Designing fusion systems for decision support in complex dynamic situations calls for an integrated human-machine information environment, in which some processes are best executed automatically while for others the judgment and guidance of human experts and end-users are critical. Thus decision making in such environment requires constant information(More)
The overall goal of this paper is to provide a formal ontological analysis of threat. In particular, this paper discusses the formal ontological structure of threats as integrated wholes possessing three interrelated parts: intentions, capabilities and opportunities, and shows how these elements stand to one another, as well as to states of vulnerability.(More)
The purpose of situation and impact assessment is to infer and approximate the critical characteristics of the environment in relation to the particular goals, capabilities and policies of the decision makers. The process of situation and impact assessment involves dynamic generation of hypotheses about the states of the environment and evaluation of their(More)
Maritime surveillance involves gathering and integrating a large amount of heterogeneous information of variable quality to provide diverse decision makers with reliable knowledge about situations and threats. This requires information processing at all fusion levels while taking into account contextual information. Context is especially important for(More)
The paper presents an information fusion-based approach to one of the most challenging problems in mammogram interpretation: the problem of characterizing mammographic microcalcifications as benign or malignant. There are two categories of methods typically used for designing decision aids for diagnosis of microcalcifications: computer vision methods(More)
Harbor surveillance is a critical and challenging part of maritime security procedures. Building a surveillance picture to support decision makers in detection of potential threats requires the integration of data and information coming from heterogeneous sources. Context plays a key role in achieving this task by providing expectations, constraints and(More)
