Keynote Topic: Digital Government Ecosystems: Foundations, Architecture, Implementation
Abstract: The so-called digital transformation is perceived as the key enabler for increasing wealth and well-being by politics, media and the citizens alike. In the same vein, digital government steadily receives more and more attention. Digital government gives rise to complex, large-scale state-level system landscapes consisting of many players and technological systems, i.e., digital government ecosystems. In this talk, we systematically approach the state-level architecture of digital government ecosystems. As a case study, we look into the case of e-Estonia and its data exchange layer X-Road. We will discover the primacy of the state's institutional design in the architecture of digital government ecosystems. Based on that insight, we will establish the notion of data governance architecture, which links data assets with accountable organizations. Our investigation results into a digital government architecture framework that can help in large-scale digital government design efforts. With its focus on data, the proposed framework perfectly fits the current discussion on moving from ICT-driven to data-centric digital government.

Keynote Topic: In-Memory Computing Architectures for Big data and Machine Learning Applications
Abstract: Traditional computing hardware is working to meet the extensive computational load presented by the rapidly growing Machine Learning (ML) and Artificial Intelligence algorithms such as Deep Neural Networks and Big Data. In order to get hardware solutions to meet the low-latency and high-throughput computational needs of these algorithms, Non-Von Neumann computing architectures such as In-memory Computing (IMC) have been extensively researched and experimented with over the last five years. This study analyses and reviews works designed to accelerate Machine Learning. We investigate different architectural aspects and directions and provide our comparative evaluations. We further discuss IMC research's challenges and limitations and present possible directions.

Keynote Topic: Model-Driven Security for a Software Developer: The Case of Fine-Grained Access Control Policies
Abstract: Model-Driven Security (MDS) is a specialization of model-driven engineering for developing secure systems. In MDS, designers specify system models along with their security requirements, and use tools to generate security-related artifacts, such as access control infrastructures.
MDS has been applied with encouraging results to the development of data-centric applications. These applications focus on actions that create, read, update, and delete data stored in a database. When the data stored is sensitive, then the user's actions on these data must be controlled. If the access control policies are sufficiently simple, as in the case of role-based access control (RBAC) policies, it may be possible to formalize them declaratively. In contrast, fine-grained access control (FGAC) policies may depend not only on the user's credentials but also on the satisfaction of constraints on the data stored in the database. In such cases, authorisation checks are often implemented programmatically.
In this talk, we will first present the "theoretical" advantages of using a model-driven approach for enforcing FGAC policies in data-centric applications. Secondly, we will discuss the "practical" challenges that a software developer faces when applying a model-driven approach to enforce FGAC policies in data-centric applications. Finally, we will report on our current research projects addressing the challenges that hinder the adoption of a model-driven security in the case of FGAC policies.

Keynote Topic: Secure and Efficient Implementation of Electronic Money
Abstract: During the last years, central banks have discussed possible use of central bank digital currencies (CBDC) — electronic cash. Besides the financial and economic factors also the security and scalability of technical implementation of CBDC have been studied. Blockchain technology provides high level of security independent of the technical infrastructure and enables central banks to outsource most of the CBDC operations to private sector while still having full control over the total amount of CBDC in circulation. Scalability has been the biggest technical concern of using blockchain based CBDC.
Nation wide deployment of electronic cash requires service rate of ten to hundred thousands transactions per second while the blockchain money solutions like Bitcoin only offer the rate of few dozen transactions per second. The key of filling the scalability gap is the possibility of decomposing (sharding) the blockchain. The efficiency of decomposition highly depends on the need for inter-component communication. For example, if two accounts are in different components, then paying from one account to another requires two simultaneous operations in both components: debiting one account and crediting the other. This is technically challenging as it requires solving the atomic commit problem, which has no deterministic time solutions if possible message loss is considered. On the other hand, if we imagine a single coin given by one person to another, the only parameter that changes is the ownership of the coin. Such operation is atomic. Hence, if an electronic money solution uses coins and bills to represent money and is sharded so that some coins and bills belong to one shard and others to another shard, then every single coin payment is uni shard and does not require inter shard communication.
In this work, we first present a sharded private blockchain based CBDC solution and analyze its efficiency and security. In the second part of the work, we study how the possibility of efficient sharding depends on the choice of the money scheme (accounts, coins, etc.)

Keynote Topic: Managing the Quality of Data and Metadata for Biobanks
Abstract: Medical research requires biological material and data of documented trustworthy policy for delivering relevant and reproducible results. The management of the quality of biological samples for medical research received high attention in recent years resulting is well documented and audited standard operating procedures and standards for the documentation of various quality characteristics. We need similar efforts to establish systems, policies, procedures for assuring well documented quality characteristics of data and metadata. We review on the typical characteristics for data and for metadata and point to precise definitions of these properties. We present and discuss the requirements for managing these qualities and propose a process and the necessary tasks for biobanks to establish such a a holistic system for data quality management. The complex nature of biobanks as data producers, data providers, data mediators and data archives dealing with data from various sources and the highly sensitive nature of personal health data for quality data make them a most interesting use case for data quality management supporting both known and unknown future demands.

Keynote Topic: Deep Analytics via Learning to Reason
Abstract: Deep learning, enabled by powerful compute, and fuelled by massive data, has delivered unprecedented data analytics capabilities. However, major limitations remain. Chiefly among those is that deep neural networks tend to exploit the surface statistics in the data, creating short-cuts from the input to the output, without really deeply understanding of the data. As a result, these networks fail miserably to generalize to novel combinations. This is because the networks perform shallow pattern matching but not deliberate reasoning – the capacity to deliberately deduce new knowledge out of the contextualized data. Second, machine learning is often trained to do just one task at a time, making it impossible to re-define tasks on the fly as needed in a complex operating environment. This talk presents our recent developments to extend the capacity of neural networks to remove these limitations. Our main focus is on learning to reason from data, that is, learning to determine if the data entails a conclusion. This capacity opens up new ways to generate insights from data through arbitrary querying using natural languages without the need of predefining a narrow set of tasks.
