Data category
• The result of the specification of a given data field– A data category is an elementary descriptor in a linguistic
structure or an annotation scheme.
• Model consists of 3 main parts:– Administrative part

Data Category Registry• ISOcat is a free service: anyone can access it or register as an
expert and create/share his/her own data categories.
• Data categories can be submitted to the standardization process, in which case they are assigned to a Thematic Domain Group which judges it.
• At regular intervals, snapshots of the standardized subset of the DCR will be submitted to ISO.

Annotating linguistic resources
February 19, 2010
• Schema language support for equivalence:– for example ODD from TEI
<elementSpec ident="pos"> <equiv name="partOfSpeech" uri="http://isocat.org/datcat/ISO-DC-369"/> …
</elementSpec>
• Annotation using dcr:datcat attribute:– for schemas or instances– for example RelaxNG schema
<rng:element name="partOfSpeech" dcr:datcat="http://isocat.org/datcat/ISO-DC-369" > <rng:choice>
<rng:value dcr:datcat="http://isocat.org/datcat/ISO-DC-370"> verb
</rng:value> <rng:value dcr:datcat="http://isocat.org/datcat/ISO-DC-371">
noun </rng:value>
</rng:choice></rng:element>
• XML oriented, is more needed?

Data categories as RDF resources
February 19, 2010
:headword dcr:datcat <http://isocat.org/datcat/DC-258> ; rdfs:label "head word"@en ; rdfs:comment "A lemma heading a dictionary entry."@en ; rdfs:label "lemma"@nl ; rdfs:comment "Het eerste woord van een artikel in een
woordenboek."@nl .
:partOfSpeech dcr:datcat <http://isocat.org/datcat/DC-396> ; rdfs:label "part of speech"@en ; rdfs:comment "A category assigned to a word based on its grammatical and
semantic properties."@en .
A domain modeling approach: :headword a rdfs:Class .
:partOfSpeech a rdf:Property ; rdfs:domain :headword .
Alternative approach:
:headword a rdfs:Class .
:partOfSpeech a rdf:Class.
:hasPartOfSpeech a rdf:Property ; rdfs:domain :headword rdfs:range:partOfSpeech.
:noun a partOfSpeech.

ISOcat status
February 19, 2010
• ISOcat is under active development:– Now:
• You can access public data categories and selections• You can create your own data categories and selections• You can share your data categories and selections with others (everyone, or a
specified group)
– In progress:• Cleanup of profiles by TDGs• Standardization workflow• Some social features (forum to discuss specific data categories)• Import external ‘data category’ sets, such as:
– parts of the ISO Concept Database– Dublin Core– TEI
– Future:• High availability (mirrors)• Relation registry

ISOcat workshop
• Utrecht, Thursday March 25, 2010• Especially aimed at supporting Call 1 projects• Signup at: www.clarin.nl• Program:– A deeper introduction to ISOcat– A tutorial on using ISOcat– How to annotate specific linguistic resources?
February 19, 2010
Invitation
