摘要：本文以文本類型教學(xué)資源為研究對象，在領(lǐng)域知識可拓信息網(wǎng)模型和CELTS-3的基礎(chǔ)上，闡述了基于信息元的教學(xué)資源組織系統(tǒng)設(shè)計與實現(xiàn)過程，包括：信息特征元數(shù)據(jù)描述框架、特征詞獲取、信息元距離度量、信息元匹配規(guī)則以及匹配算法等。該系統(tǒng)通過有限的信息元描述無限的資源，實現(xiàn)了教學(xué)資源的高效組織，支持學(xué)習(xí)過程中資源自動重組。

Design and Implementation of Teaching Resources Organizing System Based on Information Units


【Abstract】 On the basis of extension information net of a field of knowledge and CELTS-3, this paper targets at text-typed teaching resources, and elaborates the process of design and implementation of teaching resources organizing system based on information units, including a frame describing basic data 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 infinite teaching resources by finite information units, implements efficient organization of the teaching resources, and thus supports the resources automatic regrouping in the process of learning.
【Key words】Teaching Resource; Information Unit; Characteristic Word; Frame Describing Basic Data; Matching Rule; Matching Algorithm
