摘要 提出了用领域词典代表给定协作主题特征,并且用机械分词与串频统计相结合的方法实现了一个计算机支持的协作学习中相关度监控的领域词典构建系统.从而可以通过对学习者协作内容文本与领域词典中代表协作主题的特征词的相似度计算,判断学习者协作活动与协作主题的相关度. This paper put forwards a domain dictionary to represent the character of cooperative subject so that the law of cosines can be used to calculate the similitude of two vectors to accomplish the pertinency monitoring.
