In this paper, we present a technology platform that can be customized to create a wide range of corporate radar applications that can turn the Web into a systematic source of business insight. This platform integrates a combination of established AI technologies – i.e. semantic models, natural language processing, and inference engines – in a novel way. We present two prototype corporate radars built using this platform: the Business Event Advisor, which detects threats and opportunities relevant to a decision maker's organization, and the Technology Investment Radar which assesses the maturity of technologies that impact a decision maker's business. The Technology Investment Radar has been piloted with business users, and we present encouraging initial results from this pilot.
