Intelligence applications have to process massive amounts of data in order to extract relevant information. This includes archived historical data as well as continuously arriving new data. We propose a novel architecture that addresses this problem – the Cornell Knowledge Broker. It will not only support knowledge discovery, but also security, privacy, information exchange, and collaboration.

In this paper we examine the robustness of existing models of agent decision making which rely on the assumption of common knowledge. The research we report on involves testing equilibria predicted by traditional, common-knowledge intensive models in laboratory settings wherein the underlying common knowledge assumptions are violated in a specified manner. This approach provides insight into wh...

Knowledge and information transfer have become important ingredients for an organisation’s competitive advantage. Knowledge management has emerged as an overarching strategy to enhance knowledge creation, information transfer, utilisation, and reticulation in order to generate innovation and improve organisational performance. Part of this strategy involves the creation of Communities of Practi...

Four foreign exchange spot rate series, recorded on an hourly basis for a six-month period in 1986 are examined. A seasonal GARCH model is developed to describe the time-dependent volatility apparent in the percentage nominal return of each currency. Hourly patterns in volatility are found to be remarkably similar across currencies and appear to be related to the opening and closing of the worl...

Organisations need networks to leverage external knowledge, particularly for SMEs with their limited resources. Organisations use networks for knowledge sharing to foster innovation. This use of networks bears risks like the unwanted spill-over of knowledge. Consequently, organisations need to balance sharing and protecting knowledge. While scholars have extensively investigated the sharing per...
