AI Planning for Semantic Web Service Composition?
今天看了下这个ppt 摘录点文字:
Jim Hendler's opinion: 01/02/2004 public-sws-ig@w3.org:
Let's start with a pessimistic view…:
I
would point out that the mapping of web services to compositions has largely
been done in the past, even in the best work in
this area, with some simplifications that generally "twist" web services into a planning framework -- there's huge parts of the
web
service world that need to be explored before we can really say AI planning has
shown a success in web services other
than as an evocative idea -- the reason is that a real web services engine will need to deal with (at least):
arguments, etc.)
assumption that change occurs only through the operators under the control of this planner is clearly wrong)
like OWL-S, then we'll see a lot more excitement on the outside - OWL-S is an interesting starting place, but we fool ourselves if
we think it really is going to be widely used for process specification in its current form)
In
fact, I'll wager that it will be absolutely trivial to prove that web services
planning, even w/simplifications, is inherently
undecidable, so we'll need to explore a lot of the issues from the old "dynamic planning" world as well. All this, by the way, I
see as good news - it means this is a fertile and exciting research area for those of us in planning, with good heuristic solutions
being
transitionable. That said, in the past I have
tried to get AI planning people to
think outside the box and
failed miserably,
and I'll be surprised if the web services planning stuff doesn't become an "applied" area being ignored by the bulk of the
research community (who, if you'll apologize my saying so, still have their heads up their you-know-whats worrying about
scaling simple problems in all the wrong ways)
Forgive my pessimism, but the planning community has spent many years resisting change - I don't see why just because we
have a new and potentially revolutionary problem that could expand the field greatly, the leopards will change their spots...

悲观的看法,改ppt还讨论了现有的问题,解决方法,特别是提出wsmo这个来改进一些问题。
