Abstract
The paper analyzes the shortcomings of the information gain method, applies frequency, concentration and dispersion to the information gain method, and proposes a feature optimization selection method based on information gain. By introducing the service resource framework WSRF technical specification, a new grid distance education system model GEM based on the open grid service structure OGSA. According to the existing problems of modern distance education, a distributed distance education system based on object Web computing is studied by using CORBA/Java. On this basis, a new dynamic distributed system structure technology and idea based on object-oriented technology is applied to develop and realize the distance education question bank system.
