I'm trying to define a metric between job titles in IT field. For this I need some metric between words of job titles that are not appearing together in the same job title, e.g. metric between the words
senior, primary, lead, head, vp, director, stuff, principal, chief,
or the words
analyst, expert, modeler, researcher, scientist, developer, engineer, architect.
How can I get all such possible words with their distance ?
