PReditor picks up prepositional usages of "like" (meaning "such as" and tagged as adjective) which should be ignored. Even worse, "unlike" is picked up and included in the .arch files, so you'll see some sentences which at first glance seem to have no "like" predicates at all.

Roleset like.02 Verbnet Class: NONE "semi-modal":

Roles:

Arg0:subject


Arg1:phrasal complement

Examples:

modal (-)
I would like *trace* to find a flight that goes from Boston to Orlando.
Arg0:	I
Argm-MOD:	would
REL:	like
Arg1:	*trace* to find a flight that goes from Boston to Orlando

This proves that "like" cannot be treated as a modal, because English doesn't otherwise allow two modal verbs in a single sentences (with the exception of certain dialects, notably Southern, which might could say such things).
