A facet classification model is consisted by a set of facets which used to describe resources nature (facets term), thus to built each teaching resource description tree or query matches tree. Users through the provision of key words (terms) to form query conditions, and constitutes a facet query tree, through the appropriate matching algorithm to compare describe tree and matching tree, according to the size of the values i returned, and find out the approximate matching set of teaching resources and orderly presented to the user.
