Key Points descriptionSuggested Task DelegationFiles Needed & previous work

Project Team A (1/4)Embed DR-Prolog by extending a Jade Agent

java classUse 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 B (1/3)Read The Proof Explanation Paper (CS566 2007

project)Understand the accompanying code

Uses an Invoker Object instead of InterprologCreation of XML for Proof Explanation

Embed it to a Jade Agent java classFind a way to incorporate the option for using the

Proof Explanation componenti.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

Future work for Team BLater 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 CRead the Proof explanation PaperBrainstorm …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!!!
