Combining different evaluation systems on social media for measuring user satisfaction     

Simona Balbi  Michelangelo Misuraca  Germana Scepi 《Information processing & management》2018,54(4):674-685

Web 2.0 allows people to express and share their opinions about products and services they buy/use. These opinions can be expressed in various ways: numbers, texts, emoticons, pictures, videos, audios, and so on. There has been great interest in the strategies for extracting, organising and analysing this kind of information. In a social media mining framework, in particular, the use of textual data has been explored in depth and still represents a challenge. On a rating and review website, user satisfaction can be detected both from a rating scale and from the written text. However, in common practice, there is a lack of algorithms able to combine judgments provided with both comments and scores. In this paper we propose a strategy to jointly measure the user evaluations obtained from the two systems. Text polarity is detected with a sentiment-based approach, and then combined with the associated rating score. The new rating scale has a finer granularity. Moreover, also enables the reviews to be ranked. We show the effectiveness of our proposal by analysing a set of reviews about the Uffizi Gallery in Florence (Italy) published on TripAdvisor.  相似文献   

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   

The role of student–university value alignment in international student acculturation in Australia     

《Int J Intercult Relat》2021

This study integrates acculturation and person–environment fit theories to investigate the role of student–university value alignment in international student cross-cultural adjustment to host universities in Victoria, Australia. The study used a mixed methods design with the quantitative data collected from a student survey and the qualitative data generated from interviews with university staff. Structural equation modelling and thematic analysis were employed to analyse the quantitative and qualitative data respectively. The results of the study indicated that international students who possess similar values to their host university, adjust better, both psychologically and socially into the university environment as well as feel satisfaction with their host university. The study also confirmed the mediating role of international student social adjustment in the relationship between student–university value fit and student overall satisfaction with their host university. The findings highlight the key role of international student–university value alignment in contributing to the success of students’ cross-cultural adjustment to the new cultural environment they experience. Therefore, universities should constantly communicate and deliver on their values during both the promotional stage of international student recruitment and the student journey with the university.  相似文献
