Tracking user-role evolution via topic modeling in community question answering     

Chaogang Fu 《Information processing & management》2019,56(6):102075

Community question answering (CQA) services that enable users to ask and answer questions are popular on the internet. Each user can simultaneously play the roles of asker and answerer. Some work has aimed to model the roles of users for potential applications in CQA. However, the dynamic characteristics of user roles have not been addressed. User roles vary over time. This paper explores user representation by tracking user-role evolution, which could enable several potential applications in CQA, such as question recommendation. We believe this paper is the first to track user-role evolution and investigate its influence on the performance of question recommendation in CQA. Moreover, we propose a time-aware role model (TRM) to effectively track user-role evolution. With different independence assumptions, two variants of TRM are developed. Finally, we present the TRM-based approach to question recommendation, which provides a mechanism to naturally integrate the user-role evolution with content relevance between the answerer and the question into a unified probabilistic framework. Experiments using real-world data from Stack Overflow show that (1) the TRM is valid for tracking user-role evolution, and (2) compared with baselines utilizing role based methods, our TRM-based approach consistently and significantly improves the performance of question recommendation. Hence, our approach could enable several potential applications in CQA.  相似文献   

Problematizing the absent girl: sport as a means of emancipation and social inclusion     

David Ekholm  Magnus Dahlstedt  Julia Rönnbäck 《Sport in Society》2019,22(6):1043-1061

Abstract

Absence from sport participation among girls from ethno-cultural minorities is often highlighted as an inclusion policy challenge. Based on 35 interviews with community sports coaches, managers and partners, we explore how the absence of girls is problematized in four Swedish sports-based interventions, focusing on how problems, as well as the means and the ends of social inclusion, are articulated. The girls are assessed as being in need of social change due to their alleged social exclusion. Absence is explained by “patriarchal norms” as well as by the introvert conduct of the girls themselves. Girls-only sports activities performed by female coaches as role models are described as a way for girls to gain social inclusion and to become emancipated from subjugating norms. In conclusion, participation in community sport is highlighted in discourse as crucial for adopting powers of emancipation. A similar discourse could be recognized elsewhere, inside and outside the realm of sport.  相似文献   

Engagement in dialogue: tracing our connections or speaking across the space between?     

Leslie Maurice Alford 《Educational Philosophy and Theory》2018,50(5):448-454

Abstract

In this paper I contrast conceptions of self from two perspectives: an individualistic orientation and a communitarian approach. In doing so, the philosophical justification is Wittgenstein’s idea that individualism is produced and reinforced as a way of being, thinking and interacting in community. With this contextual frame, I argue that we are shaped by the language practices of our community to ascribe meaning and interpret our own relationships with others through our language lexicon and grammar. To illustrate the communitarian perspective I refer to Māori perspectives in which connectedness is axiomatic: in particular the concepts of whanaungatanga and whakapapa, as described by Ka’ai and Metge. On the basis that such concepts are predicated on language use, I suggest that we can learn the grammar of engagement in a discursive context that emphasises connectedness just as easily as in one which is founded on separateness. I argue that interacting with an other is to engage with the ideas, beliefs, and values that shape their language, even as we expose our own. Engaging between individualistic and communitarian understandings is presented as learning to bridge language gaps between different social constructs and understandings of reality.  相似文献

目前,幼儿入园前教育形式主要有三种:家庭教育、机构教育和社区教育。但现实困境是,很多家庭的幼儿入园前未能较好地接受到任何一种形式的教育。对此,有一些可行的创新策略,分别为成立“社区活动小组”、邀请早教机构送教入小区、利用互联网共享优秀教育活动、依托附近幼儿园资源不定期举办亲子活动、社区提供亲子活动空间和人力参与互动等。  相似文献   

“非遗”传承的困境和电大社区教育的意义     

韩冬梅  宋敏 《继续教育研究》2021,(2):58-62

从甘肃省的"非遗"传承来看,确实有诸多困境,这些困境都指向了"传承人"的问题,即后继乏人。因此,有必要研究从根本上解决"非遗"传承人的问题。文化的传承需要教育,教育要学校来办。电大社区教育能汇聚最优质的教师队伍和最优质的教学资源,能较好地解决"非遗"传承人的教育问题,且能对广大民众进行传统文化的教育,唤起民众对"非遗"保护的自觉意识。通过将电大社区教育跟"非遗"项目逐渐对接,可以从根本上解决"非遗"传承人的问题,从而摆脱"非遗"传承的困境。因此我们得出的结论是:"非遗"传承的问题是"传承人"后继乏人的问题,解决"传承人"的根本办法在教育,电大社区教育是解决"非遗"传承人教育的良好选择。  相似文献   

专业社会工作机构参与村改居社区教育研究——基于B县益仁社区的实践     

王德林 《继续教育研究》2021,(2):54-57

与农村社区和城市社区相比,村改居社区的社区教育在教育内容、教育形式上有其特殊性。通过参与式观察的方法研究专业社工机构在提供社区服务的过程中对益仁社区的社区教育的作用,发现专业社工机构在村改居社区村民到市民的角色转变、重构社区文化、特殊群体的社区教育和社区自组织的培育上做出了一定贡献,但专业社工机构在参与村改居社区教育过程中也存在社区治理与社区教育的联动有待加强、专业社区教育力量亟须补充、社区内外社区教育资源的利用需要加强、社区居民的参与度需要提高等问题。  相似文献
