基于共现分析的网络议程设置研究从认知心理学的角度出发,分析媒体议程与公众议程网络,更加贴近回答李普曼所说的“我们脑海中的图景”,但该方法只能体现议程网络中关键词间的显性关系。本文提出通过基于上下文语义的word2vec模型,测度网络议程设置中关键词隐性关系的研究方法。以“红黄蓝事件”为例,揭示党媒、都市类媒体、商业媒体、知乎意见领袖以及公众的议程网络及其相似度。研究发现,知乎意见领袖对公众议程的影响程度最大,其议程主要是对事件背后因果关系的梳理以及对策建议的提供。在媒体方面,党媒和都市类媒体报道基本一致,且二者对公众的影响均高于商业媒体。本研究是对现有网络议程设置研究的补充,对议程设置的本土化研究有一定的启示。 相似文献

议程设置理论与后大众媒体时代的民意研究 总被引：4，自引：0，他引：4
关于媒体与民意的理论大部分提出于 1 93 0到 1 980年之间 ,这是一个仅仅拥有传统信息选择方式的时代。麦库姆斯和肖 (1 972 )最初提出议程设置理论时 ,用北卡罗莱纳州的教堂山 (ChapelHill)社区作为研究对象 ,而现在那里的媒介使用情况也已经发生了巨变。当我们迎来议程设置理论提出 3 0周年的时候 ,教堂山的受众现在面临的信息选择令人惊叹。在 2 0世纪 90年代 ,肖提出 ,美国的大众媒介已经经历了“兴和衰”(riseandfall)。肖认为 ,大众媒体时代结束于 2 0世纪 80年代。议程设置研究是否能像之前的 3 0年那样 ,继续开展下去 ?当受众使用着上百个信息来源时 ,议程设置和民意研究会产生何种变化 ?这是本文将要回答的问题 相似文献

This study examined whether the candidate-controlled public relations tools of political ads and candidate blogs were successful in influencing the issue and news agenda of the major television news networks during the 2004 presidential election. Data showed strong correlations between blogs and the media agenda. Advertisements did not correlate with the media agenda. Cross-lag analyses showed that the media set the candidates' agenda. The authors suggest intermedia agenda setting occurred as the media transferred their agenda to campaign blogs. 相似文献

Social network analysis (SNA) as theoretical framework and quantitatively oriented methodology offers public libraries and public library researchers an as-yet-unexplored way into their big data stories based on these library connections with their community. SNA offers library and information science researchers a methodology, and suggests a new research agenda, to better envision the relationships public libraries have with their communities both in-person and online by exploring the kinds of ties they have, how these ties lead to relationships, and how these relationships can be characterized. The quantitative orientation of SNA combined with its methods of data analysis in the forms of networks and hubs could give libraries the “hard” data they are so often in need of to demonstrate their value to their political leaders, and could uncover new directions in library use and library relationships. 相似文献

This research investigates the communication behavior and engagement strategies in the bilateral use of social media between law enforcement agencies and the communities they serve. It advances existing work by studying municipal level government actors in a new communications environment where social media now play an important part. Grounded in agenda setting theory, our analysis identifies police departments' social media issue priorities, analyzes the responses of their audiences to those communications, and directly compares followers' own conversation priorities with the police agenda. Our data set includes all the content from the Facebook and Twitter accounts of five similarly sized and demographically situated police departments in the U.S., plus all the tweets and posts from the followers or friends responding to those accounts over a 90-day period. We performed both manual coding and machine cluster analysis to elicit major threads of conversation. In addition to the data analytics, we conducted interviews with the five police departments to understand the similarities and differences in agenda priorities resulting from their social media goals and use.The study shows the priorities that comprise the police agenda, identifies both similarities and differences in what their audiences communicate among themselves about most frequently in the public safety domain relative to the police agenda, and finds evidence of positive response from the public to some of the agenda priorities communicated by the police. Our data also reveal that police are using social media interactively, which could, over time, advance community policing goals. The paper concludes by considering the implications of these findings for law enforcement and community policing and suggests directions for future research on agenda setting in this new media environment. 相似文献

Community structure research investigates the influence of the local community and specific demographic groups in the community on the degree of emphasis that particular public issues receive in a local newspaper. In contrast to this internal source of influence, intermedia agenda setting emphasizes the external influence of other news media and the national journalistic culture on the news decisions of local daily newspapers. To invoke a cliché, the agenda-setting and community structure perspectives are opposite sides of the same coin and should be considered in tandem. The research design and procedure for statistical analysis presented here, which involves the simultaneous investigation of the influence resulting from community structure and intermedia agenda setting, is a path for new research that can present a detailed explication of the balance between local and national influence on the issue agenda of local daily newspapers. 相似文献

Through two separate studies in the context of Hong Kong, a Chinese society, this research tests the third-level agenda-setting effects and examines the differences between the explicit and implicit public agendas based on the attributes consciously and unconsciously reported by the public. A total of 1667 news reports and 680 responses to a public survey are collected for analysis. Evidence from both studies shows strong attribute agenda-setting effects at the third level, no matter the focus of the issue is obtrusive or unobtrusive. Results also demonstrate that the media agenda is positively associated at a higher level with the implicit public agenda than the explicit one. Findings well extend the network agenda-setting research. 相似文献

The extent to which nationalist discourse is transferred between the authority and the people remains unclear. Taking Chinese nationalism on Weibo as a research context, this study differentiated Weibo accounts into (1) individual users, (2) influencers, and (3) organizational accounts, and it applied a network agenda-setting (NAS) approach to analyze how nationalist issues are transferred among different actors. Based on large-scale data, supervised machine learning was employed to identify issue categories, while semantic network analysis was completed to construct issue networks. The results indicate that media agenda influences individuals’ agenda while the construction of nationalism follows a bottom-up direction. 相似文献

浅析网络议程设置的特色 总被引：11，自引：0，他引：11
议程设置理论的提出基于传统媒体环境。强有力的传播者、处于被动状态中的受众和传统媒体的有限性为实现媒介的议程设置提供了主、客观的保障。然而 ,网络中传播权泛化、信息获取高度自由、时空无限将“议程设置”理论的传统基础一一打破。但打破并不意味着网络不能设置议程。本文分析了网络传播中议程设置在议题设置者、议题内容及议题设置所依赖的技术三方面不同于传统媒体的特色。 相似文献

Humanities and social sciences require new research approaches to deal with and to benefit from the explosion of digital media. Thanks to large scale data storage and processing, close reading of individual items can be supplemented with analysis of broader trends from massive amounts of data. Cultural Analytics (CA) is a recently developed methodology for the exploration of content and visual form in large image and video collections. It has already been applied to a variety of media types, including TV programs, feature films, newspapers, and video games. However, until now these applications did not take into account the social context of media. In many cases, media artifacts under scrutiny are generated or used by people in a social setting, either in forms of (digital) communities, or in terms of social relations, which can be also analyzed as a valuable source of information. Social network analysis (SNA) is a set of methods for the analysis of human networks, including massive online social networks. In this article, we argue that CA and SNA can be combined synergistically, using data and images from deviantArt, the leading online network of user-created art, as a case study. 相似文献

This article examines how South Korean and Japanese public diplomacy organizations employ digital media to embrace the principle of ‘networked public diplomacy’ through analyses of the web and social media practices. A network analysis was used to map interorganizational information networks among core public diplomacy organizations in each country. To reveal the key organizations' communication strategies on Facebook, a content analysis was also conducted. The findings indicate that Japan had a strong internal network infrastructure achieved through dispersed connections and partnerships; however, Korea had a centralized network, including a limited number of dominant actors. The results of content analysis suggest that both South Korea and Japanese public diplomats focused on promoting their cultural products and national values through their use of texts and visual images. In addition, user profile analysis gaged the degree of users' engagement in the organizations' profiles and identified the demographic features of users. Comparative data suggest the Korean public diplomacy organization was more successful at attracting and engaging with foreign public than the Japanese public diplomacy organization. These results imply that although these two countries had similar sociopolitical backgrounds and perspectives of public diplomacy, they had distinct forms of internal information networks, communication strategies, and social networking performances with public. 相似文献

Despite the expectation that social media use in the public sector contributes to enhancing government responsiveness to citizens, few empirical studies exist on whether social media use actually leads to more responsive public administration in practice and how social media are used by governments to build citizen-centric governance. The purpose of this study is to examine what roles are played by mayors and public officials in social media networks to increase government responsiveness. Thus, we adopt social network analysis (SNA) to the Twitter network of public services as well as carry out a case study on interactions among the mayor, local government, and citizens via Twitter in Seoul, Korea. The research findings show that the mayor of Seoul plays the most important role as a bridging hub in the Twitter network. Specifically, the mayor serves as a bridge between different clusters of citizens and public officials as well as a hub for the most connected users in the network. The mayor's role as a bridging hub in the Twitter network contributes to enhancing government responsiveness by making possible to overcome the disconnection between citizens and the local government, and information asymmetry among the mayor, public officials, and citizens. 相似文献

This article applies a network metaphor to an examination of the mediated public sphere. The analysis focuses on the deliberative spaces afforded by traditional and alternative media technologies, concluding that participatory digital technologies best support interactive and adaptable networks for deliberation. These networks sustain enclave and shared nodes where multiple publics can engage in deliberation within and across public boundaries. This argument informs decisions regarding broadband policy by focusing attention on values of openness, access, and freedom. 相似文献

Based on agenda‐setting research, this study focused on the links between media coverage, real‐world indicators, and public opinion about abortion. We conducted a content analysis of coverage of the abortion issue in two prestige newspapers, The New York Times and the Washington Post, between two key Supreme Court rulings. We hypothesized that amount of coverage would (a) increase during election years, (b) be related to number of abortions performed, and (c) be related to public opinion about abortion rights. We found mixed support for our hypotheses. Abortion coverage did peak during election years but was not related to the number of abortions performed, and was related negatively to public acceptance of abortion rights. 相似文献

Intermedia agenda setting predicts a high degree of convergence between news media agendas. However, the rise of social media forces a re-examination of this expectation. Using the 8.8-earthquake of February 27, 2010 in Chile as a case study, this article compares which topics were covered by professional journalists on broadcast news and Twitter, analyzing both cross-sectional and longitudinal trends. A positive, reinforcing influence was found among the journalistic agendas of TV and Twitter. However, counter to the idea that social media are echo chambers of traditional media, it was found that Twitter influences TV news more so than the other way around. Thus, the study provides an early lens into the agenda setting function of social media among television news professionals, and its findings are consistent with Twitter succeeding among journalists due to its provision of valuable information. 相似文献

As agenda-setting theory moves toward its 50th anniversary, its productivity in the past and at present augurs a highly promising future. In this essay, the original theorists trace the development of agenda setting and identify seven distinct facets. They explore three of the seven facets—need for orientation, network agenda setting, and agendamelding—in greater detail because those are particularly active arenas of contemporary research. Grounded in more than 40 years of productive collaboration among the authors, this inaugural Deutschmann Scholars Essay offers numerous new ideas about recent trends in and future directions for agenda-setting theory and research. The three authors are all recipients of AEJMC's Paul J. Deutschmann Award for Excellence in Research recognizing a career of scholarly achievement. The Deutschmann scholars observed that this may well be the most original article they have ever written together. 相似文献

This study examined the relationship between different media agendas and public agendas in the agenda‐setting process. The local and regional media agendas for environmental news in the Lansing, Michigan, area were exactly the same. It was also found that respondents could accurately assess media issue emphasis when they were asked to do so. 相似文献

This article provides a systematic overview and conceptual analysis of existing research on brands and branding in the literature on media management. The aim is to advance knowledge in the field by mapping out the different ways in which brands are understood and conceptualized in the literature. In doing so, the article identifies overlooked research areas and works toward a research agenda for future scholarly research on the topic. Overall, it is argued that the further development of the area calls for a more systematic theoretical analysis of the nature of media brands and the specific features and complexities of the media field as a strategic business environment where brands are built and managed. The development of the research area would seem to be crucial not only for scholarly reasons, but also because strong brands seem to be gaining strategic value and importance in today’s changing and highly competitive media markets. 相似文献

This study examines the triangular relationship of the press,the president and public opinion about the drug issue in theUnited States from 1985 to 1990. Agenda-setting theory servesas the theoretical foundation for the ARIMA time-series analysis,which attempts to address who is driving the public opinionformation process about drugs: the press, the president, orthe public. The study employs a unique method in that ‘mostimportant problem’ survey results from nine organizationsare quilted into a time-series of 70 monthly points to measurethe public agenda. The press agenda is based on a computerizedcontent analysis of the frequency of coverage of the drug issue,and the presidential agenda is based on a similar analysis ofthe presidents’ public relations agendas. The three univariatetime-series are identified, estimated, and diagnosed. Then thewhite-noise component of each is used in a cross-correlationanalysis to address the research question. The results indicatethat public opinion mirrors or immediately follows the press,though public opinion also drives the press agenda. Second,the study suggests that the president is following the publicagenda, though the president also has strong immediate influenceon public opinion. And, finally it suggests the president mirrorsand follows the media, in addition to following public opinion.The trend of opinion, when viewed in relation to the historyof events surrounding the issue, suggests that the public opinionformation process, as measured through the lens of public opinionpolls, may be a matter of public perceptions of the realityof the issue and of the pseudo-realities of information campaignsand presidential and press attention, which may have their originsback in the heart of the public concern. 相似文献
