Ontology - essentially, a formal description of objects and their interrelationships Described using RDF Schema and/or OWL.

Life Sciences

• Gene Ontology provides a controlled vocabulary to describe gene and gene product attributes in any organism. GO terms are organized in directed acyclic graphs (DAGs), which differ from hierarchies in that a 'child' (more specialized term) can have many 'parents' (less specialized terms). GO terms are connected by 'is a' (generalizations) and 'part of' (composition) relationships.

• Biozon - a unified biological resource on DNA sequences, proteins, complexes and cellular pathways. The information in Biozon is logically represented as a graph in which nodes represent some unit of data, and edges indicate a relationship between two nodes.

Datasets

• Open Directory RDF dump The Open Directory Project is the largest, most comprehensive human-edited directory of the Web. It is constructed and maintained by a vast, global community of volunteer editors.
• Wikipedia³ is a conversion of the English Wikipedia into RDF.
• ConceptNet is a semantic network, a freely available commonsense knowledgebase and natural-language-processing toolkit
• WordNet is a semantic lexicon for the English language
  • WordNet Wikipedia article
