The Semantic Web is a vision and set of technologies that make it possible to share information on the Web in a way that large and diverse sets of data can be easily merged and queried by machines.
Annomation uses a number of Semantic Web technologies including
- The Friend Of A Friend (FOAF) vocabulary for managing user accounts
- The Dublin Core vocabulary for recording titles, creators and so on
- The Timeline Ontology for associating annotations with time points in the videos
- The Simple Knowledge Organization System (SKOS) for understanding hierarchical classification systems
- The W3C Basic Geo vocabulary based on WGS84
- The Sesame RDF store
Annomation also uses Linked Data services and information sources including
- Geographical search from GeoNames
- Library classifications from Dewey and Library of Congress
- Entity recognition from Zemanta
- Open University course data from data.open.ac.uk
The result of using Semantic Web technologies means data created in Annomation can be reused in serendipitous ways by anyone interested in the annotations. The annotation data can be recombined with data from other sources on the Semantic Web to create new data sets and Semantic mash-ups. The same annotations can be used by Open University staff to find material for new courses, students looking for extra sources on a subject that interests them, programme makers searching for library footage, or anything else someone, somewhere, can imagine. An example application, created by KMi and OBU in tandem with Annomation, is SugarTube.
