Blogs and social networks have recently become a valuable resource for mining sentiments in fields as diverse as customer relationship management, public opinion tracking and text filtering. In fact knowledge obtained from social networks such as Twitter and Facebook has been shown to be extremely valuable to marketing research companies, public opinion organizations and other text mining entities. However, Web texts have been classified as noisy as they represent considerable problems both at the lexical and the syntactic levels. In this research we used a random sample of 3516 tweets to evaluate consumers' sentiment towards well-known brands such as Nokia, T-Mobile, IBM, KLM and DHL. We used an expert-predefined lexicon including around 6800 seed adjectives with known orientation to conduct the analysis. Our results indicate a generally positive consumer sentiment towards several famous brands. By using both a qualitative and quantitative methodology to analyze brands' tweets, this study adds breadth and depth to the debate over attitudes towards cosmopolitan brands.

More than words: Social networks' text mining for consumer brand sentiments

Review of The people's choice: How the voter makes up his mind in a presidential campaign.

This study explored how the structure of globalization of technology via intellectual propertynetworks has changed longitudinally, and compares the structures of global trademarks andpatents. It suggests that network analysis provides useful tools for describing recent trends inthe globalization of technology. Network analyses describe which countries have highertechnological capabilities, and also how countries are mutually connected for technologicalcollaboration or transfer. In addition, network analysis confirmed that both the trademark andpatent networks have become decentralized over time.© 2011 Elsevier Inc. All rights reserved.

Technological Forecasting & Social Change

The African continent is distinguished by a much higher fertility rate than other regions. Fertility in Africa has remained almost constant at slightly over six children per woman on average while important declines have occurred elsewhere over the past 25 years. High fertility in Africa is often attributed to poor diffusion of family planning early marriage and low female educational attainment but other cultural and economic factors are involved. The significant decline of infant mortality over the past several decades has produced growth rates never before observed. Africas very young populations may be at the origin of uncontrollable political disorder as young persons with bleak prospects fall easy prey to ethnic religious and political extremism. Demographic growth has become an additional barrier to development. High fertility is tolerated or encouraged as constituting a cultural trait but the resulting population growth is not a cultural trait. Demographic pressure has increased environmental problems in many regions. It is estimated that over ten million rural residents of the Sahel have been affected by soil degradation. The per capita availability of arable land fell from one-half to one-third hectare between 1965 and 1987. Shortages of firewood and water have become more common. The relationship between demographic growth environmental crisis and poverty in the countryside depends on other factors such as production techniques modes of access to land and water and the degree of security of land tenure. Population pressure was not the initial factor that disturbed the balance of the traditional societies but it exacerbated the effects of other forces such as the introduction of cash crops and monetarization of the economy. Rural exodus and accelerated urban migration have been prompted in large part by the higher incomes and greater availability of services of all types in the cities. Achieving control of fertility in Africa will require stabilization of rural populations territorial management and reduction of disparities between rural and urban areas.

An end to poverty

1. Apply the communication theory in order to: analyze their own social environments public opinion and mass culture phenomena; understand and explain the reality in where they live; value the theoretical approach on communication. 2. Elementally determine mass communication methods and research techniques, practice them, and derive their social implications. 3. Differentiate and relate multiple perspectives on mass communication theory, from the traditional approaches to the ones emerged in the network society. 4. Estimate the market as a core player in the development and expansion of mass communication and culture. 5. Achieve a critical analysis of the social, political and cultural implications of the communication modalities emerged in the information society.

Comparing Twitter and YouTube networks in information diffusion: The case of the “Occupy Wall Street” movement

Cyworld, a Korean social networking site (SNS), enables politicians to establish and maintain their online presence and allows them to communicate with constituents through their personal profile. This article identifies the most visible politicians on Cyworld in terms of comments posted on their profiles between April 1, 2008 and June 14, 2009 and examines the text and sentiments reflected in those profiles. A content analysis combining semantic network analysis and sentiment analysis illustrates the meaning and collective sentiment of the comments. The results suggest that progressivism dominated political discourse and that the members of the ruling party received more negative comments than those of the opposition party. Furthermore, group-oriented terms indicated the existence of collectivism, which is representative of Eastern culture. The results suggest a significant relationship among gender, comment types, and SNS activities.

Networked Politics on Cyworld: The Text and Sentiment of Korean Political Profiles

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 demograp...

Information networks and social media use in public diplomacy: a comparative analysis of South Korea and Japan

Using network analysis, this study examines the current structure of international music trade flow and its determinants. International music trade data from the United Nations Commodity Trade Statistics database are employed to describe the international music flow network and how it changed between 2002 and 2006. Network analysis reveals the imbalance of international music trade between the core and the periphery. Specifically, the USA and European countries including Germany, the UK and the Netherlands are at the core, dominating international trade of music products. Over the five-year period, the international music trade network remained relatively stable. Regression analysis indicates that a country’s economic development, the language(s) its people speak and technological development are influential factors that determine the global structure of international music flows.
