linked data, free pictures, and markets for semantic data
DESCRIPTION
Ookaboo is a collection of about 1,000,000 Creative Commons images gathered from social media to 500,000 Linked Data concepts from Freebase and DBpedia. Ookaboo’s semantic API and RDF dump let applications connect topic such as people, places, species and things to free pictures with almost perfect precision. To create Ookaboo’s photo collection and user interface, I had to extensively clean Linked Data and construct a knowledge base about “commonsense” topics such as grammar, the relative importance of things, offensiveness, and the categorization and naming of things. Had this knowledge been commercially available, I could have more time acquiring images and building a community. Although free Linked Data defines a shared vocabulary that enables interoperation, next generation text analysis, data integration, and content generation systems will depend on reusable knowledge bases that take resources and specialized skills to create – a market in semantic data will fill this need.TRANSCRIPT
