SWI evaluations methods and approaches

Starting to get the ball rolling on the evaluation service,

 have  just emailed everyone who responded positively to the first
questionnaire asking for expressions of interest in participating in
offering a SWI evaluation service

If however you did not respond at the time, and are interested to
collaborate, reply me offlist and I ll put you in the loop

Before dishing out my own (our own, if we collaborate) looking to summarize
existing approaches/methodologies for semantic web interfaces evaluation,
but havent found anything definitive

Have I missed something?

Unless something has been published already and I havent found it yet, I ll
start working on something and circulate the draft for feedback, maybe a
collective paper?
More generally, please let us know if you are aware of (general) interface
evaluation methods and approaches not listed in this paper
(most recent lit rev I could find), or anything else relevant that we
should include in our state of the art survey-
