Measuring Blog Influence: Recognition, Activity Generation, and Novelty

Netizens around the world increasingly use blogs to share thoughts and opinions, create special interest groups, collaborate, and debate on issues. However, the social influence of blogs remains largely undetermined. This paper presents the outcomes of a study which investigates how the influence of blogs can be measured quantitatively. The purpose of the study was to determine how to assess the social influence of blogs and to develop two new tools for measuring blog influence: the Blog Influence Index BII and Blog Influence Analyzer BIA. These tools were applied to identify top influential blogs in the blogosphere community of Malaysia. The results indicate that the top 10 most influential blogs in Malaysia fall under the categories of politics, entertainment, sports, lifestyle, and technology.

Blog Influence Index: A Measure of Influential Weblog

Although weblogs are a popular medium of communication, their influence on society is unclear. In particular, studies that investigate the impact and influence of blogosphere on the community and government have not been fully exploited. Such studies are important especially to the government in reshaping and realigning the policies related to new media. This article presents the outcomes of a study to identify measures on how to assess the influence of weblogs. At least four dimensions are critical for measuring weblog influence, which are recognition (number of in links and number of visitors), activity generation (number of comments and number of posts), novelty (number of out links), and credibility of a blog (number of information presentation type, number of factual errors, and number of hyperlink citations). It is hereby proposed that these dimensions make up a measure called the Blog Influence Index.

From grids to clouds: Recap on challenges and solutions

Grid Computing is a set of resources; the separate computational power of these resources has combination to execute a huge task. Usually, in a Computational Grid environment, the main resource is the Central Processing Unit (CPU), mostly used in research fields that demand high computational power to perform massive and complicated calculations. Cloud Computing is a promising computing pattern which offers facilities and common resources on demand over the Web. The implementation of cloud computing applications has high priority, especially in the modern world, for example in providing adequate funding for social services and purchasing programs. In this paper, we discuss the implementation of cloud computing over a Smart Grid: reliable, guaranteed and efficient with low cost, it is expected to offer Long Term Evolution (LTE). This allows larger pieces of the spectrum, or bands, to be used, with greater coverage and less latency. The third technology is the Vehicular Network, an important research area because of its unique features and potential applications. In this survey, we present an overview of the smart grid, LTE and vehicular network integrated with cloud computing. We also highlight the open issues and research directions in implementing these technologies with cloud computing in terms of energy and information management for smart grids; applying cloud computing platforms for 4G networks to achieve specific criteria; and finally architectural formation, privacy and security for vehicular cloud computing.

An analysis of Wi-Fi security vulnerabilities in Malaysia: A survey in Golden Triangle Kuala Lumpur

The widespread use of Wi-Fi in the US and Europe has brought a new security concern among Wi-Fi owners and developers. However this concern and awareness are still low in Malaysia. A survey using the NetStumbler and a GPS receiver to locate the coordinates of detected Wi-Fi APs was carried out in the Golden Triangle area of Kuala Lumpur, Malaysia. This paper will describe how far the owners and administrators in Malaysia secure their Wi-Fi networks and subsequently create security awareness among Wi-Fi owners and administrators.
