Dr. Nunes and Dr. Hu are going to talk at ACM Recommender Systems 2012
Tutorial 2: Personality-based Recommender Systems: An Overview and Dr. Graepel is also going to give the session Towards Personality-Based Personalization
------------------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.
Have you seen as Personality Based Recommender Systems need to calculate personality similarity between users, they really are compatibility matching engines like the ones used in the Online Dating Industry?
They mostly use the Big5 to assess personality and the Pearson correlation coefficient to calculate similarity.
WorldWide, there are over 5,000 -five thousand- online dating sites
but no one is using the 16PF5 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!
In compatibility matching methods there are 2 steps:
1) to objectively measure personality traits or other human variables (with the 16PF5 test).
2) to calculate compatibility (similarity) between prospective mates.
Three words with different meanings for different persons or companies: Compatibility / Personality / Similarity
Sometimes the word compatibility means a high degree of similarity between several variables (religion, education, income, personality, likes and dislikes, etc.) of prospective mates; sometimes compatibility means a mix of similarity and complementarity between variables; sometimes when a dating site says compatibility or even chemistry, nobody really knows exactly what it means!
Some online dating sites offering compatibility matching methods use the word similarity as: "a proprietary Dyadic Adjustment Scale", others mean: "a proprietary multivariate linear regression equation", some say a mix of similarity and complementarity meaning: "a proprietary multivariate logistic regression equation", still others mix similarity and complementarity meaning: "a proprietary equation to calculate compatibility between prospective mates!"
Personality could be assessed by different methods.
No actual online dating site offering compatibility matching methods uses the 16PF5 normative test available in different languages, the 5th version actualized after Census 2000.
