Multi-modal English Corpus Construction Based on Net Information

The application of multi-modality, a computer-assisted language teaching approach, takes multimedia materials such as audio and video as the main supporters, which promotes the multi-dimensional development of language acquisition in terms of pronunciation, semantics and pragmatics, thus having a great effect on influencing the reform of English teaching in universities at home and abroad. This paper focuses on the construction of multi-modal English corpus based on net information. On the basis of literature review, the relevant theory and research methods of multi-modal English corpus are referred to, and the major content of multi-modal corpus construction of net information is explored in detail. The constructed corpus is tested, and the test results show that the performance of the corpus-based method is 8.47% higher than that of the dictionary-based method, and the performance of a combination of the corpus-based method and the dictionary-based method is 11.56% higher than that of the dictionary-based method alone. By means of numerical analysis, the conclusion is drawn that bilingual corpora can be exploited to serve as an effective supplement to dictionaries.
