共享平台区别于其他平台的特征是市场中的个体用户可自行选择成为供给者或需求者。对用户行为和需求的研究有助于推动双边市场扩大规模,形成规模经济效应。情感倾向可以反映用户的态度和行为,而感知价值偏好是判断用户对共享平台关注重... 共享平台区别于其他平台的特征是市场中的个体用户可自行选择成为供给者或需求者。对用户行为和需求的研究有助于推动双边市场扩大规模,形成规模经济效应。情感倾向可以反映用户的态度和行为,而感知价值偏好是判断用户对共享平台关注重点的依据。在共享平台用户评论文本挖掘的基础上,检验用户的情感倾向和感知价值各维度的相关性,并根据各感知因素的权重分别计算出供给者市场和需求者市场不同情感倾向用户群体的感知价值偏好。结果发现:不同情感倾向用户群体的感知价值偏好存在差异,且这种差异还体现在需求者市场和供给者市场的对比中。 展开更多

Recent years, problems of the current college English courses, such as test-oriented teaching, wasteful duplication of language skills teaching, etc., have been criticized by educators and students in China. Thus, turning skill-based English courses into content-based ESP (English for Special Purposes) courses has become a tendency at colleges and universities in China. The purpose of this paper is to analyze factors influencing the design of such courses through the means of questionnaire, individual interviews, data survey (e.g., educational plans) etc.. We found the following factors throw light on the questions relating to curriculum design of ESP courses: (1) the learners' learning needs; (2) the social needs (esp. labor market needs); and (3) the academic needs from the university. The analysis serves to reveal the gap between the school system and actual social and students needs. With these factors in mind, designers of such courses can adjust goals, contents, approaches, and assessments in the practical teaching. And thus these factors would enable content-based ESP courses to reflect learners' needs better and lead to more effective langrage learning in college English teaching field. 展开更多
