BBS(Bulletin Board Systems) is one of the most common places for threaded discussion. It becomes more and more popular among web users, especially in China. Everyday a huge amount of new discussions are generated on BBS. It is too difficult to find hot topics. To solve this issue, we propose a novel approach to detect hot topics on BBS for any period of time. Our solution consists of three step...

Initiation, Response, and Feedback(IRF) sequences are the most frequent interaction network in any classroom contexts. IRF sequences have been examined profusely in previous studies and were reported to be negatively correlated with participation opportunities (Kasper, 2006; Cazden, 2001; Ellis, 1994).In all these studies, all contingent factors of any classroom context which might influence in...

Despite the abundance of research investigating general and academic vocabularies and developing dozens of word lists, few studies have compared academic vocabulary with general service word lists such as conversation vocabulary. Many EAP researchers assume that university students need to know all the words in West’s (1953) General Service List (GSL) as a prerequisite to academic words (e.g., ...

Discussions on social Web platforms carry a lot of information which is more and more difficult to analyze. Given a virtual community of users that discuss a particular topic of interest, an important task is to extract a model of the whole debate in order to automatically evaluate what are the most reliable claims. This paper proposes to approach this task using abstract argumentation, and def...

teacher questions are claimed to be constitutive of classroom interaction because of their crucial role both in the construction of knowledge and the organization of classroom proceedings (dalton puffer, 2007). most of previous research on teachers’ questions mainly focused on identifying and discovering different question types believed to be helpful in creating the opportunities for learners’...

Despite the abundance of research on teachers’ repair practices in language classroom interaction, there are not enough conversation analytic studies on repair organization with the focus on the details of interaction in the context of EFL. Drawing on sociocultural and situated learning theories, this study explores the contingent nature of English language teachers’ org...

This study aims at empirically furthering awareness of the organization of interaction in EFL classes. Informed by the methodological framework of conversation analysis, it draws upon a corpus of 52 three-hour naturally-occurring classroom interaction to identify classroom interactional contexts based on the structuring of the pedagogic goals in turn-taking sequences. Conversation analytic proc...
