While the Web has become a worldwide platform for communication, terrorists share their ideology and communicate with members on the "Dark Web"-the reverse side of the Web used by terrorists. Currently, the problems of information overload and difficulty to obtain a comprehensive picture of terrorist activities hinder effective and efficient analysis of terrorist information on the Web. To improve understanding of terrorist activities, we have developed a novel methodology for collecting and analyzing Dark Web information. The methodology incorporates information collection, analysis, and visualization techniques, and exploits various Web information sources. We applied it to collecting and analyzing information of 39 Jihad Web sites and developed visualization of their site contents, relationships, and activity levels. An expert evaluation showed that the methodology is very useful and promising, having a high potential to assist in investigation and understanding of terrorist activities by producing results that could potentially help guide both policymaking and intelligence research.

Focuses on business firms in Singapore, identifying the industries in which the Internet is being used for business. These firms are early adopters in the local environment where use of the Internet for business is a new phenomenon still, and they provide information about their Internet experience in terms of their use, perceptions, and the problems encountered. Finds that companies in seven major industries lead in the business use of the Internet in Singapore: computer and information technology; hospitality; manufacturing; travel; retail; publications; and banking and finance. Most of the survey respondents use the Internet for marketing and advertising, customer service and support, information gathering, and, to a lesser degree, electronic transactions. The respondents’ perception of the attributes of the Internet are largely positive. The problems encountered by the respondents include difficulty in locating information, rising costs of Internet use, and security.
