Geo-Social Top-k and Skyline Keyword Queries on Road Networks

open access: yesSensors, 2020
The rapid growth of GPS-enabled mobile devices has popularized many location-based applications. Spatial keyword search which finds objects of interest by considering both spatial locations and textual descriptions has become very useful in these ...

A Personalized and Approximated Spatial Keyword Query Approach

open access: yesIEEE Access, 2020
With the universal use of GPS and rapid increase of spatial Web objects, spatial keyword query has been widely used in Location-Based Services (LBS). Most of the existing spatial keyword query processing models only support location proximity and strict ...

Joint Top-K Spatial Keyword Query Processing [PDF]

open access: yesIEEE Transactions on Knowledge and Data Engineering, 2012
Web users and content are increasingly being geopositioned, and increased focus is being given to serving local content in response to web queries. This development calls for spatial keyword queries that take into account both the locations and textual descriptions of content.

Processing Spatial Keyword Query as a Top-k Aggregation Query [PDF]

open access: yes, 2014
We examine the spatial keyword search problem to retrieve objects of interest that are ranked based on both their spatial proximity to the query location as well as the textual relevance of the object’s keywords.

Spatial keyword query processing

open access: yesProceedings of the VLDB Endowment, 2013
Geo-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.

Top-K Collective Spatial Keyword Queries

open access: yesIEEE Access, 2019
With the advent of a large number of spatial-textual data, collective spatial keyword queries have been widely studied in recent years. However, the collective spatial keyword query studied so far usually looks for only a set of objects. In addition, the

A Query Understanding Framework for Earth Data Discovery

open access: yesApplied Sciences, 2020
One longstanding complication with Earth data discovery involves understanding a user’s search intent from the input query. Most of the geospatial data portals use keyword-based match to search data.
