This is done in order to allow the learners to gain more insight into the language structure and use, on the basis of which they can come to generalisations and formulate rules of grammar. Corpus-based language teaching and learning equips learners with knowledge and skills that can be used for this purpose. The advantage of using language corpora as teaching and learning materials is that they provide examples of authentic language. The chosen or built corpus is usually large enough to enable the learner to find a sufficient number of examples of a word or phrase in a context which is presented in an electronic form. As language corpora offer some obvious didactic advantages, they are becoming more and more popular among foreign language teachers and learners. The corpus is usually subjected to a concordance analysis which means using analytical software （a concordancer） to find the occurrences of a particular word or phrase in a text or in a compilation of texts. The aim of this paper is to present the possibilities which the use of a language corpus in combination with concordancing software give to teachers in their designing of language learning tasks After some brief theoretical foundations about the usefulness of concordancing, the paper presents the author＇s experience in the application of these tools in the classroom展开更多

However,getting a parallel corpus,which has a large scale and is of high quality,is a very difficult task especially for low resource languages such as Chinese-Vietnamese. Fortunately,multilingual user generated contents（ UGC）,such as bilingual movie subtitles,provide us access to automatic construction of the parallel corpus. Although the amount of UGC parallel corpora can be considerable,the original corpus is not suitable for statistical machine translation（ SMT） systems. The corpus may contain translation errors,sentence mismatching,free translations,etc. To improve the quality of the bilingual corpus for SMT systems,three filtering methods are proposed： sentence length difference,the semantic of sentence pairs,and machine learning. Experiments are conducted on the Chinese to Vietnamese translation corpus.Experimental results demonstrate that all the three methods effectively improve the corpus quality,and the machine translation performance（ BLEU score） can be improved by 1. 32.展开更多
