- Rules are the basic information type in ART-CEE. They consist of two
- conditions or facts having a cause and effect relationship. 'If two
- and two then four' is such a rule. If the condition 'two plus two'
- exists, then 'four' follows.
-
- ART-CEE breaks all rules down into 'subject' and 'predicate' phrases.
- These phrases are stored along with numbers describing the strength of
- relationship between them. A number of 0 means there is no cause and
- effect relationship at all, and a number of 100 means absolute cer-
- tainty that a cause and relationship always exists.
-
- The 'if' and 'then' in the rules are not stored. Leading articles
- ('a', 'an' and 'the') also are dropped from subject and predicate. No
- punction is acceptable upon entering a rule.
-
- The program can store up to 60 subjects/predicates and up to 3540
- relationships between them. Processing time and complexity increase
- by the square of the number of subjects actually stored.
