IBM Deciphers Personality Types From 200 Tweets ?

Just read that post at Online Dating Insider and guess ...
Nothing new.

Profiling by music preferences, video preferences, color preferences, bookmarks preferences, handwriting analysis, purchases and buying trends from credit cards, facial features and other methods like them to assess personality add distortion to the measurement.

Moreover the HEXACO normative test is replacing the obsolete Big Five Model of personality.
“While the Big Five has been the dominant approach in personality research for over two decades, recent investigations have identified a sixth independent personality dimension referred to as Honesty-Humility (Ashton & Lee, 2007, 2009). ”

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 but there are different formulas to calculate similarity.

In case you did not notice, recommender systems are morphing to .......... compatibility matching engines, as the same used in the Online Dating Industry since years, with low success rates!!! because they mostly use the Big5 to assess personality and the Pearson correlation coefficient to calculate similarity.
Please remember: Personality traits are highly stable in persons over 25 years old to 45 years old.

Online Dating sites have very big databases, in the range of 20,000,000 (twenty million) profiles, so the BIG5 model or the HEXACO model are not enough for predictive purposes. That is why I suggest the 16PF5 test.

The only way to revolutionize the Online Dating Industry is using the 16PF5 normative personality test, available in different languages to assess personality of members, or a proprietary test with exactly the same traits of the 16PF5 and expressing compatibility with eight decimals (needs a quantized pattern comparison method, part of pattern recognition by cross-correlation, to calculate similarity between prospective mates.)
All other proposals are NOISE and perform as placebo.
e.g. eHarmony's algorithm is in the range of showing you 3 most compatible persons per 1,000 persons screened, and with the 16PF5 you can reach 3 most compatible persons per 100,000 persons screened; a 100 times more powerful algorithm (NOT 100% improvement, a 100 X improvement, really an innovation)

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!

What comes after the Social Networking wave?
The Next Big Investment Opportunity on the Internet will be .... Personalization!
Personality Based Recommender Systems and Strict Personality Based Compatibility Matching Engines for serious Online Dating with the normative 16PF5 personality test.
