Introduction

Welcome to the manual of expert.ai Platform NL Flow.

NL Flow is part of expert.ai Platform and is the Web application where a team of users creates and manages workflows based on the NLU models designed with Platform's authoring application or with expert.ai Studio.
NL Flow also includes the runtime components that host published workflows as Web resources that any program can request through a simple REST API to analyze documents.

Creating and publishing a workflow means making NLU models available in a production environment for practical use.

A workflow does not necessarily coincide with an NLU 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 possible include more models, used sequentially or in parallel.

It is even possible to have multiple, independent, flows in the same workflow: all the flows receive the same input and the overall output of the workflow is the concatenation of the output of the individual flows.

This manual has two sections:

  • How-to guide: all the procedures for managing workflows and user accounts.
  • Reference guide: the description of workflow building blocks.
