EODM - POC to extract relationships [message #61088]

Hello,
I am evaluating / doing a Proof Of Concept for extracting relationships from
triples. I am looking for some (step by step) tutorial .... is there any
tutorial that walks through / explains the OWL / RDF reasoner ? I looked in
the samples ... but thats bit "cryptic" :-(

This is what I am trying to achieve : I want to give a bunch of triples to
the (OWL or RDF) reasoner : something like
{V1, V3}, {V5, V7}, {V9, V11}
{V1, V2}, {V5, V4}, {V9, V6}

I want the reasoner to tell me that there exists relationship between : (V2,
V3) and (V4, V7) and (V6, V11)

Is there any sample that demonstrates something similar to this ...

Any help would be very much appreciated. ...

Thanks

Sai

Sai,

It would be best asked on the EODM newsgroup, which I've added to the list.

Sai,

The EODM RDF Reasoner is implemented by the RDF reasoning rules with graph
algorithm and the OWL Reasoner is impleneted with the structural
subsumption algorihtm which currently only support TBox reaonsing. In
fact, I am not understand the example you mentioned. Is {V1, V3} a triple?
If yes, what is the property between them?

I apologize for not replying (clarifying my question) earlier ...=20
I have a Java application is being fed by to seperate (input) streams. =
During the parsing / processing of those, I will come across some =
business rules like, V1 =3D V3 from the first stream and another rule =
like, V2 =3D V1 from the second stream. From this, I want to infer that =
there is a relationship between V2 and V3. I want to know how to =
represent this in RDF XML. If my understanding is correct (from the =
primer and some reading), I can represent them as tripes as
{V1 equal V3} and {V2 equals V3}

In RDF / XML as :

<?xml version=3D"1.0"?>

<rdf:RDF=20
xmlns:rdf=3D"http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:rdfs=3D"http://www.w3.org/2000/01/rdf-schema#"

<gxs:equals rdf:resource=3D"http://www.gxs.com/V1" />=20
</rdf:Description>
=20
</rdf:RDF>

Is this correct? If so, how can I use the reasoner to infer that there =
is a relationship between V2 and V2

Thanks

Hi sai,

Now I understand your question. :-)

First of all, the RDF triples that you showed did represent the {V1 equal
V3}... However, a RDF/RDFS reasoner only support standard RDF/RDFS
reasoning, which are defined by RDF/RDFS semantics. You can reference
http://www.w3.org/TR/rdf-mt/ (chapter 7 shows the entailment rules that
standard RDF/RDFS reasoner use). Therefore, a standard RDF/RDFS reasoner
can not make reasoning that you want, because it does not understand the
semantic of user-defined terminology such as "gxs:equals".

To support user defined business rules, you can use a external rule-based
engine. I think that can solve your problem.

Hello=20
Thanks for getting back to me. It is very much appreciated. =20

However, I have few follow-up questions / clarifications :

As I mentioned earlier, from the two Java streams, I will be getting the =
rules like, V1 =3D V3 and V2 =3D V1. (In terms of business terminology, =
I could say, V1 is mapped to V3 and V2 is mapped to V1. So, we can =
infer a mapping between V3 and V2)=20

I was thinking of constructing RDF XML on the fly and use the reasoner. =
Would it be possible to "some how" represent this relationship using =
standard RDF/RDFS semantics (so that the standard RDF/RDFS reasoner =
could be used to infer relations) ? How to represent them in using =
standard RDF?
=20
You also mentioned about external rule-based engine ... can you please =
point to one of them? Is Pellet Owl Reasoner support this type of =
scenario ? (http://www.mindswap.org/2003/pellet/index.shtml)

To give a detailed (business) picture ... I am thinking of using RDF =
reasoner to reason business documents and their mappings. For example, =
assume that you are electronically receiving an Invoice and processing =
that. In this scenario, you will come across business rules like :=20

InvoiceNumber =3D (take the values from position 10 to 15 from the =
stream) [This is analogous to V1 =3D V3]

ReferenceNumber =3D InvoiceNumber [This is analogous to V2 =3D =
V1]

From the above statements, you can infer that=20
ReferenceNumber =3D (take the values from position 10 to 15 from the =
stream) [This is analogous to V2 =3D V3]

Your advice and help is very much appreciated.

Thanks
