What OpenEMPI is

OpenEMPI is paid entity-resolution and record-deduplication software that links duplicate records into trusted master records. Its customizable, domain-agnostic model can represent patient, provider, customer, business, and other records. Matching pipelines can combine deterministic, probabilistic, and artificial intelligence-based methods, using metrics such as Jaro–Winkler, Levenshtein, Soundex, and Double Metaphone. Processing supports both real-time and batch modes. Uncertain candidates can enter a review queue with confidence scores, merge or reject controls, and an audit trail. Integration options include a RESTful API, webhooks, HL7 v2/v3, and FHIR. A web Administrative Console configures and manages an instance. Documentation covers deployment on Unix/Linux and Windows, while server requests are audited and stored in the database. Platforms listed include API, Linux, self-hosted, web, and Windows. Pricing is available on request, and commercial support, SLAs, private resources, and custom modules are offered to licensed customers.
