Vernon Fowler"In October last year, Netflix launched an unusual contest. The online movie rental company is offering 1 million dollars to anyone who can improve their recommendation engine by 10%. Netflix is known for its innovation and bold moves and in the grand scheme of things, $1M is not a lot of money for such a business."

A good recommendation engine can make a difference not just for Netflix, but for any online business. This is because there are two fundamental activities online - Search and Browse. When a consumer knows exactly what she is looking for, she searches for it. But when she is not looking for anything specific, she browses. It is the browsing that holds the golden opportunity for a recommendation system, because the user is not focused on finding a specific thing - she is open to suggestions.
-
The main approaches fall into the following categories:
-
- Personalized recommendation - recommend things based on the individual's past behavior
- Social recommendation - recommend things based on the past behavior of similar users
- Item recommendation - recommend things based on the thing itself
- A combination of the three approaches above

The Amazon system is phenomenal. It is a genius of collaborative shopping and automation that might not be possible to replicate. This system took a decade for Amazon to build and perfect. It relies on a massive database of items and collective behavior that also "remembers" what you've done years and minutes ago. How can new companies compete with that?
Surprisingly, there is a way. The answer is found in a subject that has little to do with online shopping - genetics.
-
The Music Genome Project was launched to decompose music into its basic genetic ingredients. The idea behind it is that we like music because of its attributes - and so why not design a music recommendation system that leverages the similarities between pieces of music.
-
Pandora became a hit because of its precision and low cost of entry. The user just needs to pick one artist, or a song, to create a station that instantly plays similar music.
-
Pandora does need the user's tastes or memory, it has its own - based on music DNA.

Recommendation engines are important pieces of online commerce systems and their user experience. Retailers have a big incentive to provide recommendations to those users who are "just browsing", to drive them towards a transaction. Amazon.com, the leader in the space, has a very compelling personalization offering. The problem that other retailers face is lack of user information and infrastructure.
Recent approaches to recommendation engines, like the genetics-inspired Pandora and social tagging pioneered by del.icio.us, are intriguing. These approaches hold the promise to provide instant gratification, without asking the user to reveal her preferences and past history. Regardless of how things unfold in the future, Amazon, Pandora and del.icio.us are examples of extraordinary recommendation technologies. We commend them and are watching in fascination for what is coming next. -

During browsing, the user's attention (and their money) is up for grabs. By showing the user something compelling, a web site maximizes the likelihood of a transaction. So if a web site can increase the chances of giving users good recommendations, it makes more money. Obviously this is a difficult problem, but the incentive to solve it is very big. The main approaches fall into the following categories:
-
The section above shows Social recommendations. Notice that it is very analytical, giving me a statistical reason for why I should buy this item. Also note that this recommendation is also a Personalized recommendation, since it is based on an item that I clicked recently.
-
The section above shows Item recommendation based on New Releases. Clicking on the Why is this recommended for you? link takes me to a view of my purchasing history. So this recommendation is also a Personalized recommendation, since it is based on my past behavior.

The Music Genome Project
was launched to decompose music into its basic genetic ingredients. The idea behind it is that we like music because of its attributes - and so why not design a music recommendation system that leverages the similarities between pieces of music. -
Pandora does need the user's tastes or memory, it has its own - based on music DNA. Sure, sometimes it might not be perfect, as the user's taste might not be perfectly addressed. But it is rarely wrong.
-
In the past few years we have been doing this a lot online. It's called tagging!
-
Pandora had a big startup cost, because thousands of pieces of music had to be manually annotated.
-
So the del.icio.us approach holds intriguing possibilities of self-organizing classification and recommendation systems. With enough users and more tweaking, social tagging can result in a system that works equally well for books, wine and music. Provided, of course, that tags are so good that they become genes!
-
Retailers have a big incentive to provide recommendations to those users who are "just browsing", to drive them towards a transaction.

Regardless of how things unfold in the future, Amazon, Pandora and del.icio.us are examples of extraordinary recommendation technologies.

-
I don't think it's necessarily the case that users who know what they want search while others browse. In my experience there's substantial spill in both directions and the choice of search v. browse has more to do with behavioral preferences and confidence in the underlying search engine than anything else.
Vistors to e-commerce sites are always open to suggestion/education, hence any up-sell/cross-sell strategies that leverage recommendation should address searchers and browsers, and a good UI should offer both avenues on every web page.
-
Netflix, like Amazon, has figured out that helping people make choices is the key to market success.
-
People won’t buy things if they can’t make fundamental choices, and most people won’t make as many choices if they don’t get a little help -- without being barraged with too many questions.
-
That’s the trick. We don’t want to answer too many questions about what we’re looking for. Half the time we don’t know what we’re looking for (“just browsing�?) and the other half of the time we are incapable of describing it – or maybe that’s just me. Harvard professor Daniel Gilbert details people’s inability to understand or describe what makes them happy in his book, “Stumbling on Happiness�?. We think that many of those same mental barriers exist for people shopping or searching online, and we believe a good recommendation platform is essential to overcome them.
-
Recommendation and personalization technology that works across all three screens (your computer, mobile devices and perhaps most importantly your television) will become increasingly necessary as the long-tail of content expands beyond the web and into your living room.
-
ChoiceStream’s RealRelevance is the only personalization system of its kind to profile both people and content. ChoiceStream automatically classifies all types of content—music, movies, TV shows, games—based on its various characteristics, otherwise known as attributes. ChoiceStream then learns from these attributes and each consumer’s interaction with the content to better understand the consumer’s unique tastes and preferences. ChoiceStream’s patent-pending personalization, Attributed Bayesian Choice Modeling, enables ChoiceStream to learn about a consumer quickly and accurately, avoiding out-in-left-field results that can immediately undermine consumers’ faith in the recommendations they’re receiving.
-
DirecTV recently implemented an online personalized My TV Planner using ChoiceStream’s technology to recommend programming of interest to its 15.5 million viewers. Although these recommendations are currently only available online, this is likely the first step in the migration to the set-top box. Recommendation engines may very well be the answer to maximizing the television experience; just as search engines have been the answer for the Internet.
-
Search engine algorithms are based on text, information, and links. This philosophy doesn’t necessarily produce the best results in a television environment. Television viewers don’t want to search for programming in an empty box. They want relevant choices provided without having to search. Therefore the idea of pushing programming at viewers based on their previous choices and individual tastes is being adopted.
-
The key to pushing this relevant programming is the development of a rich classification system for the programming itself. To do that, cable and satellite leaders are enlisting the help of innovative technology vendors to build characteristic indexes around programming and movies available to users. This index contains more than the kind of information a search engine would utilize. For example, when implemented into an on-demand movie service, the index contains certain attributes of each movie. Is the movie thought provoking? Action packed? Satirical?
-
A viewer may not truly understand the reasons why they chose “The Breakup�? and were subsequently recommended “Thank Your for Smoking.�? The correlation between a romantic comedy and a satire isn’t necessarily obvious to the naked eye. However, the personalization technology can easily dig deeper into these movies attributes and determine that in fact there is a correlation between the two choices. In this case, both films take objective looks at dramatic conflict and although vastly different both leave viewers examining failed relationships. Some may argue that in this sense cable and satellite providers may know you, or at least your choices, better than yourself.
-
Advertisers are using personalization – preference-driven targeting – to help captivate these unleashed consumers, winning their attention with messages that are directly relevant to their needs and interests. Ensuring a more relevant, more rewarding advertising experience is a first step toward building loyalty between the consumer and advertiser.
-
Good post. There is another type of recommendation that I like and that you didn't mention, at least not explicitly - People Recommendations.
-
If you click through some of those people, you will see what we have in common: we're all technical, java seems to be a predominant PL, and we are all interested in search, information retrieval, information gathering, etc.
-
Another interesting people recommendation at Simpy can be found integrated in bookmark search results. For example, here is a search for adaptiveblue. Note the "Related Users" on the right. You are searching for AdaptiveBlue? Well, then these users might be of interest to you.
-
Recommendation integration is slowly happening in lots of places and will eventually be integrated into these options or become the 3rd fundamental activity.
-
Item-to-item is the Amazon-style 'people who bought X also bought Y'. Item-to-item recommendations are often based (for popular products) on basket pairings (when I search for books on development methodologies, I often buy two or more of them at a time, so they are paired in my shopping basket and also in Amazon's database), which are more accurate than lifetime user pairings (I also do my Christmas shopping on Amazon, and buy pop-up books for my niece).
-
The problem with person-to-person recommendations is that each individual had to rate a lot of things before a suitable 'recommender' could be found. The upside to person-to-person recommendations is that, once a suitable recommender (or group of recommenders) is found, the recommendations are deep and span broad categories.
-
I agree that Amazon knows as much about recommendations as anybody; but the accuracy of recommendations comes from their large dataset, not necessarily from the sophistication of their methods.
-
Note that Amazon does not use a 'genome-oriented' classification to find out why one product is bought alongside another--they could never scale that without an open source effort.
