Top1. Introduction
Social media has emerged as a paradigm shift in generating and sharing information that can influence personal mentalities and thoughts (Nasukawa & Yi 2003). In fact, social media websites can be used to disseminate hate, war, racism, and other evil acts by anti-social elements that influence users with evil thoughts, which is considered a big threat to security (Schmid 2013). The speed of disseminating thoughts among people is facilitated by the flexibility and social interactions found in social media websites (Choi & Park 2014). These features might help in shaping (framing) pubic opinions. Lotan et al.(2011) claims that,
Mainstream Media (MSM) outlets have adopted Twitter as a means of engaging with and enlarging audiences, strengthening their reach and influence while also changing how they rely on and republish sources.
The concept of framing in the communication paradigm refers to “the process by which a communication source, such as a news organization, defines and constructs a political issue or public controversy” (Nelson et al. 1997). The concept is considered one of the most fertile research areas in mass communication (Matthes 2009). It involves the use of theory when judging content. It also applies many methods in frame analysis, whether using quantitative or qualitative analysis (Matthes 2009). Media framing is well-known in political issues and public controversy, in an experiment by Nelson et al. (1997) to measure the media power in shaping public views and political problems, they found that media framing provided strong drivers for political judgment and opinion.
With the emergence of social media websites such as Facebook and Twitter, the speed and magnitude of spreading news that reach a large segment of people has increased. Twitter, for instance, is a widely used micro-blogging website. It has gained great popularity in the era of social media. It has a total number of users exceeding one billion (Smith 2014), 0.8% are from the Arab region (ASMR 2013). Twitter has extensively been used in the Arab region as a mass communication media. On “Dubai School of Government” March report about social media usage in the Arab region, it states that there were 3.7+ million Twitter active users in the Arab world with 1.9 million users from Saudi Arabia alone (ASMR 2013). This boom in Twitter usage, especially in Saudi Arabia, is attributed to many factors such as the use of Arabic hash tags, the low cost of 3G enabled mobile phones and the emergence of Arab spring (Huang 2011). Actually, social media has been instrumental in mass street demonstrations in Arab spring, such as those in Tunisia, and Egypt (Huang 2011), were they used social media, such as Twitter, to organize protests or spread awareness about them (Lotan et al. 2011). In short, Twitter has played an important role in facilitating revolutions in the Arab region. It was used primarily to disseminate news and recently was employed to silence political protests (Thomas et al. 2013).
Today, spam and spammer are well-known phenomena in social media websites, according to a recent report by Nexgate.com, during the first half of 2013 there was a 355% growth in social spam (H. Nguyen 2013). Such growth has pushed researchers to conduct research and develop systems to identify and analyze Twitter spam accounts.
