Efficient Retrieval of the Top-k Most Relevant Spatial Web Objects
TLDR
This paper proposes a new indexing framework for location-aware top-k text retrieval that takes into account both location proximity and text relevancy. Expand
Indexing the positions of continuously moving objects
TLDR
This paper proposes a novel, R*-tree based indexing technique that supports the efficient querying of the current and projected future positions of such moving objects. Expand
A foundation for representing and querying moving objects
TLDR
We propose to present such time-dependent geometries as attribute data types with suitable operations, that is, to provide an abstract data type extension to a DBMS data model and query language to yield a powerful language for querying spatio-temporal data, including moving objects. Expand
Discovery of convoys in trajectory databases
TLDR
This paper formalizes the concept of a convoy query using density-based notions, in order to capture groups of arbitrary extents and shapes. Expand
Query and Update Efficient B+-Tree Based Indexing of Moving Objects
TLDR
A number of emerging applications of data management technology involve the monitoring and querying of large quantities of continuous variables, e.g., the positions of mobile service users. Expand
Capturing the Uncertainty of Moving-Object Representations
TLDR
Spatiotemporal applications, such as fleet management and air traffic control, involving continuously moving objects are increasingly at the focus of research efforts. Expand
Collective spatial keyword querying
TLDR
We study the problem of retrieving a group of spatial web objects such that the group's keywords cover the query's keywords and such that objects are nearest to the query location and have the lowest inter-object distances. Expand
Novel Approaches to the Indexing of Moving Object Trajectories
TLDR
The domain of spatiotemporal applications is a treasure trove of new types of data and queries, as well as algorithms to process those. Expand
A consensus glossary of temporal database concepts
TLDR
This document contains definitions of a wide range of concepts specific to and widely used within temporal databases. Expand
