PAPER Measuring similarity between user profile and library book

PAPER Measuring similarity between user profile and library book.

In the development of recommender system either the content or collaborative filtering is necessary. To filter the records it is required to measure the similarity between profile of user and items present in the dataset. This experiment is performed on the dataset containing 978 books related to computer science field and 7 users. Similarity between profile of user and contents of book is measured using Euclidean, Manhattan, Minkowski, Cosine distances. The results are evaluated and compared. This work is useful in the development of library recommender system.
--------------------------------------
 Please remember:
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)
http://onlinedatingsoundbarrier.blogspot.com.ar/2014/11/paper-investigation-and-application-of.html
http://onlinedatingsoundbarrier.blogspot.com.ar/2014/03/new-papers-recommender-systems.html

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. 
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The BIG 5 (Big Five) normative personality test is obsolete.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".

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

Please see: "How to calculate personality similarity between users"
Short answer: the key is the ENSEMBLE!
(the whole set of different valid possibilities)
http://onlinedatingsoundbarrier.blogspot.com.ar/2013/03/how-to-calculate-personality-similarity.html
Worldwide there are over 5,000 online dating sites, no one uses the 16PF5, 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.

Uber raising funding at a USD40 billion valuation?

Astonished.
http://vator.tv/news/2014-11-26-uber-raising-funding-at-a-40-billion-valuation

"Earlier this month, it was reported that Uber would be raising another USD1 billion in funding at a possible USD25 billion valuation. After the scandalous week that the company just had, though, some may have questioned how investors would react. After VP Emil Michael suggested that the company should devote USD1 million to dig up dirt on the personal lives and families of journalists who say mean things about the company, would they balk at putting their money in?
Nope. Not at all. In fact, they are going full steam ahead."

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.)

PAPER Investigation and application of Personalizing Recommender Systems ....

www.ijana.in/papers/V6I2-2.pdf
 Investigation and application of Personalizing Recommender Systems based on ALIDATA DISCOVERY 

abstract:
To aid in the decision-making process, recommender systems use the available data on the items themselves.
Personalized recommender systems subsequently use this input data, and convert it to an output in the form of ordered lists or scores of items in which a user might be interested. These lists or scores are the final result the user will be presented with, and their goal is to assist the user in the decision-making process. The application of recommender systems outlined was just a small introduction to the possibilities of the extension. Recommender systems became essential in an information- and decision-overloaded world. They changed the way users make decisions, and helped their creators to increase revenue at the same time.

eHarmony is a 14+ years old obsolete site using Big Five traits to measure personality of its members, but the Big Five normative test that 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.
Online Dating sites OFFERING COMPATIBILITY MATCHING METHODS BASED ON PERSONALITY SIMILARITY 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 16PF5 test instead.

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)

Lack Of Innovation & Decadence can summarize the Online Dating Industry for years.
The Online Dating Industry is performing like the Pharmaceutical and Cosmetic Industry before the USA Food and Drug Administration was created. There is no/weak Legislation, no ID verification, low reliable background checks, no Quality Norms.
No one compatibility matching method is Scientifically Proven.
The entire Online Dating Industry for serious daters in 1st World Countries is a HOAX, performing as a Big Online Casino, with a low effectiveness/efficiency level of their matching algorithms (less than 10%). In the same range as searching by your own.

I live in a South American country and I am really astonished to see how online daters in "1st World" countries are really victims of human experimentation. No actual online dating site  is "scientifically proven" because no one can prove its matching algorithm can match prospective partners who will have more stable and satisfying relationships -and very low divorce rates- than couples matched by chance, astrological destiny, personal preferences, searching on one's own, or other technique as the control group in a peer reviewed Scientific Paper for the majority (over 90%) of its members.  The key to long-lasting romance is STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests".

PAPER: RecLand: A Recommender System for Social Networks

http://dl.acm.org/citation.cfm?id=2661850
Social networks have become an important information source. Due to their unprecedented success, these systems have to face an exponentially increasing amount of user generated content. As a consequence, finding relevant users or data matching specific interests is a challenging. We present RecLand, a recommender system that takes advantage of the social graph topology and of the existing contextual information to recommend users. The graphical interface of RecLand shows recommendations that match the topical interests of users and allows to tune the parameters to adapt the recommendations to their needs.


Please remember:
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)

MEETME Q3 2014 Financial Highlights

via SeekingAlpha
http://seekingalpha.com/pr/11595895-meetme-reports-third-quarter-2014-financial-results?app=n

• Total revenue was USD11.6 million, up 15% from the third quarter of 2013.
• Mobile revenue was USD6.7 million, up 128% from the third quarter of 2013.
• Mobile revenue represented 58% of total revenue, the highest in MeetMes history.
• Mobile average revenue per user (ARPU) was USD2.29, up 108% from USD1.10 in the third quarter of 2013, and exceeded web ARPU of USD1.01 for the fourth consecutive quarter.
• Mobile average revenue per daily active user (ARPDAU) was USD0.082, up 105% from USD0.040 in the third quarter of 2013. 

As a said before "you can change the name "MeetMe" for Tinder, Badoo, Zoosk, Skout, AreYouInterested (AYI), HowAboutWe, Twoo, Twine, Hinge, LikeBright, even MySpace and others to make the same analysis. ... but my bet is: all social dating / social discovery sites are vaporware."

Tinder tried to be the next .... Facebook (Forbes saga).

Tinder offers "social discovery, gamification, location and messaging features."

Those Tinder's founders were/are only puppets from IAC's Match Group.
My bet: IAC will put Tinder to sleep soon or later.
Facebook allows minors to use it (people from 13 to 17 years old)
Online Dating is NOT for minors.
http://onlinedatingsoundbarrier.blogspot.com.ar/2014/08/how-tinder-will-collapse.html
The IAC is not going to conduct Identity Verification to screen all Tinder's members.
It seems Tinder is like Chatroulette but it will collapse like Skout.
http://mashable.com/2012/06/13/skout-rape/
When the IAC Personals bought OKCupid (3+ years ago) for an astronomical amount of money, the OKCupid team had the task to copycat Badoo, but they failed in that mission. IAC Personals backed Tinder instead, as the copycat of Badoo. Tinder is only a cheap marketing tool to send prospective clients to Match and make them paid there, but it seems there is a divorce between Tinder and Match just now!
(Tinder cannibalizing Match)
Perhaps the IAC will "discretely bury" Tinder soon, it will absorb it and merge with Match mobile (with Stream and Mixer features) as soon as possible.

Worldwide there are less than 7 million paid members (adding up all the ones at eHarmony/eDarling/EliteSingles, Match, Chemistry, Meetic, MeeticAffinity, OkCupid, PeopleMedia's Communities, PlentyOfFish, Parship/eCift, and others).
They do not want to innovate. They want to squeeze their big databases to get all the juice (money) from the wallets of the daters.

Do you remember Chatroulette? Lots of persons want to use it, but nobody wants to pay for it.
It seems Tinder is like Chatroulette but it will collapse like Skout (problems with minors using it). Please see this information from Alexa and Compete, they show their sites reached operating ceiling!
