Center node: "semantify it a platform for creation publication and distribution of semantic annotations"
  Abstract: The application of semantic technologies to content on the web is, in many regards, as important as urgent. Search engines, chatbots, intelligent personal assistants and other technologies increasingly rely on content published as semantic structured data. Yet the process of creating this kind of data is still complicated and the necessity of it is widely unknown. The this http URL platform implements an approach to solve three of the most challenging question regarding the publication of structured semantic data, namely: a) what vocabulary to use, b) how to create annotation files and c) how to publish or integrate annotations within a website without programming. This paper presents the idea and the development of the this http URL platform. It demonstrates, that the creation process of semantically annotated data must not be hard, shows use cases and pilot users of the created software and presents where the development of this platform or alike projects could go to in the future.
