NLP Flow

NLP Flow complements the standard Apache NiFi cross-platform data flow application with custom processors for creating powerful natural language processing pipelines.

With NLP Flow you can create pipelines to process unstructured natural language text. These pipelines can facilitate the ingestion and processing and text. For instance, text can be ingested from a file system, processed through entity extraction, and the resulting entities can be persisted to a database for analysis. Getting started instructions are available in the Quick Start.
