Suggesting different player in many posts by an expert person is based on football experience, knowledge about the player and the club that he works. For mechanization the ability of this person, we use Expert System because it can model the ability of a person in solving a problem. Visual Prolog language is used as a tool for designing our Expert System.展开更多

Most importantly,within the professional and interpersonal relationship created between advisor and learner, it is easier to reflect on the emotional and affective implications of learning.This study explores the role of emotions and feelings in the learner’s and the advisor’s discourse,with the aim of shedding light on affect in autonomous language learning processes and thus helping language professionals to recognize and deal with affective issues as they arise. Based on audio-recordings and transcripts of individual advising sessions,the research design focuses on discourse analysis of the learners’ and the advisor’s discourse.The results show significant expression of emotions in the learner’s discourse,related both to past learning experiences and to planning further learning steps. In the advisor’s discourse,emotions are less apparent,as the advisor,rather,tends to mirror,empathize or counterbalance the learner’s emotions.展开更多

Nonetheless, we know very little about what these students think about advisors. Therefore,this study aims to investigate the perspectives these students may have on the role of advisors,enabling their learning needs to be better recognised and supported. This case study involves 120 masters’ students originally from China's Mainland on a pre-sessional course at a research institute in the UK,as well as students at the end of their one-year study, employing questionnaires and interviews to collect data.The results show that before the course,over 80% of the students reckon advisors are monitors to supervise them or advisors are teachers to teach them. However, throughout the course,the students gradually realize advisors play complex roles in developing students’ learner autonomy. Additionally, during the first week on the course, 62% of the students perceive learner autonomy as'to study by oneself, without others’ help'. Nevertheless, at the end of their one-year study, 75% of them perceive learner autonomy as'the attitudes and abilities toward life-long learning'. Overall, the findings indicate that the Chinese students’ transition to the British academic culture deepens their perceptions of learner autonomy, and bridges their gap between theory and practice of learner autonomy, but also helps them gain understanding of the complex nature of the advisor roles.展开更多
