The iLOC ontology is a generic approach for in-house wayfinding and location description supported by Linked Open Data.
The project is a civil effort to create a trackable representation of local government decisions and their history.
Neticle mention graph in which summarizes the key topics, the related sentiments and the connections in large amount of social data about a brand or company.
Query federation over Linked Data sources has gained a significant attention in the last couple of years.
The Internet of Things (IoT) with billions of connected devices has been generating an enormous amount of data every hour.
A very large number of public and private data sets are available from local governments and are a huge resources for Europe and for the cities. In most cases, the citizens use worldwide operators such as Google, OpenStreet Map, Here, TomTom, etc., to get information while they found it in most cases insufficient for who is leaving in the city. The local governs have much more detailed data, some of them are public other are private and accessible only as authenticated services and thus not easily accessible for worldwide operators. These open and private valuable data are too fragmented and not accessible for the final users, citizens or companies that use to exploit them for providing services. They could be a source of revenues and are becoming a big business for local specific services, too small and complex to be of interest for worldwide operators.
In order to solve the above described problems and provide a unique point of access for interoperable data of a city metropolitan area we have realized (http://www.disit.org/km4city ) an ontological model called Km4City and well formalized and open grounded on ontology standards. In addition, a set of tools for data ingestion, management, aggregation, indexing and for producing in short time web and mobile applications have been realized and make accessible. The solution is presently today in place in Florence and whole Tuscany area. A smarter navigation can be performed from http://servemap.disit.org while mobile applications are accessible on Google Play and Apple Store.
The Km4City solution is covering multiple domains for citizens integrating aspects of mobility and transport, with energy, banks, parking, commercial, bike paths, delay for busses, garden areas, etc.
