We discuss a user-friendly system containing an operational suite of t
ools that support intelligence data processing, data visualization, hi
storical analysis, situation assessment and predictive analysis. The t
ools facilitate the study of events as a function of time to determine
situational patterns. To support this analysis, the system has variou
s data displays (e.g., timelines, maps charts, and tables) a historica
l event database, query capabilities, and expert system tools. The exp
ert system tools analyze temporal information, predict future events,
and explain decisions visually and textually. The tools are currently
installed in several military commands and intelligence agencies suppo
rting analysis ranging from strategic C-3 to counter drug. (C) 1997 El
