提出一种基于认知复杂度度量的文本推荐模型.已有的认知复杂度评价方法主要用于评价单一文本的认知复杂度,对此方法进行拓展,将它用于文本集的认知复杂度评价.在推荐模型中,通过对用户查看文章序列的分析,然后使用文本集认知复杂度评价方法查找文章进行推荐,使得用户获得的推荐文本集合更符合认知的规律,更易于理解.实验结果表明文本集认知复杂度评价方法的合理性,并通过比较说明了使用这种推荐模型将使用户获得更加易于理解的文本推荐集合.%A document recommendation model based on cognitive difficulty measurement is presented. The existing cognitive difficulty measurement algorithm is designed to work on single document. The algorithm is improved to measure the cognitive difficulty of document set. In the recommendation model of this paper, according to the documents which the user has read, a recommended document set is given through cognitive difficulty measurement. The given documents witl help the reader to understand the document more easily. At the end, the reasonability of cognitive difficulty measurement algorithm of document set is proved by experiment. Through comparison, the recommendation model is proved to be more easily to cognitive for the readers.
