Leandro Balby Marinho, Cláudio de Souza Baptista, Thomas Sandholm, Iury Nunes, Caio Nóbrega, Jordão Araújo
2012 arXiv   pre-print
We propose to capture the geographic context of user preferences for items using a relational graph, through which we are able to derive many new and state-of-the-art recommendation algorithms, including  ...  In this paper we take a geospatial approach to determine locational preferences and similarities between users.  ...  This work was supported by a cooperation with Hewlett-Packard Brasil Ltda. using incentives of Brazilian Informatics Law (Law No. 8.2.48 of 1991).  ...

User geospatial context for music recommendation in microblogs

Markus Schedl, Andreu Vall, Katayoun Farrahi
2014 Proceedings of the 37th international ACM SIGIR conference on Research & development in information retrieval - SIGIR '14  
To this end, we propose a geospatial model that uses GPS coordinates and a cultural model that uses semantic locations (continent, country, and state of the user).  ...  We conduct experiments on a novel standardized music collection, the "Million Musical Tweets Dataset" of listing events extracted from microblogs.  ...  The user context in our work is hence addressed by taking into account musical preference and geospatial data, using a standardized collection of listening behavior mined from microblog data [4] .  ...

Resource-aware image mosaicking on networks of small-scale UAVs

Daniel Wischounig-Strucl, Bernhard Rinner
2010 Proceedings of the Fourth ACM/IEEE International Conference on Distributed Smart Cameras - ICDSC '10  
For the approximation of each image transformation Ti a trade-off between the pixel correlation and the preservation of geospatial relations is required.  ...  If all selected points are on the same elevation level or plane the similarity transformation for these points is able to preserve geospatial relations.  ...

Geospatial Web Services Discovery through Semantic Annotation of WPS

Meriem Sabrine Halilali, Eric Gouardères, Mauro Gaio, Florent Devin
2022 ISPRS International Journal of Geo-Information  
The lack of semantics in the description of services using a standard such as WPS prevents the use of such a matching process and is considered a limitation of GWS discovery.  ...  The rationale behind this work is that search engines that use appropriate semantic-based similarity measures in the matching process are more accurate in terms of precision and recall than those based  ...  All of the selected services are related to the geospatial domain.  ...
