Personalization
Personalization is the process of tailoring pages to individual users’ characteristics or preferences that will be meaningful to their goals.
However, it is not always easy for the designer to foresee the distinct utilization contexts and goals from where the application is accessed.
O. Díaz, S. Pérez & I. Paz 4
Personalization: a do-it-yourself approach
Traditional approaches: • “everything for the people, nothing by the
people”• difficult to foresee all circumstances
Do-it-yourself approach: • end users add their own content • …once the application is already deployed
O. Díaz, S. Pérez & I. Paz 5
Mashup approach
Mashups allow the user to combine existing data from disparate sources in innovative ways.
http://fr.local.yahoo.comA MASHUP
is the resource to be capitalized on
O. Díaz, S. Pérez & I. Paz 6
Mashup approach
But frequently,… • you are gathering data not just for the sake of
the data itself • but to help you to make some decisions.
O. Díaz, S. Pérez & I. Paz 7
Mashup approach
An example
A MASHUP

An application
Another application
it would be most convenient to post the mashup data by the application where the
decision is taken.
O. Díaz, S. Pérez & I. Paz 8
Mashup personalization
Process whereby • recurrent users
– It is not useful for sporadic users
• can enrich – no replacement nor deletions
• existing applications– no new applications
• with additional data using a mashup approach – taking data from elsewhere

Yahoo! Pipes
(1) Drag modules from the panel on the leftand drop them in the main panel.
(2) Fill the required modules’ fields
(3) Connect modules between them

Website: • Any existing web application
Mashup• A Yahoo! pipe
MARGMASH is the “+”

Navigation
Lets the user to navigate to the page where a mashup needs to be posted.
Which are the pages where the end user would
like to post pipes?
O. Díaz, S. Pérez & I. Paz 17
Page Classification
Page classification helps distinguish between pages on applications
How can these pages be identified?
O. Díaz, S. Pérez & I. Paz 18
Page Classification
Search
Results
Info.
A page class is defined as the set of pages that describe the same type of information and have a similar page structure
O. Díaz, S. Pérez & I. Paz 19
Page Classification
the user annotates the page by selecting some HTML elements.
is identified through an absolute XPath over the DOM tree.
Notice that, we are abstracting from a page-instance-based input selection to a page-class-level identification of the distinct elements on the page.
O. Díaz, S. Pérez & I. Paz 20
Mashup Anchors
Where does the user wantthe pipes to be located?
Mashup anchors play a double role. • they hint for placing the mashup output. • they provide some feed data for the associated mashup
O. Díaz, S. Pérez & I. Paz 21
Pipe Assignment
Which pipes does the userwant to be posted to a
certain anchor?
pipes’ identifiers
pipes’ output layout
pipes’ navigation mode
O. Díaz, S. Pérez & I. Paz 22
Mapping Pipe Inputs
From where does the userextract the data that feed
the pipes’ input?
pipes’ starting feeds

Conclusions
Margmash: website + mashup
The mashup is contextualized • by delivering it within an existing website
The website acts as • the initial data provider for the mashup input
parameters • as well as the container for its output
