The recent technological advances on telecommunications create a new reality on mobility sensing. Nowadays, we live in an era where ubiquitous digital devices are able to broadcast rich information about human mobility in real-time and at a high rate. Such fact exponentially increased the availability of large-scale mobility data which has been popularized in the media as the new currency, fueling the future vision of our smart cities that will transform our lives. The reality is that we just began to recognize significant research challenges across a spectrum of topics. Consequently, there is an increasing interest among different research communities (ranging from civil engineering to computer science) and industrial stakeholders on build knowledge discovery pipelines over such data sources. However, such availability also raise privacy issues that must be considered by both industrial and academic stakeholders on using these resources. This workshop intends to be a top-quality venue to bring together transdisciplinary researchers and practitioners working in the related topics from multiple areas such as Data Mining, Machine Learning, Numerical Optimization, Public Transport, Traffic Engineering, Multi-Agent Systems, Human-Computer Interaction and Telecommunications, among others. The ultimate goal of this venue is to evaluate not only the theoretical contribution of the methodology proposed in each research work, but also its potential deployment/impact as well as its advances with respect to the State-of-the-Art/State-of-the-Practice in the domains of the related applications. The venue will take place at ECML/PKDD 2018, the largest and most reputed Machine Learning/Data Mining conference in Europe. The accepted formats are regular papers or demonstrations of production-ready software on related topics (soft max. limi of 20 pages on Springer’s LNCS format for both). Both formats will be presented orally at the workshop. The review process is single-blind. All the accepted regular papers will be invited to submit an Extended version to a Special Issue (edited by the workshop’s organization). The journal that will host this Special Issue is still on discussion with its editorial board.
