DCluster: Geospatial Analytics with PoI Identification

Abstract: The generation of geospatial data is an inherent aspect for several applications that aim to track people, automobiles, or other mobile objects. Mining information from this type of data is a crucial factor for the development of Smart Cities. In many cases, it can help improve human mobility and the quality of citizens. In this sense, there is a growing demand for systems capable of extracting information from several data types, including the geospatial one. In this work, we present DCluster, a web system th… Show more

“…We rely on a privacy metric based on data dispersion, i.e., POI, that belong to the data distortion metrics. State-ofthe-art POI metrics are offline [22,19,33,9], they require the whole trace to be computed. Our paper contributes in presenting the first privacy metric based on POI that can be computed online.…”

“…Existem propostas que utilizam GNNs [Capanema et al, 2022] e aprendizado por reforço para escolher a próxima célula. A modelagem é feita considerando-se uma abstração da O-RAN onde RBSs e UEs são nós do grafo e a qualidade dos enlaces sem-fio é representada pelos pesos dos enlaces do grafo.…”

“…É importante ressaltar que, um dos datasets utilizados contém check-ins de usuários de uma rede social, de modo que cada estabelecimento visitado é considerado como um PoI. Por outro lado, a segunda base de dados utilizada contém trajetórias de GPS de usuários móveis e, dessa forma, foi necessário utilizar o algoritmo de identificação de PoIs descrito em (Capanema et al, 2021a(Capanema et al, , 2019Capanema & Silva, 2021). A componente de camada RNN indica o comportamento recente do usuário, enquanto a componente GNN indica o comportamento global/geral do usuário em termos da sua mobilidade entre PoIs e as suas respectivas categorias.…”
