中西方价值观差异的形成及其在语言中的体现

中西方自然环境、历史条件和思维方式的哲学基础的差异使中西方社会群落形成了不同的价值观念，这种差异在语言中得到了充分的体现。对价值观差异的形成及其在语言中的体现的研究可以为汉英对比研究提供一条新的思路，也可以帮助英语学习者增强文化的差异意识，提高跨文化交际能力。     

New Retrieval Method Based on Relative Entropy for Language Modeling with Different Smoothing Methods

A language model for information retrieval is built by using a query language model to generate queries and a document language model to generate documents. The documents are ranked according to the relative entropies of estimated document language models with respect to the estimated query language model. Two popular and relatively efficient smoothing methods, the Jelinek- Mercer method and the absolute discounting method, are used to smooth the document language model in estimation of the document language, A combined model composed of the feedback document language model and the collection language model is used to estimate the query model. A performacne comparison between the new retrieval method and the existing method with feedback is made, and the retrieval performances of the proposed method with the two different smoothing techniques are evaluated on three Text Retrieval Conference （TREC） data sets. Experimental results show that the method is effective and performs better than the basic language modeling approach; moreover, the method using the Jelinek-Mercer technique performs better than that using the absolute discounting technique, and the perfomance is sensitive to the smoothing peramters.

A Semi-automatic Method Based on Statistic for Mandarin Semantic Structures Extraction in Specific Domains

This paper proposed a new method of semi-automatic extraction for semantic structures from unlabelled corpora in specific domains. The approach is statistical in nature. The extracted structures can be used for shallow parsing and semantic labeling. By iteratively extracting new words and clustering words, we get an inital semantic lexicon that groups words of the same semantic meaning together as a class. After that, a bootstrapping algorithm is adopted to extract semantic structures. Then the semantic structures are used to extract new key words and augment the semantic lexicon. The resultant semantic structures are interpreted by persons and are amenable to handediting for refinement. In this experiment, the semi-automatically extracted structures SSA provide recall rate of 84.5%.

C语言教学探讨

C语言是近年来在国内外得到迅速推广应用的一种计算机语言。在教学实践中发现,C语言内容抽象、很难学,尽是些复杂的算法,如何才能提高C语言课程的教学效果,如何在有限的课堂教学里,激发学生学习C语言的兴趣,提高学生运用C语言的实际能力,使学生在短暂的课堂学习时间内学到尽可能多的C语言概念和C语言编程技巧,便成了每位教授该门课程的计算机教师应该研究的重要课题。针对以上问题,介绍了"大作业与小作业"相结合,培养编程能力,典型算法,多媒体,理论与实践并重等教学方法。     

论张爱玲小说语言的审美特征

张爱玲的作品在语言风格方面很有特色,对人物及环境准确的描摹、精当的造语、机智幽默的警句、顾盼生姿的行文,使其小说语言非常讲究,精练、雅致而易懂,有着绚烂寓于平淡之中的艺术美感。     

语言的灵活性与逻辑的严密性

语言作为人类社会交际的工具,具有灵活性的特点。而逻辑作为一门古老的学科,则具有严密性的特点。语言的灵活性与逻辑的严密性关系如何?笔者通过对语言使用过程中所出现的人工语言以及在修辞手法过程中出现的语言现象进行详细分析,阐述了语言的灵活性与逻辑的严密性对立统一于人类语言使用过程中。
