Extracting Events from Wikipedia as RDF Triples Linked to Widespread Semantic Web Datasets [chapter]

Carlo Aliprandi, Francesco Ronzano, Andrea Marchetti, Maurizio Tesconi, Salvatore Minutoli
2011 Lecture Notes in Computer Science  
We extract events from the KAF semantic annotation and then we structure each event as a set of RDF triples linked to both DBpedia and WordNet.  ...  In this paper we describe an approach to enhance the extraction of semantic contents from unstructured textual documents, in particular considering Wikipedia articles and focusing on event mining.  ...  This work is partially funded by the European Commission (KYOTO project, ICT-2007-211423).  ...

Event-QA: A Dataset for Event-Centric Question Answering over Knowledge Graphs [article]

Tarcísio Souza Costa, Simon Gottschalk, Elena Demidova
2020 arXiv   pre-print
As new event-centric knowledge graphs emerge, datasets for such questions gain importance. In this paper we present the Event-QA dataset for answering event-centric questions over knowledge graphs.  ...  Whereas most of the existing QA systems and datasets focus on entity-centric questions, very little is known about the performance of these systems in the context of events.  ...  -VoID description: Machine readable description of the dataset in RDF. -List of DBpedia events and entities covered by the dataset.  ...

Modelling Provenance of DBpedia Resources Using Wikipedia Contributions

Fabrizio Orlandi, Alexandre Passant
2011 Social Science Research Network  
DBpedia is one of the largest datasets in the linked Open Data cloud.  ...  Yet, in spite of its authoritative aspect, there is no work so far tackling the provenance aspect of DBpedia statements.  ...  Then, since the DBpedia content is directly extracted from Wikipedia, the same trust and quality values can be propagated to the DBpedia dataset.  ...
