Problematisation Previous study has indicated that social media is an effective marketing tool. Moreover, Weibo, a Chinese social network contains large potential for the companies. However little theoretical guidance exists on what are the key features of Weibo marketing. Purpose and research question The purpose of this study contributes to a better understanding of the social media by analyzing the advantages and disadvantages of Weibo for Western companies that expect to launch a successful marketing strategy. Methodology This research is done through qualitative approach and is of an abductive nature . It uses a case-study methodology and relying on empirical data and theoretical conceptions. The main empirical findings are based on collection of 13 personal  interviews. Results and conclusion The result of this paper contributed to deep understanding of Weibo marketing. Therefore, the theoretical guideline in form of model has been developed and includes 8  key features (4 advantages and 4 disadvantages) that should be considered by Western companies in order to apply successful marketing strategy on Weibo.

Nous proposons de concevoir et développer un outil permettant d’analyser la diffusion d’information sur les services de réseaux sociaux en ligne grâce au traitement et à la visualisation de données. Fruit d’une réflexion méthodologique, ce dispositif permet d’observer les relations entre les dimensions conversationnelles, sémantiques, temporelles et géographiques des actes de communication en ligne. Courts messages se propageant rapidement sur la Toile selon des modèles encore mal connus, les mèmes Internet comptent parmi les contenus les plus prisés sur les plate-formes web. Les mèmes Internet circulant sur le service de microblog chinois Sina Weibo articulent notamment discussions personnelles, débats sociétaux et vastes campagnes médiatiques. Mobilisant des méthodes issues de l’analyse des réseaux et du traitement automatisé de la langue chinoise, nous procédons à l’analyse d’un vaste corpus de 200 millions de messages représentant l’activité sur Sina Weibo durant l’année 2012. Notre première tâche consiste à identifier des mèmes dans ce large ensemble de données. L’identification de mèmes dans un ensemble de messages est notamment possible grâce à un algorithme de détection non supervisé. Néanmoins, le volume de calculs nécessaires pour obtenir des résultats fiables sur un large corpus nous amène à abandonner cette approche, montrant par là-même la complexité d’une définition intéressante de l’objet numérique composite mème. Notre seconde série d’analyses porte sur le volume de conversations entourant les hashtags du corpus. Les résultats montrent que les usages majoritaires de Sina Weibo sont similaires à ceux des médias traditionnels (publicité, divertissement, loisirs...). Néanmoins, nous écartons les hashtags comme représentants des mèmes Internet, artefacts d’usages commerciaux et stratégiques à la diffusion cadrée et planifiée. L’approche finalement retenue utilise la recherche par mots-clés pour constituer les corpus de messages décrivant une dizaine de mèmes sélectionnés dans la littérature académique et secondaire pour leurs intentions diverses : humour, actualité, scandale politique, faits divers et marketing promotionnel. S’inspirant de la critique des schémas théoriques de communication, une analyse des mots et des réseaux d’échanges entre utilisateurs met à jour les dynamiques discursives de chaque mème. L’organisation de ces informations selon un axe temporel dans un espace de visualisation interactif autorise une lecture détaillée de leur diffusion. La projection de ces réseaux conversationnels et lexicaux sur des cartes géographiques montre également les relations entre leurs aspects textuels et actuels. Les figures obtenues permettent d’ébaucher une typologie structurelle de la diffusion de ces contenus, montrant comment différents régimes d’expression cohabitent sur les réseaux sociaux. La tension entre énonciation et discours qui régit les plateformes Web se manifeste dans des motifs particuliers de circulation des contenus en ligne. Nous pouvons ainsi formuler des recommandations pour l’analyse et la conception de stratégies de communication en ligne d’organismes tant privés que publics. Néanmoins, le caractère exploratoire de cette étude et la difficulté de comprendre les actions humaines par une simple analyse de données nous invite à refuser une généralisation a priori des résultats, préférant considérer ce travail comme la première validation d’une méthodologie pouvant être étendue à d’autres formes de conversations en ligne. / We develop a data mining and visualisation toolkit to study how the information is shared on online social network services. This software allows to observe relationships between conversational, semantical, temporal and geographical dimensions of online communication acts. Internet memes are short messages that spread quickly through the Web. Following models that remain largely unknown, they articulate personal discussions, societal debates and large communication campaign. We analyse a set of Internet memes by using methods from social network analysis and Chinese natural language processing on a large corpus of 200 million tweets which represents/reflects the overall activity on the Chinese social network Sina Weibo in 2012. An interactive visualisation interface showing networks of words, user exchanges and their projections on geographical maps provides a detailed understanding of actual and textual aspects of each meme spread. An analysis of hashtags in the corpus shows that the main content from Sina Weibo is largely similar to the ones in traditional media (advertisement, entertainment, etc.). Therefore, we decided to not consider hashtags as memes representatives, being mostly byproducts of wellplanned strategic or marketingcampaigns. Our final approach studies a dozen of memes selected for the diversity of their topic: humor, political scandal, breaking news and marketing.

Among the web 2.0 applications, a micro-blog (Weibo in Chinese), resembling the combination of a Twitter-like Internet service has gained substantial popularity in China. Sina Weibo is the market leader with approximately 50% of the market share. Around 80% of the users on Sina Weibo are young people. Hence, it is necessary to analyze young Chinese users of Sina Weibo and examine whether Sina Weibo fulfills the needs of young people and whether Sina Weibo meets their expectations. The study used the theory of uses and gratifications and the theory of expectancy-value as theoretical foundations. This study summarized six gratifications items (including social interaction, social networking, information seeking, information sharing, entertainment and recognition) from previous studies, and used these gratifications items to analyze: (1) the relationships between demographics and gratifications obtained; (2) the relationships between Sina Weibo usage and gratifications obtained: (3) the correlations between gratifications sought and gratifications obtained. This study used quantitative method to obtain data from a questionnaire and all the data were input to SPSS (Statistical Package for Social Science) for analyzing. The questionnaire was conducted and was distributed in Sojump.com. The results showed that Sina Weibo meets their users’ needs from six gratifications dimensions.

The rapid rise and popularization of social media has a profound impact on the society today. The emergence of the social media broadens the channels of communication and the people's vision. Citizens can freely express information such as words and pictures, and freely exchange their views on social media. This study will focus on Sina Weibo which is the most popular social media in China. The purpose of this research is to study how to attract so much attention by protagonist‘s post and this certain hot event. Simultaneously, it also focuses on attitude and opinions of audience through the comments of this incident. This research aims to do rhetoric analysis and content analysis by selecting the most popular posts and top 100 hot comments. It is interesting to discover that the most feasible ways of attracting attention are creating emotional response, strengthening credibility and persuading in rational approach. This event has received most of the audience support. The audience expressed their concern and compassion towards this event. They share the valuable information in the comments to express their feelings. However, there still exist some different opinions on it. Although it is hard to guarantee the same attitude of the spectators, the huge number of audience on Micro-blog is an important factor in the rapid spread of this event.

As the name suggests and according to the developers’ intention, Social Networking Sites (SNS) are designed as tools for users to make friends and express themselves. However, the usage of SNS apparently goes beyond these aspects with more plurality and possibilities unforeseen by their conceivers. Much evidence shows that communicating about the environment and nature on social networking sites is a prominent phenomenon. However, few researchers have shed light on the individual use of SNS for environmental communication. Individuals in both China and Sweden generate, seek, disseminate and discuss environmental news and information on SNS. This exploratory study employs qualitative methods to examine this practice and compares the differences and similarities between Chinese and Swedish individuals in terms of environmental communication. Focusing on motivation and engagement, the study explains and describes why and how individuals in these two countries are engaged in environmental communication. The study also examines the social and political implications of this phenomenon by discussing the relationship among new technology, communication and social changes.

The primary goal of this study is to observe how the meaning of nostalgia is negotiated and remediated in Li Ziqi’s short videos, and understand the construction and expression of pastoral images in the video, by examining its social modality of the audiencing site and the compositional and social modalities of the image site through a Critical Visual Approach(CVA). Except for CVA, Remix as a thinking tool helps to frame data selection, mixed methods and theories throughout. To be specific, the aim of this study is to examine Li Ziqi’s communication of nostalgia online via short videos, showcases how the pastoral characteristics are evoked in the videos and the relationship between nostalgia of pastoral life and short videos. Moreover, it is of interest to think about what nostalgia communication on short videos say about society. When it comes to the two sites, firstly, an ethnographic method of thick descriptions is used to study media text and selected comments on the audiencing site. Secondly, on the image site, compositional analysis on selected visual materials is used to examine its compositions and then signs and meanings embedded in them are analyzed through semiotic analysis and interpreted by thick descriptions. As for theories, nostalgia and media, the logic of social acceleration, remediation and new media, and simulacra and simulation are applied to facilitate discussion.
