Spatial data are common in many scientific and commercial domains such as geographical information systems and gene/protein expression profiles. Querying for distribution patterns on such data can discover underlying spatial relationships and suggest avenues for further scientific exploration.

In this seminar, we address spatial predictive queries both in Euclidian spaces and over road networks. We provide a definition for various types of spatial predictive queries, describe current research trends, and envision future directions. We present practical application scenarios and emphasize the roadblocks that are holding industry back from the

Evaluating uncertain location-based spatial queries
Proceedings of the 2008 ACM symposium on Applied computing, 2008Location-Based Spatial Queries (LBSQ) are becoming more and more useful in location-based services such as those provided by cell-phones, Wireless LAN and GPS technologies. They support the access to information resources by taking into account the spatial context of the user when submitting the query, and the spatial location of the searched resources

The web is increasingly being used by mobile users. In addition, it is increasingly becoming possible to accurately geo-position mobile users and web content. This development gives prominence to spatial web data management. Specifically, a spatial keyword query takes a user location and user-supplied keywords as arguments and returns web objects that ...

Spatial Query Integrity with Voronoi Neighbors
IEEE Transactions on Knowledge and Data Engineering, 2013With the popularity of location-based services and the abundant usage of smart phones and GPS-enabled devices, the necessity of outsourcing spatial data has grown rapidly over the past few years.

Spatial inverse query processing
GeoInformatica, 2012Traditional spatial queries return, for a given query object q, all database objects that satisfy a given predicate, such as epsilon range and k-nearest neighbors. This paper defines and studies inverse spatial queries, which, given a subset of database objects Q and a query predicate, return all objects which, if used as query objects with the ...

Approximate Queries for Spatial Data
2013Approximation techniques for spatial data traditionally concern data capture and data representation issues. On the other hand, more recently developed approximation techniques refer to the query to be executed and not to data representation as in the the past monolithic Geographic Information Systems and for this reason they are called query-based ...

Spatial‐Scene Similarity Queries
Transactions in GIS, 2008AbstractAssessing spatial scenes for similarity is difficult from a cognitive and computational perspective. Solutions to spatial‐scene similarity assessments are sensible only if corresponding elements in the compared scenes are identified correctly. This matching process becomes increasingly complex and error‐prone for large spatial scenes as it is ...

Spatial-textual content is becoming increasingly prevalent: — Location-based services from major commercial search engines. For example, in Google Maps many (geo-referenced) points of interest--e.g., clinics, stores, tourist attractions, hotels, entertainment services, public transport, and public services--are being associated with descriptive ...
