A hidden Markov model for matching spatial networks
Autor: Benoit Costes, Julien Perret
Publikováno v: Journal of Spatial Information Science, Vol 2019, Iss 18, Pp 57-89 (2019)
Datasets of the same geographic space at different scales and temporalities are increasingly abundant, paving the way for new scientific research. These datasets require data integration, which implies linking homologous entities in a process called

Pyrite as a Microtextural and Geochemical Tracer of Ore-Forming Processes, Central Zone Orogenic Gold Deposit, Gabgaba District, Sudan
Autor: Célestine Berthier, Julien Perret, Aurélien Eglinger, Anne-Sylvie André-Mayer, Julien Feneyrol, Alexandre Voinot, Yoram Teitler, Rémi Bosc
Publikováno v: Economic Geology.
Gold deposition in structurally controlled deposits is triggered by changes in the mineralizing fluid conditions. Recent research has demonstrated that in deposits with a well-established paragenesis, the processes that control the ore-forming fluid

Historical Collaborative Geocoding
Autor: Rémi Cura, Bertrand Dumenieu, Nathalie Abadie, Benoit Costes, Julien Perret, Maurizio Gribaudi
Publikováno v: ISPRS International Journal of Geo-Information, Vol 7, Iss 7, p 262 (2018)
The latest developments in the field of digital humanities have increasingly enabled the construction of large data sets which can be easily accessed and used. These data sets often contain indirect spatial information, such as historical addresses.
