Make experiments in thesaurus projects

Overview

During an experiment you train a model for your thesaurus project and have it automatically tested against a library. Generated models can then be published to NL Flow.

Start an experiment

To start an experiment:

  1. In the upper bar, select Start an experiment .

  2. (Optional) Enter a name for the experiment. If you don't, the system will automatically assign a name.

  3. Select the test library in the Test library drop-down menu.
  4. Select Next: a wizard will start.

The steps of the wizards are used to set all the parameters of the experiment before starting it. In the reference section of this manual you will find the description of all the parameters.

Advanced parameters can be hidden by selecting Hide advanced parameters. When the checkbox is selected, the steps of the wizard that deal exclusively with advanced parameters are skipped.

After completing each step of the wizard, select Next to go on or Back to return to the previous step.
