Civet uses NLP techniques to determine the keywords in the provided text. But it does not stop there: it analyzes these words and determines the most appropriate meanings linked to concepts from vocabularies, such as WordNet and Polish version of the OpenThesaurus, both published as RDF/SKOS graphs on Linked Open Data.

Civet also discovers names of people and places, and uses other LOD sources, such as DBPedia or GeoNames, to annotate these names with concepts from those vocabularies.

The initial plain text becomes an RDFa document with key words, phrases and names referencing Linked Open Data concepts. Civet uses repository of previously analyzed texts to recommend semantically similar texts to the given one.

Civet was built to work with Polish texts, but we currently work on the English and Italian version of the service.

We plan the presentation as follows:

  • Discuss the main design objectives of both the annotation and the vocabulary publishing service
  • Give an overview of the algorithms we use to extract the meaningful concepts from given text
  • Present how to turn legacy vocabularies into RDF/SKOS graphs
  • Discuss various pitfalls one can stumble upon when building such services
