De blogs entre los blogs

Este artículo hace parte de la revista Papel de colgadura de la Facultad de Derecho y Ciencias Sociales de la Universidad Icesi de Cali, es una publicación de difusión y agitación cultural. La revista nace de la pasión por la música, los libros, las ilustraciones, el graffiti, los cómics, la web, la fiesta, el cine, la cafeína y de las tardes de tertulia con empanadas y cerveza, que circula en versión impresa dos veces al año, pero su versión digital se actualiza con mayor frecuencia.

Clasificador semántico de medios sociales mediante análisis basado en expresiones: aplicación a blogs y diarios

La reputación corporativa es la percepción que los diferentes públicos de una empresa tienen acerca de la misma. Estos públicos o stakeholders, son aquellos que se relacionan con la empresa de cualquier manera, pudiéndose distinguir entre públicos internos, empleados, accionistas, directivos, …; y públicos externos, clientes, proveedores, fondos de inversión, …. En los últimos años estamos presenciando como las empresas e instituciones dedican importantes esfuerzos a desarrollar políticas de Reputación Corporativa, ya que una disminución de la reputación redunda directamente en la cuenta de resultados de las compañías por lo que las mejoras que se introduzcan en la gestión de la reputación redundaran directamente en su sostenibilidad económica y social del país donde operan.Para poder medir la RC de una empresa o institución es preciso determinar el sentimiento que dicha empresa o institución tiene en sus públicos. Pero llevar a cabo esta medición es cada día más difícil, ya que la sociedad de la información donde estamos inmersos, hace que los canales de comunicación de los públicos sean mucho mayores que hace unos años( redes sociales, blog, diarios, foros, …) y además, la comunicación puede hacerse casi en tiempo real, tal como sucede en las redes sociales. Para hacer estas mediciones, las principales empresas del sector han utilizado principalmente encuestas las cuales las realizaban empresas especializadas, lo que supone un alto coste y además, los resultados son obtenidos a tiempo pasado o no se alcanza un tamaño de población significativa.El objetivo de este trabajo es realizar una aplicación para determinar la reputación de una empresa en medios de comunicación online. Para ello, se ha desarrollado un sistema de lectura de medios online, que permite localizar y extraer la información de los medios de comunicación online; un clasificador semántico para analizar la información recogida y clasificarla en diferentes temáticas extrayendo el sentimiento de los textos; y finalmente, una interfaz para interactuar con el usuario.

Efeitos dos vídeo-blogs na decisão de compra de produtos cosméticos

Este estudo enquadra-se na área do Marketing Digital, e pretende demonstrar a influência exercida pelos vídeo-blogs no YouTube na decisão de compra de produtos cosméticos em Portugal. Aborda inicialmente conceitos como as redes sociais, mais concretamente os vídeoblogs e a rede social YouTube, o comportamento do consumidor online, o mercado da cosmética em Portugal e o Marketing ligado à industria da beleza. O objetivo deste estudo é o de demonstrar como as marcas de cosmética podem aumentar as suas vendas e notoriedade com a influência exercida pelas beauty vloggers. A fim de perceber a influência na tomada de decisão no que diz respeito a produtos de cosmética, adotámos uma metodologia quantitativa, que assentou na realização de inquéritos online por questionário. Os dados foram organizados e analisados com a ajuda do software de análise quantitativa SPSS. Os principais resultados observados determinam uma influência positiva dos vídeo-blogs na decisão de compra de produtos cosméticos. Esta influência poderá demonstrar que o sucesso das empresas de cosméticos na divulgação, venda e fidelização de clientes deve apontar cada vez mais para a utilização intensiva de video bloggers dedicadas a temas de beleza, e identificadas no estudo como líderes de opinião, para as suas estratégias de comunicação.

Monitoring the Australian Blogosphere through the 2007 Australian Federal Election

This paper examines the observable patterns of content creation by Australian political bloggers dur‐ing the 2007 election and its aftermath, thereby providing insight into the level and nature of activity in the Australian political blogosphere during that time. The performance indicators which are identi‐fied through this process enable us to target for further in‐depth research, to be reported in subse‐quent papers, those individual blogs and blog clusters showing especially high or unusual activity as compared to the overall baseline. This research forms the first stage in a larger project to investigate the shape and internal dynamics of the Australian political blogosphere. In this first stage, we tracked the activities of some 230 political blogs and related Websites in Australia from 2 November 2007 (the final month of the federal election campaign, with the election itself taking place on 24 Novem‐ber) to 24 January 2008. We harvested more than 65,000 articles for this study.

Mapping the Australian political blogosphere

Network crawling and visualisation tools and other datamining systems are now advanced enough to provide significant new impulses to the study of cultural activity on the Web. A growing range of studies focus on communicative processes in the blogosphere – including for example Adamic & Glance’s 2005 map of political allegiances during the 2004 U.S. presidential election and Kelly & Etling’s 2008 study of blogging practices in Iran. There remain a number of significant shortcomings in the application of such tools and methodologies to the study of blogging; these relate both to how the content of blogs is analysed, and to how the network maps resulting from such studies are understood. Our project highlights and addresses such shortcomings.

A constructivist approach to media literacy education: The role of the library

An informed citizenry is essential to the effective functioning of democracy. In most modern liberal democracies, citizens have traditionally looked to the media as the primary source of information about socio-political matters. In our increasingly mediated world, it is critical that audiences be able to effectively and accurately use the media to meet their information needs. Media literacy, the ability to access, understand, evaluate and create media content is therefore a vital skill for a healthy democracy. The past three decades have seen the rapid expansion of the information environment, particularly through Internet technologies. It is obvious that media usage patterns have changed dramatically as a result. Blogs and websites are now popular sources of news and information, and are for some sections of the population likely to be the first, and possibly only, information source accessed when information is required. What are the implications for media literacy in such a diverse and changing information environment? The Alexandria Manifesto stresses the link between libraries, a well informed citizenry and effective governance, so how do these changes impact on libraries? This paper considers the role libraries can play in developing media literate communities, and explores the ways in which traditional media literacy training may be expanded to better equip citizens for new media technologies. Drawing on original empirical research, this paper highlights a key shortcoming of existing media literacy approaches: that of overlooking the importance of needs identification as an initial step in media selection. Self-awareness of one’s actual information need is not automatic, as can be witnessed daily at reference desks in libraries the world over. Citizens very often do not know what it is that they need when it comes to information. Without this knowledge, selecting the most appropriate information source from the vast range available becomes an uncertain, possibly even random, enterprise. Incorporating reference interview-type training into media literacy education, whereby the individual will develop the skills to interrogate themselves regarding their underlying information needs, will enhance media literacy approaches. This increased focus on the needs of the individual will also push media literacy education into a more constructivist methodology. The paper also stresses the importance of media literacy training for adults. Media literacy education received in school or even university cannot be expected to retain its relevance over time in our rapidly evolving information environment. Further, constructivist teaching approaches highlight the importance of context to the learning process, thus it may be more effective to offer media literacy education relating to news media use to adults, whilst school-based approaches focus on types of media more relevant to young people, such as entertainment media. Librarians are ideally placed to offer such community-based media literacy education for adults. They already understand, through their training and practice of the reference interview, how to identify underlying information needs. Further, libraries are placed within community contexts, where the everyday practice of media literacy occurs. The Alexandria Manifesto stresses the link between libraries, a well informed citizenry and effective governance. It is clear that libraries have a role to play in fostering media literacy within their communities.

Trends in online journalism : a case study approach based on euaustralia online

This paper takes stock of current changes affecting journalism, and as a case study brings up to date the record of progress made with an online publishing enterprise, EUAustralia Online, first reported on in 2007. It perceives the development of news publishing on line as being in two sectors: media corporations moving to occupy the online publishing field, through complex business stratagems and product-making, and small publications enjoying low production costs and the ability to strike up relationships with numerous users, even on a mass scale. Recent developments in both major publishing and niche publishing are appraised in a literature review, considering both broad-scale industry trends; and pressure from fresh advances in information and communication technology to produce ever-more sophisticated media artefacts, like multi-platform news coverage. The paper also recounts the pattern of work on EUAustralia Online, showing how such publications, ubiquitous ‘blogs’ or newsletters, may be placed in a prospective online order, where large and small operations might co-exist.

State-of-the-Art Review on Opinion Mining from Online Customers’ Feedback

Dealing with the ever-growing information overload in the Internet, Recommender Systems are widely used online to suggest potential customers item they may like or find useful. Collaborative Filtering is the most popular techniques for Recommender Systems which collects opinions from customers in the form of ratings on items, services or service providers. In addition to the customer rating about a service provider, there is also a good number of online customer feedback information available over the Internet as customer reviews, comments, newsgroups post, discussion forums or blogs which is collectively called user generated contents. This information can be used to generate the public reputation of the service providers’. To do this, data mining techniques, specially recently emerged opinion mining could be a useful tool. In this paper we present a state of the art review of Opinion Mining from online customer feedback. We critically evaluate the existing work and expose cutting edge area of interest in opinion mining. We also classify the approaches taken by different researchers into several categories and sub-categories. Each of those steps is analyzed with their strength and limitations in this paper.

Blog and design education : facilitating reflective learning

This paper discusses about effectiveness of blogs for reflective learning in design education. Students in two animation units were asked to complete their online journal via blog in terms of reflective learning. Students were encouraged to respond their weekly outcomes and project development process to their blog and share it with other students. A survey was undertaken to evaluate their learning experience and one of the key outcomes indicates that interaction design for social network is significantly important to blog based learning design.

Which way up? Reading and drawing maps of the blogosphere

Mapping the physical world, the arrangement of continents and oceans, cities and villages, mountains and deserts, while not without its own contentious aspects, can at least draw upon centuries of previous work in cartography and discovery. To map virtual spaces is another challenge altogether. Are cartographic conventions applicable to depictions of the blogosphere, or the internet in general? Is a more mathematical approach required to even start to make sense of the shape of the blogosphere, to understand the network created by and between blogs? With my research comparing information flows in the Australian and French political blogs, visualising the data obtained is important as it can demonstrate the spread of ideas and topics across blogs. However, how best to depict the flows, links, and the spaces between is still unclear. Is network theory and systems of hubs and nodes more relevant than mass communication theories to the research at hand, influencing the nature of any map produced? Is it even a good idea to try and apply boundaries like ‘Australian’ and ‘French’ to parts of a map that does not reflect international borders or the Mercator projection? While drawing upon some of my work-in-progress, this paper will also evaluate previous maps of the blogosphere and approaches to depicting networks of blogs. As such, the paper will provide a greater awareness of the tools available and the strengths and limitations of mapping methodologies, helping to shape the direction of my research in a field still very much under development.

Recommending best answer in a collaborative question answering system

The World Wide Web has become a medium for people to share information. People use Web-based collaborative tools such as question answering (QA) portals, blogs/forums, email and instant messaging to acquire information and to form online-based communities. In an online QA portal, a user asks a question and other users can provide answers based on their knowledge, with the question usually being answered by many users. It can become overwhelming and/or time/resource consuming for a user to read all of the answers provided for a given question. Thus, there exists a need for a mechanism to rank the provided answers so users can focus on only reading good quality answers. The majority of online QA systems use user feedback to rank users’ answers and the user who asked the question can decide on the best answer. Other users who didn’t participate in answering the question can also vote to determine the best answer. However, ranking the best answer via this collaborative method is time consuming and requires an ongoing continuous involvement of users to provide the needed feedback. The objective of this research is to discover a way to recommend the best answer as part of a ranked list of answers for a posted question automatically, without the need for user feedback. The proposed approach combines both a non-content-based reputation method and a content-based method to solve the problem of recommending the best answer to the user who posted the question. The non-content method assigns a score to each user which reflects the users’ reputation level in using the QA portal system. Each user is assigned two types of non-content-based reputations cores: a local reputation score and a global reputation score. The local reputation score plays an important role in deciding the reputation level of a user for the category in which the question is asked. The global reputation score indicates the prestige of a user across all of the categories in the QA system. Due to the possibility of user cheating, such as awarding the best answer to a friend regardless of the answer quality, a content-based method for determining the quality of a given answer is proposed, alongside the non-content-based reputation method. Answers for a question from different users are compared with an ideal (or expert) answer using traditional Information Retrieval and Natural Language Processing techniques. Each answer provided for a question is assigned a content score according to how well it matched the ideal answer. To evaluate the performance of the proposed methods, each recommended best answer is compared with the best answer determined by one of the most popular link analysis methods, Hyperlink-Induced Topic Search (HITS). The proposed methods are able to yield high accuracy, as shown by correlation scores: Kendall correlation and Spearman correlation. The reputation method outperforms the HITS method in terms of recommending the best answer. The inclusion of the reputation score with the content score improves the overall performance, which is measured through the use of Top-n match scores.
