Diversified Spatial Keyword Query on Topic Coverage
2018Spatial keyword queries are widely used in location based service systems nowadays to find the spatial web object people need. The returned objects usually are relevant to the query but not diversified each other. Motivated by this, we study the problem of diversified spatial keyword query on topic coverage, which returns k relevant objects close to ...

Time-Aware Boolean Spatial Keyword Queries
IEEE Transactions on Knowledge and Data Engineering, 2017With advances in geo-positioning technologies and mobile internet, location-based services have attracted much attention, and spatial keyword queries are catching on fast. However, as far as we aware, no prior work considers the temporal information of geo-tagged objects.

Processing spatial keyword query as a top-k aggregation query
Proceedings of the 37th international ACM SIGIR conference on Research & development in information retrieval, 2014We 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. Existing solutions for the problem are based on either using a combination of textual and spatial indexes or using specialized hybrid indexes

Answering Spatial Approximate Keyword Queries in Disks
2015Spatial approximate keyword queries consist of a spatial condition and a set of keywords as the fuzzy textual conditions, and they return objects labeled with a set of keywords similar to queried keywords while satisfying the spatial condition. Such queries enable users to find objects of interest in a spatial database, and make mismatches between user

A spatial keyword evaluation framework for network-based spatial queries
Proceedings of the 21st ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2013An increasing number of spatial keyword query techniques that return qualified objects based on a comprehensive consideration of spatial and keyword constraints have been presented in the literature. Due to the complexity of the solutions to spatial keyword queries, systems that can effectively demonstrate the mechanisms will attract interest from the ...

An Efficient Packing Algorithm for Spatial Keyword Queries
2012With the increase of location-based services, Web contents are being geo-tagged, and spatial keyword queries that retrieve objects satisfying both spatial and keyword conditions are gaining in prevalence. Unfortunately, the state-of-the-art packing algorithms only focus on spatial relationship, and they are not fit for the spatial keyword queries.

Multiple Query Point Based Collective Spatial Keyword Querying
2019Spatial keyword search is a useful technique to enable users find the spatial web object they prefer. Since they objects spatially close to the query point may not fulfill all query objectives, collective spatial keyword query aims to retrieve a group of objects that can cover all required query keywords while properly located in spatial.
