DFIG Level 5 (User Refinement) issues supporting Situational Assessment Reasoning

Subsequent revisions to the JDL model modified definitions for model usefulness that stressed differentiation between fusion (estimation) and sensor management (control). Two diverging groups include one pressing for fusion automation (JDL revisions) and one advocating the role of the user (User-Fusion model). The center of debate is real-world delivery of fusion systems which requires presenting information fusion results for knowledge representation (fusion estimation) and knowledge reasoning (control management). The purpose of the paper is to highlight the need of Users, with individual differences, facilitated by knowledge representations to reason about user situational awareness (SA). This position paper highlights: (l) Addressing the user in system management / control (2) Assessing information quality (metrics) to support SA (3) Evaluating Fusion systems to deliver user info needs, (4) Planning knowledge delivery for dynamic updating (5) Designing SA interfaces to support user reasoning
