Description

Implement an Engine in Stanbol for disambiguating YAGO's entities. The implementation should use a client of the service specified at STANBOL-1387, i.e., using a client of the modified AIDA light framework. The workflow should be the following:

• The engine should work within any chain including NLP analysis engines. Those engines provide Text Annotations that have to be used as AIDA light disambiguation service parameter, which expects a list of mentions along with the original content as string

• Also, before using this disambuguation engine, an Entity Linking engine using the YAGO site is needed for later mapping the candidates returned by the AIDA light service with the entity annotations provided by the Entity Linking engine

• As response of the service, the disambiguation engine would get an ordered (by confidence) list of candidates (entities) identified by their URI in the YAGO dataset. Those candidates have then to be linked with actual entities in the Stanbol YAGO site as Entity Annotations, using the confidence value returned by AIDA-light for each candidate as the confidence value of the entity annotation
