- Online data mining services for dynamic spatial databases I: system architecture and client applicationsPublication . Costa, Manuel; Sousa, Inês; Fonseca, Alexandra; Henriques, Diana; Rosa, Paulo; Franco, Ivan; Capeta, Nuno; Teixeira, Luis Miguel Lopes; Cardoso, Jorge C. S.; Carvalho, VascoThis paper describes online data mining services for dynamic spatial databases connected to environmental monitoring networks. These services can use Artificial Neural Networks as data mining techniques to find temporal relations in monitored parameters. The execution of the data mining algorithms is performed at the server side and a distributed processing scheme is used to overcome problems of scalability. To support the discovery of temporal relations, two other families of online services are made available: vectorial and raster visualization services and a sonification service. The use of this system is illustrated by the DM Plus client application and the SNIRH Data Mining Web site. The sonification service is described and illustrated in the part II paper.
- Online data mining services for dynamic spatial databases II: air quality location based services and sonificationPublication . Teixeira, Luis Miguel Lopes; Barbosa, Álvaro; Cardoso, Jorge C. S.; Carvalhos, Vasco; Costa, Manuel; Sousa, Inês; Franco, Ivan; Fonseca, Alexandra; Henriques, Diana; Rosa, PauloThis paper introduces online data mining services for dynamic spatial databases associated with environmental monitoring networks. In particular, it describes an application that uses these services with sonification for air quality location based information services to the general public. The data mining services use Artificial Neural Networks, to find temporal relations in the monitored parameters. The execution of the algorithms performed at the server side and a distributed processing scheme is used to overcome problems of scalability. In addition, two other families of web services are made available to support the discovery of temporal relations: vectorial and raster map? services and a sonification service. The map services were implemented in DM Plus, a client application presented in part I. The sonification service is described in this paper and illustrated through an application study that implements an air quality index with sonification for mobile phones.
