RIMS: A Real-time and Intelligent Monitoring System for live-broadcasting platforms

Personal live shows on Internet streaming platforms currently are blooming as one of the most popular applications on mobile phones and especially attracting millions of young generation users. The content supervision on live streaming platforms, in which there are thousands or hundreds of show rooms for performing and chatting synchronously, is a major concern with the development of this new service. Traditional image captures and real-time content analysis experience huge difficulties such as processing delay, data overwhelming, and matching overhead. In this paper, we propose a comprehensive method to monitor real-time live stream and to identify illegal or unchartered live misbehaviors intelligently based on various proposed aspects instead of image analysis only. The proposed system called RIMS makes use of several novel indicators on show room status rather than analyzing images solely to support real-time requirements. Three detecting techniques are adopted: self-adaptive threshold-based abnormal traffic detection, sensitive Danmaku comment perception, and frame difference analysis. RIMS can detect dramatically increasing of user number in a show room, filter sensitive words in Danmaku, and capture segmentation of video scenes by frame difference analysis. We deploy our system to monitor a typical live- broadcasting platform called panda.tv, and overall accuracy of detection via three indicators reaches 90.1%. The application of RIMS can change current supervison methods on live platforms that they totally rely on real-time manual review or after the event check. The key techniques in RIMS can also be widely employed in many other mobile applications in edge computing such as video surveillance in Internet of Things and mobile short video sharing

Information extraction

In this paper we present a new approach to extract relevant information by knowledge graphs from natural language text. We give a multiple level model based on knowledge graphs for describing template information, and investigate the concept of partial structural parsing. Moreover, we point out that expansion of concepts plays an important role in thinking, so we study the expansion of knowledge graphs to use context information for reasoning and merging of templates

PREDICTING PSYCHOLOGICAL RIPPLE EFFECTS OF CRISIS COMMUNICATION: INVESTIGATING THE JOINT EFFECTS OF MESSAGE AND MESSAGE RECEIVER ATTRIBUTES

In the event of an incidence of workplace violence, organizational post-crisis communication and media coverage of the incident typically provide details about the identity of the perpetrator and possible motivations for the act in an effort to facilitate the sense-making process for message receivers and to mitigate the organization's role in the crisis. In an increasingly globalized world, these messages are read by stakeholders of different nationalities with different cultural orientations. This dissertation examined the interacting influence of crisis message attributes such as the group membership (in-group, out-group) of the perpetrator, attributions of blame in the message (personal dispositional, situational) and message receiver attributes such as nationality (American, Indian) and cultural cognitive style (analytical, holistic) on psychological ripple effects in stakeholders and therefore on implications for an organization in crisis. Results indicated that Indian message receivers measured more holistic than American message receivers. Outcomes for an organization that had experienced a crisis depended on crisis type with the more negative implications being associated with the more preventable crisis according to stakeholders. Further, group membership of the perpetrator did not appear to affect organizational blame. However, contrary to predictions, it was the American message receivers who made a clearer distinction between in-group and out-group perpetrators and this evaluation was tied to the type of crisis. As hypothesized, holistic thinkers blamed the organization more when situational attributions were used in the crisis message; analytical thinkers blamed the organization more when personal dispositional attributions were used in the crisis message. Finally, the psychological ripple effects model showed that organizational blame decreased organizational trust, and increased anger in stakeholders. Angry stakeholders expressed a higher intention to engage in negative word-of-mouth and lowered purchase intention. Overall, the results point to a more complex phenomenon of crisis communication comprehension than is currently understood. Implications for theory and practice are discussed as well as directions for future research

The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research

The Hui Migrant Laborers’ Urban Experience and Implications for the Development of Civil Society in China

Recent unrest in China by migrant laborers’ increasing labor militancy, as well as unrest caused by Islamic groups in China ranging from separatist movements to backlash from discrimination have been the focus of the Chinese government’ attempts to main stability within the PRC. In the largest country in the world, rapid changes as the result of economic liberalization and the introduction of global capitalism have had drastic impacts on society, from increasing inequality to the introduction of Western media and ideas. Unrest has been accompanied by developments in civil society as Islamic institutions chafing under Chinese regulations become places of political discourse and migrant labors voice louder and louder demands independent and democratically elected trade unions. The Hui, the third largest ethnic minority in China and the largest Muslims minority have been involved in these recent civil society developments as both migrant workers and as an economically disadvantaged group. Their experience as a Muslim minority frequently subject to discrimination, an ethnic group with well-established Islamic institutions and community centers and their migrant worker identity all contribute to them having a unique role in the development of civil society in Chin

Understanding Varied Attitudes Towards Muslims

The focus of this research was to determine the prevalence and type of Islamophobia in the Victorian population. Islamophobia sentiment feeds the actions of right-wing extremist attacks on Muslim communities. But it has also become widespread in Australian society, and normalised in everyday settings, such as our mainstream media. Islamophobia cannot be treated with a singular approach or mode of intervention. Our study comes at a critical time; it provides empirical evidence on the extent of the problem, as well as documenting the varied manifestations of Islamophobic sentiment, with the view to developing potential action points and policy. In November 2019 we undertook a survey of 4019 Victorians. We asked questions on their attitudes towards cultural diversity, racial equality and privilege; trust and fairness; Muslims and Islam; and other ethno-cultural groups in Australian society; their experiences of racism and discrimination; their contact with Muslims and knowledge of Islam; and their political affiliation. To our knowledge, this was the largest survey undertaken in Victoria with the purpose of solely measuring Victorians perceptions of Muslims and Islam. Based on respondents’ answers, we used latent class analysis to segment the Victorian population. Five groups were generated: Islamophobic, Islamophobic with assimilationist tendencies, Undecided, Progressive with concerns about Islam, and Progressive. We then distilled the demographic and attitudinal attributes of these groups, with the view to identifying roles and drivers to help guide policy and intervention. We tested this five group segmentation with community organisations in Victoria working in the broad areas of diversity and multiculturalism, and with a particular emphasis on Muslim and non-Muslim relations. The groupings made sense on-the-ground, and they provided a strong pathway forward for program and policy design

The Chinese print media’s reporting of domestic ‘terrorist’ attacks: ideographs, social values and counter-terrorism frames

Following the attacks of September 11 2001 in the United States, China proclaimed its own ‘war on terror’ with the Uyghur of Xinjiang as a frontline. At the same time as ongoing US anti-terrorism efforts around the world, the Chinese government deployed repressive campaigns in one of its own troubled regions, campaigns which intensified with the riots in Urumqi in 2009. A series of high-casualty attacks since 2014 demonstrates further exacerbation of the conflict and entailed a strengthening of the counter-terrorism apparatus in the following years. Yet several scholars have questioned the nature of the purported terrorist threat to China, suggesting that the new narrative around the Uyghur issue was an attempt by the regime to preserve its authority and escape international condemnation for the severity of its actions. However, although these scholars highlight the party-state’s use of the terrorism label for the Xinjiang conflict, there is still a comprehensive analysis missing on how the party-state portrays the terrorist threat to its people. Responding to this research problem, this dissertation presents the first systematic analysis Chinese media coverage of domestic ‘terrorist’ attacks. Drawing upon eight cases from 2009 to 2015, and twelve Chinese newspapers, this analysis focuses on the determinants of terrorism coverage and framing patterns through a combination of qualitative content analysis and quantitative text analysis. I argue that the Chinese party-state engages through various methods of news censorship and coordination to construct a terrorist threat that is surprisingly abstract- invoking extremism as the threat, but without referring much to particular agents, organisation or religions. Also, I argue that the party-state uses the abstract terrorism portrayal to campaign against all ‘three evil forces’ (terrorism, extremism, separatism), while also promoting social values that align with the regime’s resilience. The dissertation reveals the various frames that make up the party-state’s terrorist threat construction. It demonstrates that the party-state uses the Xinjiang conflict to rally the Chinese people under the flag of the Chinese Communist Party while also creating the image of an archetypical enemy that can be applied to a large range of party-state perceived threats. These features of the Chinese news coverage of ‘terrorist’ attacks shed light on the mediated reality of the conflict and provide an alternative perspective to US-centred media scholarship on terrorism

Design of a Controlled Language for Critical Infrastructures Protection

We describe a project for the construction of controlled language for critical infrastructures protection (CIP). This project originates from the need to coordinate and categorize the communications on CIP at the European level. These communications can be physically represented by official documents, reports on incidents, informal communications and plain e-mail. We explore the application of traditional library science tools for the construction of controlled languages in order to achieve our goal. Our starting point is an analogous work done during the sixties in the field of nuclear science known as the Euratom Thesaurus.JRC.G.6-Security technology assessmen
