Data exchange for Digital Government: Where are we heading?

Abstract: In all countries, we currently see major efforts in digital transformation initiatives. The United Nations e-Government Survey 2020 puts a strong emphasis on data, which makes sense, given the huge progress in big data and data science in the last decade. The UN survey distinguishes between data-informed, data-driven and data-centric approaches to digital government. Actually, Gartner defined the notion of data-centric government already in 2014. Still, today, we are far away from such data-centric government. How comes? How to shape the next generation of e-government technologies? In service of such and similar questions, we analyze a series of important data exchange technologies: the Estonian data exchange layer X-Road, the European federated data infrastructure GAIA-X, the European Blockchain Services Infrastructure (EBSI), and the IoT data management solution FIWARE.

Towards High-Quality Big Data: A Focus on Time

Abstract: Data are being generated, collected, and analyzed today at an unprecedented scale, and data-driven decision making is sweeping through all aspects of society. As the use of big data has grown, so too have concerns that poor-quality data, prevalent in large data sets, can have serious adverse consequences on data-driven decision making. Responsible data science thus requires a recognition of the importance of veracity, the fourth “V” of big data. In this talk, we first present a vision of high-quality big data, with a focus on time, and highlight the substantial challenges that the first three V’s, volume, velocity, and variety, bring to dealing with veracity in long data. We present the FIT Family of adaptive, data-driven statistical tools that we have designed, developed, and deployed at AT&T for continuous data quality monitoring of a large and diverse collection of continuously evolving data. These tools monitor data movement to discover missing, partial, duplicated, and delayed data; identify changes in the content of spatiotemporal streams; and pinpoint anomaly hotspots based on persistence, pervasiveness, and priority. We conclude with lessons relevant to long data quality that are cause for optimism.

A perspective on prescriptive and reinforcement learning

Abstract: Prescriptive Learning (PL) combines the decision-making framework from operations research with machine learning capabilities, to carry out prediction-driven decision making.  In various forms, reinforcement learning and control theory are manifestations of PL.  The ambit of PL is growing. After describing our work in air cargo and traffic signal optimization using PL, we will discuss possibilities of the use of PL in database management systems and information retrieval.
