This volume contains short papers presented at ISWC2020: 19th International Semantic Web Conference November 1-6, 2020, held as a global online conference. The conference was originally planned for that most fascinating city of Athens, Greece, but 2020 being the year that it is, participants are all staying at home and practising their virtual presentation and networking skills. However, there is still plenty to see and learn about in the Poster and Demonstration, and Industry Track Sessions of the conference. We thank the ISWC General Chair, Lalana Kagal of MIT (Mass, USA) for her strong leadership of a conference that had to nd a new way of being the
i premier international research conference in Semantic Web, including knowledge graphs, linked data, ontologies, and AI on the Web.
We thank the conference sponsors: Metaphacts, IBM, inrupt, ebay, Coinform, accenture, SIRIUS, Oracle, Google, Springer LNCS, HEROS and the Arti cial Intelligence journal. We are also grateful to Easychair for its highly functional conference management toolkit, and to CEUR-WS for its high-quality, volunteer-operated service to the computer science research community.
The collection of papers in this proceedings were selected from those submitted to the Poster and Demonstration Track and the Industry Track of ISWC.
The Posters and Demos Track is one of the most vibrant parts of every ISWC. This year, the track was chaired by Rafael Goncalves and Kerry Taylor. We received a total of 97 submissions: 58 posters and 39 demos. The program committee, consisting of 87 members and the track chairs, accepted 43 posters and 35 demos based on 3 reviews per submission. The decisions were primarily based on relevance, originality, and clarity of the submissions.

The industry track provides an opportunity for industry adopters to highlight and share the key learnings and challenges of applying semantic web technologies in real-world and scalable implementations. This year, the track chairs Freddy Lecue and Jun Yan received 22 submissions from a wide range of companies of di erent sizes, and 15 submissions were accepted. The submissions were assessed in terms of the quantitative and qualitative value proposition provided; innovative aspects, impact, lessons learned, and business value in the application domain; and the degree to which semantic technologies are critical to their o ering. Each paper got one review from an Industry Semantic Web expert, which has been checked and validated by the Industry track chairs. The nal decision was based on the evidence and impact of industrial applications using and based on semantic web technologies.
