- Abstract:
-
To effectively provide personalized Elearning in a community, an adaptive filt ering algorithm for identifying appropriate teaching resources was developed. It is based on a vector space model, an improvement on traditional algorithms used for this purpose. Firstly, feature selection and pseudo feedback were used to e st ablish the initial templates and thresholds through a training algorithm. Then t he user’s feedback was utilized to modify the templates and thresholds adaptivel y for the filtering algorithm. The algorithm did not need massive quantities of initial texts to begin the process of filtering. Furthermore, filtering precisio n improved during the process through self learning. The algorithm proved effect ive as a personalized knowledge service system for community Elearning.
