OT: I was using Wikipedia the other day and it occurred to me how primitive it is to have all the inner links to other Wikipedia articles defined manually, surely these should have been automated by now (i.e., marking a word or two would link you to the relevant article).
The disambiguation could be challenging. (Does "The Sun" link to our closest star or the tabloid in the UK.) It would be a fun project to try and determine the correct link based on the context.
It would take some AI to work it out, unless using the context around the link. "Sun" could refer to many things, its not really possible for wikipedia to know which one you're on about. So links are still done manually.
