UXExperimentalTerms.kif 783-797

If X is the list of items viewed by Y, Z is an instance of accessing web page, and equal the first of X and Z, then there doesn't exist W such that W is an instance of accessing web page, Y is an agent of W, and the time of existence of W happens earlier than the time of existence of Z

consequent

(=> (and (inList ?INT ?LIST) (equal ?LIST (TimeIntervalListFn ?TIME ?DUR))) (equal (BeginFn ?TIME) (BeginFn (FirstFn ?LIST))))	Weather.kif 3233-3240	If X is a member of Y and equal Y and ConsecutiveTimeIntervalList for at Z at W is contained in TimeIntervalListFn, then equal the beginning of Z and the beginning of the first of Y
