Given you just mentioned semantic search (a term I haven’t heard in over 15 years) and the other breadcrumbs in this comment, you wouldn’t by chance be an English lecturer living in Ireland would you?
me? No. Ex trainee neruopsychologist and failed academic who was in the right place at the right time back in the mid 90s who didn't pick up computers for professional interest until the mid-late 2000s after getting excited by Neil Stephenson's Cryptonomicon when I was looking for a career change. These days I identify as an international computer hacker, but mainly to take the piss (due to the tiny element of truth sitting underneath)
