"Magic Set Method" and "Backward-chaining inference" not working #7

Closed RomainEndelin closed 10 years ago

RomainEndelin commented 10 years ago

I am trying to follow the tutorial given in https://github.com/RDFLib/FuXi/blob/master/docs/Tutorial.rst, but sections Magic Set Method and Backward-chaining inference do not seem to work.

I use Python 3.3 inside a VirtualEnv

Here is the code for Magic Set Method:

from rdflib import Variable, Namespace
from rdflib import Graph
from FuXi.Rete.RuleStore import SetupRuleStore
from FuXi.Rete.Util import generateTokenSet
from FuXi.Horn.HornRules import HornFromN3
from FuXi.Rete.Magic import MagicSetTransformation, AdornLiteral
from FuXi.SPARQL import RDFTuplesToSPARQL

exNs = Namespace('http://dev.w3.org/2000/10/swap/test/cwm/fam.n3#')

rules = HornFromN3('http://dev.w3.org/2000/10/swap/test/cwm/fam-rules.n3')
factGraph = Graph().parse('http://dev.w3.org/2000/10/swap/test/cwm/fam.n3',format='n3')
factGraph.bind(u'ex',exNs)
dPreds = [exNs.ancestor]

rule_store, rule_graph, network = SetupRuleStore(makeNetwork=True)
network.nsMap = {u'ex':exNs}
closureDeltaGraph=Graph()
network.inferredFacts = closureDeltaGraph

goals = [(exNs.david,exNs.ancestor,Variable('ANCESTOR'))]
for rule in MagicSetTransformation(factGraph,rules,goals,dPreds):
    network.buildNetworkFromClause(rule)
    # network.rules.add(rule)
    print("\t", rule)

And here is the Error:

--------------------------------------------------------------------------

Thank you

gromgull commented 10 years ago

The problems happen deep inside pyparsing, which version do you have installed?

Try up/down-grading it, it may be a pyparsing bug?

RomainEndelin commented 10 years ago

Indeed, it wasn't related to FuXi: I was running pyparsing 1.5.5, it works well after upgrading to 1.5.6.

Thanks :-)
