“DBpedia and the live extraction of structured data from Wikipedia”

Purpose – DBpedia extracts structured information from Wikipedia, interlinks it with other knowledge bases and freely publishes the results on the web using Linked Data and SPARQL. However, the DBpedia release process
is heavyweight and releases are sometimes based on several months old data. DBpedia-Live solves this
problem by providing a live synchronization method based on the update stream of Wikipedia. This paper seeks to address these issues.
Design/methodology/approach – Wikipedia provides DBpedia with a continuous stream of updates, i.e. a stream of articles, which were recently updated. DBpedia-Live processes that stream on the fly to obtain RDF data and stores the extracted data back to DBpedia. DBpedia-Live publishes the newly added/deleted triples in files, in order to enable synchronization between the DBpedia endpoint and other DBpedia mirrors.
Findings – During the realization of DBpedia-Live the authors learned that it is crucial to process Wikipedia
updates in a priority queue. Recently-updated Wikipedia articles should have the highest priority, over mappingchanges and unmodified pages. An overall finding is that there are plenty of opportunities arising from the emerging Web of Data for librarians.
Practical implications – DBpedia had and has a great effect on the Web of Data and became a crystallization point for it. Many companies and researchers use DBpedia and its public services to improve their applications and research approaches. The DBpedia-Live framework improves DBpedia further by timely synchronizing it
with Wikipedia, which is relevant for many use cases requiring up-to-date information.
Originality/value – The new DBpedia-Live framework adds new features to the old DBpedia-Live framework, e.g. abstract extraction, ontology changes, and changesets publication.
