License Documentation Status


The documentation of entity-fishing is available here.

For upgrade from the previous version please check the upgrade guide.


entity-fishing performs the following tasks:

  • entity recognition and disambiguation against Wikidata and Wikipedia in a raw text or partially-annotated text segment, entity-fishing

  • entity recognition and disambiguation against Wikidata and Wikipedia at document level, for example a PDF with layout positioning and structure-aware annotations, entity-fishing

  • search query disambiguation (the short text mode) - bellow disambiguation of the search query "concrete pump sensor" in the service test console, Search query disambiguation

  • weighted term vector disambiguation (a term being a phrase), Search query disambiguation

  • interactive disambiguation in text editing mode.
    Editor with real time disambiguation

Current version

entity-fishing is a work-in-progress! Latest release version is 0.0.3.

This version supports English, French, German, Italian and Spanish, with an in-house Named Entity Recognizer for English and French. The knowledge base includes 37 million entities from Wikidata.

Runtime: on local machine (Intel Haswel i7-4790K CPU 4.00GHz - 8 cores - 16GB - SSD)

  • 800 pubmed abstracts (172 787 tokens) processed in 126s with 1 client (1371 tokens/s)

  • 4800 pubmed abstracts (1 036 722 tokens) processed in 216s with 6 concurrent clients (4800 tokens/s)

  • 136 PDF (3443 pages, 1 422 943 tokens) processed in 1284s with 1 client (2.6 pages/s, 1108.2 tokens/s)

  • 816 PDF (20658 pages, 8 537 658 tokens) processed in 2094s with 6 concurrent clients (9.86 pages/s, 4077 tokens/s)

Accuracy: f-score for disambiguation only between 76.5 and 89.1 on standard datasets (ACE2004, AIDA-CONLL-testb, AQUAINT, MSNBC) - to be improved in the next versions.

The knowledge base contains more than 1 billion objects, not far from 15 millions word and entity embeddings, however entity-fishing will work with 3-4 GB RAM memory after a 15 second start-up for the server (but please use SSD!).

Have a look at our presentation at WikiDataCon 2017 for some design and implementation descriptions.
