FYI: Open Call for Use Cases for Ontology-Lexicon Model

FYI Body:	The W3C Community Group on Ontology Lexica started work in December 2011 http://www.w3.org/community/ontolex/ Motivation Ontologies have numerous applications and they represent the conceptual backbone of the Semantic Web. In fact, significant work has 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 representation 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 provides some kind of 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 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 by concrete, real-life applications. We thus call for participation of industrial stakeholders and application developers in the Community Group by providing a description of a use case using the template found below. By this, we offer interested parties the opportunity to participate in standardization activities that are relevant and potentially beneficial for their application development, and contribute their ideas to the process of creating a standard for the representation of ontology related lexicons. Please send use case descriptions to Philipp Cimiano (cimiano@cit- ec.uni-bielefeld.de) until May 3rd. Any questions or comments can be addressed to Philipp Cimiano at the same email address. Participation in the Group People interested in the group’s activities, discussion and teleconferences are welcome to join the group at [1].

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 what the ontology-lexicon interface would need to look like from the point of view of the application and how the ontology-lexicon 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 in question. IV. Example This section should provide a concrete example illustrating what kind of knowledge should be stated in the ontology-lexicon 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 ontology-lexicon model.
