A Hidden Markov Model For Matching Spatial Networks, Benoit Costes, Julien Perret
A Hidden Markov Model For Matching Spatial Networks, Benoit Costes, Julien Perret
Journal of Spatial Information Science
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 data matching that remains a challenging task, despite a quite substantial literature, because of data imperfections and heterogeneities. In this paper, we present an approach for matching spatial networks based on a hidden Markov model (HMM) that takes full benefit of the underlying topology of networks. The approach is assessed using four heterogeneous datasets (streets, roads, railway, and hydrographic networks), showing that the HMM algorithm …
