Wikimedia, Hello. I am pleased to share an exciting update regarding a proposal for a sister project, Wikifact - a resource for real-time collaborative fact-checking (https://meta.wikimedia.org/wiki/Wikifact). The update is available here: https://github.com/w3c/mathml/issues/390 . The gist of the new development is that end-users could select Web content in their browsers and then simply use context menus to invoke first-, second-, and third-party services. These services could include crowdsourced, wiki-based, services, e.g., Wikifact or some other new projects. When I first proposed Wikifact, in 2021, I was thinking that some markup-related or template-related solutions would be useful for providing end-users with user interfaces upon relevant portions of content (e.g., statements, claims, or facts) in documents. Today, I am thinking about end-users being able to select Web content and then use context menus to invoke first-, second-, and third-party services. These services might provide for end-users with proofs, arguments, justifications, or fact-checking-related information about the selected contents in new tabs. Today, I am also thinking about uses of Web Annotation technologies where end-users could toggle visualizing which content in Web documents already have proofs, arguments, justifications, or fact-checking-related information available for them. In summary, end-users will be able to select arbitrary contents from across the Web and use context menus to invoke services, e.g., Wikifact or some other new projects, to explore proofs, arguments, justifications, and fact-checking-related information pertaining to the selected contents. Thank you. I hope that these new developments are of some interest to you and that they might inspire you to continue to explore new uses of wiki technologies!
