Book ChapterDOI
Continuous nearest neighbor search
TL;DR: This paper proposes techniques that solve the problem by performing a single query for the whole input segment, and proposes analytical models for the expected size of the output, as well as the cost of query processing, and extend out techniques to several variations of the problem.
Proceedings ArticleDOI
Group nearest neighbor queries
TL;DR: This work proposes several algorithms for finding the group nearest neighbors efficiently and extends their techniques for situations where Q cannot fit in memory, covering both indexed and nonindexed query points.
Journal Article
Indexing and Retrieval of Historical Aggregate Information about Moving Objects
TL;DR: This paper argues that the spatial and temporal dimensions should be modeled as a combined dimension on the data cube and present data structures, which integrate spatiotemporal indexing with pre-aggregation, and develops methods that utilize the proposed structures for efficient execution of ad-hoc group-bys.
