I think I have had slightly better results than average because I am using ABMs that learn and have social media as precepts. There is a "training" period for each agent where it is trained based on LinkedIn data etc... but I 100% agree with you, I am also interested to see how it works; currently I have not tested more than 100 at a time.
I worry that you may be underestimating the competition. bondadapt.com are a prime example. Recruitment companies pay seven figures annually for their system and they've invested an insane amount of time and money into improving their NLP system and, speaking as someone who's used it extensively in the past, its results are relatively poor when you are dealing with a database of tens of thousands of resumes.
Please don't get me wrong, I'd love to see you crack it and if you manage it be sure to share the results!
