Predicate naming refers to the practice of assigning meaningful and descriptive names to predicates in logic programming languages like Prolog. A predicate, in this context, is a relation that can be either true or false for a given set of arguments. The name of a predicate, along with its arity (the number of arguments it takes), defines its unique identity.

Effective predicate naming is crucial for the readability and maintainability of logic programs. When predicates are named intuitively, it becomes easier for programmers to understand the intended meaning and functionality of different parts of the code. For example, a predicate named parent(X, Y) clearly suggests that X is a parent of Y, whereas a name like p(X, Y) would be ambiguous.

Good predicate names are typically concise, descriptive, and adhere to conventions within the logic programming community. They often use lowercase letters and underscores for separation, although specific style guides may vary. The goal is to avoid overly long or cryptic names that hinder comprehension.

The importance of predicate naming extends to debugging and collaboration. Well-named predicates make it easier to trace the execution flow, identify errors, and for multiple developers to work on the same codebase without constant clarification. While the functional behavior of a predicate is determined by its clauses, the name provides the essential semantic context. Therefore, investing time in choosing appropriate predicate names is a fundamental aspect of good logic programming practice.
