Due to the COVID-19 pandemic the conference and workshop were held virtually. The 10 papers were thoroughly reviewed and selected from 15 submissions, and discuss a range of topics including: knowledge discovery, biological data, cyber security, cyber-physical system, machine learning, knowledge graphs, information retriever, data base, and artificial intelligent Notes International conference proceedings "Due to the pandemic and for the safety of all participants as well as other restrictions preventing travel and gatherings, this year DEXA was held as a virtual conference in the Western European time zone."--Preface Includes author index Subject Database management -- Congresses Expert systems (Computer science) -- Congresses Artificial intelligence.
