In the context of social media, users usually post relevant information corresponding to the contents of events mentioned in a Web document. This information posses two important values in that (i) it reflects the content of an event and (ii) it shares hidden topics with sentences in the main document. In this paper, we present a novel model to capture the nature of relationships between document sentences and post information (comments or tweets) in sharing hidden topics for summarization of Web documents by utilizing relevant post information. Unlike previous methods which are usually based on hand-crafted features, our approach ranks document sentences and user posts based on their importance to the topics. The sentence-user-post relation is formulated in a share topic matrix, which presents their mutual reinforcement support. Our proposed matrix co-factorization algorithm computes the score of each document sentence and user post and extracts the top ranked document sentences and comments (or tweets) as a summary. We apply the model to the task of summarization on three datasets in two languages, English and Vietnamese, of social context summarization and also on DUC 2004 (a standard corpus of the traditional summarization task). According to the experimental results, our model significantly outperforms the basic matrix factorization and achieves competitive ROUGE-scores with state-of-the-art methods.  相似文献   

The false dichotomy of message desirability in third-person effect scholarship     

David R Dewberry 《Qualitative Research Reports in Communication》2019,20(1):1-8

Meta-reviews of the third-person effect literature explain that scholars have assumed that certain messages are desirable or undesirable. In response, this study examines messages that vary in their social desirability so that we can better understand the specific characteristics of socially (un)desirable messages, how people account for changes in their perceptions of a message’s desirability, and the resulting behaviors from those perceptions.  相似文献   

Social equity and equity in higher education: A comparison of the liberal Anglo-American and Chinese political cultures     

《International Journal of Educational Development》2021

This study compares the ideas of social equity in the liberal Anglo-American and Chinese political cultures and seeks potential hybridisations. Through a conceptual examination of scholarly works, this study identifies differences and similarities of social equity between the two political cultures. A common conceptual bridge, deriving from the comparison and hybridisation, is further developed for the discussion of social equity and equity in higher education across the two cultures. The common bridge consists of four constitutes of social equity: political and civil equality, social and economic equality, equality of opportunity and equality of potential and freedom to achieve, the last of which is new hybridity of the two political cultures. This study argues that the hybridity – equality of potential and freedom to achieve – is enlightening to the discussion of equity in higher education as well as social equity across contexts.  相似文献   

The mediating role of moral exclusion between authoritarianism and outgroup discrimination     

《Int J Intercult Relat》2020

It has been well-documented that right wing authoritarianism and social dominance orientation as two facets of the authoritarian personality differentially account for a variety of negative intergroup behaviors. Integrating the Dual Process Model (Duckitt, 2001), with the literature on “Moral exclusion” (e.g., Opotow, 1990; Tileagă, 2007) we investigated whether or not moral exclusion would mediate such a relationship. Employing survey data (N = 1015), collected from a representative Hungarian sample, we found that moral exclusion mediated the effects of both RWA and SDO on the negative behavioral intentions against Roma as well as Jewish minorities in Hungary. Moreover, we argued that the concept of moral exclusion should be interpreted not as a generalized tendency, but as a mechanism which can be stemmed from distinct social cognitive motivations.  相似文献

What does it take to become “one of us?” Redefining ethnic-civic citizenship using markers of everyday nationhood     

《Int J Intercult Relat》2020

In this study we examined what are the markers of immigrant naturalisation as seen from the perspectives of recipient nationals. Social markers are perceptual signposts that receiving nationals use in deciding whether a non-native born is a member of the destination country. In short, what should immigrants do in order to be accepted by receiving nationals as “one of us”. Cross national data on 20 indicators of “everyday nationhood” were collected from five countries – Singapore, Japan, Australia, Finland, and Canada. The markers highlight common dispositions, activities, or social norms that are associated with citizenship. Exploratory factor analysis in each sample consistently demonstrated a two-factor structure model that supports the contemporary ethnic-civic distinction, but the markers that make up each of the two dimensions vary between countries. No metric equivalence was found, and that the markers have culture-specific meanings. The framework offers a novel insight to intercultural relations. The results suggest that adaptation and social inclusion need to consider the norms and values practised in the recipient society, and how immigration may redefine intergroup boundaries.  相似文献

Setting the future of digital and social media marketing research: Perspectives and research propositions     

《International Journal of Information Management》2021

The use of the internet and social media have changed consumer behavior and the ways in which companies conduct their business. Social and digital marketing offers significant opportunities to organizations through lower costs, improved brand awareness and increased sales. However, significant challenges exist from negative electronic word-of-mouth as well as intrusive and irritating online brand presence. This article brings together the collective insight from several leading experts on issues relating to digital and social media marketing. The experts’ perspectives offer a detailed narrative on key aspects of this important topic as well as perspectives on more specific issues including artificial intelligence, augmented reality marketing, digital content management, mobile marketing and advertising, B2B marketing, electronic word of mouth and ethical issues therein. This research offers a significant and timely contribution to both researchers and practitioners in the form of challenges and opportunities where we highlight the limitations within the current research, outline the research gaps and develop the questions and propositions that can help advance knowledge within the domain of digital and social marketing.  相似文献   

Identifying the combinations of motivations and emotions for creating satisfied users in SNSs: An fsQCA approach     

《International Journal of Information Management》2020

Social Networking Sites (SNSs) play an important role in our daily lives and the number of their users increases regularly. To understand how users can be satisfied in the complex digital environment of SNSs, this study examines how motivations and emotions combine with each other to explain high satisfaction. Users’ motivations comprise four attributes, entertainment, information, social-psychological, and convenience. Emotions are divided into their two main categories, that is positive and negative emotions. We draw on complexity and configuration theories, present a conceptual model along with propositions and perform a fuzzy-set qualitative comparative analysis (fsQCA). Through an empirically study with 582 SNSs users, we present eight combinations (configurations) of motivations and emotions that lead to high satisfaction, which highlight the role of high convenience, followed by entertainment and information motivations in being satisfied with SNSs. High satisfaction can be achieved both when positive and negative emotions are high and low, depending on how they combine users’ motivations. None of the factors are indispensable to explain high satisfaction on their own, instead they are insufficient but necessary parts of the causal combinations that explain high satisfaction. This study contributes in SNSs literature by extending current knowledge on how motivations and emotions combine to increase satisfaction, and by identifying specific patterns of users for whom these factors are important and influence greatly their satisfaction.  相似文献
