Temporal representation of state transitions
Artificial Intelligence for Engineering Design, Analysis and Manufacturing, 1999This paper describes a knowledge-based temporal representation of state transitions for industrial real-time systems. To allow expression of uncertainty, we shall define fluents as disjuncts of positive/negative time-varying properties. A state of the world is represented as a collection of fluents, which is usually incomplete in the sense that ...

Updating representations of temporal intervals
Experimental Brain Research, 2015Effectively engaging with the world depends on accurate representations of the regularities that make up that world-what we call mental models. The success of any mental model depends on the ability to adapt to changes-to 'update' the model. In prior work, we have shown that damage to the right hemisphere of the brain impairs the ability to update ...

Representation of temporal information
International Journal of Computer & Information Sciences, 1982The use of the temporal logic formalism for representing information is reviewed. Two languages are introduced corresponding to two different ways of viewing information: as an assertion about properties of objects (syntactic view), or as a set of objects (semantic view). We define the semantics of the languages in terms of a model that generalizes the

Representation of Temporal Unawareness
2002In this paper we are concerned with the problem of designing of a conceptual framework for the construction of a flexible query answering mechanism that is adequate for selecting useful answers to queries, considering a multi-source and conflicting community of information sources.

Uncertantty in temporal representation and reasoning
International Journal of Computer Mathematics, 1999The paper presents an approach of managing temporal knowledge under imprecision or uncertainty, based on possibility theory and fuzzy logic. Temporal uncertainties are modelled in terms of possibility theory with imprecise time instants, imprecise time intervals and imprecise time durations.

Temporal representation and reasoning in medicine
Artificial Intelligence in Medicine, 2006Temporal representation and reasoning is a very challenging research topic in several areas of computer science: among them, we mention here databases, artificial intelligence, theoretical computer science, computational linguistics, real time systems, and medical informatics.

Compact representations of temporal databases
The VLDB Journal, 2018This paper investigates the storage compactness of temporal merges. A temporal merge is a joint representation of a set of snapshots of the same database at different points in time. An axiomatic requirement for temporal merges is that each individual snapshot must be derivable from it. We first show that the usual temporal extension of a database is a

Temporal representation for multimedia systems
Proceedings Third International Workshop on Temporal Representation and Reasoning (TIME '96), 2002The paper focuses on temporal representation for multimedia systems. On the basis of an interval-based indeterministic synchronization model the authors propose a new generalized synchronization model (GSM), which has fewer, more powerful interval operators. They then outline a description language paradigm as a preferred approach to specify multimedia

Qualitative representation of spatio-temporal knowledge
Journal of Visual Languages & Computing, 2018Abstract In this paper we present PCT (Position-Connection-Time), a formalism capable of representing spatio-temporal knowledge in a qualitative fashion. This framework achieves an expressive power comparable to other classic spatial relation formalisms describing common topological and directional spatial relations.
