Few previous attempts have been made to address this problem in the context of big data analytics in smart cities, proposing the use of social network check-ins as a proxy for business popularity, concentrating however only on singular business types. Adding to the existing literature, we mine a large dataset of high temporal granularity check-in data for two medium-sized cities in Southern and Northern Europe, with the aim to predict the evolution of check-ins of new businesses of any type, from the moment that they appear in a social network. We propose and analyze the performance of three algorithms for the dynamic identification of suitable neighbouring businesses, whose data can be used to predict the evolution of a new business. Our SmartGrid algorithm reaches a performance of being able to accurately predict the evolution of 86\% of new businesses.}, keywords = {Location analytics, Smart Cities, Smart Economy, social networks}, doi = {10.1145/3428361.3428391}, author = {Georgios Papadimitriou and Andreas Komninos and John Garofalakis} }
