  2. Select the plus button on the main toolbar and then Thesaurus project.

Alternatively:

    • Select Thesaurus on the left menu, then select New Thesaurus project in the Create project area in the right column.

    Or:

    • Select New Thesaurus project in the Create item area.

The New Thesaurus project dialog will appear.

    Warning

    The Tech version cannot be changed once the project has been created.

  2. Select Create.

The creation wizard will start.

The project creation wizard

To quit the wizard at any step:

  • Select Exit wizard from the toolbar.

Or:

  • Select the expert.ai icon in the upper left corner of the page.

The Save changes dialog will appear.
Select:

  • Cancel to close the dialog.
  • Delete project to quit the wizard and delete the project.
  • Save to save the project and quit the wizard, so that the project can be opened from the main dashboard at a later time to complete the wizard.

Languages

In the first step of the wizard you choose the languages for your project.

  1. Select one or more languages. The first language you select is automatically marked as favorite . In case of multiple languages, select the star beside one of them if you want to make it the favorite.
  2. Select Next.

Settings

In the second step of the wizard you can check and change the default settings that will be applied to each new concept, with one exception: if in the next step of the wizard you import a SKOS definition from a file and it contains, for one or more of the defined concepts, one or more of these settings, the settings specified in the file will prevail over those set in this step.

The settings that can be checked and changed are those that influence the extraction of concepts—if users do experiments and generate models—and the default approval status.
To learn more about these settings see the article on editing the basic extraction settings for the single concept and the one dedicated to concept validation.
The settings set in this step become those of the project and can therefore be edited later.

  1. Check and possibly change the settings.
  2. Select Next.

Resources

In the third step of the wizard you start defining the thesaurus. You can always change it later.

You need to define at least one concept to start with.

  1. To enter concepts by hand, select Create project resources and Next: the Create Thesaurus dialog appears.
  2. Enter a label for a concept and press Enter.
  3. Repeat the step above if you want to define more concepts.
  4. Select Next when done.

Or:

  1. To import a SKOS definition from file, select Import Thesaurus.
  2. Browse the file system to locate and open the RDF/XML format file.
  3. Select Next.

Defined concepts are displayed in two panels, Resources and Edit concept, where you can edit them. In the Resources panel you can also create and manage sections, custom relations and custom properties. You can do it later, if needed, once the project has been created.
Select Next when done.

Library

In the fourth step of the wizard you create the default document library for the project.

Info

In thesaurus projects the training stuff for model generation is constituted by the thesaurus itself, so no training library is needed. Libraries are nevertheless useful to get automatic suggestions for new concepts and labels and also to test models.

You need to have at least one document in the library and you can add more later.

  1. Enter the library name in Library name or confirm the suggested name, then select Next.

  2. In Corpora and folders, select the sources for the library. You can select corpus projects or upload documents from the file system to create in-project corpora.

    You can use these tools to display and filter corpora:

    • The search bar to filter corpora by name. Your search must contain at least three characters.
    • Show table view to have corpora listed in a table. When in table view, you can sort items by selecting the desired column header.
    • Show card view to display corpora as cards. When in card view, select Share to share the corpora with other users.

    The information displayed for corpora is the same displayed in the Corpus info sub-panel of the main dashboard.

    Info

    Available corpus projects are only those based on the Tech version you selected before staring the wizard.

    To create an in-project corpus by uploading files, select Upload and proceed as explained in the article dedicated to the topic. When the upload is complete, the in-project corpus is listed along with the other corpora.

    When all the document sources are available, select them from the list.

  3. Select Next. The documents will be processed to create the library.

Summary

The last step of the wizard sums up project information and allows you to open the project.

Info

Thesaurus Quality is a measure of how much the default library covers defined concepts.

Select Open project to end the wizard and open the project.
