 Project Teams
 Key Points description
 Suggested Task Delegation
 Files Needed & previous work
Project Team A (1/4)
 Embed DR-Prolog by extending a Jade Agent java class
 Use Interprolog for handling the external Prolog
Interpreter (XSB)



Load Metaprogram & Theory files as well as Facts written in
DR-Prolog Syntax
Make queries
Retrieve the result(s) – see Interprolog FAQ for multiple
results
Project Team A (2/4)
 Create a small Library providing the following
 Convert the RuleML Syntax into Native DR-Prolog


Using XSL Transformation or XML Parsing
Create support for number comparison
 Add predicates into the Metaprogram – need for possibly a
second level processing using Java
 Convert the standard format of results returned by XSB
into RDF File
* For the RuleML & RDF files follow the current format (version) used in the carlo
example (EMERALD DEMO)
 This Library will be used later on also byTeam B
Project Team A (3/4)
 Previous slides cite the Key Points – Tasks for Team A
 These points can be used for Task Delegation among
the team members
 Further division of team A

Sub team for each task
*It is a suggestion you do not have to follow it
Project Team A (4/4)
 XSB
 Prolog Interpreter
 http://xsb.sourceforge.net/
 DR-Prolog Metaprogram
 Defeasible Reasoning Prolog Implementation
 http://www.csd.uoc.gr/~hy566/amb_metaprogram.P
 Interprolog
 Communication with XSB via java programming
 http://www.declarativa.com/interprolog/default.htm
Project Team B (1/3)
 Read The Proof Explanation Paper (CS566 2007
project)
 Understand the accompanying code
 Uses an Invoker Object instead of Interprolog
 Creation of XML for Proof Explanation
 Embed it to a Jade Agent java class
 Find a way to incorporate the option for using the
Proof Explanation component
 i.e. when the reasoner is to provide the explanation

Register appropriate service of reasoning agent ? (like reg.txt)
Project Team B (2/3)
 Previous slide cite Key Points – Tasks for Team B
 All team members should have an understanding of
the paper and code for Proof Explanation
Project Team B (3/3)
 XSB
 Prolog Interpreter
 http://xsb.sourceforge.net/
 Proof Explanation
 Proof Explanation Paper

http://www.csd.uoc.gr/~hy566/proofExplanation.pdf
 Project Files & DR-Prolog Metaprograms


Future work for Team B
 Later on team A will provide team B with the specifics
of the library for the RuleML parser and rdf result
converter , so as to feed with a Rulebase the proof
explanation component
 This could mean that agents of Teams A & B could be
merged into one and the RDF result File depending
the option provided by Team B could contain the XML
Proof Explanation (something to think about)
*this is a suggestion
Project Team C
 Read the Proof explanation Paper
 Brainstorm …
 Later on coordinate with Team B for a walk-through of
the code available up to that time, in order to
implement the appropriate agent providing the proof
checking service and register it to the Emerald
Framework.
That’s all for now!!!
