No. of bitstreams: 1 2017_ChristianeTegethoffMottadeAraujo.pdf: 3363824 bytes, checksum: 8231a05bd0d937fa03e30d1163553599 (MD5) Previous issue date: 2018-07-10 / Esta pesquisa tem como propósitos investigar o sinal gráfico # sob uma perspectiva linguística e social, elucidar os contextos de uso do símbolo e refletir sobre as suas funções sociais e discursivas. Ademais, o estudo procura compreender os motivos pelos quais os usuários utilizam a hashtag para compor mensagens. O corpus é formado por dezoito textos coletados aleatoriamente e extraídos do ambiente virtual e real. O referencial teórico teve como base a Análise de Discurso Crítica (ADC) de Fairclough (2001 e 2003), Chouliaraki e Fairclough (1999) e van Dijk (2011). A metodologia é qualitativa e apoiada em Bauer e Gaskell (2015). As categorias analíticas seguem a literatura da ADC, complementada pela Pragmática (AMENGAUD, 2006; WILSON, 2008; VOGT, 1980), pela Linguística Funcional Centrada no Uso (CEZÁRIO, 2013; MARTELLOTA, 2011; NEVES, 2013) e pelos estudos sobre ideologia de Thompson (1995). Os resultados revelaram que a hashtag é um recurso semiótico que pode ser selecionado de acordo com a conveniência do usuário em cada situação comunicativa. O recurso # pode desempenhar vários papéis no discurso. Mais especificamente, o símbolo hashtag: confere intensidade ao conteúdo semântico do texto, acrescenta contexto à mensagem, promove ambient affiliation, constrói as identidades dos indivíduos, sugere adesão à mobilização social, transforma ato ilocutório em ato perlocutório, dissimula estratégias de marketing, e, por fim, serve à sociedade hegemônica por meio da manipulação de informação. O uso da hashtag em textos indicia as mudanças pelas quais a sociedade tem passado no âmbito da comunicação e representa a aceitação e difusão de novas práticas sociais e discursivas contemporâneas. / This research aims to investigate the graphic sign # under a linguistic and social perspective, to clarify the symbol’s utilization contexts, and to reflect on its social and discursive functions. Moreover, the study tries to understands the reasons why users choose hashtag to create messages. The corpus comprises eighteen randomly collected texts from virtual and real environments. The theoretical framework is based on Critical Discourse Analysis (CDA) as in Fairclough (2001 and 2003), Chouliaraki and Fairclough (1999), and van Dijk (2011). The methodology is qualitative and supported by Bauer and Gaskell (2015). The analytic categories follow the CDA literature, complemented by Pragmatics (AMENGAUD, 2006; WILSON, 2008; VOGT, 1980), Usage-Based Linguistics (CEZÁRIO, 2013; MARTELLOTA, 2011; NEVES, 2013) and the studies on ideology by Thompson (1995). Results show that the hashtag is a semiotic resource that can be chosen according to the user convenience in each communicative situation. The resource # may perform multiple roles in discourse. In particular, the hashtag symbol: intensifies the semantic content of the text, adds context to the message, promotes ambient affiliation, builds user identities, suggests that other people join social mobilization, changes illocutionary acts into perlocutionary acts, dissimulates marketing strategies, and finally, it serves the hegemonic society by manipulating information. The use of hashtag in texts is an evidence of the societal changes in communication and represents the acceptance and diffusion of new contemporary social and discursive practices.

Marketingová strategie společnosti 3M v sociálních médiích / Marketing strategy of the company 3M in social media

Němec, Tomáš January 2016 (has links)
Diploma thesis focus on social media as a phenomenon of modern times and their use in a marketing. I will introduce four most frequently used social media - Facebook, Instagram, Twitter and YouTube as well as an outline the possibility of their use in marketing. Marketing strategy in social media I decided to introduce through a concrete example - an international company 3M. This company I chose mainly because it operates in the market of industrial products, where online marketing is not as much used and also because it cooperates with University of Economics. After introducing the basic marketing theories and explanations of basic terms I will analyze an existing 3M marketing strategy in social media and on the basis of the analysis and obtained data I will suggest my own possible marketing strategy for the company 3M, which connects all the aforementioned social media.

#MeToo: A case study of #sistabriefen

Andersson, Miranda January 2018 (has links)
As a result of the #MeToo movement in Sweden, #sistabriefen was created to represent the women, non-binaries and trans-persons working within the communications industry. This study analyzes the dynamics and identities of the #sistabriefen group members on their private social media platform. The analysis incorporates The Logic of Connective Action by Bennett and Segerberg (2012), and two complementary Social Identity Perspectives; Social Identity Theory and Self-Categorization Theory (Hogg & Terry, 2001; Hogg & Reid, 2006). The study consisted of 23 interview participants, and a qualitative content analysis over the course of five months. This research assesses how members are motivated to participate in the #sistabriefen group, how they identify themselves within the group, and how the group features affect members’ involvement. The findings of the research indicated that digital social movements have the potential to effectively mobilize social change.

TweetSense: Recommending Hashtags for Orphaned Tweets by Exploiting Social Signals in Twitter

January 2014 (has links)
abstract: Twitter is a micro-blogging platform where the users can be social, informational or both. In certain cases, users generate tweets that have no "hashtags" or "@mentions"; we call it an orphaned tweet. The user will be more interested to find more "context" of an orphaned tweet presumably to engage with his/her friend on that topic. Finding context for an Orphaned tweet manually is challenging because of larger social graph of a user , the enormous volume of tweets generated per second, topic diversity, and limited information from tweet length of 140 characters. To help the user to get the context of an orphaned tweet, this thesis aims at building a hashtag recommendation system called TweetSense, to suggest hashtags as a context or metadata for the orphaned tweets. This in turn would increase user's social engagement and impact Twitter to maintain its monthly active online users in its social network. In contrast to other existing systems, this hashtag recommendation system recommends personalized hashtags by exploiting the social signals of users in Twitter. The novelty with this system is that it emphasizes on selecting the suitable candidate set of hashtags from the related tweets of user's social graph (timeline).The system then rank them based on the combination of features scores computed from their tweet and user related features. It is evaluated based on its ability to predict suitable hashtags for a random sample of tweets whose existing hashtags are deliberately removed for evaluation. I present a detailed internal empirical evaluation of TweetSense, as well as an external evaluation in comparison with current state of the art method. / Dissertation/Thesis / Defense Presentation Slides / Masters Thesis Computer Science 2014

#instagramvsreality: Når kroppspositivismen fram till kvinnor genom den visuella kommunikationen?

Lindström, Hedda, Kääriä, Mélanie Chantal, Konradsson, Felicia January 2021 (has links)
Instagram är en social medieplattform som är populär i dagens samhälle. Det är en plattform som påverkar många människor på olika sätt. Ett sätt är att skildra en "ideal kroppsbild" eftersom instagramanvändare försöker skildra sig själva på bästa möjliga sätt. Detta resulterar i höga standarder som de flesta inte kan uppfylla. Som ett motstånd mot detta skapades hashtaggen "Instagramvsreality". Hashtaggen skapades för att visa verkligheten bakom några av Instagram-inläggen som ibland är redigerade eller inte visar hela bilden. I den här studien undersökte vi om meddelandet bakom Instagram-inlägget med hashtaggen Instagramvsreality och Instavsreality kom fram genom den visuella kommunikationen och hur det påverkade respondenterna. / Instagram is a social media platform that is becoming a big part of today's society. It is a platform that affects a lot of people in different ways. Research shows that one way is by portraying an “ideal body image” since Instagram users try to portray themself in the best manner possible. This results in high standards that most people cannot fulfill. As resistance to this, a body positivity movement came to life and with this the hashtag “Instagramvsreality”. The hashtag was created to show the reality behind some of the Instagram posts which are at times edited or do not show the whole picture. In this study, we investigated if the message behind the Instagram post with the hashtag Instagramvsreality and Instavsreality was understood through the visual communication and how it affected the respondents. The results show that most of the responders understand both the message with the message behind the Instagram posts and the bigger message behind the hashtag. While they are not affected by the hashtags encouraging message.

Bayasibulala: #AmINext? an analysis of Instagram as a tool for activism against Sexual Gender-Based Violence in South Africa

Mazana, Nandipha Nwabisa 24 March 2023 (has links) (PDF)
Research over the years has shown that there is a global rise in hashtag activism, this type of activism has also inspired what scholars call - hashtag feminism. Hashtag feminism utilizes Social Networking Sites to raise awareness about issues that are often not covered in traditional news media outlets such as TV, newspapers, and Radio Stations. Through this paper, I seek to investigate how Instagram has become one of the Social Networking Sites that has recently started being used for online activism in South Africa. This is done by conducting a qualitative analysis of 700 posts from the hashtag #AmINext, with a period focus of 3 months during South Africa's COVID-19 Level-5 Lockdown. The findings suggest that activists follow similar lines of the hashtag and social media activism parameters such as those of the #MeToo and #BeenRapedNeverReported movements. The analysis found that activists use Instagram to participate in Citizen Journalism by sharing information, raising awareness, organizing, mobilizing, and advocating (Vegh, 2003). Furthermore, there is clear Civic Engagement and Citizen Journalism through things such as sharing information and having calls to action while utilizing hashtags as a way to gain momentum and attention. The findings suggest that these hashtags are able to cultivate a community of activists all around the country while also making sure to encourage more participation. The analysis also shows how there is an importance of such activism when movement is restricted due to national Lockdowns implemented to curb COVID-19, as many victims of SGBV found themselves at home and trapped with their abusers. In paying attention to this analysis, I conclude that perhaps through the exploration of new ways of activism, we can ensure that no voice is ever left behind. Furthermore, despite the possibilities of these new ways of raising awareness and activism, it is always important to see how we can apply the old with the new.

A Hybrid Approach to Semantic Hashtag Clustering in Social Media

Javed, Ali 01 January 2016 (has links)
The uncontrolled usage of hashtags in social media makes them vary a lot in the quality of semantics and the frequency of usage. Such variations pose a challenge to the current approaches which capitalize on either the lexical semantics of a hashtag by using metadata or the contextual semantics of a hashtag by using the texts associated with a hashtag. This thesis presents a hybrid approach to clustering hashtags based on their semantics, designed in two phases. The first phase is a sense-level metadata-based semantic clustering algorithm that has the ability to differentiate among distinct senses of a hashtag as opposed to the hashtag word itself. The gold standard test demonstrates that sense-level clusters are significantly more accurate than word-level clusters. The second phase is a hybrid semantic clustering algorithm using a consensus clustering approach which finds the consensus between metadata-based sense-level semantic clusters and text-based semantic clusters. The gold standard test shows that the hybrid algorithm outperforms both the text-based algorithm and the metadata-based algorithm for a majority of ground truths tested and that it never underperforms both baseline algorithms. In addition, a larger-scale performance study, conducted with a focus on disagreements in cluster assignments between algorithms, shows that the hybrid algorithm makes the correct cluster assignment in a majority of disagreement cases.

El uso del inglés en la red social Facebook por jóvenes estudiantes de una universidad privada en Lima, Perú

Caldas Aquije, Xiomara Ximena, Mendoza Leo, Sara Yasmin, Rivera Gonzaga, Carla Maria 23 October 2018 (has links)
Desde el comienzo de nuestra era, las relaciones entre civilizaciones y culturas de diferentes partes del mundo presentaron diversos contactos lingüísticos entre los hablantes de distintos idiomas. Estos generaron una variación en el uso gramatical y, por ende, un nuevo vocabulario entre las lenguas contactadas, siendo el inglés, uno de los más destacados. Hoy en día, el inglés es el idioma con más influencia en el mundo y su uso en el Perú, sea mediante anglicismos o de forma general, es innegable. También es importante mencionar que la propagación del mismo es cada vez mayor gracias al apoyo de la tecnología y al uso de redes sociales. El presente trabajo busca observar el uso del inglés en la red social Facebook por jóvenes estudiantes de 18 a 25 años de una universidad privada de Lima Metropolitana. Este estudio propone ver de manera cualitativa qué tanto los jóvenes universitarios, de este sector en particular, utilizan el inglés en sus publicaciones. Dentro de los resultados se observó los siguientes tipos de uso: spanglish, memes y -en circunstancias generales- el hashtagging, entre otros factores que podrían complementarse con otros estudios, como el posible aprendizaje e integración del idioma inglés en esta u otras redes sociales y el uso de este idioma en otras ramas de investigación. / Since the beginning of our era, relations between civilizations and cultures from different parts of the world presented diverse linguistic contacts between speakers of different languages. These generated a variation in the grammatical use and, therefore, a new vocabulary among the contacted languages, being English one of the most outstanding ones. Nowadays, English is the most influential language in the world and its use in Peru, whether through anglicisms or in a general way, is undeniable. It is also important to mention that it is spreading and growing thanks to the support of technology and the use of social networks. The present work aims to observe the use of English in the social network of Facebook by young students from 18 to 25 years of a private university in Metropolitan Lima. This study proposes to see - with a qualitative scope - how young university students (in this particular sector) use English in their posts. The following types of use were observed in the results: Spanglish, memes and -in general circumstances- the hashtag; among other factors that could be complemented with other studies, such as the possible learning and integration of the English language in this or other social networks, and the use of this language in other branches of research. / Tesis

Twitter and Radio News: A Dallas-Fort Worth Case Study

Lambert, Mark T 08 1900 (has links)
This study of radio news stations adds to the field of Twitter research into broadcasters' use of this social media microblogging platform; previous research has predominantly focused on television. This case study, based on a survey with numerous open-ended questions completed in face-to-face interviews, begins to fill in data on how Twitter is being used in major market radio station newsrooms. Limited in scope, this exploratory study used answers from seven members of two radio newsrooms in trying to find out if there were stated goals for tweets; if separate, unique content was being tweeted or was content tied to the stations' on-air product; how tweets seek to increase station listenership and/or increase station website traffic; what were the most frequently tweeted topics; what hyperlinks were included in tweets for internal or external web content; and were tweets personal and/or opinionated, or kept more professional with just factual material. From a strategic management theory standpoint, there is neither a stated plan nor goals sought with these newsrooms' use of Twitter. Unique tweet content includes sending out photos which add visuals to the pictureless world of radio news and live-tweeting of ongoing news events, while complementary content is promotional to push audience members to on-air or website products. There are no analytics in place to try to determine whether the stations' listenership or web traffic increases based on tweets. Promotional teases of upcoming on-air guest interviews or news content and/or web content are the most frequently tweeted topics. Hashtags rather than hyperlinks are more often included in the stations' tweets. News personnel stay away from expressing opinions, or being too personal in tweets, but remain more objective and professional by sticking to facts which is in step with the traditional role of journalists.

Den tryckta annonsens förlängda arm : En studie i hur ett utvidgat kommunikationsutrymme skapas genom den tryckta annonsen / The extended arm of the printed ad : A study in how a room with extended communication is created through a printed advertisement

Andersson, Dennis, Magnusson, Lisa January 2012 (has links)
The foundation of our study is five strategically selected printed advertisements which all contains signs that refer to digital medias. Through a quality content analysis, we are studying how advertisers may use a room with extended communication too enlarge the space given in a printed advertisement. The potential in these rooms are proposing a social connection and a flexible interaction by providing content that is not possible to create in a printed advertisement. The form of communication is changing and there is a two-way communication created in an obvious way. The different kinds of roles in the communication process are here partially integrated with each other. The receiver and sender are included in a cyclic model where the message transfers in different directions. This kind of free form of communication may result in an effective diffusion of a positive message. It may also cause the sender to loose control of the message, which may lead to the initial purpose being lost or changed.
