Abstract: This paper proposes an automatic analysis and operating functions of CSCL utterance logs. First, the authors specified a data scheme called COLCOX and relevant XML bindings in order to represent CSCL utterance with structure and meanings. Next, an automatic analysis method was proposed to resolve elliptical phenomena in CSCL discussions with use of case analysis for spoken words. Further, an automatic exchange function was developed between LMS. An open source LMS of Moodle was utilised and expanded to install these functions. With use of the proposing functions, a learner group is able to search related utterances of various standpoints.

Keywords: collaborative learning; CSCL utterances; NLP; ellipsis resolution; web services; XML bindings; spoken words.
