  1. Extraneous Embedded Knowledge andAdaptive Programming An ACM SIGSOFT 2000 paper

  2. What is EEK? • We refer to knowledge of the external world within a component (e.g., a method or class) that is not conceptually required for the behavior of that component as extraneous embedded knowledge (EEK).

  3. Example • A method for checking whether each class in a class dictionary is defined exactly once (or imported). • What is EEK? Knowledge about the details of a class dictionary for class dictionaries.

  4. Analogy to human conversation • Interpret messages differently depending on the implicit context. • omission • alteration • traverse(Strategy s, Visitor v) is interpreted very differently depending on the ObjectGraph-object to which message is sent.

  5. Analogy to human conversation • traverse(Strategy s, Visitor v) is interpreted very differently depending on context. • explain(politics) is interpreted very differently depending on context. You take the background of the audience into account.
