Social Semantic Collaborative Filtering Ontology

SSCF Ontology (see http://s3b.corrib.org/sscf/0.2/ for more information) describes objects and properties that are used by Social Semantic Collaborative Filtering.
SSCF is a personal knowledge management system. User builds a personal hierarchy of directories (personal taxonomy) and fills it with a links to interesting resources (web bookmarks, MultiBeeBrowse bookmarks). Users can share the gathered knowledge with others by importing others' directories. System provides also an import feature - one can import resources stored in different bookmarking system (like del.icio.us)

Class: sscf:WebResource

Special kind of Resource. Resource which is a link to the page in a Web, URL.

sub-class-of:

Property: sscf:accesibleTo

Holds the resource access policy, e.g., a FOAFRealm realm rule:
F[mailto:foo@bar.com]1.4

Range:
xsd:string

Property: sscf:annotates

Links resource with its annotation.

OWL Type:

sioc:Post
Range:
sscf:Resource

Property: sscf:createdBy

Points to Person that create the Resource

OWL Type:
ObjectProperty
Domain:

Property: sscf:follows

OWL Type:

Property: sscf:hasTag

OWL Type:

Property: sioc:has_container

Used by Annotation module to export data. Represents the following properties: rdf:type, sscf:annotates, sscf:isEvaluatedWith.

Property: sioc:has_creator

  • Used by Annotation module to export data. Shows the creator/owner of sscf:Resource, sscf:Evaluation or sioc:Post
  • Used to keep Creator of the Evaluation (Domain - sscf:Evaluation, Range - foaf:Person)

The sioc:has_creator property links a Post to its author's User account. Thus, we can follow the link from the post to the creator and locate the other posts by the same User.

The community can be seen as a network of posts with users linked to each post, and there is also a network of other posts created by a given user stemming from there. We can use this information in community sites to locate more contributions by the given author.
