Scalable collective spatial keyword query

2015 31st IEEE International Conference on Data Engineering Workshops, 2015
Spatial 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 ...

Density-based spatial keyword querying

Future Generation Computer Systems, 2014
With 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 ...

Spatial Keyword Querying

2012
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 ...

Interactive Spatial Keyword Querying with Semantics

Proceedings of the 2017 ACM on Conference on Information and Knowledge Management, 2017
Conventional 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.

Density Based Collective Spatial Keyword Query

2012 Eighth International Conference on Semantics, Knowledge and Grids, 2012
Geographic objects with descriptive text are gaining in prevalence in many web services such as Google map. Spatial keyword query which combines both the location information and textual description stands out in recent years. Existing works mainly focus on finding top-k Nearest Neighbours where each node has to match the whole querying keywords.

Efficient Spatial Database Keyword Query Search

2020
Spatial database keyword search is very useful in many real-time applications. Traditional m closest keyword algorithm is not scalable for very large datasets and moreover, existing algorithms are mainly based on inter-object distances only. This paper aimed to develop a process that can do the best keyword search.

Interactive Top-k Spatial Keyword queries

2015 IEEE 31st International Conference on Data Engineering, 2015
Conventional 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.

Spatial Keyword Queries

2012
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 ...

Multiple Query Point Based Collective Spatial Keyword Querying

2019
Spatial 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.

Time-Aware Boolean Spatial Keyword Queries

IEEE Transactions on Knowledge and Data Engineering, 2017
With 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.
