The high degree of datification and connectivity embedded in a Smart City demands tools and mechanisms for data manipulation, knowledge extraction and representation that facilitate the extraction of meaningful insights. Clearly, Data Science can make enormous contributions to the development of Smart Cities, especially when it comes to gather and process information, combined with the capabilities of machine learning. In this regard, this paper discusses the use of Data Science methodologies and machine learning techniques to Smart City management aspects such as infrastructures, public safety and health, citizens’ empowerment, transportation, etc. and presents a number of practical cases in the context of Smart Cities in València, Spain.
