ABSTRACT

This tutorial will demonstrate how attendees can move beyond using rule 
based reasoning to build intelligent decision support systems.  In this 
tutorial we focus upon supplementing deductive reasoning with case based 
reasoning, neural networks and intelligent information retrieval.  Applications 
of these principles in law, management and finance will be provided.

The tutorial will provide background knowledge necessary to understand the 
lectures of Professor Sowa and Sycara.


OUTLINE OF THE TUTORIAL

*	Introduction 
	- The need for intelligent decision support systems in finance, 
          management and law

*	Strategies for providing Intelligent Decision Support Systems 
        - Intelligent Information Retrieval, Deductive Reasoning, Case Based 
          Reasoning

* 	Intelligent Information Retrieval 
        - Keyword retrieval, Boolean retrieval, Vector space models,
          Probabilistic models.

*	Introduction to deductive reasoning systems 
	- Production rule systems, Logic programming approaches,
          Object oriented approaches.

*	Case based reasoning systems 
	- What are based reasoners? Why use case based reasoners? 
	  Constructing differing types of case based reasoners. Examples of 
          case based reasoners: MEDIATOR, PERSUADER, CASEY, HYPO, PROTOS 
          Automated design of case bases.

*	Integrating deductive and case based reasoning 
	- Using the object oriented approach to build integrated systems. 
	  The relative benefits and disadvantages of blackboard systems and 
	  distributed artificial intelligence to build integrated systems. 
	  Examples of integrated systems: ANAPRON, CABARET, GREBE, IKBALS, 
          PROLEXS

*	Combining information retrieval, deductive reasoning, neural networks 
	and case based reasoning 
	- Conceptual information retrieval and neural networks, Bayesian 
          Inference Networks, hypertext, The DATALEX workstation, AIR and 
          SCALIR, WIN (Westlaw Is Natural), SPLIT UP.

*	Conclusion


ASSOCIATED PRACTICAL WORK

There will be two practical components in the tutorial

     Participants will have the opportunity to examine and use integrated
     systems built by the tutorial presenters: in particular IKBALS and
     FLORENCE -- integrated rule based/case based reasoners -- and SPLIT-UP
     an integrated rule based/neural network system.

     Participants will build legal knowledge based systems under the 
     guidance of the tutorial presenters. They will have the opportunity to
     examine how to supplement rule based reasoning with one or more of the 
     reasoning and retrieval approaches discussed in the tutorial.

--------------------------------------------------------------------------------
Examples of structured sequence of tutorials:
--------------------------------------------------------------------------------

There are couple of structured sequence of tutorials that one could adopt.
For example, if the participant is interested in logic/theoretical basis of
AI, then he/she may want to select the following sequence:

Day 1   9.30 - 10.30: Introdution to AI
       11.00 - 12.30: NMR(t)
        2.00 -  3.30: NMR(t)
        4.00 -  5.30: NMR(p)

Day 2   9.00 - 10.30: CBR(t)    
       11.00 - 12.30: CBR(t)
        2.00 -  3.30: CBR(t) 
        4.00 -  5.30: CBR(p)

Alternatively, if the participant is more interested in the applications of
AI, then the following sequence may be more suitable:

Day 1   9.30 - 10.30: Introdution to AI
       11.00 - 12.30: IDSS(t)
        2.00 -  3.30: IDSS(t)
        4.00 -  5.30: IDSS(p)

Day 2   9.00 - 10.30: FLFC(t)
       11.00 - 12.30: FLFC(t)
        2.00 -  3.30: FLFC(p) 


If the interest is in Machine Learning/Knowledge Acquisition, then the
possible sequence may be:

Day 1   9.30 - 10.30: Introdution to AI 
       11.00 - 12.30: TFML(t)
        2.00 -  3.30: TFML(t)
        4.00 -  5.30: TFML(t)

Day 2   9.00 - 10.30: ILDB(t)  or  KAM(t)    
       11.00 - 12.30: ILDB(t)  or  KAM(t)
        2.00 -  3.30: ILDB(p)  or  KAM(d)

Another possible sequence may be:

Day 1   9.30 - 10.30: Introdution to AI
       11.00 - 12.30: EC(t)
        2.00 -  3.30: EC(t)
        4.00 -  5.30: EC(p)

Day 2   9.00 - 10.30: HS(t)    
       11.00 - 12.30: HS(t)
