PACT (Possibilistic Approach to Correlation and Tracking): An Approach to Combining Linguistic-Based and Probabilistic Information in Correlation and Tracking.

Abstract

The data association or correlation problem in naval ocean surveillance, and indeed in many military situraitons, is of prime interest. The work documented here represents the culminaiton of an approximately 4-year effort at NOSC for an Independent Research/Independent Exploratory Development (IR/IED) project whose objective was to improve upon previous correlation technigues which use only geolocation information. This task has been realized through the development of a decision aid, the PACT algorithm (Possibilistic Approach to Correlation and Tracking). This technique analyzes pairs of track histories or reports for possible equating. Information for each pair may be a combination of numerical statistical informalltion and linguistic-based narrative information in the form of a nonsequential, knowledge-based expert system. Keywords: Probability functions: Bivariate analysis; Measures of central tendency.
