Getting wrong axioms - Githubissues

Hebaallahibrahim commented 5 years ago

Hello, I am working on RDF/XML parser that parses RDF/XML ontology and converts it to OWLAxiom using ontology.axioms() method. I notice that in the output I have some wrong results:

every rdfs:domain is converted to AnnotationPropertyDomain instead of DataPropertyDomain or ObjectPropertyDomain even it is defined as objectProperty or dataProperty.
every rdfs:subPropertyOf is converted to SubAnnotationPropertyOf instead of SubDataPropertyOf or SubObjectPropertyOf
get the error “Unparsed triple” when having restrictions such as someValuesFrom, and I have no axiom for that. Do you have any idea how can I handle such wrong results?

Hi, which OWLAPI version and what input ontology are you using?

Hebaallahibrahim commented 5 years ago

I use RDF/XML ontology, actually I don't use the version I use the dependency like this without mention the version

     <dependency>
            <groupId>net.sourceforge.owlapi</groupId>
            <artifactId>owlapi-api</artifactId>
        </dependency>
        <dependency>
            <groupId>net.sourceforge.owlapi</groupId>
            <artifactId>owlapi-apibinding</artifactId>
        </dependency>

You might not mention the version in your pom file but maven must resolve it to a specific owlapi version when compiling your code. We need to know what maven is choosing - it should be printed out when you run a build, or made explicit in your ide project configuration.

I need to see the input ontology - just knowing it's rdf/XML is not sufficient.

Hebaallahibrahim commented 5 years ago

I have Maven 3 (version 3.3.9) and the input ontology is univ-bench.rdf

ignazio1977 commented 5 years ago

The maven version is not what we need. In the output, Maven will also say what version each of the libraries in the classpath are. If not, please add a version so we're sure we're talking about the same code.

There are no sub data property axioms in your ontology.

With OWLAPI 4 and OWLAPI 5, I get no unparsed triples:

Hebaallahibrahim commented 5 years ago

I have added the version 5.1.5 to the dependency and still face the same error. and my question was general with another ontology the same problem for subdata and subobject properties

Hebaallahibrahim commented 5 years ago

and fr the unparsed triple, if we have this record

<rdf:Description rdf:nodeID="node1d7hctiisx2">
    <rdf:type rdf:resource="http://www.w3.org/2002/07/owl#Restriction"/>
    <owl:onProperty rdf:resource="http://swat.cse.lehigh.edu/onto/univ-bench.owl#headOf"/>
    <owl:someValuesFrom rdf:resource="http://swat.cse.lehigh.edu/onto/univ-bench.owl#Department"/>
</rdf:Description>

I got this INFO:

1158 INFO org.semanticweb.owlapi.rdf.rdfxml.parser.OWLRDFConsumer:458 - Unparsed triple: _:genid-nodeid-node1da6h2p9lx25 -> http://www.w3.org/2002/07/owl#someValuesFrom -> http://swat.cse.lehigh.edu/onto/univ-bench.owl#Department 1210 INFO org.semanticweb.owlapi.rdf.rdfxml.parser.OWLRDFConsumer:458 - Unparsed triple: _:genid-nodeid-node1da6h2p9lx26 -> http://www.w3.org/2002/07/owl#onProperty -> http://swat.cse.lehigh.edu/onto/univ-bench.owl#headOf

Hebaallahibrahim commented 5 years ago

and also have such error:

3164 ERROR org.semanticweb.owlapi.rdf.rdfxml.parser.OWLRDFConsumer:1797 - Entity not properly recognized, missing triples in input? http://org.semanticweb.owlapi/error#Error1 for type Class

ignazio1977 commented 5 years ago

I still cannot replicate the issue - the records are parsed as expected on my machine with version 5.1.5.

Can you add this code at the beginning of your program and past the result? I want to make sure there's only one OWLAPI version around.

    System.out.println("CheckOntology.should() " + System.getProperty("java.class.path"));

Hebaallahibrahim commented 5 years ago

the output of the code is :

I've tried replicating this by replicating the classpath you've shown and still no issue here. I'm not sure what the problem is, there's no conflicting OWLAPI version nor anything else that seems wrong.

Can you share the exact code you're using to load the ontology?

The only warning I see is related to the file not having an xml:base

2019-05-08 20:08:34:825 +0100 [main] INFO org.semanticweb.owlapi.rdf.rdfxml.parser.AbstractState - Notice: root element does not have an xml:base. Relative IRIs will be resolved against file:/univ-bench.txt 2019-05-08 20:08:34:975 +0100 [main] DEBUG org.semanticweb.owlapi.rdf.rdfxml.parser.TripleLogger - Total number of triples: 305

So it could be that having the file in a different location might change some of the parsing.

Here is that code I use to load the ontology:

def getOWLOntology(model: Model): OWLOntology = {
    val in = new PipedInputStream
    val o = new PipedOutputStream(in)

    val man = OWLManager.createOWLOntologyManager()
    new Thread(new Runnable() {
          def run() : Unit = {
            model.write(o, "TURTLE")

            try {
              o.close()
            } catch {
              case e: IOException => e.printStackTrace()
            }

          }
        }).start()
        val ontology : OWLOntology = man.loadOntologyFromOntologyDocument(in)
    ontology

  }

Thank you, I'm wondering if in your code it's possible for the reader to give up reading before the writer has finished writing.

Could you put the intermediate Turtle output in a file and attach it here? It's also possible the failure comes from a bug in the turtle format handler. The writing is form a Jena model, right?

Hebaallahibrahim commented 5 years ago

Yes the writing is from Jena , and here is the intermediate Turtle output, out.txt

ignazio1977 commented 5 years ago

With the Turtle content, I can replicate the issue. I believe the problem is in the translation to Turtle. Jena outputs a warning:

0 WARN  org.apache.jena.riot.system.ErrorHandlerFactory$ErrorLogger:95 - [line: 6, col: 138] {W108} Not an XML Name: 'http://swat.cse.lehigh.edu/onto/univ-bench.owl#node1d7hctiisx1'

And in the Turtle content, there are many structures like this:

[ <http://www.w3.org/2002/07/owl#someValuesFrom>
      <http://swat.cse.lehigh.edu/onto/univ-bench.owl#Department> ] .

Where there is a blank node acting as subject of a triple, with the triple unconnected to anything else.

Looks to me like Jena does not like the ids used to connect the elements of the lists in your XML input file, and is creating incorrect Turtle. The Turtle content cannot be parsed properly by OWLAPI, and that's the origin of the errors you're seeing.

You can try a few changes:

Give the XML input directly to OWLAPI
Save to a different intermediate format
Change the input to have the lists as nested elements rather than distinct Description elements linked with node ids.

Hebaallahibrahim commented 5 years ago

Unfortunately, I am unable to give the input file directly to OWLAPI because I am dealing with large files (up to 20 GB)

Can you give me an example of nested lists for restrictions in RDFXML, because when I am trying to go with that, Jena produces an error.

ignazio1977 commented 5 years ago

You could try using RDF/XML-ABBREV for the intermediate format - it should be identical to RDF/XML as used by OWLAPI.

I've saved your example file as RDF/XML with OWLAPI and got the file below:

I need the ontology to be parsed in RDFXML format using <Description> tags. How can I write nested <Description> tags?

I used RDF/XML-ABBREV for the intermediate results and the same errors raised, plus no xml:baseINFO raised for every parsed record even after adding the xml:base="http://swat.cse.lehigh.edu/onto/univ-bench.owl" line to the rdf file !!!!!!!

ignazio1977 commented 5 years ago

I don't believe Description elements can be nested for lists.

I'd try the process in reverse - take an ontology with lists (such as the XML above), load it in Jena and output it as RDF/XML, it should produce correct RDF output.

Failing that we'll have to dig deeper on why Jena doesn't deal well with this format. I can't spot anything obviously wrong with it.

An example of an intersection containing a list:

<owl:Class rdf:about="http://swat.cse.lehigh.edu/onto/univ-bench.owl#Employee">
<owl:intersectionOf rdf:parseType="Collection">
  <owl:Class rdf:about="http://swat.cse.lehigh.edu/onto/univ-bench.owl#Person"/>
  <owl:Restriction>
    <owl:someValuesFrom>
      <owl:Class rdf:about="http://swat.cse.lehigh.edu/onto/univ-bench.owl#Organization"/>
    </owl:someValuesFrom>
    <owl:onProperty>
      <owl:ObjectProperty rdf:about="http://swat.cse.lehigh.edu/onto/univ-bench.owl#worksFor"/>
    </owl:onProperty>
  </owl:Restriction>
</owl:intersectionOf>
<rdfs:label>Employee</rdfs:label>
</owl:Class>

:Chair  a                   owl:Class ;
    rdfs:label          "chair" ;
    rdfs:subClassOf     :Professor ;
    owl:intersectionOf  ( :Person
                          [ a                   owl:Restriction ;
                            owl:onProperty      :headOf ;
                            owl:someValuesFrom  :Department
                          ]
                        ) .

ignazio1977 commented 5 years ago

owl:Class can be replaced with

<rdf:Description rdf:about="http://swat.cse.lehigh.edu/onto/univ-bench.owl#Employee">
    <rdf:type rdf:resource="http://www.w3.org/2002/07/owl#Class"/>

Yes I can handle the classes, but not the restrictions
