The precious data from online origin has developed into a extended research. The mass media and news media provides the daily events to the common people. Huge amount of information is been achieved by an online social media suchlike Twitter, which contains more information about news-associated content. It is necessary to find a way to filter noise, for these resources to be useful and grab the content that is depend on the similarity to news media. Despite after the noise is eliminated the excessive data still remain in the data so it is essential to prioritize it for utilization. We are introducing three factors for prioritization. The unsupervised technique finds the news topics that are common in the pair of social media and news media, and then ranks them by the applicability factors such as MF, UA and UI. Initially the temporal prevalence of the appropriate topic in news media focus (MF). Secondary the temporal prevalence of the appropriate topic in social media illustrates the user attention (UA). Finally the interconnection among the social media users who specify this topic demonstrates the power of the society who is discussing; it is termed as the user interaction (UI).

In early days, mass media sources such as news media used to inform us about daily events. Now a days, social media services such as Twitter huge amount of user-generated data, which has a great potential to contain informative news-related content. For these resources to be useful, we have to find a way to filter noise and capture the content that, based on its similarity to the news media, is considered valuable. Even after noise is removed, information overload may still exist in the remaining data. Hence it is convenient to prioritize it for consumption. To achieve prioritization, information must be ranked in order of estimated importance considering mainly three factors. First, the temporal prevalence of a particular topic in the news media is a factor of importance, and can be considered the media focus (MF) of a topic. Second, the temporal prevalence of the topic in social media indicates its user attention (UA). Last, the interaction between the social media users who mention this topic indicates the strength of the community discussing it, and can be regarded as the user interaction (UI) toward the topic. We propose an unsupervised framework—BlogNewsRank—which identifies news topics prevalent in both social media and the news media, and then ranks them by relevance(frequency) using their degrees of MF, UA, and UI.

Today’s consumers are too smart to buy their needs through various means. But before buying their needs, they go through various online sites and social media review about product performances and price. While surfing this information they can able to evaluate its real value and price advantages, since online establishment need not spend cost for showroom with staff. Consumers need not roam here and there to various shops to evaluate the product performance and its cost. Moving from one place to other is tedious journey and time-consuming part. It is also difficult to ensure their required models are available or not. Moreover, consumers can view forthcoming new models in the manufacture’s site whereas these details may not be shared in showrooms. Earlier accessing internet is complicated and needs a system to view. Now this can be accessed through smart phone. The prices of smart phone were also drastically lowered. After the entry of Jio network, the cost of one GB data were brought down to Rs 15/to Rs 20/- from Rs 250/-. This could be an affordable price for the common people. With the above improvements, the smart phone usage in the country has increased and every smart phone user are in a habit of surfing the internet or interacting in the social media now and then. While so, everybody can be able to see the various products in the online markets and its review. This will provoke the user to buy the products through online. In America ToySaras and BabySaras, retail showrooms of baby products were forced to close during 2018, since most of Americans preferred to shop through online and few other retail shops are in the same stage of closing. The above situation may also be aroused to Indian Market in the near future. To know the objective of the consumers’ preference and their choice, customers’ voice obtained through survey may be helped to us and its findings may help the online marketers to fine tune their strategies accordingly.

Merchants in the Tokugawa period were placed at the bottom of the shinōkōshō hierarchy of samurai-peasants-artisans-merchants. This social hierarchy was produced by a combination of social reality at the time Japan was unified in the late sixteenth century and an ancient Chinese physiocratic theory, never taken very seriously, in practical ways, in China. Once the country was unified, the social mobility of the previous years, of a kind which permitted men of ability to climb from the lowest ranks to join the military nobility—Hideyoshi is the prime example of this mobility—was viewed, by Hideyoshi above all others, as a cause of prolonged chaos and internecine warfare. With the argument that war had been abolished and common people therefore no longer needed weapons, Hideyoshi carried out his ‘sword-hunt’. He thus established the most fundamental of the class distinctions, between the samurai, the ruling class, who now enjoyed a monopoly of bearing arms, and the common people, who were henceforth expected simply to produce the food and other necessities of life, and to pay their taxes, which remained high even though warfare was supposedly ended.

The incorporation of digital sources from online social media into historical research brings great opportunities, although it is not without technological challenges. The huge amount of information that can be obtained from these platforms obliges us to resort to the use of quantitative methodologies in which algorithms have special relevance, especially regarding network analysis and data mining. The Recovery of Historical Memory in Spain on the social network Twitter will be analysed in this article. An open-code tool called T-Hoarder was used; it is based on objectivity, transparency and knowledge-sharing. It has been in use since 2012.

On May 2, 2011, Canadians voted in what the news media dubbed “Canada's First Social Media Election.” This allowed Canadians to join their neighbours to the south who, arguably, had gone through one national social media election during the 2008 bid for the presidency. Through a theoretical discussion of what constitutes sociality and networked sociality, and a critical examination of social media as a campaign tool, this chapter asks “What makes a campaign social?” It also asks if the term “social media campaign” adequately describes current campaign practices? In exploring these questions, the chapter draws on the 2011 federal election in Canada and the 2008 American election. Ultimately, the chapter argues we have limited evidence that social media has led to increased sociality when it comes to electoral politics. This calls the appropriateness of the term “social media campaign” into question. Such lack of evidence stems from the dynamism of networked sociality, which renders it difficult to understand, and methodological difficulties when it comes to capturing what it means to be “social.”

This chapter discusses the life and work of Daniel Friberg, who takes a leading part in running a range of online media. Friberg’s main impact has been his implementation of metapolitics. Distinguished by his strategy and method rather than ideological inventions, Friberg advanced his career through a series of outreach, rebranding, and socialization initiatives. The products of this metapolitical activism include multiple newspapers and magazines, a publishing house, and online social media. By the 2010s these projects were replacing skinheadism as the social center of a fractious and sectarian Nordic radical nationalism. This unifying function has since been at the forefront of collaboration between American and European white activists.

This chapter studies the role that Hasidism played in the thought of the modernized Jewish intelligentsia of Eastern Europe toward the end of the 19th century. Simon Dubnow played a pivotal role in the emergence of this new image of Hasidism. In his autobiography, Dubnow describes in some detail the influence on him at that time of Leo Tolstoy and Ernest Renan. The influence of Renan's History of Christianity is quite evident in the structure of Dubnow's History of Hasidism as well as in some of Dubnow's solutions to problems of interpretation. Like Renan, Dubnow opened with a discussion of the social and intellectual background of a movement that can be traced to a founder known only for a long time through oral sources which retained the character of legend or saga. Applying Renan's statement that such pious biographies have a historical core, Dubnow stripped the life of the Baal Shem Tov, as recorded in the Shivhei ha-Besht, of its supernatural elements to reveal a simple, humble man who loved nature, especially the forests of the Carpathian mountains; a man who had immense affection for the common people and disdain for the proud, aloof scholars of his time and who preached a lofty doctrine of religious pantheism and universal brotherhood.

The emergence of social media over the last decade has substantially altered not only the means people communicate with each other but also the whole online ecosystems. For the common public in particular, social media enables and broadens the social conversation that anyone interested can engage in on urgent social problems such as environmental pollution. In China, the ever-thickening air pollution smothering most urban cities in recent years has provoked a nationwide discussion, and popular social media like Weibo has been fully utilised by various social actors to participate in this “green speak”. This paper examines the civil discourse about the deteriorating air pollution on China’s largest microblogging platform-Sina Weibo, and seeks to understand how different social actors respond to and reconstruct the reality. Through a discourse analysis aided by a text analytics/ visualisation software—eximancer, this paper investigates the civil discourse from three angles: the demographics, the discursive strategies and the potential social effect. The result suggests that proactive civil engagement in this issue has produced an environmental discourse with a wide range of topics involved, and that the benign interactions between social actors could give rise to a proactive interactional mode between Chinese state and civil society which would definitely be beneficial to the democratisation process in contemporary China.

Social media has transformed public discourse on policing and the contest of control over the police image. This article draws on original, empirical research to conceptualise the phenomenon of the ‘social media test’ – the evolution of social media into a legitimate measure of police performance. Through in-depth interviews with police and non-police respondents the article maps the genealogy of, and provides perspective on, one of the first viral cases of bystander video of police excessive force in Australia filmed and uploaded to YouTube. The study shows the video’s impact on hegemonic mainstream and police news media narratives, processes of criminalisation and police accountability and the merit of narrative criminology in unpacking these phenomena. Police alluding to the ‘social media test’ in in-depth interviews shows that digital media in general and social media in particular can no longer be dismissed as peripheral or subsidiary to public discourse on policing in a digital society.
