A super-fast in-process lookup service for canonical names, backed by tantivy.
juditha exists to tame the noise that follows from Named Entity Recognition: given a huge list of known names (company registries, persons of interest, sanctions lists), it tells you whether a span produced by your NER pipeline corresponds to one of them, even when the casing, accents, token order, or spelling differs.
The implementation uses a pre-populated names database and index. Data is either FollowTheMoney entities or simply list of names.
juditha is an in-process library first, but the read-only half of the store can be served over gRPC so several workers share one built corpus:
JUDITHA_URI=/var/lib/juditha juditha serve --host 0.0.0.0Clients just point JUDITHA_URI at it, and lookup / extract / percolate go over the wire unchanged:
JUDITHA_URI=grpc://localhost:50051 juditha lookup "Jane Doe"There is no authentication, so keep it on a private network. Docker image: ghcr.io/dataresearchcenter/juditha, mount a built store at /data.

Juditha Dommer was the daughter of a coppersmith and raised seven children, while her husband Johann Pachelbel wrote a canon.
To mark the compatibility with followthemoney, juditha follows the same major version, which is currently 4.x.x.
