Dear  Kaoutar,

I recommend the book:

by Ozge Yalciner Ercoskun (Gazi University, Turkey)

Maybe you can check this link of Beth Simone Noveck' s talk at the International City/County Managers Association, Boston, MA 2013, where she focused on the opportunity for those who govern to use a variety of new technologies to tap the intelligence and expertise of their communities:

'(...) Sentiment analysis is another form, a kind of very specific form of big data if you will. It’s one that sometimes more accessible to people. Its mining Twitter and Facebook looking for what people say about me in order to improve how I deliver services. The DC government is starting to do this now: you can look at grade.dc.gov. They are using sentiment analysis to see what people are saying about the delivery of government services in Washington and grading their agencies based on what they are reading in social media as a way of driving improved performance and seeing where the problems are.(...)'

What exactly are you trying to locate with sentiment analysis?

I would also recommend you the Vakali, A., Anthopoulos, L. and Srdjan, K. (2014). ). Smart Cities Data Streams Integration: experimenting with Internet of Things and social data flows. In the Proceedings of WIMS '14 Proceedings of the 4th International Conference on Web Intelligence, Mining and Semantics (WIMS14)

You might have a look at the publications of Prof. Christoph Hölscher, now at ETH Zürich

thank you for your suggestions, are there any more ?
