Social network data to alleviate cold-start in recommender system: A systematic review     

Lesly Alejandra Gonzalez Camacho  Solange Nice Alves-Souza 《Information processing & management》2018,54(4):529-544

Recommender Systems are currently highly relevant for helping users deal with the information overload they suffer from the large volume of data on the web, and automatically suggest the most appropriate items that meet users needs. However, in cases in which a user is new to Recommender System, the system cannot recommend items that are relevant to her/him because of lack of previous information about the user and/or the user-item rating history that helps to determine the users preferences. This problem is known as cold-start, which remains open because it does not have a final solution. Social networks have been employed as a good source of information to determine users preferences to mitigate the cold-start problem. This paper presents the results of a Systematic Literature Review on Collaborative Filtering-based Recommender System that uses social network data to mitigate the cold-start problem. This Systematic Literature Review compiled the papers published between 2011–2017, to select the most recent studies in the area. Each selected paper was evaluated and classified according to the depth which social networks used to mitigate the cold-start problem. The final results show that there are several publications that use the information of the social networks within the Recommender System; however, few research papers currently use this data to mitigate the cold-start problem.  相似文献

Examining Minor League Baseball Spectator Nostalgia: A Neuroscience Perspective     

《Sport Management Review》2020,23(5):824-837

The purpose of this study was to explore nostalgia’s effect on MiLB spectators’ psychological, emotional, and behavioral responses. Mobile encephalography (EEG) headsets were used to monitor attendees’ neurological responses that may be indicative of nostalgia, while an ecological momentary assessment (EMA) permitted the capturing of spectators’ self-reported nostalgic levels. This approach allowed participants’ mental scores to be analyzed in relationship to their nostalgic occurrences. Brainwave frequencies emblematic of inward attention and arousal were significantly related with the number of instances spectators reported feeling nostalgic, which denote mental dispositions prevalent among attendees more prone to nostalgia. Moreover, PROCESS macro regression highlighted nostalgia’s ability to influence spectators’ behavioral intentions. Results also revealed environmental stimuli originating from sight, sound, and sociability to be especially prominent in triggering nostalgia. Overall, the study’s findings reveal unique characteristics present in baseball that render both immediate and enduring effects.  相似文献

Best of both worlds or refusal to comply? The rich kids of Tehran on Instagram     

Laura P. B. Partain 《Journal of International and Intercultural Communication》2020,13(3):216-237

ABSTRACT

This article offers a textual analysis and semiotic reading of the Rich Kids of Tehran's (RKOT’s) Instagram page. Contributing to scholarship on Iranian youth media practices, this article interrogates how the RKOT navigate urban and rural space to engage in everyday processes of resistance against global and local systemic oppression. Grounding their visual representations on Instagram in historical and cultural context, the author questions how and when quotidian actions are transformed into political transgressions when posted on social media. This article emphasizes the RKOT's agency in shaping their brand by analyzing representations of gender performance, intertextuality, and national identity on Instagram.  相似文献   

记忆场、传统村落与我们的责任——档案部门参与村落记忆场保护的价值与策略     

周林兴  林腾虹 《档案管理》2020,(3):39-41

传统村落拥有丰富的自然和文化资源,凝结着历史的记忆,是社会文明的直接见证者。随着城镇化进程的推进,传统村落逐步消融在时代的印迹里。为促进传统村落在新时代的焕发新生,文章借助法国历史学家皮埃尔·诺拉的记忆之场理论,指出传统村落在历史、时间、变迁中凝聚成具有象征意义的记忆场。在此基础上文章剖析了档案部门参与村落记忆场保护的意义,阐释了村落记忆场赓续乡村记忆、留住乡情乡愁、传承文化遗产的功能,并提出了档案部门就如何推动村落记忆场实现功能最大化的策略,以期使档案部门更好地承担起传承、保护、赓续传统村落的主体责任。  相似文献   

Making American Friends: The Effects of Musical Tastes and English Proficiency on Chinese International Students’ Social Networks in the United States     

Fei Jia  Emmanuel Koku 《Journal of Intercultural Communication Research》2019,48(1):4-20

This study investigated the relationship between Chinese international students’ social networks in the United States and their musical tastes. Based on concept of homophily, this study used a self-reported Social Network Analysis (SNA) survey to examine whether sharing similar musical tastes affected Chinese international students’ relationship, their musical tastes, and music consumption. The results showed that having high musical taste similarity predicted closer relationship between respondents and their alters, and higher likelihood of new music consumption. This study also found that frequent American English-language songs listeners were more likely to have Americans in their social network than less-frequent American English-language songs listeners.  相似文献   

Social identification,exercise participation,and positive exercise experiences: Evidence from parkrun     

Mark Stevens  Tim Rees  Remco Polman 《Journal of sports sciences》2019,37(2):221-228

Growing evidence suggests that social identities may have profound implications for physical activity participation. Real-world examinations of this relationship have, however, been lacking, with research predominantly examining intentions and hypothetical scenarios. To address this shortcoming and further advance understanding in this area, the present study tested relationships between group identification, participation, two exercise-specific outcomes (exercise-specific satisfaction and group cohesion), and a broad health indicator (life satisfaction) among individuals recruited from parkrun. Participants (N = 289) completed questionnaires measuring all variables except participants’ parkrun participation, which was objectively assessed. Structural equation modeling demonstrated that group identification was significantly associated with greater participation, exercise-specific satisfaction, group cohesion, and life satisfaction. Findings provide real-world evidence of the health-related benefits associated with forming strong social identities in exercise settings.  相似文献
