The flexible socio spatial group queries

Bishwamittra Ghosh, Mohammed Eunus Ali, Farhana M. Choudhury, Sajid Hasan Apon, Timos Sellis, Jianxin Li
2018 Proceedings of the VLDB Endowment  
In this paper, we propose Top k Flexible Socio Spatial Group Query (Top k-FSSGQ) to find the top k groups w.r.t. multiple POIs where each group follows the minimum social connectivity constraints.  ...  A socio spatial group query finds a group of users who possess strong social connections with each other and have the minimum aggregate spatial distance to a meeting point.  ...  To address the above limitations, we propose a novel Top-k Flexible Socio Spatial Group Query (Top k-FSSGQ) that finds top k groups with flexible group sizes for a given set of POIs (meeting points).  ...

Storing routes in socio-spatial networks and supporting social-based route recommendation

Yerach Doytsher, Ben Galon, Yaron Kanza
2011 Proceedings of the 3rd ACM SIGSPATIAL International Workshop on Location-Based Social Networks - LBSN '11  
Queries over a socio-spatial network glean information on users, in correspondence with their location history, and retrieve geographical entities in association with the users who frequently visit these  ...  Considering these associations as edges that connect users of a social network to geographical entities on a spatial network yields an integrated socio-spatial network.  ...  In a socio-spatial network there are five different types of nodes-users, buildings, road segments, routes and spatial groups.  ...

Querying geo-social data by bridging spatial networks and social networks

Yerach Doytsher, Ben Galon, Yaron Kanza
2010 Proceedings of the 2nd ACM SIGSPATIAL International Workshop on Location Based Social Networks - LBSN '10  
An important contribution of this work is in illustrating the usefulness and the feasibility of maintaining and querying integrated socio-spatial graphs.  ...  We consider two implementations of a socio-spatial graph storage-one implementation uses a relational database system as the underline data storage, and the other employs a graph database system.  ...  In this paper we present a set of operators that serve as the building blocks of a socio-spatial query language over a joined socio-spatial graph.  ...

How Do Scholars Communicate the 'Temporary Turn' in Urban Studies? A Socio-Semiotic Framework

Robin A. Chang
2021 Urban Planning  
A socio-semiotic framework helps unpack the production of meanings as well as symbols channeled through the scholarly institutionalization of TU.  ...  Through a meta-research, or research about research approach employing socio-semiotics and bibliometric analyses for the first time in relation to TU, I clarify the increasing scholarly attention to urban  ...  Acknowledgments The author would like to thank Meg Holden for questioning the 'temporary' in TU. Gratitude also goes to Martin Eckert for sharing enthusiasm for the R language and environment.  ...

Crossing boundaries: mapping spatial dynamics of urban phenomena at micro scale to support urban management in the Amsterdam urban region

Els Veldhuizen, Karin Pfeffer
2016 Belgeo  
Finally, the RMA tool offers high flexibility in terms of thematic queries or adjusting the presentation and design of maps; in other tools interactivity is often limited to indicator and theme selection  ...  Second, spatial concentrations are datadriven flexible objects: not bound to administrative boundaries and determined by the data of the phenomenon under consideration.  ...  Although administrative boundaries have always played an important role in map making, they are not meaningful for revealing the spatial dynamics of urban phenomena that vary within wards, cross ward boundaries  ...
