Abstract:


Due to easy accessibility and availability of Internet, non-social elements are continuously utilizing it as a cost-effective infrastructure for disseminating information across the globe. Consequently, it is becoming a challenging task for intelligence agencies to track movement and activities of suspects around the globe. Since tracking of a single suspect can generate a large amount of semantic data, important details can be lost in a large volume of text resulting into an information overload problem. Moreover, due to huge size and dynamic nature of the WWW, a constant manual monitoring is not a feasible task and automated Web surveillance using data mining techniques are indispensable for efficiently securing the Web against its misuse. Primarily focusing on extraction of implicit and novel patterns (knowledge) from huge databases (structured data), data mining techniques have also proven to be very effective for analyzing unstructured (text documents) and semi-structured (Web documents) data. Consequently, various research areas including text mining, web mining, and social network analysis have emerged in recent past. In the context of Web surveillance, data mining can be a potential mean to identify suspects and their activities through analyzing Web data and social networks evolved from communication networks including e-mails, enterprise portals, or social networking sites like Facebook, Twitter, etc. Web surveillance involves various aspects of analyzing different metrics, features and processes in Web and social network data which include web-content mining, web- usage mining, community detection, link prediction, position/role analysis, information diffusion, and sentiment analysis. In this talk, we propose the design of a unified knowledge-based Web surveillance framework that combines information retrieval, natural language processing and data mining techniques to identify criminals and their networks on the Web. The proposed framework would provide necessary knowledge for the intelligence agencies to identify individuals who possibly can spread criminal ideologies, criminal profiling, criminal network analysis, and visualization of criminal's activities, linkages and relationships.
