Monroe 2 is a new version of the Monroe random plan generator originally developed by Nate Blaylock and described in his papers (with James Allen),

• Generating artificial corpora for plan recognition. In: Ardissono, L., Brna, P., Mitrovic, A. (Eds.), 2005, User Modeling 2005. Springer, Edinburgh, pp. 179–188.

Some discussion of Monroe 2 may be found in my paper "Plan Recognition for Network Analysis: Preliminary Report," which was presented at the 2018 Plan, Activity, and Intent Recognition (PAIR) workshop.

The Monroe2 system itself is contained in the src subdirectory. It contains the original Monroe sources (by permission of the original author, Nate Blaylock) with the revisions made by SIFT to transform it into Monroe2.

Monroe2 is a Common Lisp program, which is built on top of the SHOP3 open source planning system. Monroe2 may be loaded using the ASDF system definition facility.

The MonroePlanCorpus-1.0 subdirectory contains Nate's original Monroe plan recognition corpus.

We hope to make documentation available going forward, but have not had time thus far.
