Augmenting Open Government Data with Social Media Data

Augmenting Open Government
Data with Social Media Data Evangelos Kalampokis, EfthimiosTambouris, Michael Hausenblas and KonstantinosTarabanis W3C USING OPEN DATA Workshop 19-20 June 2012, Brussels © Information Systems Lab – 2012

Open Gov Data
(OGD) and Social Media Data (SMD) Open Government Data (OGD) Social Media Data (SMD) – Come in various formats – Come in various formats – Come in large numbers – Come in large numbers – Mostly are created by the – Mostly are created by Social public sector Media users – Some are open – Some are open – Are objective – Are subjective – Are used for new value-added – Are used for new value-added services services and research (e.g. for predictions) © Information Systems Lab, University of Macedonia

Our Research Agenda
Aim: Investigate and exploit the integration of OGD and SMD Steps: 1. Understanding OGD 2. Understanding SMD 3. OGD/SMD Integration 4. Proof-of-concept: UK elections 2010 © Information Systems Lab, University of Macedonia
6.
1. Understanding OGD:
A Classification Scheme 24 official OGD initiatives were classified based on that framework in 2010 (this classification may now have changed) Kalampokis, E., Tambouris, E., Tarabanis, K.: A Classification Scheme for Open Government Data: Towards Linking Decentralized Data. International Journal of Web Engineering and Technology 6(3), 266–285 (2011) © Information Systems Lab, University of Macedonia
7.
2. Understanding the
Use of Social Media Data: An Analysis Framework list of important factors Based on the list of important review of ~60 relevant factors scientific publications list of important factors list of important factors Evangelos Kalampokis, Efthimios Tambouris and Konstantinos Tarabanis (XXX) "Understanding the Use of Social Media for Predictions", [submitted for evaluation] © Information Systems Lab, University of Macedonia
8.
3. Integrating Open
Government and Social Data Some challenges: – Stage Model (putting everything in context) – Identify relevant datasets – Transforming noisy SMD into high quality structured data (e.g. using NER etc.) – Integrating data based on common elements (e.g. using Linked data, etc.) – Platform for data analytics (dashboard) – Explanatory and predictive models – Meaningful case studies!! © Information Systems Lab, University of Macedonia

11.
4. Proof of
Concept (UK elections of 2010) What OGD and SMD reveal about UK elections 2010? We envisage two complementary views: one objective (based on OGD) and one subjective (based on SMD) as well as one integrated © Information Systems Lab, University of Macedonia
12.
Objective view based
on OGD (UK elections 2010) Data source (X-axis): Children in poverty per parliament constituency (data.gov.uk) (Y-axis): UK elections 2010 Labours results per constituency Labours won 7 out of 200 constituencies with % of children in poverty below 17% Labours won 74 out of 77 constituencies with % of children in poverty over 30% © Information Systems Lab, University of Macedonia
13.
Subjective view based
on SMD (UK elections 2010) Data source: Tweets about UK elections (#ge2010, #ukelection, #election20 10 and #ge10) during the last month before elections (moving average k = 4 days) Data source: Poll results (YouGov) © Information Systems Lab, University of Macedonia
14.
Integrated view based
on OGD + SMD Work still in progress (results to be announced soon) From a technological view, we aim to develop a dashboard like the following: Objective view Subjective view Integrated view (based on OGD) (based on SMD) (based on OGD+SMD) © Information Systems Lab, University of Macedonia
15.
Conclusions and Future
Work OGD and SMD have a huge potential for added value services besides “trivial” apps This requires significant advances in exploiting OGD, SMD and their integration. Our aim is to provide the infrastructure (framework, methods, tools, platforms) necessary to exploit this potential. © Information Systems Lab, University of Macedonia
