On searching and indexing sequences of temporal intervals

O Kostakis, P Papapetrou - Data mining and knowledge discovery, 2017 - Springer
In several application domains, including sign language, sensor networks, and medicine,
events are not necessarily instantaneous but they may have a time duration. Such events …

Distance measure for querying sequences of temporal intervals

O Kostakis, P Papapetrou, J Hollmén - Proceedings of the 4th …, 2011 - dl.acm.org
Time series representations are not always rich enough to describe the temporal activity, for
instance, when the context and the relations of the observed elements are of interest …

IBSM: Interval-based sequence matching

A Kotsifakos, P Papapetrou, V Athitsos - Proceedings of the 2013 SIAM …, 2013 - SIAM
Sequences of event intervals appear in several application domains including sign

Abide: querying time-evolving sequences of temporal intervals

O Kostakis, P Papapetrou - Advances in Intelligent Data Analysis XVI: 16th …, 2017 - Springer
We study the problem of online similarity search in sequences of temporal intervals; given a
standing query and a time-evolving sequence of event-intervals, we want to assess the …

Artemis: Assessing the similarity of event-interval sequences

O Kostakis, P Papapetrou, J Hollmén - … 5-9, 2011, Proceedings, Part II 22, 2011 - Springer

Subsequence search in event-interval sequences

OK Kostakis, AG Gionis - Proceedings of the 38th International ACM …, 2015 - dl.acm.org
We study the problem of subsequence search in databases of event-interval sequences, or
e-sequences. In contrast to sequences of instantaneous events, e-sequences contain events …

Efficient bitmap-based indexing of time-based interval sequences

J Roh, S Hwang, BK Yi - Information sciences, 2012 - Elsevier
In this paper, we discuss similarity searches for time series data represented as interval
sequences. For instance, the time series of phone call records can be represented by time …

Similarity search for interval time sequences

BK Yi, JW Roh - International Conference on Database Systems for …, 2004 - Springer
Time sequences, which are ordered sets of observations, have been studied in various
database applications. In this paper, we introduce a new class of time sequences of which …

Similarity search of bounded tidasets within large time interval databases

P Meisen, D Keng, T Meisen… - 2015 International …, 2015 - ieeexplore.ieee.org
Searching for similar entities within a database is a common and a daily, billions of times,
