The Role and Challenges of Data in the Digitalization Era

In an increasing digital world, information systems deal with complex and diverse data with many associated challenges for modeling, accessing, and manipulating data. We have progressed from traditional data management, to the era of big data, and now to an era where the digitalization of applications and processes are having a profound impact on business and society. Proper management of data is critical in the era of digitalization, as is archiving it for current and future use. However, many traditional challenges of data management remain, requiring a deep understanding of the use of data in the digital world. This paper compares data management in the era of digitalization to traditional data management. Challenges related to data semantics, data structure and syntax, and data use are analyzed and illustrated for an emerging technology, blockchain, which is heavily data-dependent. Continuing data challenges and future research directions are proposed.

Next Generation Modeling Environments

Conceptual models play an important role in many organizations. They serve as tools for communication and documentation, are often a central part in process improvement initiatives, and are key to the development and evolution of information systems. Existing modeling tools typically support end users in a rather generic and non-personalized manner. However, users not only differ in their modeling expertise and the challenges they encounter while modeling, but also in their preferences. Therefore, they would benefit from a new generation of modeling environments that are highly personalized and adapt themselves to users’ needs. This keynote presents a vision of such modeling environments with a focus on process modeling. It highlights this potential with several examples from our research and touches upon challenges that come with the development of next generation modeling environments.

Multi-dimensional Complexity

We live in a  world of increasing complexity.  We work in domains that use words like systems, systems of systems, cross disciplinary engineering, interdisciplinary engineering, transdisciplinary engineering, man machine interfaces, autonomy and AI.  Furthermore, we see the need to move outside of engineering itself into design, art, ethics, risk, biology, national and international law.  We live on the tech frontier—but frontiers can be dangerous.  How do we cope?  How to we tame the growing complexity we ourselves create? What tools, tactics, techniques and strategies can we use to function responsibly, ethically, and creatively?

State of Permissionless and Permissioned Blockchains: Myths and Reality

Abstract. It has been a decade since the concept of blockchain was invented as the underlying core data structure of the permissionless or public Bitcoin cryptocurrency network. Since then, several cryptocurrencies, and associated concepts like tokens and ICOs have emerged. After much speculation and hype, significant number of them have become problematic or worthless, even though some countries have embraced them! The permissionless blockchain system Ethereum emerged by generalizing the use of blockchains to manage any kind of asset, be it physical or purely digital, with the introduction of the concept of Smart Contracts. Over the years, numerous myths have developed with respect to the purported utility and the need for permissionless blockchains. The adoption and further adaptation of blockchains and smart contracts for use in the permissioned or private environments is what I consider to be useful and of practical consequence. Hence, the technical aspects of only private blockchain systems will be the focus of my ER 2019 keynote. Along the way, I will bust many myths associated with permissionless blockchains. I will also compare traditional database technologies with blockchain systems’ features and identify desirable future research topics.

Keyword Search over RDF Datasets

Keyword search is typically associated with information retrieval systems, especially those designed for the Web. By contrast, database management systems offer sophisticated query languages to access structured data. It is up to the database applications to implement user interfaces that hide the complexity of the query language. Keyword search applications over relational databases and RDF datasets have also been studied for some time as an alternative to this traditional database interface design practice. In particular, an RDF keyword-based query processing tool can be categorized as schema-based, when it exploits the RDF schema to compile a keyword-based query into a SPARQL query, or as graph-based, when it directly explores the RDF dataset. Hitting the middle ground, there are also approaches that explore or summarize the RDF graph to guide the translation of keyword-based queries into SPARQL queries. This talk first addresses the problem of implementing keyword search for RDF datasets that do not necessarily feature an RDF schema. Then, it introduces the question of serendipitous search as a strategy to diversify answers. Finally, if briefly covers the especial case of the entity relatedness problem, which refers to the problem of exploring an RDF dataset to discover and understand how two entities are connected.
