Efficient Processing of Spatial Group Keyword Queries
ACM Transactions on Database Systems, 2015With the proliferation of geo-positioning and geo-tagging techniques, spatio-textual objects that possess both a geographical location and a textual description are gaining in prevalence, and spatial keyword queries that exploit both location and textual description are gaining in prominence.

Semantic-aware top-k spatial keyword queries
World Wide Web, 2017 The fast development of GPS equipped devices has aroused widespread use of spatial keyword querying in location based services nowadays. Existing spatial keyword query methodologies mainly focus on the spatial and textual similarities, while leaving the ...

Spatial keyword query processing
Proceedings of the VLDB Endowment, 2013Geo-textual indices play an important role in spatial keyword querying. The existing geo-textual indices have not been compared systematically under the same experimental framework. This makes it difficult to determine which indexing technique best supports specific functionality.

Scalable collective spatial keyword query
2015 31st IEEE International Conference on Data Engineering Workshops, 2015Spatial keyword queries have been widely studied recently, along with the emergence of large amount of geo-textual data. We consider the problem of scalable collective spatial keyword queries in this paper. Such query has a wide spectrum of applications; for instance, to find the best (nearest) area to organize a friend get-together where bars ...

Interactive Spatial Keyword Querying with Semantics
Proceedings of the 2017 ACM on Conference on Information and Knowledge Management, 2017Conventional spatial keyword queries confront the difficulty of returning desired objects that are synonyms but morphologically different to query keywords. To overcome this flaw, this paper investigates the interactive spatial keyword querying with semantics.

Collective Keyword Query on a Spatial Knowledge Base
IEEE Transactions on Knowledge and Data Engineering, 2019The conventional works on spatial keyword queries for a knowledge base focus on finding a subtree to cover all the query keywords. The retrieved subtree is rooted at a place vertex, spatially close to a query location and compact in terms of the query keywords.

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 ...

Density-based spatial keyword querying
Future Generation Computer Systems, 2014With the rocket development of the Internet, WWW(World Wide Web), mobile computing and GPS (Global Positioning System) services, location-based services like Web GIS (Geographical Information System) portals are becoming more and more popular. Spatial keyword queries over GIS spatial data receive much more attention from both academic and industry ...

Interactive Top-k Spatial Keyword queries
2015 IEEE 31st International Conference on Data Engineering, 2015Conventional top-k spatial keyword queries require users to explicitly specify their preferences between spatial proximity and keyword relevance. In this work we investigate how to eliminate this requirement by enhancing the conventional queries with interaction, resulting in Interactive Top-k Spatial Keyword (ITkSK) query.
