法结构中的基础单位。汉字具有非线性单位性质，它以汉语音义结合的理据性为基点，在汉语语法结构中处于核心地住。以字为本位，有助于消除古今汉语研究的断层，建立起古今汉语研究的共同轴心，形成方法论的基础，并使之推理成汉语语法一种独特的研究策略。

Non-linear 2-DOF model and centre manifold theory to study limit cycle oscillations caused by drum-brake judder

This paper presents the research on the laws of systematic-parameter dependent variation in the vibration amplitude of drum-brake limit cycle oscillations (LCO). We established a two-degree non-linear dynamic model to describe the low-frequency vibration of the drum brake, applied the centre manifold theory to simplify the system, and obtained the LCO amplitude by calculating the normal form of the simplified system at the Hopf bifurcation point. It is indicated that when the friction coefficient is smaller than the friction coefficient at the bifurcation point, the amplitude decreases; whereas with a friction coefficient larger than the friction coefficient of bifurcation point, LCO occurs. The results suggest that it is applicable to suppress the LCO amplitude by changing systematic parameters, and thus improve the safety and ride comfort when applying brake. These findings can be applied to guiding the design of drum brakes.

从顺应论看林语堂编译《论语》

根据维索尔伦提出的顺应观,译者的翻译行为是一系列动态的选择过程,译者的任务是顺应目标语读者的时间、语境和语言的结构特征,从而让其译作被目的语读者所接受,以达到文化交流的目的。林语堂有选择地编译了中国经典作品《论语》,其翻译行为顺应了当时目的语读者的时代背景、文化语境及语言特征,成功地实现了翻译目的。
