Work started with a procedural representation, a small block of code for 
each action.  Each method was quite similar so a "domain-specific" 
language was abstracted with properties stored in a triple store and a 
small number of variables in rules with binding in the course of 
narrative "parsing."  Working on the <a 
href="http://csc.media.mit.edu/">OpenMind</a> corpus axioms were 
collected as prototypical situations described by triples.  Work 
continued in this vein until 10,000 situations were described.  Linking 
of situations with common triples (spreading activation) explored the 
declarative aspects of reasoning.  Assessment of ots show fully a third 
of triples were based on nouns and verbs, so the bulk of the corpus was 
marked up in these terms.  Finallly common event were typed up in a 
procedural format centered on various kinds of thing.  Work since then 
has focused for tools for presentation (lpkb's social skills).
