This paper is a limited overview of a preliminary research task carried out for the National Security Agency (NSA) having to do with developing a basic understanding of the notions and concepts of intent, intentionality, and intentional behavior. These notions clearly have significant implications for intelligence analysis and especially predictive intelligence; modern-day asymmetric threats and operations other than war make the understanding and exploitation of these notions yet more urgent. The projects eventual goal is to develop and conduct research-oriented experiments with a prototype automated intent-estimating aid based on fused SIGINT-type data, as a path toward developing deeper knowledge about these concepts. This research effort is in support of NSA's WARGODDESS program which is developing a SIGINT-Fusion capability for operational use. As will be seen from the paper, this first study effort started with a review of the quite-basic research literature in the philosophical, cognitive, and legal arenas, with the purpose of evolving possibly new but minimally consistent and synthesized understanding of these basic concepts. It will also be seen that such understanding will not come easily and will require a serious continuing research program if optimal progress is to be made.
