Personalization - An overview
What is Personalization? Personalization is the process of tailoring content to individual users' characteristics or preferences. It is a means of meeting the customer's needs more effectively and efficiently, making interactions faster and easier and, consequently, increasing customer satisfaction and retention.

Personalization - An overview
Web personalization is delivering different and unique content to each individual customer based on the customer's interests. It's your own version of the web site, a site just for you.
The real benefit of personalization occurs when an individual has an "aha!" experience that occurs when the content adapts itself based on the person's profile, and provides something new, different, and possibly unexpected.

Personalization vs Customization Customization Personalization You explicitly specify what you want. It gives explicit user control ( you are what you say you are ) E.g. choosing which information elements might be presented on a home page, choosing display colors, etc. Customization is at a generic "feature" level , where you see/hide etc what you want My Yahoo is an example of customization where you tell the site what you want Personalization uses implicit interests and learns what you like from your actions ( you are what you click on and what you buy ) E.g. getting the information related to one’s preferences and regular activities Personalization is at the data/ content served level Amazon.com is an example of personalization where the latter learns your interests and adapts to your needs

A sample scenario depicting the ultimate goal of personalization. The holy grail of e-commerce is always to achieve a real world experience , online. Something like …
Sales Person: "Hi, how may I help you?“
Customer: "I'm looking for a new digital camera.“
Sales Person: "Great, did you have a model in mind?“
Customer: "Uh, no, I'm not sure which model I need. I was hoping you could help me.“
Sales Person: "Great! Well, let me ask you a few questions ...“
Personalization aims at creating such (like the above conversation) a compelling and strong user experience in on the web by anticipating the user’s needs i.e. the questions the customer is most likely to ask.

Types of Personalization
There are three types of Personalization:
Simple filtering
A site displays content based on predefined groups of site visitors .
Rules engines
In a rules based system, the site owner defines a set of business rules which determine what category of content is shown when a certain profile type visits the site.
Collaborative filtering The preferences of the community of people with similar characteristics are used to predict appropriate content.
Decision Content 1 Content 2 Content 3 Content 1 Content 2 Content 3 User Users with similar preferences Recommended Content Similar preferences

Fill-in Profile/ forms: The user has to do lot of work filling complex questionnaires, which repels them.
Click-stream Analysis/ Web Usage Mining: It does group profiling, but privacy issues remain.
Cookies: ‘Tag’ / identify the user and his browser, but security issues remain with cookies.
Measure directly by asking the user to rate products .
Collaborative Filtering: It is fast emerging as best practice for personalization as it doesn’t have the above drawbacks.
Approaches to gather user data & Best practices

Collaborative Filtering – A Best Practice
In Collaborative Filtering, choice of content is based on the assumption that this particular user will value that which the like-minded people also enjoyed . The preferences of the community of like-minded people are used to predict appropriate content.
The user’s tastes are either inferred from their previous actions (for example buying a book, or viewing a product is assumed to show an interest (or taste) for that product).
This method has an advantage of speed and efficiency in computation, thus delivering rapid feedback. The reliance on a ‘critical mass’ of users can be a problem for collaborative filtering.
Recommendation systems use collaborative algorithms (they are the programs which attempt to predict items like movies, music, books, news and web pages that a user may be interested in, given some information about the user's profile).

How personalization software can help ?
Personalization software contain a dynamic recommendation system based on collaborative filtering. E.g. IBM Like Minds is software that could be used with any e-commerce application. It analyze user interactions that occur on websites and generate real time predictions and recommendations for users.
For example, the following types of transactions may be recorded:
Products a user has purchased
Items added or removed from a shopping basket
A history of the user's navigation throughout the application
Products that go best with a product that the user has already selected
Any action or series of actions that are meaningful for a site

Domains where we can use personalization software
The personalization software could be used in a variety of situations:
e-Retailer promotion and personalization web sites
Financial portal content recommendation and personalization web sites
Help desk or on-line technical support content recommendation web sites
Gift recommendations for e-Retailer
Music, movie, book , or other product rating and recommendations
Travel - trip planners

Computer , Don’t 2 nd guess me !
“ Don't stereotype me - just give me the options because I prefer choosing for myself rather than having the computer tell me what's good for me”
What users want on one visit may be very different from what they want on the next.
Don’t ignore basic design & User Experience
Web personalization is much over-rated and mainly used as a poor excuse for not designing a navigable website.
There is no substitute for good design, usability engineering and proper information structure.
Is Personalization needed? Where will it not work?

Privacy / ethical issues?
Consumers are clearly expressing an interest in a personalized experience. But at the same time, they are expressing significant fear about security of their personal information.
“ Should I share my likes & dislikes with anyone for a more personalized online experience?”
Paradox of the active user
Users never want to waste time teaching/training the system about themselves by filling complex forms, questionnaires. They want to do, explore and want results, right away.
Good personalization requires the system to know a lot about the user. This is in direct conflict with the paradox of the active user.
Is Personalization needed? Where will it not work?
