Undefined terms involving the application of partial functions and operators are common in program specifications and in discharging proof obligations that arise in design. One wa...
This paper presents a point based spatio-temporal rst order logic for representing the qualitative and quantitative spatial temporal knowledge needed to reason about motion in a t...
We introduce an extension of Description Logics (DLs) for representing and reasoning about contextualized knowledge. Our formalism is inspired by McCarthy’s theory of formalizing...
We assume that safety of information stored in a database depends on the reliability of the agents who have performed the insertions in the database. We present a logic S to repres...
