Giunchiglia, F. and Pecchiari, P. and Talcott, C. L. - 1994

Our ultimate goal is to provide a framework and a methodology which will allow users, and not only system developers, to construct complex reasoning systems by composing existing modules, or to add new modules to existing systems, in a “plug and play” manner. These modules and systems might be based on different logics; have different domain models; use different vocabularies and data structures; use different reasoning strategies; and have different interaction capabilities. This paper makes two main contributions towards our goal. First, it proposes a general architecture for a class of reasoning modules and systems called Open Mechanized Reasoning Systems (OMRS). An OMRS has three components: a reasoning theory component which is the counterpart of the logical notion of formal system, a control component which consists of a set of inference strategies, and an interaction component which provides an OMRS with the capability of interacting with other systems, including OMRS and human users. Second, it develops the theory underlying the reasoning theory component. This development is motivated by an analysis of state of the art systems. The resulting theory is then validated by using it to describe the integration of the linear arithmetic module into the simplification process of the Boyer-Moore system, NQTHM.
