REx offers
- an optimal algorithm for the automatic extraction as a rulebase and structured visualisation as a rule diagram of a sound, thus consistent, and complete set of constructive predicate reasoning rules (implicational invariants) from arbitrary tabular data;
- a lightweight algorithm for a possible pre-processing of the data; and
-
a suit of three post-processing algorithms for
- the calculation of the complete set of consequences (deductive closure) that can be deduced from the extracted rules under a user-input finite set of elementary hypotheses by means of modus ponens,
- the set-based comparison of and operation on rulebases, and
- the model-checking of an existing input data table and rulebase including the visualisation of the check as a satisfaction table.
As a desirable side effect, Algorithm 1 also extracts and visualises a complete set of quantitatively qualified, fuzzy (not invariant) reasoning rules from its input data.
