A Personalized and Approximated Spatial Keyword Query Approach [PDF]
IEEE 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 ...

Top-K Collective Spatial Keyword Queries [PDF]
IEEE 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

Joint Top-K Spatial Keyword Query Processing [PDF]
IEEE 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.

On Nearby-Fit Spatial Keyword Queries [PDF]
IEEE Transactions on Knowledge and Data Engineering, 2020 Geo-textual data is ubiquitous nowadays, where each object has a location and is associated with some keywords. Many types of queries based on geo-textual data, termed as spatial keyword queries , have been proposed, and are to find optimal object(s) in terms of both its (their) location(s) and keywords.

ISPRS International Journal of Geo-Information, 2023 A new spatial keyword group query method is proposed in this paper to address the existing issue of user privacy leakage and exclusion of preferences in road networks. The proposed query method is based on the IGgram-tree index and minimum hash set.

Research on Time-Aware Group Query Method with Exclusion Keywords
ISPRS International Journal of Geo-Information, 2023 Aiming at the problem that the existing spatial keyword group query problem did not consider the query requirements with exclusion keywords and time attributes, a time-aware group query problem with exclusion keywords (TEGSKQ) is proposed for the first ...

Collective spatial keyword querying [PDF]
Proceedings of the 2011 ACM SIGMOD International Conference on Management of data, 2011 With the proliferation of geo-positioning and geo-tagging, spatial web 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.

Why Questions on Time-Aware Spatial Keyword Queries in Traffic Networks
IEEE Access, 2022 Time-aware spatial keyword queries in traffic networks ( $TSKQT$ ) aim to retrieve top- $k$ result objects based on the ranking score considering spatial proximity, textual relevance, and temporal similarity simultaneously. However, due to inappropriate
