Local Models Semantics, or Contextual Reasoning = Locality + Compatibility

Fausto Giunchiglia1
November 4, 1998

Abstract

In this paper we present a new semantics, calles "Local Models Semantics" and use it to provide a foundation to reasoning about contexts. This semantics captures and makes precise the two main intuitions underlying contextual reasoning:
  1. Reasoning is "local" and uses only part of what is potentially available (e.g., what is known, inference procedures). This "part" is what we call "context".
  2. There is "compatibility" among different contexts. What is true in one context is in part dependent on what is true in other contexts.
We validate our semantics one two important examples: viewpoints and beliefs.
