Reasoning about generalized intervals: Horn representability and tractability

P. Balbiani, J.-F. Condotta, G. Ligozat
Proceedings Seventh International Workshop on Temporal Representation and Reasoning. TIME 2000  
This paper organizes the topologic forms of the possible relations between generalized intervals.  ...  Working out generalized interval algebra on the pattern of point algebra and interval algebra, it introduces the concept of Horn representability just as the one of convexity.  ...  Without doubt, the model of the points designed by Vilain and Kautz [13] and the model of the intervals elaborated by Allen [1] are the better known models for reasoning about time.  ...

Interval talks at the first el paso shell oil symposium

A Language for Planning with Statistics [article]

Nathaniel G. Martin, James F. Allen
2013 arXiv   pre-print
Inferences about the validity of the approximations can be made using interval estimation.  ...  Such probabilities are subject to error, so the planner must introspect about their validity. Inferences about the probability of these events can be made using statistics.  ...  It develops an event-based first order language using temporal intervals and confidence intervals for reasoning about plans.  ...

An Interval-Based Approach for Reasoning About Land use Change Trajectories

Adeline M. Maciel, Lubia Vinhas, Gilberto Camara, Michelle C. A. Picoli, Rodrigo A. Begotti
2018 IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium  
We use an interval-based approach and the concept of events to reason about land use changes trajectories resulting in a formalism that allows users to express queries about the land use.  ...  The method contributes with a tool to help scientists and policy makers to reason about land use change.  ...  Its core is an extension and improvement of the interval-based approach by Allen's [8] to build a general calculus to reason about land use change trajectories, where we use events to represent different  ...

Temporal reasoning based on semi-intervals

Christian Freksa
1992 Artificial Intelligence  
A generalization of Allen's interval-based approach to temporal reasoning is presented.  ...  We demonstrate the advantages of reasoning on the basis of semi-intervals: 1) semi-intervals are rather natural entities both from a cognitive and from a computational point of view; 2) coarse knowledge  ...  The basic elements of Allen's theory are intervals corresponding to events (rather than points corresponding to instants), qualitative relations between these intervals, and an algebra for reasoning about  ...

Timing is everything. Time-oriented clinical information systems

Y Shahar, C Combi
1998 Western Journal of Medicine  
Representing, maintaining, querying, and reasoning about time-oriented clinical data is a major theoretical and practical research area in medical informatics.  ...  We also explore the two primary methodological and theoretical paths research has taken in the past decade: temporal reasoning and temporal data maintenance.  ...  A episode holds during an interval, during which a predefined property (evaluated by reasoning about several events) holds.  ...

Interval Temporal Logic in General-Purpose Situational Simulations

Eddy M. Rojas, Amlan Mukherjee
2005 Journal of computing in civil engineering  
This paper also illustrates how this new paradigm facilitates the implementation of a reasoning mechanism that can be used by a software agent to perceive present actions and predict the future evolution  ...  simulations of construction management processes and construction operations shows that commonly used discrete event simulation paradigms are unsuitable for representing actions and events in interactive general  ...  Finally, in developing a general purpose, simulation paradigm it is necessary to be able to represent and reason about broad classes of problems.  ...

Informal Inferential Reasoning: Interval Estimates of Parameters

Theodosia Prodromou
2013 International Journal of Statistics and Probability  
This research examined the informal inferential reasoning of senior secondary school students (age 17) when engaged in a computer-simulated sampling activity calling for the estimation of population parameters  ...  A number of strategies for forming an interval estimate emerged.  ...  Thus his interval became generally between about 30 and 88.  ...

Unification of geospatial reasoning, temporal logic, & social network analysis in event-based systems

Jans Aasman
2008 Proceedings of the second international conference on Distributed event-based systems - DEBS '08  
This paper is about a new type of event database that enables efficient reasoning about things, people, companies, relationships between people and companies, and about places and events.  ...  On top of this event database we implemented libraries for RDFS++ logic reasoning, for geospatial and temporal capabilities, and an extensive social network analysis package.  ...  Temporal Reasoning Our temporal reasoning is based on James Allen's Interval Logic [9] . This logic looks at all the 13 ways two temporal intervals can relate to each other.  ...
