With the start of Internet 3.0 (Semantic Web) we now know that the value of the online brand is not determined by clever advertising but by the users personal experience when interacting with the site. A good experience enhances your brand and a poor experience damages the brand.
So how do you ensure you provide a good experience every time.
This book starts well with realisation that users come to a site for a specific reason and need to carry out tasks-sets in order to complete their objective.
The book then focuses on context of the data using the idea of a multi-modal model which basically states that information needs to be delivered to people in different ways in order to be relevant. This has just become part of the W3C as a workgroup activity. (2/02)
After this the book covers some new technologies -ontologies and XML but fails to talk about P3P (trust) and RDF.
The book also fails to provide a tangible framework for putting in place a framework to measure task success/failure and thus make improvements to enhance the experience.
What is needed is an updated Balanced ScoreCard covering tasks with measurements specific for the web.
Lastly a new area of importance is the use of Behavioural Marketing which uses real-time monitoring of users online to track their behavioural mood - angry, lost, frustrated etc. This when linked to RDF, URI and Intelligent Agents (Semantic Web)will improve the web experience and truly make it 1:1 marketing.
