Preface to the Proceedings of the 2023 International Semantic Web Conference Posters, Demos and Industry Tracks Irini Fundulaki Foundation for Research and Technology, Greece Kouji Kozaki Osaka Electro-Communication University, Japan Daniel Garijo Universidad Politécnica de Madrid José Manuel Gómez-Pérez Expert.ai Abstract This volume contains short papers presented at ISWC2023: 22nd International Semantic Web Conference November 06-10, 2023, held as an all in-person conference. We thank the ISWC General Chair, Juanzi Li of Tsinghua University, Beijing, China, for her leadership in organizing the conference. We also thank the conference sponsors, listed at https://iswc2023.semanticweb.org/sponsors/ for their generous support. We are also grateful to Easychair for its highly functional conference management toolkit and CEUR-WS for its high-quality, volunteer-operated service to the computer science research community. The collection of papers in these proceedings were selected from those submitted to the Poster and Demonstration Track and the Industry Track of ISWC. 1 Posters and Demonstrations The Posters and Demos Track was chaired by Irini Fundulaki and Kouji Kozaki. This track complements the paper tracks of the conference by offering an opportunity to present late-breaking research results, on-going projects, and speculative as well as innovative work in progress. The Posters and Demos Track encourages presenters and participants to submit papers that have the potential to create discussions about their work that provide valuable input for the future work of the presenters. At the same time, it offers participants an effective way to broaden their knowledge on a variety of research topics and to network with other researchers. This track received 101 papers for review, of which 57 were accepted (56% acceptance rate). Among the accepted papers, 28 were poster papers and 29 were demo papers. The program committee, consisting of 55 members and the track chairs, accepted the 101 contributions with an average of 5 reviews per submission. The 55 members of the PC were involved in a double-blind review process and assessed each submission based on a variety of criteria such as novelty, relevance to the Semantic Web, impact, technical contribution, and readability. Promising submissions requiring shepherding were guided by the track chairs to reach their full potential.
