Design And Implementation About Key Modules Of An English Teaching System Based On J2EE

With the development of Internet technology, Web-based English teaching system came into being and quickly developed. Although online-learning systems have different forms, they have the same basic functions--sharing information and exchanging ideas between teachers and students. However, there are some common problems among these. First, these systems are less related to the real class; second, the guidance provided by the learning materials is not strong. Modules discussed in this article belong to a complete English language teaching system, which solves the two problems mentioned earlier.Not only provide simulated classroom environment in the network, which offer a good combination of them,but also enhance the guidance through the rational design of reading,writing and translation module in two sides.First,offering the management platform of English study documents,second,offering the analysis function of sections and chapters by marking the dates rationally.This article firstly makes a detailed research on the development status of English teaching system at home and abroad and systematically discusses identification of English basic noun phrase technology, sentence similarity measurement algorithm and the engine technology of Java rules,and introduce the key technique of the system relyed on, then it puts forward a measure based on corpus to solve the problem of identification of English basic noun phrase.Secondly, according to the characters of English teaching, it systematically introduces the design and implementation about phrase and sentence modules and the excellent performance of these two modules, which are providing a management tool for teachers and a good assistant to help students study by themselves.
