Welcome to the manual of Platform NL Flow.

NL Flow is a Web application that allows you to create and manage workflows based on the text intelligence models you design with Platform authoring application or with Studio.
NL Flow is also the runtime hosting published workflows as Web resources that any program can request through a REST API to analyze documents.
Creating and publishing a workflow means making Platform and Studio models available in a production environment for practical use.

A workflow does not necessarily coincide with a model: it can be as simple as a single model or as complex as your analysis needs, with pre-processors and post-processors taken from those already available or written in a JavaScript-like language. It is also possible to design a workflow that uses more than one model, sequentially or in parallel.

This manual is divided into the following sections:

  • How-to guide: all the procedures for building, managing, publishing, making workflows accessible via API and manage accounts.
  • Reference guide: the description of all pre-defined building blocks (processors, operators, Knowledge Models), of the configuration parameters and of the input and output of all block types.
