| Abstract: | On the basis of extension information net of a field knowledge and CELTS-3,this paper targeted at text-typed teaching resources,and elaborated the process of design and implementation for teaching resources organizing system based on information units,including a describing basic data frame of information characteristic,obtainment of characteristic words, distance between information units,as well as matching rules and algorithm of information unit,etc.The system organizes infi- nite teaching resources by finite information units,implements efficient organization of the teaching resources,and thus sup- ports the resources automatic regrouping in the process of learning. |

| Keywords: | teaching resource information unit characteristic word describing basic data frame matching rule matching algorithm |
