Open Call for Use Cases

Dear all,

  in our telco on the 3rd of February, we decided to have an open call 
for use cases. On the basis of our discussion at our last teleconference 
on the 9th of March, I have modified the text, in particular shortening 
it (see below).

We also agreed to send this open call to the following 
projects/organizations/mailinglists:

Projects:

- Metanet
- Flarenet
- Molto Project
- Multilingual Web
- IKS

Companies

- SAP
- IBM
- Elsevier
- Mondeca

Mailinglists:

- DBWorld
- Semweb@w3c
- Corpora list
- Linguist list
- ELRA

Are there any additional suggestions?

Please send me your comments by Wednesday 21st of March. I will then 
modify the document accordingly and start sending it short thereafter.

Best regards,

Philipp

*Call for use cases for the ontology-lexicon model*

Since December 2011, the W3C Community Group on Ontology Lexica [1] has 
started its work.

*** Motivation ***

Ontologies have numerous applications and they represent the conceptual 
backbone of the Semantic Web. In fact, significant efforts have gone 
into standardization efforts under the auspices of the W3C to produce 
"recommendations" for data and knowledge representation languages, i.e. 
the Resource Description Framework (RDF) and the Web Ontology Language 
(OWL). However, current web-based knowledge representations languages 
such as OWL and RDF(S) lack the rich linguistic grounding that is 
required for language-mediated access to ontologies. OWL and RDF(S) rely 
on a property rdfs:label to capture the relation between a vocabulary 
element and its (preferred) lexicalization in a given language. This 
lexicalization in some sense provides a lexical anchor that makes the 
concept, property, individual etc. understandable to a user. The 
mechanisms for linguistic grounding available in OWL and RDF(S) are thus 
far from being able to capture the necessary linguistic and lexical 
information that NLP applications working with a particular ontology need.

The mission of the Ontology-Lexicon community group is to develop a 
model for the linguistic grounding of ontologies which allows to 
represent to lexical entries containing information about how ontology 
elements (classes, properties, individuals etc.) are realized in 
multiple languages. A more detailed overview of the scope and goal of 
the working group can be found at [3].

*** Open Call for Use Cases ***

With this call for use cases, we intend to expand the scope of our 
current use cases (see [2]) by including use cases that are inspired in 
more concrete and real applications.

We thus call for participation by industrial stakeholders and 
application developers in the Community Group by providing a description 
of a use case along the template found below.

By this, we offer interested parties to participate in relevant 
standardization activities and have the chance to contribute with their 
ideas to the process of creating a standard for the representation of 
ontology lexica.

We kindly ask you all to provide send the use case description to 
Philipp Cimiano (cimiano@cit-ec.uni-bielefeld.de) until May 3rd. Any 
questions or comments can be addressed to Philipp Cimiano at the above 
email address.

*** Participation in the Group ***

People interested in the group's activities, discussion and 
teleconferences are welcome to join the group at [1].

<TEMPLATE>

*I. Motivation*

**

This should contain a short motivation of the use case, including a 
description of the application context and why it is relevant to specify 
the meaning of words with respect to a given ontology in the context of 
the application.

**

*II. Description of the use case*

**

This section should describe the use case in more detail, specifying how 
the lexicon-ontology interface would need to look like from the point of 
view of the application and how the lexicon-ontology interface is 
exploited in the context of the given application. If available, the 
ontology for the application should be briefly described.

**

*III. Limitations of existing models *

**

This section should discuss existing models and their limitations with 
respect to the needs of the application of question.

**

*IV. Example*

**

This section should provide a concrete example illustrating what kind of 
knowledge should be stated in the lexicon-ontology interface from the 
point of view of the application and how it would be exploited by the 
application.

**

*V. Requirements*

**

This section is optional and might already advance concrete requirements 
on the lexicon-ontology model.
