compfindp(sentence,dataset,ruleset) → boolean
The compfindp subroutine takes as arguments a sentence (called the query), a dataset, and a ruleset. It uses the facts in the dataset and the rules in the ruleset to derive an instance of the query. If it succeeds, it returns true; otherwise, it returns false.
