search, local intent search, and spatio-temporal intent search.  ...  We view social media data as a constant stream of data points, each containing text with spatial and temporal contexts.  ...  The challenges can be broken into three contexts: temporal, spatial, and spatio-temporal. We focus on data-centric challenges in each context and cover example applications.  ...

Managing uncertain spatio-temporal data

Thomas Bernecker, Tobias Emrich, Hans-Peter Kriegel, Andreas Zuefle, Lei Chen, Xiang Lian, Nikos Mamoulis
2011 Proceedings of the 2nd ACM SIGSPATIAL International Workshop on Querying and Mining Uncertain Spatio-Temporal Data - QUeST '11  
Although there exists a wide range of applications dealing with uncertain spatio-temporal data, there is no solution for efficient management of such data available yet.  ...  The main challenge here is to unfold this potential by developing new algorithms based on these models. In addition, we give examples of interesting spatiotemporal queries on uncertain data.  ...  A small sample of interesting spatio-temporal queries on uncertain data is given in the following.  ...

Range Search on Uncertain Trajectories

Liming Zhan, Ying Zhang, Wenjie Zhang, Xiaoyang Wang, Xuemin Lin
2015 Proceedings of the 24th ACM International on Conference on Information and Knowledge Management - CIKM '15  
In practice, a large portion of spatio-temporal data in the above applications is generated with low sampling rate and the uncertainty arises between two subsequent observations of a moving object.  ...  To make sense of the uncertain trajectory data, it is critical to properly model the uncertainty of the trajectories and develop efficient range search algorithms on the new model.  ...  Finally we have the formal definition of the spatio-temporal range search on uncertain trajectories. Problem Statement.  ...

Querying Uncertain Spatio-Temporal Data

Tobias Emrich, Hans-Peter Kriegel, Nikos Mamoulis, Matthias Renz, Andreas Zufle
2012 2012 IEEE 28th International Conference on Data Engineering  
In this work, we present a framework for efficiently modeling and querying uncertain spatio-temporal data.  ...  Based on these concepts we propose efficient solutions for different probabilistic spatio-temporal queries.  ...  Then, we provide details on modeling uncertain spatio-temporal data with time dependencies (Section IV).  ...

Mining Probabilistic Frequent Spatio-Temporal Sequential Patterns with Gap Constraints from Uncertain Databases

Yuxuan Li, James Bailey, Lars Kulik, Jian Pei
2013 2013 IEEE 13th International Conference on Data Mining  
In this paper, we focus on pattern mining for uncertain sequences and introduce probabilistic frequent spatial-temporal sequential patterns with gap constraints.  ...  Such patterns are important for the discovery of knowledge given uncertain trajectory data.  ...  Our work tackles the problem of mining spatio-temporal sequential patterns where the input data is uncertain. A.  ...

Indexing uncertain spatio-temporal data

2012 Proceedings of the 21st ACM international conference on Information and knowledge management - CIKM '12  
To the best of our knowledge, this is the first approach that supports query evaluation on very large uncertain spatio-temporal databases, adhering to possible worlds semantics.  ...  The advances in sensing and telecommunication technologies allow the collection and management of vast amounts of spatio-temporal data combining location and time information.  ...  Section 3.5), and (iv) a pointer oid to the exact uncertain spatio-temporal object description (raw object data).  ...

Spatio-Temporal Access Methods: Part 2 (2003 - 2010)

Long-Van Nguyen-Dinh, Walid G. Aref, Mohamed F. Mokbel
2010 IEEE Data Engineering Bulletin  
In Part 2, we give an overview and classification of spatio-temporal access methods that are published between the years 2003 and 2010.  ...  In spatio-temporal applications, moving objects detect their locations via location-aware devices and update their locations continuously to the server.  ...  These queries may execute on past, current, or future time data. A large number of spatio-temporal index structures has been proposed to support spatio-temporal queries efficiently.  ...

Visualizing Uncertainty in Cultural Heritage Collections [article]

Florian Windhager, Velitchko Andreev Filipov, Saminu Salisu, Eva Mayr
2018 EuroVis Workshop on Trustworthy Visualization  
We introduce the PolyCube system as a visualization framework which provides four different perspectives on the geo-temporal origins of cultural collection data, including coordinated multiple views, animation  ...  With specific regard to this multi-perspective framework we develop options to visualize spatio-temporal uncertainty and discuss ways and means of their coherent implementation.  ...  Spatio-Temporal Data Uncertainty (STDU) Spatio-temporal data uncertainty results from the combination of the above-mentioned dimensions and thus inherits all definitions and distinctions from temporal  ...

Preschoolers search for hidden objects

Jeffrey M. Haddad, Yuping Chen, Rachel Keen
2011 Journal of Experimental Child Psychology  
The issue of whether young children use spatio-temporal information (e.g., movement of objects through time and space) and / or contact-mechanical information (e.g., interaction between objects) to search  ...  Three-year-olds were found to use the valid spatio-temporal cue exclusively, and seemed to ignore the contact mechanical cue.  ...  We thank Daniel Johnson, Dana Alhaffar and Lydia Baosithong for help in data collection and scoring. We also thank Lisa Oakes for suggesting this study as an important follow-up to our previous work.  ...

Balloon

Hechen Liu, Markus Schneider
2011 Proceedings of the 1st ACM SIGSPATIAL International Workshop on Spatial Semantics and Ontologies - SSO '11  
The spatio-temporal uncertainty is an inherent feature of moving objects.  ...  This paper introduces such a model which represents the spatio-temporal uncertainty in the near future. We introduce an uncertainty model called the balloon model specifically for future movements.  ...  Similarly, spatio-temporal query languages are built on top of SQL as well.  ...
