Entity-fishing is a generic named-entity recognition and disambiguation module (NERD) deployed as a stable on-line service that demonstrates the possible delivery of sustainable technical services as part of the development of infrastructures for the humanities in Europe. In particular, the developments described here are intended to contribute not only to DARIAH, the European digital research infrastructure for the arts and humanities, but also to OPERAS, the European research infrastructure for the development of open scholarly communication in the social sciences and humanities. Deployed as part of the French national infrastructure Huma-Num, the service provides an efficient state-of-the-art implementation coupled with standardised interfaces that allow easy deployment in a variety of potential digital humanities contexts.
