A generalization of Allen's interval-based approach to temporal reasoning is presented. The
notion of 'conceptual neighborhood'of qualitative relations between events is central to the …

We introduce a new subclass of Allen's interval algebra we call “ORD-Horn subclass,” which
is a strict superset of the “pointisable subclass.” We prove that reasoning in the ORD-Horn …

The notion of time is uniquitous in any activity that requires intelligence. In particular, several
important notions like change, causality, action are described in terms of time. Therefore, the …

Starting with an updated description of Allen's calculus, the book proceeds with a description
of the main qualitative calculi which have been developed over the last two decades. It …

Allen gives an algebra for representing qualitative temporal information about the
relationships between pairs of intervals. In this paper, we address a fundamental reasoning …

Abstract Temporal Constraint Satisfaction is an information technology useful for
representing and answering queries about temporal occurrences and temporal relations …

The calculus of time intervals defined by Allen has been extended in various ways in order
to accomodate the need for considering other time objects than convex intervals (eg. time …

Implementations of Allen's interval-based temporal logic and a recently developed
simulation system for reasoning about space and time, both require the use of transitivity …

An attempt is made to integrate three well-known formalisms of knowledge representation:
terminological logic in the tradition of KL-ONE, the temporal logic of Shoham, and Allen's …

Qualitative spatial relations are symbol abstractions of geometric representations, which
allow computational analyses independent of, but consistent with, graphical depictions. This …
