LoCloud D3.3: Metadata Enrichment services

Soroa, Aitor; Otegi, Arantxa; Agirre, Eneko; Agirre, Rodrigo

Metadata enrichment services automatically link Cultural Heritage (CH) items with external information such as DBpedia pages or vocabulary concepts. Metadata enrichment is a useful task which assists users by providing contextual information about a particular item. It also helps in the task of categorizing CH items with relevant terms and concepts from a particular vocabulary. Metadata enrichment comprises two di_erent micro-services:

  • Background link  micro-service, which automatically links CH items to background information contained in pages from an external resource like Wikipedia or DBpedia.
  • Vocabulary matching  micro-service, which automatically links metadata relevant to relevant classes in a provided vocabulary.

The background link micro-service relies on DBpedia Spotlight, a state-of-the-art tool for performing Named Entity Disambiguation (NED). DBpedia Spotlight was chosen because it performed best in our experiments, as shown in the deliverable.

LoCloud was funded by the European Commission's ICT Policy Support Programme. Grant Agreement number: 325099
