Maintaining knowledge about temporal intervals

by James F. Allen - COMMUNICATION OF ACM , 1983
"... The problem of representing temporal knowledge arises in many areas of computer science. In applications in which such knowledge is imprecise or relative, current representations based on date lines or time instants are inadequate. An interval-based temporal logic is introduced, together WiUl a comp ..."

Discovering frequent arrangements of temporal intervals

by Panagiotis Papapetrou, George Kollios, Stan Sclaroff - In Proceedings of the 5th IEEE International Conference on Data Mining (ICDM’05 , 2005
"... In this paper we study a new problem in temporal pattern mining: discovering frequent arrangements of temporal intervals. We assume that the database consists of sequences of events, where an event occurs during a time-interval. The goal is to mine arrangements of event intervals that appear frequen ..."

Visualisation of Temporal Interval Association Rules

by Chris P. Rainsford, John F. Roddick , 2000
"... . Temporal intervals and the interaction of interval-based events are fundamental in many domains including medicine, commerce, computer security and various types of normalcy analysis. In order to learn from temporal interval data we have developed a temporal interval association rule algorithm ..."

Imprecise temporal interval relations

by Steven Schockaert, Martine De Cock, Etienne E. Kerre - In Proceedings of the 6th International Workshop on Fuzzy Logic and Applications , LNAI 3849 , 2006
"... Abstract. When the time span of an event is imprecise, it can be represented by a fuzzy set, called a fuzzy time interval. In this paper we propose a representation for 13 relations that can hold between intervals. Since our model is based on fuzzy orderings of time points, it is not only suitable t ..."

Mining sequences of temporal intervals

by Steffen Kempe - In 10th Europ. Conf. on Principles and Practice of Knowledge Discovery in Databases , 2006
"... Abstract. Recently a new type of data source came into the focus of knowledge discovery from temporal data: interval sequences. In contrast to event sequences, interval sequences contain labeled events with a tem-poral extension. However, existing algorithms for mining patterns from interval sequenc ..."

Temporal Intervals 1

by Takuro Yonezawa, Jin Nakazawa, Goro Kunito, Tomohiro Nagata
"... This paper proposes a smart object event modeling language. By attaching sensor nodes to everyday objects, users can augment the objects digitally and apply the objects into various services. When creating such smart object services, users should define events, such as beverage of a cup turns cold o ..."

pen and a notebook, they need to use a programming language. To define such complex event easily without complex programming language, we present a new event description language called SOEML based on temporal relation among simple events. We also provide users a visual interface to support users

A representation for collections of temporal intervals

by Bruce Leban, David D. Mcdonald, David R. Forster - In Proceedings of AAAI , 1986
"... Temporal representation and reasoning are necessary components of systems that consider events that occur in the real world. This work explores ways of considering collections of intervals of time. This line of research is motivated by related work being done by our research group on appointment sch ..."

Probabilistic Temporal Interval Networks: Extended Version

by Vladimir Ryabov, André Trudel, Vladimir Ryabov, André Trudel , 2004
"... A Probabilistic Temporal Interval Network is a constraint satisfaction problem where the nodes are temporal intervals and the edges are uncertain interval relations. We attach a probability to each of Allen’s basic interval relations. An uncertain relation between two temporal intervals is represent ..."
