Knowledge Discovery from Moving Objects (MOVE) (End date: October 2013)
The main objective of the Action is to develop improved methods for knowledge extraction from massive amounts of data regarding moving objects.
This Action aims to build a network for collaboration that leads to the improvement of ICT methods for knowledge extraction from massive amounts of data about moving objects. This knowledge is essential to substantiate decision making in public and private sectors. Moving object data typically include trajectories of concrete objects (e.g. humans, vehicles, animals, and goods), as well as trajectories of abstract concepts (e.g. spreading diseases). While movement records are nowadays generated in huge volumes, methods for extracting useful information are still immature, due to fragmentation of research and lack of comprehensiveness from monodisciplinary approaches. Overcoming these limitations calls for COST-like networking.
In response to a strong expression of interest from the academic, industrial, and user communities, this Action will empower the development of substantial and widely applicable methods in mobility analysis, focusing on representation and analysis of movement, including spatio-temporal data mining, and visual analytics. Results will be demonstrated through showcases for decision makers. Researchers from various subdomains in computer and geographic information sciences will join domain specialists from a broad range of relevant applications, from courier services and transportation to ecology, and epidemiology, among others. This will make Europe a central stakeholder in an emerging key domain.

Semantic Enrichment of 3D City Models for Sustainable Urban Development (End date: June 2012)
Many urban or environmental models are defined with the objective of helping practitioners and stakeholders in their decision-making processes. Models which represent in 3 dimensions the geometric elements of a city are called 3D city models. These models are increasingly used in different cities and countries for an intended wide range of applications beyond mere visualization. Such uses are made possible by adding semantics to the geometrical aspects, leading to semantically enriched 3D city models. Furthermore, in the perspective of a sustainable development, cities ought to be studied in a comprehensive manner taking into account many interrelations between various urban issues. This can be achieved by identifying and extracting the knowledge underlying in related data and models. Using ontologies is a robust way to achieve the semantic enrichment of 3D city models as well as their interoperability with other urban models, so that they become an effective matrix of urban knowledge in a perspective of sustainability.
This Action will
(1) create an integrative platform based on semantically enriched 3D city models,
(2) use an ontology-based methodology that could be reused
(3) assess the usability of the integrated platform for planning and decision-making.
