Entity disambiguation

entity-fishing is an open source tool dedicated to the automatic identification and disambiguation of Wikidata entities in multilingual text and PDF documents. The tool is based on machine-learning techniques (Gradient Tree Boosting, CRF, embeddings) exploiting Wikipedia as training source.

entity-fishing offers high performance, scalability and is totally generic in term of domains and languages. It can thus address a large variety of usages. Our usage focuses more particularly on processing technical and scientific documents, taking advantage of the massive amount of scientific knowledge and links present in Wikidata.

Browser-based PDF document annotation

The tool also performs of structure-aware annotations of PDF documents (with dynamic annotation layer over the PDF), thanks to the integration with GROBID.



With more than 38 million entities and 350 million statements, Wikidata is by far the largest Open and reusable Knowledge Base today available.

It is also a remarkable hub of scientific knowledge, containing for instance half a million genes (including the whole human genome) or more than 10 million scientific article records. In addition, Wikidata is interfacing many authoritative large scales external scientific Knowledge Bases via external identifiers.

entity-fishing makes available this vast amount of knowledge in text, using specialized entity mention recognizers for scientific terms in addition to the whole Wikipedia vocabulary and disambiguation techniques exploiting the available context where the mentions occur.
