This paper describes a context mechanism for a natural language understanding system. Since no sentence is ever perceived outside some context, it is reasonable to inquire into the nature of context as it affects the interpretation of sentence meaning at a deep conceptual level. A theory, called conceptual oyerlays, is described. This theory (1) defines C(T1,..., Ti), the context established by the meaningful sequence of thouqhts T1...Tj: (2) defines I(Tj+1, C(T1,... Tj)), the high-level interpretation of Ti+i in the context established by Ti,.,.,Ti; and (3) specifies an effective algorithm and data structure for computing I(t,K) for arbitrary thought T in context K. In particular, a prototype LISP system, EX-SPECTRE-1, which solves simple cases of I(T2., C(T1)) is described. The system is based on an expectancy/fulfillment paradigm. Expectancies are spontaneously activated by a pattern-directed invocation technique. Each expectancy implicitly references large chunks of common-sense algorithms. A collection of such implicitly activated algorithms constitutes context, and the interpretive process is one of identifying future input as steps in these algorithms. Context switching and uses of I(T,K) in a language comprehension system are discussed.
