Focused web crawling in the acquisition of comparable corpora

Cross-Language Information Retrieval (CLIR) resources, such as dictionaries and parallel corpora, are scarce for special domains. Obtaining comparable corpora automatically for such domains could be an answer to this problem. The Web, with its vast volumes of data, offers a natural source for this. We experimented with focused crawling as a means to acquire comparable corpora in the genomics domain. The acquired corpora were used to statistically translate domain-specific words. The same words were also translated using a high-quality, but non-genomics-related parallel corpus, which fared considerably worse. We also evaluated our system with standard information retrieval (IR) experiments, combining statistical translation using the Web corpora with dictionary-based translation. The results showed improvement over pure dictionary-based translation. Therefore, mining the Web for comparable corpora seems promising.     

英语书面语中模糊限制语的使用差异研究

基于BROWN,LOB,CLEC三个书面语语料库,通过对比英语本族语者与中国英语学习者英语书面语中模糊限制语的使用情况,探讨影响中国英语学习者英语写作中模糊限制语使用的因素,指出学生在英语写作中应尽可能避免文化思维差异及母语迁移对写作的影响,而教师在教学中应尽量加强对模糊限制语的研究,使学生在表达中增强正确使用模糊限制语的意识,达到成功交流的目的。     

基于语料库的搭配力研究——以place一词为例

词语搭配是语料库语言学的研究热点,该类研究对语言学习、词典编撰和语言教学有重要启示作用。本文介绍了搭配力的三种计算方法,然后以place一词为例,通过BNC的检索,探寻该节点词的显著搭配词,并计算其搭配力。     

基于语料库的精读教学与写作

语料库正被广泛运用到外语教学,在精读教学中借助语料库进行写作教学不仅有利于丰富精读课程,提高学生的学习兴趣,还有利于培养学生独立学习的能力,促进写作能力的提高。     

Effects of jinlu, an anti-juvenile hormone on the growth, ultra-structure of the corpora allata and prothoracic gland of silkworm,Bombyx mori L

The 4th instar larvae of the silkworm,Bombyx mori L, when treated with anti-juvenile hormone (Jinlu) had its larval period extended by 2 days and the total larval period shortened by about 4 days. The conversion ratio of tetramolters into trimolters was 100%. But anti-juvenile hormone administration to the 5th instar larvae lengthened the silkworm age by one day. When anti-juvenile hormone was administered, we could find many neurosecretory granules of the brain transferred to the cells of the corpora allata, but there was little endoplasmic reticulum. In the prothoracic gland, the micropile edge was clear and there were large nucleoli, mitochondria and endoplasmic reticulum. This study was carried out to show that anti-JH compound inhibits the secretion of Juvenile hormone in silkwormBombyx mori L. The investigation revealed that the antijuvenile hormone inhibited the secretion of corpora allata and initiated the activity of the prothoracic gland.

对竞技体育中"以赛带练"的质疑

运用文献资料法、逻辑推理法,根据心理学、社会学、训练学对逐渐渗透到训练中的“以赛带练”思想进行论证。依据“训练”和“比赛”的概念和目的得知,“练”是一种训练过程;而“赛”是一种目的性过程。竞技运动员多少年如一日,不断拼搏,是与其持续实践又不断提高的成就动机的推动分不开的。因而对“以赛带练”这种提法是不完全符合逻辑理论根据的。

基于语料库的英汉习语隐喻认知对比研究——以“红”和“蓝”习语为例

隐喻不仅是一种语言现象,还是一种思维方式和认知工具,是思维与语言的纽带。本文基于语料库,对英汉"红"和"蓝"习语中的隐喻认知加以分析,证实由于历史文化背景造成的认知心理上的差异,使英汉这两种颜色词带有各自的民族文化特点,其中体现的隐喻认知也必然表现出各自的差异。
