A system and method is provided for representation of a real world problem situation. The system includes a computer software process which can acquire or accept a set of input data. The input data generally includes seed facts and user entered facts. The set of input data represents real world objects which pertain to a real-world problem situation. The computer software process generates new data. The new data consists of additional not-previously-known facts about the real-world problem situation. The additional not-previously known facts include acquired facts and reasoned facts. The computer software process utilizes a fact structured representation method. The fact structured representation method represents a first group of facts about a problem situation. It also represents a rule structured representation method for representing a first group of rules about a class of problem situations. The computer software process also represents a plurality of causal features of the problem situation so that a reasoning process results. The reasoning process is characterized as performing some elements of deep reasoning.
