Latest commit 8eab57d Oct 9, 2019

A picture is worth a thousand words. Or is it? Tables, charts, pictures are all useful in undestanding our data but often we need a description; a story to tell us what are we looking at. Accelerated Text is a natural language generation tool which allows you to define data descriptions and then generates multiple versions of those descriptions varying in wording and structure.


Accelerated Text can work with all sorts of data:

  • descriptions of business metrics,
  • metadata describing interactions with the customers,
  • product attributes,
  • financial metrics.

Based on it will generate text to be used in business reports, e-commerce platforms or your customer support system.

Accelerated Text provides a web based Document Plan builder, where

  • the logical structure of the document is defined,
  • communication goals are expresed,
  • data usage within a text is defined.

Document Plans and the connected data are used by Accelerated Text's Natural Language Generation engine to produce multiple variations of the text exactly exactly expressing what was intended to bo communicated to the readers.


Whereof one cannot speak thereof one must be silent
-- Wittgenstein

Natural language generation is a broad domain with applications in chat-bots, story generation, and data description to name a few. Accelerated Text focuses on applying NLG technology to solve your "data to text" needs.

Data descriptions require precision. For example, a text describing weather conditions can not invent things beyond what it was provided: Temperature: -1C, Humidity: 40%, Wind: 10km/h. A generated text can only state those facts. The expression of an individual fact - temperature - could vary. It could result in a "it is cold", or "it is just below freezing", or "-1C" but this fact will be stated because it is in the data. A "data to text" system is also not one to elaborate on a story about the serenity of the freezing lake - again, it was not in the supplied data.

Accelerated Text follows the principle of this strict adherence to the data-bound text generation. Via its user interface it provides instruments to define how the data should be translated into descriptive text. This description - a document plan - is executed by its natural language generation engine to produce texts that vary in structure and wording but are always and only about the data provided.

Key Features

  • Document plan editor to define what needs to be said about the data.
  • Data samples can be uploaded as CSV files to be used when building Document Plans.
  • Text structure variations to provide richer reading experience going beyond rigid template generated text.
  • Vocabulary control to match the language style of each of your reader groups.
  • Build-in rule engine to allow the control of what is said based on the different values of the data points.
  • Live preview to see variations of generated text.

Getting Started


If you want to start tinkering and run it based on the latest code in the repository, first make sure that you have make installed

Then clone the project and run

make run-dev-env

After running this command the front-end will be availabe at the http://localhost:8080

The generation back-end API is at http://localhost:3001


Follow the step by step guide bellow to create a very simple document plan which generates book authorship sentences.

View Step
Firstly a new document plan has to be created. The application starts with a Create Plan button in its workspace.
You get an initial empty plan.
You'll need to select a CSV file to provide data for the natural language generation. Select a books.csv file.
The central part of the plan is the Abstract Meaning Representation element which defines the message to be communicated. Select Author from the AMR section.
Then we need to select from where in our book store data we'll have the Author field.
Same for Title field.
That's it, the plan is ready and should look like in the picture to the right.
Text Analysis section shows text variations generated by the natural language generation engine.


To get started with a development environment for Accelerated Text please follow the instructions in our developer's guides for the front-end and the text generation engine.
