HPKB Movement Analysis Ontology
Draft of February 9, 1998

Jon Doyle

The following summarizes the main points of the ontology developed by the Movement Analysis group participants in the second HPKB Battlespace challenge problem SME meeting. The shape of the structure given below was worked out on February 6, 1998 by Eric Domeshek, Eric Jones, John Gennari, Bill Long, myself, and the UMass representative (my apologies for forgetting the name). I've added a bit of annotation in spots, and based the following on notes taken by Bill Long and myself.

The main entities described below are sites, units, occupations (of sites by units), movements, trends, and reports. Each of these entities may have internal and external parameters.

The aim is that reports appear in the same form, whether they are system inputs given in the stream of simulated intelligence reports or system outputs given in the stream of notifications. Input reports will provide order of battle information about relevant units, information about known sites, and observations of vehicles, movements, and sites. Output reports (notifications) will mainly concern sites sites, movements, and trends. Input and output reports may be partial. Input reports typically will identify the time at which an event occurs with some precision. Output reports may start out very partial and abstract, but be followed up by refined reports of increasing detail and accuracy.

This ontology only covers most of the main points; some main points and many details may have been omitted. Some are under development by other HPKB groups.
