Wikidata is rapidly emerging as a key resource for a multitude of online tasks such as Speech Recognition, Entity Linking, Question Answering, or Semantic Search. The value of Wikidata is directly linked to the rich information associated with each entity – that is, the properties describing each entity as well as the relationships to other entities. Despite the tremendous manual and...

Ostapuk, Natalia ; Difallah, Djellel Eddine ; Cudré-Mauroux, Philippe

In: Proceedings of the 1st Wikidata Workshop (Wikidata 2020) co-located with 19th International Semantic Web Conference (ISWC 2020), Virtual Conference, November 2-6, 2020, 2020, vol. 2773, p. 1-15

Wikidata is a key resource for the provisioning of structured data on several Wikimedia projects, including Wikipedia. By design, all Wikipedia articles are linked to Wikidata entities; such mappings represent a substantial source of both semantic and structural information. However, only a small subgraph of Wikidata is mapped in that way – – only about 10% of the sitelinks are linked to...

Swisslink: high-precision, context-free entity linking exploiting unambiguous labels

Prokofyev, Roman ; Luggen, Michael ; Difallah, Djellel Eddine ; Cudré-Mauroux, Philippe

In: Proceedings of the 13th International Conference on Semantic Systems, 2017, p. 65–72

Webpages are an abundant source of textual information with manually annotated entity links, and are often used as a source of training data for a wide variety of machine learning NLP tasks. However, manual annotations such as those found on Wikipedia are sparse, noisy, and biased towards popular entities. Existing entity linking systems deal with those issues by relying on simple statistics...
