Open Semantic Framework is a tool that helps computers better interpret and understand data from the web. It does this by breaking up webpages and documents into different parts (called 'semantic units'), which can then be easily understood by computers. This makes it easier for computers to interpret data and make sense of the information they find. For example, if someone were looking up information on a certain topic, the computer could use the Open Semantic Framework to break up the document into its different parts, so it can interpret and understand the data more easily.
