Semantizing geodemographies• Support for metadata• To enhance information from sensors• Information about geodemographic indices• Decisions which influence city behavior MTSR 2012

13.
Ontologies• Step 1 – Reflecting and standarizing available information for building systems (GCI) – They provide us with spatial and digital knowledge• Step 2 – High level of information fusion (future social changes) – Knowlege about and for urban systems MTSR 2012

14.
Extracting an ontologyGeodemographic systems: – Datasets apt to be statistically treated – Systems to be interpreted by expert scientists – Semiformal representation of a geodemographic conceptualizationBuilding an ontology:Case study. MOSAIC MTSR 2012

15.
MOSAIC: Segmentation System http://www.experian.co.uk/ MTSR 2012

16.
MOSAIC (by Experian Group)• Comprises a range of segmentation systems• Statistical techniques of classification, GIS and software for database management• Groups: demographic and socio-economical features (age, ethnicity, affluence, accommodation, etc.)• Segmentation of consumers: prospective, recruitment, loyalty MTSR 2012

17.
• Detailed descriptions of a range of sociodemographic environments• From the ontological point of view, ideal types• Explained by estatistical data• Expert scientists interpret data but do not characterize each class MTSR 2012

18.
Limitations• MOSAIC definitions present difficulties to be translated into metadata – Variance across individuals – Variance of requirements for belonging – Lack of critical requirements (features not included in definitions because of sufficent statistical data have not been provided). Examples: urban /rural nedighborhoods, tax rates, size of houses, etc. MTSR 2012

19.
• MOSAIC definition make use of properties – Experts interpret but there are no data• Class is not fully defined by Data – Axioms can not be expressed• Object Properties vs Data Properties• MOSAIC definitions vs MOSAIC Data – Weakening definitions: set of constrains MTSR 2012

Methodology1. Analysis of geodemographic system – Types – Data – Expert’s interpretation2. Interpretation – Tipes as classes – Data as (object or data) properties on classes – Interpretation of segmentation3. Ontology engineering – Hierarchy construction – Axiomatization of classes by means the characterization of properties – Interpretation of segmentation expressed by axioms MTSR 2012

Applications of SG• Geodemographic Ontology -> Social Knowledge – Influence all the processes of informational collect, interpretation and feedback – Urban Informatics scope and city management – Specialiced decisions and applications MTSR 2012

24.
• Life cycle of knowledge in Smart Cities • Acquisition • Verification • Documentation • Decision• Enriched not only by Sociodemographic ontologies• Reasoning on processed knowledge MTSR 2012

25.
Innovation Lines on Smart city features:• Urban planning/landscape systems (decision urban interventions)• Knowledge-based market for social products and services• Analysis of digital information increases urban resilience• Developing social or community apps MTSR 2012

26.
Conclusions• Main lines of geodemographic ontology design and engineering• Limitations for developing geodemographic systems from KE• Ontologies provide GCI with Knowledge• Metadata enrich urban subsystems MTSR 2012

• Subsystems of an urban system MTSR 2012
