A Cooperative Authoring System for Teaching Chinese as a Foreign Language

Shortage of a collaborative and automated platform has put textbook authoring for teaching Chinese as a foreign language into trouble. Furthermore, for lots of published textbooks, there are lots of defects which make them unacceptable. In this paper, a novel system based on computer supported cooperative work (CSCW) was developed to solve these problems. In order to improve the speed and accuracy of automatic phonetic notation, a method that combines string matching with statistics based on hidden Markov model was proposed, and a method of cross-text search and computing is adopted to control the amount and recurrence rate of new words. To get suitable examples for words, an algorithm for corpus indexing and retrieval is presented. Result indicates that textbooks authored on this system are scientific
