Subject: RE: JESS: Re: Start on Knowledge Based SystemHi Rich et al,
I saw some of your earlier posts, and you've mentioned KADS a number of times. I looked into it.
<cut>
I need rules (to answer your first question), b/c i have to deal with a lot of raw data (on customers, on system availability, on billing history, on real-time usage etc.) and i want to act upon that data in an informed and knowledgable way.

Three levels of analysis are distinguished:
1. The Process Level has a Process Model, which identifies tasks and data flows in the domain.
2. The System Level has the Co-operation Model, which describes how the system interacts with external 'agents' and how internal 'agents' interact with each other.3. The Expertise Level has the Expertise Model with four sub-layers:
--Domain Layer - static domain knowledge.
--Inference Layer - what inferences can be made from the domain knowledge.
--Task Later - how to apply the knowledge in the above layers to problem-solving.
--Strategic Layer - how to select appropriate problem-solving tasks during execution.It seems that one can use UML for much of this, but what is the best way to model all the models that need modeling? Does one start with the Process Level and work down? How should all this correalate with other modeling efforts, say for non-rules based Object and Information Models?
Fun discussion. Another beer please.... :-)

PS - has anyone looked at the Action Semantic Language? It's a modeling language based on UML that gives one a much richer set of obejcts and grammar to model with. It is nearly a full fledged prototypic programming language. I have references in anyone is interested.

Title: RE: JESS: Re: Start on Knowledge Based System
Someone asked, so here's a link to the most current ASL spec i could
find. According to a gentleman and KC, it is the most recent. There
are efforts underway to create an Executable UML, which is akin to ASL.
That is happening through OMG, i believe.
Cheers,
mark
PS - i
hope this isn't too far off topic.
