about article: "Big Data Becomes Big Business for Some Online Dating Sites"
https://onlinedatingsoundbarrier.blogspot.com/2019/02/about-article-big-data-becomes-big.html

The Big Five (Big5) normative personality test is the biggest mistake Psychologists made since several years ago. The Big Five is also known as the Five Factor Model theory of personality traits, a psychological model based on research by Paul Costa and Robert McCrae.    
As some of the subdomains of the main domains of the HEXACO model are different from the subdomains of the main domains of the Big Five model, it can not be simple added the scale of the Honesty-Humility factor to the Big Five model to upgrade the personality test to the HEXACO model.".. the Big Five's Agreeableness and HEXACO's Agreeableness are not identical. The Big Five factors do not include an Honesty-Humility factor, but some of the characteristics belonging to Honesty-Humility are incorporated into the Big Five's Agreeableness factor. Although earlier investigations found only the Big Five factors, more recent studies conducted in various languages (including English) with larger sets of adjectives recovered six factors. "
 
I need to hammer your head and drill holes in your brain to make you understand Online Dating sites have very big databases, in the range of 20,000,000 (twenty million) profiles, so the Big Five model or the HEXACO model are not enough for predictive purposes. That is why I suggest the 16PF6 test instead and another method to calculate similarity.
Also take into account women under hormonal treatment because several studies showed 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". 
 
Please remember: Personality traits are highly stable in persons over 25 years old to 45 years old (the group of persons who could be most interested in serious online dating) They have only minor changes in personality (less than 1 interval in a normative test) and the 16PF6 test will not "see" them because the output of the 16PF6 test are 16 variables STens (Standard Tens) taking integer values from 1 to 10. STens divide the score scale into ten units. STens have the advantage that they enable results to be thought of in terms of bands of scores, rather than absolute raw scores. These bands are narrow enough to distinguish statistically significant differences between candidates, but wide enough not to over emphasize minor differences between candidates.

AGAIN the obsolete Big Five normative test.

The one or your soulmate or the perfect match does not exist!
It will only exist a pool of compatible persons, not more than that.
No online dating site can promise you to find "the one" or "your soulmate" or a "perfect match".
Moreover the person you are looking for does not exist or if it exist, he/she does not want to meet you because your are not compatible.

What is important in attracting people to one another may not be important in making couples happy. The key to long-lasting romance: COMPATIBILITY is exactly STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests or political views".

PAPER: Age trends in HEXACO-PI-R self-reports

http://www.sciencedirect.com/science/article/pii/S0092656616301040
Journal of Research in Personality Volume 64, October 2016, Pages 102–111
Highlights

•     We examined age differences in HEXACO personality self-reports (N ≈ 100,000, ages 14–74).
•     Honesty-Humility showed an upward trend of about 1 standard deviation between ages 18 and 60.
•     Age trends for other dimensions often differed by facet.

We examined age differences in the six broad HEXACO personality factors and their defining facets, using self-reports from an online sample (N ≈ 100,000, ages 14–74). Honesty-Humility showed an upward trend of about one full standard deviation unit between ages 18 and 60. Age trends for Emotionality and Extraversion differed by facet, but overall were downward for Emotionality and upward for Extraversion. Agreeableness showed relatively weak age trends. Conscientiousness and Openness showed upward age trends during the teen years (extending to the mid-20s for Conscientiousness), but age trends thereafter differed considerably by facet. Results are discussed in relation to previous findings for the Big Five, to the “age-crime curve”, and to possible evolved developmental origins.

Brief Report: Cross-sectional age differences in the HEXACO personality: Results from a Japanese sample.

http://www.sciencedirect.com/science/article/pii/S0092656616300125

Highlights

•The present study investigated age differences in personality in Japanese adults.
•The level of Emotionality was negatively associated with age.
•The level of Honesty–Humility was positively associated with age.
•Extraversion, Agreeableness, Conscientiousness, and Openness were not associated with the participant age.

Abstract

Little research has been conducted on personality development in non-Western countries. The present study investigated age differences in personality in Japanese middle adults (N = 2000; M = 40.94 years; SD = 5.35, range 30–49; 1000 women). After controlling for educational level, annual income, marital status, and gender, it was found that the level of Emotionality was negatively associated with age. Honesty–Humility, on the other hand, was positively associated with age. However, Extraversion, Agreeableness, Conscientiousness, and Openness were not associated with the participant age. These findings suggest that trends in personality development may differ slightly between Western and non-Western countries.

PAPER: The personality systems framework: Current theory and development

http://www.sciencedirect.com/science/article/pii/S0092656614001214?

"Highlights
• Most personality psychologists are systems theorists and draw on general systems theory.
• The personality systems framework covers: (a) personality’s definition, (b) its parts, (c) organization, (d) development.
• I illustrate the four topics of the framework by drawing on examples from the theory of personal intelligence.
• The personality systems framework draws lightly on theories from the field to enhance its depiction of personality.
• The personality systems framework describes the discipline and provides formal models of personality."

-----------------------------------------------------

Similarity is a word that has different meanings for different persons or companies, it exactly depends on how mathematically is defined. In case you had not noticed, recommender systems are morphing to .......... compatibility matching engines, as the same used in the Online Dating Industry since years, with low success rates until now because they mostly use the BIG 5 to assess personality and the Pearson correlation coefficient to calculate similarity.
The BIG 5 (Big Five) normative personality test is obsolete. The HEXACO (a.k.a. Big Six) is another oversimplification. Online Dating sites have very big databases, in the range of 20,000,000 (twenty million) profiles, so the BIG 5 model or the HEXACO model are not enough for predictive purposes. That is why I suggest the 16PF5 test instead and another method to calculate similarity. I calculate similarity in personality patterns with (a proprietary) pattern recognition by correlation method. It takes into account the score and the trend to score of any pattern. Also it takes into account women under hormonal treatment because several studies showed 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".
http://onlinedatingsoundbarrier.blogspot.com.ar/2014/12/paper-collaborative-filtering-for.html
If you want to be first in the "personalization arena" == Personality Based Recommender Systems, you should understand the ............ Online Dating Industry first of all!

Worldwide there are over 5,000 online dating sites, no one uses the 16PF petsonality test, no one is scientifically proven yet, and no one can show you compatibility distribution curves, i.e. if you are a man seeking women, to show how compatible you are with a 20,000,000 women database, and to select a bunch of 100 women from 20,000,000 women database.
