PAPER Trust-based Service Recommendation in Social Network
http://onlinedatingsoundbarrier.blogspot.com.ar/2015/02/paper-trust-based-service.html
 
Please remember:
Behavioural recommender systems or other system that learns your preferences are useless for serious online dating purposes and Personality Based Recommender Systems are the next generation of recommender systems because they perform far better than Behavioural ones (past actions and pattern of personal preferences)
That is the only way to improve recommender systems, to include the personality traits of their users. They need to calculate personality similarity between users.

If you want to be first in the "personalization arena" == Personality Based Recommender Systems, you should understand HOW TO INNOVATE in the ............ Online Dating Industry first of all!

With valuations jumping so high, the USD1 billion club is getting easier and easier to get into. In 2014 alone, 38 different companies entered the USD1 billion club, according to a report from CB Insights. That is more than the three previous years, when only 22 companies made it combined.

The relations among the HEXACO model of personality, religiosity,

and subjective well-being in Iranian and Polish college students
http://www.sid.ir/fa/VEWSSID/J_pdf/75713930102.pdf

Academics had begun to publish Scientific Research using the HEXACO model of personality and they HAD discontinued the Big Five model (a.k.a. Big 5, OCEAN or FFI five factor inventory, FFM five factor model) soon. Online dating sites using the Big Five model could be considered obsolete sites, because the Big Five model has been proven as "an incorrect and incomplete model of personality"
------------------------------

eHarmony, is a 14+ years old obsolete site and a HOAX, based on a big scientific fraud, only sustained by big marketing budget.
The Big Five normative test had been proven/revealed as an incomplete and incorrect model to assess/measure personality of persons.
The Big Five normative test had been replaced by HEXACO or Big Six test.

ONLY ONE ROAD TO ACHIEVE INNOVATIONS  
The Online Dating Industry needs Innovations, but the innovations the Online Dating Industry needs will come from only one source: the latest discoveries in theories of romantic relationships development with commitment. 
Only 3 major discoveries can help to revolutionize the online dating industry.
I) Several studies showing contraceptive pills users make different mate choices, on average, compared to non-users. "Only short-term but not long-term partner preferences tend to vary with the menstrual cycle"
II) People often report partner preferences that are not compatible with their choices in real life. (FORGET Behavioural recommender systems  or other system that learns your preferences)
III) What is important in attracting people to one another may not be important in making couples happy. Compatibility is all about a high level on personality similarity between prospective mates for long term mating with commitment.

The Online Dating Industry does not need a 10% improvement, a 50% improvement or a 100% improvement. It does need "a 100 times better improvement", not 100% better, 100X better == a big INNOVATION.

The Online Dating Industry needs a very powerful algorithm like the "Teller Ulam design". In this case 100 times more powerful than actual matching algorithms.

Social dating is vaporware.
The Online Dating Industry does not need any improvement. It does need INNOVATIONS!

Online Dating for serious daters does not need to be more social, it needs to be more effective/efficient. It needs to reduce the false positives problem.

The key to long-lasting romance is STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests".

WorldWide, there are over 5,000 -five thousand- online dating sites
but no one is using the 16PF5 (or similar) to assess personality of its members!
but no one calculates similarity with a quantized pattern comparison method!
but no one can show Compatibility Distribution Curves to each and every of its members!
but no one is scientifically proven!

MORGAN STANLEY: There is no way lots of people start paying for Tinder
http://onlinedatingsoundbarrier.blogspot.com.ar/2015/02/morgan-stanley-there-is-no-way-lots-of.html
 

My bet: Nobody will pay.
How much money will you need to destroy Tinder forever launching an improved copycat of it? Like Facebook destroyed MySpace during 2009.
Less than USD100 million, but that is done, it is Bumble (backed by Badoo).
http://onlinedatingsoundbarrier.blogspot.com.ar/2015/01/valuing-tinder-like-vc-article-at.html

Have you seen the annual revenue of Match, Chemistry, OkCupid, Meetic, and other IAC's (nasdaq: IACI) online dating sites excluding Tinder? In the range of USD 800 Million with profits. The prospective revenue of Tinder is no more than USD 100 million because it will not outperform Badoo. As a social discovery site, Tinder, could make no profit at all, like Zoosk! (pending: ZSK)

"I read through the conference call. Lots of excuses and hand waving...they've already thrown in the towel on 2015 and are now trying to say 2016 will be the great year.
Tinder monetization testing is "solid" which is code for "much worse than we expected.""
