Statistical Language Model for Chinese Text Proofreading

Statistical language modeling techniques are investigated so as to construct a language model for Chinese text proofreading. After the defects of n-gram model are analyzed, a novel statistical language model for Chinese text proofreading is proposed. This model takes full account of the information located before and after the target word wi, and the relationship between un-neighboring words wi and wi in linguistic environment(LE). First,the word association degree between wi and wj is defined by using the distance-weighted factor, wi is l words apart from wi in the LE, then Bayes formula is used to calculate the LE related degree of word wi, and lastly, the LE related degree is taken as criterion to predict the reasonability of word wl that appears in context. Comparing the proposed model with the traditional n-gram in a Chinese text automatic error detection system, the experiments results show that the error detection recall rate and precision rate of the system have been improved.     

机器翻译中异化现象的分析及映射运算

本文从词汇－语义角度分析了机器翻译中与汉英语言相关的一些异化现象，探讨了语义－句法映射运算集的有效性和合理性．同时，本文讨论了通过变异映射集、变异类型指示器和参数合一机制解决机器翻译中异化现象的方法．这些方法提高了译准率，使生成的句子既能正确表达原中间语言的语义，又符合目标语言的表述习惯．

Evaluation of Linguistic Features for Word Sense Disambiguation with Self-Organized Document Maps

Word sense disambiguation automatically determines the appropriate senses of a word in context. We have previously shown that self-organized document maps have properties similar to a large-scale semantic structure that is useful for word sense disambiguation. This work evaluates the impact of different linguistic features on self-organized document maps for word sense disambiguation. The features evaluated are various qualitative features, e.g. part-of-speech and syntactic labels, and quantitative features, e.g. cut-off levels for word frequency. It is shown that linguistic features help make contextual information explicit. If the training corpus is large even contextually weak features, such as base forms, will act in concert to produce sense distinctions in a statistically significant way. However, the most important features are syntactic dependency relations and base forms annotated with part of speech or syntactic labels. We achieve 62.9% ± 0.73% correct results on the fine grained lexical task of the English SENSEVAL-2 data. On the 96.7% of the test cases which need no back-off to the most frequent sense we achieve 65.7% correct results.     

概念化心智活动的关键地位与交流的实现

语言符号并非天然地和它所指的客观事物或现象直接而精确地对应。人脑或心智活动的产物，即思想或概念，是将语言符号与客观事物或现象联系起来必不可少的媒介，这是Ogden和Richards名的语义三角理论的灵魂。由此可以认为，外界事物引起人脑主观思维活动并将其结果外化出来，这实质上是概念化问题。简要讨论了这种概念化过程的关键地位及其复杂性。     

文化差异及母语负迁移与英语教学

英语学习不仅仅是语言的学习，更是文化的学习．但长期以来，英语教学侧重的是对语言知识的传授．而对文化因素的教学一直是不自觉的；结果导致了学生文化敏感性较弱，易受母语文化的影响，给英语学习和跨文化交际带来了阻碍．因此，英语教学有必要加大对文化教学的力度。     

中国特色交际语言教学法的思考

生硬搬用某些教学法或武断地否认某些教学法都会给教学带来较大的损失．因此，外语教师应根据实际情况，灵活、适当地使用各种不同教学方法，博采众长，使教学取得更好的效果．针对广受学生欢迎的交际教学法中出现的问题，提出交际教学法应与传统教学法相结合，以达到良好的教学效果．     

The Effects of Auditory and Visual Linguistic Distractors on Target Localization.

In this experiment, a Stroop-like paradigm was used to investigate the ability to attend to visuospatial cues while ignoring distracting stimuli in the auditory or visual modality. In Part 1, the authors investigated whether linguistic cue words (i.e., RIGHT, LEFT, DOWN, and UP) would induce endogenous shifts of attention to visual targets. In Part 2, a relevant distractor stimulus was introduced in a different modality from the endogenous cues to investigate effects of interference. Twenty-five right-handed students served as participants. Auditory and visual linguistic cues were effective in inducing shifts of visual attention when cues were presented alone. Furthermore, introducing a distractor stimulus decreased the efficacy of these cues differently depending on modality, suggesting that language processing and visuospatial attention may share neuronal resources. Implications for unimodal and supramodal mechanisms of selective attention and relevant neuronal networks are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
