Social media is computer-based technology that facilitates the sharing of ideas, thoughts, and information through the building of virtual networks and communities. Twitter is one of the most popular social media in Indonesia which has 78 million users. Businesses rely heavily on Twitter for advertising. Businesses can use these types of tweet content as a means of advertising to Twitter users by Knowing the types of tweet content that are mostly retweeted by their followers . In this study, the application of Text Mining to perform clustering using the K-means clustering method with the best number of clusters obtained from the Silhouette Coefficient method on the @bliblidotcom Twitter tweet data to determine the types of tweet content that are mostly retweeted by @bliblidotcom followers. Tweets with the most retweets and favorites are discount offers and flash sales, so Blibli Indonesia could use this kind of tweet to conduct advertising on social media Twitter because the prize quiz tweets are liked by the @bliblidotcom Twitter account followers.

PIPELINES AND TIGHT RHYMES: VIRTUAL MEDIA AND HIP-HOP IN JAPAN & NEW ZEALAND

<p>This thesis looks at hip-hop as a contemporary pop cultural phenomena and its relationship with media in the construction of underground hip-hop communities in Japanese and New Zealand settings. My work on hip-hop in Japan illustrates how global networks influence a traditionally mono-cultural society reckoning with a style connected to African-American experience. A New Zealand setting illustrates how virtual networks allow connections to wider hip-hop culture from a geographically isolated setting and legitimises the local scene. In looking at both settings side-by-side, this thesis underscores the various ways that virtual networks and their increased visibility are used contemporaneously in the construction of local hip-hop scenes as a tool to understand and promote hip-hop music. Based on a mix of virtual fieldwork, fieldwork in New Zealand, as well as fieldwork in Japan, this thesis shows that questions of authenticity in hip-hop have become more complex through different manifestations of hip-hop culture that challenge traditional understandings of the genre’s meaning. This is a result of the varying levels of user-agency in virtual networks. In a Japanese setting, we see an increased importance placed on virtual networks, allowing hip-hop fans and musicians alike to be part of the immediate conversation. Language barriers to hip-hop’s dominant English vernacular mean that this conversation is generally filtered through the most dominant networks and ‘mainstream’ culture. These impressions of hip-hop are the driving forces of style for the Japanese scene, leading to a collapse of the dichotic underground/mainstream divide seen in the earlier generations of Japanese hip-hop. In a New Zealand setting, virtual networks are used to connect with English speaking hip-hop musicians overseas, allowing musicians to operate in ‘underground’ virtual communities that are not physically manifested in New Zealand. By drawing attention to the ways that hip-hop culture is formed, legitimized, and understood in these two geographic and cultural settings, this thesis demonstrates that hip-hop culture exists in an integral relationship with virtual media and explores questions of appropriation, imitation, and authenticity.</p>

Cognitive Control-Loop for Elastic Optical Networks with Space-Division Multiplexing

This paper introduces a new solution to improve network performance by decreasing spectrum fragmentation, crosstalk interference, blocking of virtual networks, cost, and link load imbalance. These problems degrade the performance of Elastic Optical Networks with Space-Division Multiplexing. The proposed solution, called Cognitive control loop (CO-OP), is capable of identifying a set of problems and creating plans to mitigate these problems. The CO-OP comprises four functions that employ learning algorithms to identify problems and plan a series of actions to reduce or eliminate them. The results show that the CO-OP can effectively decrease up to 30% the blocking of requests and up to 50% the crosstalk occurrence compared to existing algorithms.

Designing a conceptual framework for misinformation on social media: a qualitative study on COVID-19

Objective This study was aimed to present a conceptual framework about the misinformation surrounding COVID-19 outbreak in Iran. For this purpose, discourse analysis of two of the most common social virtual networks were conducted via a four step approach as follows: defining the research question and selecting the content of analysis, gathering information and theory on the context, content analysis for establishing the themes and patterns and, presenting the results and drawing conclusions. Results Cultural factors, demand pressure for information during the crisis, the easiness of information dissemination via social networks, marketing incentives and the poor legal supervision of online content are the main reasons for misinformation dissemination. Disease statistics; treatments and prevention are the main subjective categories of releasing misinformation. The consequences of misinformation dissemination include psychosocial, economic, health status, health system and ethical ones. The most recommended strategies for dealing with the issue could be divided into demand and supply-side strategies.

Fact-checking on Twitter: An analysis of the hashtag #StopBulos

The fact-checking is an important tool to improve the quality of the information that circulates in virtual networks. Although there are different fact-checking verification agencies, we also found some more informal strategies such as the use of the hashtag #Stopbulos. Thus, this research aims to characterize the #StopBulos hashtag on Twitter as a way to verify information and control the spread of fake news. The results showed that there was diversity among users and the themes of the tweets that included this hashtag, while the main function was to deny fake news. However, it was found that those who achieved greater dissemination were the users with the largest number of followers and institutional character. The implications of using the #StopBulos hashtag as a tool to identify false information on social networks are discussed. Keywords: fake news, post-truth, post-news, social media, network societies
