It is a truth universally acknowledged that a single man on a dating app will pursue a date with a single word: "hey." And according to a new study, that may be the best strategy for attracting a partner who is out of your league. Elizabeth Bruch and Mark Newman at the University of Michigan, US, studied the messaging patterns of 94,478 men and 92,457 women on a free online dating website. The users were located in New York, Boston, Chicago and Seattle, all were seeking heterosexual relationships, and their genders were self-identified. They found that women receive more messages than men, and most of the messages sent on the service go to only a small fraction of users.

Most Compatible -- attempts to use all your cumulative data to find the perfect match for you. The company's been testing this feature, which occasionally recommends a possible match to users, for at least month now. Those recommendations were only offered once a week during testing but will now come every day. Justin McLeod, Hinge's CEO, tells me the company spent the testing time honing its backend algorithm and getting Most Compatible to a point where the company feels confident putting it fully out there. Most Compatible, he says, uses machine learning to figure out each user's taste.

Artificial intelligence helps create your own personal assistant in the job search. Have you ever wished you had a personal assistant to help you find a new job or move up in your career? Well, now you can have one, thanks to the chatbot. Chatbots know how to interact with people, because they either follow a human-composed set of rules or learn how to communicate via artificial intelligence (AI) technologies. Bots that follow rules are more limited and can only answer things they've been programmed to understand.

At lunch last week, I learned that a couple colleagues were engaged in a little duel--trying to out-walk each other, as tracked by their new Fitbits. Self-improvement was definitely the goal, but seeing peer performance and benchmarks provided the required motivation to achieve that goal.

Recruiting has become the digital equivalent of looking for an elusive needle in a very, very large haystack. Artificial intelligence (AI) is fast becoming an invaluable tool for recruiters and hiring managers in sifting through that haystack, scouring applicant pools and matching the right talent to the right jobs. Consider the Palo Alto–based startup Connectifier, which is used by companies like PayPal and Netflix. It aggregates publicly available information about potential job candidates--think professional networking profiles and social media interactions--and gathers the data in its own search index. The company's AI algorithm then creates personal profiles of candidates and extracts insights about whether they would be a good match for a job, even if they're not actively searching for a new one.
