Peircean Decision Aid

Software ·
OSTI ID:1231202
The Peircean decision aid (PDA) is a decision support architecture and embedded functionality that supports a decision maker in very complex environments dealing with massive amounts of disparate data, information and knowledge. The solution generated is a hybrid system solution employing a number of technologies that are based on Peircean reasoning, modal logic, and formal concept analysis. The system convolves data/information with knowledge to create a virtual belief state that is passed to a decision maker for consideration. The system can capture categorized knowledge or it can inductively learn or acquire new knowledge from suites of observations. Captured knowledge is used to abductively generate hypotheses that are potential explanations to observations or collected data. The zero order modal logic architecture is designed to augment knowledge update and belief revision and can be extended to include disjunctive screening of collected data. While intended to be a library for integration into a decision support architecture it possesses a basic stand-alone GUI for use as an analysis support tool.
