Help with Custom Form

[Pedro Paulo Favato Barcelos]

Dear community,

I am facing a strange behavior in a simple Custom Form I built.

The Custom Form is associated with the creation of a Lexical Entry in an Ontolex project. It is intended to ask the user (every time that a Lexical Entry is entered) to input a Lexical Concept URL and Label and optionally another Lexical Concept URL. The Custom Form also creates the relation evokes between the inputted Lexical Entry and Lexical Concepts. 

Seems that everything works fine, except the Vocbench's presentation of the newly created concepts. As can be seen below, a manually created concept is presented with the correct Label, while the first concept created with the Custom Form is presented with the Lexical Entry name and the Label at the same time, while the third (the optional) concept is presented only with the Entry name.

Why is this happening? Is there a problem with my Custom Form code? As can be seen below, the resulting codes of both the manually created concept and the one created by the Custom Form are similar, so I really don't know why the info is displayed differently!

You can find the Custom Form here attached.

Can someone please help me? =) Thank you very much in advance!

Kind regards, 

Pedro Paulo

Hello Pedro Paulo,

you wrote, "the first concept created with the Custom Form is presented with the Lexical Entry name and the Label at the same time".

This is the normal behavior of the VB3 rendering engine in Ontolex projects. It renders an ontolex:LexicalConcept by appending the labels of all Lexical Entries pointing to it (just like it concatenates all labels of skos:Concepts in SKOS projects). Open Multilingual Wordnet (cf. http://vocbench.uniroma2.it/doc/user/test_drive.jsf) is another example. Having worked quite a lot with Wordnets I was actually surprised to learn that an ontolex:LexicalConcept can have a label of its own.

In other words, the Lexical Concept does not require a label of its own, just delete it from your custom form.

Kind regards

Hi Roland,

Thank you for your contribution!

Vocbench itself created labels for new concepts created with the default way (Concept tab, blue circle with a star icon). When adding a new concept manually, the result is the following:

:c_c694a44a a ontolex:LexicalConcept;
  rdfs:label "Test Lexical Concept"@en;
  skos:inScheme :conceptScheme_58cb06f2;
  skos:topConceptOf :conceptScheme_58cb06f2 .

First I thought Vocbench would use skos:prefLabel, as ontolex:LexicalConcept is a SubClassOf skos:Concept, but it uses rdfs:label, witch was what I used in my Custom Form.

Considering this, I still don't know why Vocbench renders differently the instance created using the default way and the instance created by my Custom Form, as both generate the same code. 

Kind regards,

Hi Pedro Paulo,

you wrote "I still don't know why Vocbench renders differently the instance created using the default way and the instance created by my Custom Form, as both generate the same code."

Both concepts have the "same code", but the context may be different. Note that the code only shows triples where the concepts are in subject position. So you would not see an "incoming link" like (LexEntry_URL evokes Concept_URL).

I set up a new project (Ontolex, local repository, trivialInferencer enabled=true) and imported your custom form. Then I recreated the data shown in your screenshots (one manually created concept; one entry plus two concepts created through your custom form) with the same results.

As a test, I created a new LexEntry without you custom form and a relation (LexEntry evokes Manual_Concept_URL), and guess what?

1. The code of Manual_Concept_URL remains unchanged.

2. The rendering engine appends the new entry's label to Manual_Concept_Label.

I think my test shows that Vocbench's presentation of concepts is the same, wether they are created manually or through your custom form.

Hi Roland,

Thank you very much for the info. I am going to work more on the custom forms and in case of new doubts, I will post in this email thread, ok?

Have a nice weekend and once again thank you for your help!
