MWPD 2020 is the rst edition of the Semantic Web Challenge on Mining the Web of HTML-embedded Product Data, successfully collocated with the 19th International Semantic Web Conference (ISWC): https://ir-ischool-uos. github.io/mwpd. The purpose of this event is to promote research on mining product information on the Web, and the usage of structured data (e.g., HTML embedded data, microdata) in such tasks. The event organises two shared tasks: product matching and product classi cation, with benchmarking datasets and tools produced for reuse. This volume describes these tasks and participating systems in details, and includes one event overview paper, and six participant papers.
