On point-duration networks for temporal reasoning

We present here a point-duration network formalism which extends the point algebra model to include additional variables that represent durations between points of time. Thereafter the new qualitative model is enlarged for allowing unary metric constraints on points and durations, subsuming in this way several point-based approaches to temporal reasoning. We deal with some reasoning tasks withi...

Point-Based Approaches to Qualitative Temporal Reasoning

We address the general problem of finding algorithms for efficient, qualitative, point-based temporal reasoning over a set of operations. We consider general reasoners tailored for temporal domains that exhibit a particular structure and introduce such a reasoner based on the series-parallel graph reasoner of Delgrande and Gupta; this reasoner is also an extension of the TimeGraph reasoner of G...

Temporal Reasoning and Bayesian Networks

This work examines important issues in probabilistic temporal representation and reasoning using Bayesian networks (also known as belief networks). The representation proposed here utilizes temporal (or dynamic) probabilities to represent facts, events, and the effects of events. The architecture of a belief network may change with time to indicate a different causal context. Probability variat...

Reasoning with Disjunctive Fuzzy Temporal Constraint Networks

The Disjunctive Fuzzy Temporal Constraint Network (DFTCN) model is a framework that allows reasoning with fuzzy qualitative and quantitative complex temporal constraints. However, its general complexity is exponential. In this work, we review methods that can reduce this complexity, based on graph topology and preprocessing. The final goal is to integrate all these methods into a general tool f...

Causal Networks and Nonmonotonic Temporal Reasoning

We show that the theory of causation that makes use of causal networks is intimately related to nonmonotonic temporal reasoning. Applying the theory of causal networks in a logical context yields a new approach to nonmonotonic temporal reasoning that can be proven to be a generalization and/or correction of many existing ones, and that provides new insights on the old question on how, and wheth...
