Hi,

and thanks for the thorough - and quick - answer !

I tried this and it works.
I updated my lexicon this way :

cat foaf-lexicon.pl
tv_finsg('has-homepage' , iri('http://xmlns.com/foaf/0.1/#homepage') ).
tv_infpl('have-homepage' , iri('http://xmlns.com/foaf/0.1/#homepage') ).
tv_finsg('has-current-project' , iri('
http://xmlns.com/foaf/0.1/#currentProject') ).
tv_infpl('have-current-project' , iri('
http://xmlns.com/foaf/0.1/#currentProject') ).
noun_sg( 'person', iri('http://xmlns.com/foaf/0.1/#Person'), neutr ).

( BTW there must be a better way to write this Prolog, by avoiding pasting
the FOAF prefix at every line, and do a string concatenation ).
BTW the iri/1 predicate should be indicated in the doc.

Then I rerun APE :

 % ape.exe -uri http://eulergui.sf.net/contact.owl  -ulexfile
foaf-lexicon.pl -text 'If P is a person that has-homepage something and
has-current-project something then P is an n:interesting-contact .' -solo
owlxml > interesting-contact2.owl

and now the result is exactly as expected :

<Ontology
    xml:base="http://www.w3.org/2002/07/owl#"
    xmlns="http://www.w3.org/2002/07/owl#"
    ontologyIRI="http://eulergui.sf.net/contact.owl">
  <SubClassOf>
    <ObjectIntersectionOf>
      <ObjectIntersectionOf>
<Class IRI="http://xmlns.com/foaf/0.1/#Person"/>
<ObjectSomeValuesFrom>
  <ObjectProperty IRI="http://xmlns.com/foaf/0.1/#homepage"/>
  <Class IRI="http://www.w3.org/2002/07/owl#Thing"/>
</ObjectSomeValuesFrom>
      </ObjectIntersectionOf>
      <ObjectSomeValuesFrom>
<ObjectProperty IRI="*http://xmlns.com/foaf/0.1/#currentProject*"/>
<Class IRI="http://www.w3.org/2002/07/owl#Thing"/>
      </ObjectSomeValuesFrom>
    </ObjectIntersectionOf>
    <Class
IRI="*http://eulergui.sf.net/contact.owl#interesting-contact*"/>
  </SubClassOf>
</Ontology>

But ... there is a but ...
If load the resulting OWL/XML file into Protégé + ACE View 1.3.1, I found
no way to load my lexicon ( and I looked the doc. ) .
Hence the paraphrases produced are bad .
Moreover , the Lexicon view table is not editable.

I wonder if ACEWiki has a way to load a lexicon , and I think I saw that.

Anyway I recognize that it's not very natural language-like .
