Research Challenges for Real Time Decision Makingin Public Sector Service Delivery:
Alex Singleton pontificates about geodemographics for about an hour...
Introduction Why Classification? An Evolving Research Themes
Commercial○ Extension Strategies – Rebranding, Diversification

Key Challenges Geodemographics 2.0
Relevance in a Depreciating Data EconomyComplexity – Time, Space and ScaleGeocomputation Challenges
Why Classification? The world is complex Simplify Reality Improve our Understanding
Help make decisionsHelp us to navigate the world

Critical Theory Arguments & Response / Lessons
Monitor, Model and Control○ Consumers are marketed identities○ Assumes consumers are not rational
Strategy Metaphor – “Simplify and Mystify” technology – purpose gaining market share○ Relates to products essentially using the same
data – just a different badge. ○ True, there is little to choose between the products○ Argument demonstrates further contempt for
consumers!Cluster Analysis – Aggregation Errors
○ True, however doesn’t entirely mitigate the valueAssumes Social identity perfectly correlates with
consumption○ Good point – bespoke classifications!
Methodology and Application Fuzzy - Discrete V Continuous Representation
Good idea – communication a problem Sensitivity to local conditions
True, compress multiple space time dimensions into core components
Modelling versus Description Yes!
Application Specific (Bespoke) Yes, but how do these become flexible and embedded for
general use. Consumer Feedback – Challenge Assignmets
Sounds good! Building Feedback into Classification
How are these verified?
Everything 2.0
Critique / KT ?
Consumption
Everything 2.0
= Accumulation of Significant External Changes
e.g.•Geoweb 2.0•Web 2.0•Wikisation of GIS•Social Networks•Crowd Sourcing•Neogeography
Challenges for Everything 2.0 Changing relationships with space & time (new channels)Rising Importance of Virtual Places (Social media, social
networks)○ Do individuals interact in real places in the same way as virtual
places? How do we reach them? Changing responses to information
Consumption (Encarta) V Production (e.g. Wiki)Static V Fluid
Clever ConsumersInformation savvy - B2B & Public
Data Economy ParadoxData Economy has never been stronger!Data Economy has never been more restricted?Lead datasets (electoral roll) increasingly marginalised
Academic Role in Geodemographics 2.0 Commercial providers will operate business as
usual until something better comes along. Why rock the boat?E.g. Legacy of K-Means - RIP
Little engagement with any critiqueSome evidence @ CACI (e.g. Health Acorn)
IMPORTANTPARTNERSHIP & KNOWLEDGE TRANSFER!
Geocomputation Challenges Data Variable Relationships & Verification Spatio-Temporal Sensitivity Processing & Analysis Dissemination
DataIndividual Level Data
○ Confidentiality & Disclosure Control○ Multiple Sources – Data Protection
Area Level Data○ Managing different scales safely
Disparate Data○ Standards – XML○ Secure - Encryption
Speed of Transfers
Relationships & Verification
Assuring Integrity Validity○ Ontological and Meta Information
E.g. How old is the data?Which data is behavioural?Which data is attitudinal?What is the coverage?
- Time, Place
Interpreting user requests○ Which variables?○ Which weight?
Spatial WeightsTemporal Weights
Spatio-Temporal Sensitivity Accounting for local variation
Spatial Interaction Models? Geographically Weighted Cluster Analysis Temporally Weighted Cluster Analysis
Normalisation which is sensitive, without detrimentally effected by outliers
Processing Which clustering algorithms?
Not K-Means Not stable, can’t efficiently optimise – why do we use
them? Maybe Partitioning Around Medoids (PAM) Maybe Intelligent Genetic Algorithms Maybe something entirely different
Building for a single purpose Multidimensional Scaling Principle Components
Processing which doesn’t collapse the geographic dimension of the data
Processing which is FAST! Safe to use – Testing!
Dissemination Live Classifications require...
Live Pen portraits○ Build automated descriptions for clusters
based on appended dataLive Maps
○ Automated Google Map GenerationOvercome tile processing limitations
Live Images○ Automated production of appropriate pictures
and collage imagery
