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

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.

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 factorsEvangelos Kalampokis, Efthimios Tambouris and Konstantinos Tarabanis (XXX) "Understanding the Useof Social Media for Predictions", [submitted for evaluation] © Information Systems Lab, University of Macedonia

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

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

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

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

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

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
