CAS-TIL
Today’s ProblemIndividual End Users has little control over Web
InteractionProgrammers are in charge
• Web user interface and interaction flows are controlled by software programs deployed on the server
• These server side software programs are designed and implemented by software programmers
• Individual end user has no or very limited control over web interface nor interaction
CAS-TIL
Today’s ProblemWhat you see is what you get

Related Work
• Server Side Approach– User Categorization:
• Profile: user characteristics (e.g. roles, organization etc.)
• Behavior (e.g. Page-Ranking)References: A. Datta et al, M. Vazirgiannis, M. Eirinaki
– Portal• User customized content • E.g. iGoogle
Major Limitations:– Small degree of customization – Not on an individual level
CAS-TIL
Related Work
• Client Side Approach– Customized rendered web pages with browser
extension• GreaseMonkey• Chickenfeet
– Web Clipping
Major Limitations:– Customization on rendered content that
bears no correspondence to units of functionality from the server side

mySOA: It’s All About “ME”
Individual user:• chooses from units of functionalities • let the corresponding units of interaction artifacts and Flows be computed
Result: individualized web interaction experience
CAS-TIL
An SOA Enabled Alternative• Leverage the SOA model of a “Service” as units of
measure for server side functionality
• Build an abstract visualization finite state machine as the general model for web interaction with services
• Individual end user controls selection of units of server side functionalities using service interfaces as units of measure
• Corresponding individualized web interaction artifacts & flows are computed and generated by the client side plug-in
• This results in a truly individualized web interaction artifacts & flow that does not contain unwanted server side functionalities

Summary• SOA model of a “Service” as units of measure for server
side functionality
• Build an abstract visualization finite state machine as the general model for web interaction with services
• Individual end user controls selection of units of server side functionalities using service interfaces as units of measure
• Corresponding individualized web interaction artifacts & flows are computed and generated by the client side plug-in
• This results in a truly individualized web interaction artifacts & flow that does not contain unwanted server side functionalities
