Edit project settings

Overview

See the dedicated article to know how to access project settings and manage settings that are common to several project types. Settings that are specific of thesaurus projects are grouped in the tabs described below.

Languages

The Languages tab allows you to set the project languages and choose the favorite language between them.

If you check only one language, it will be automatically set as the favorite.

Thesaurus URI

The Thesaurus URI tab allows you to define the prefixes for the URIs of the thesaurus's concepts and the other parts that compose the URIs.

  • To add a new URI prefix, select Add new URI prefix and enter the new prefix.
  • To change an existing prefix, just select and edit it.
  • To delete an existing prefix, hover over it and select the trash bin icon .

  • If you have to use characters that are not allowed in an URI, like white spaces, hover over the prefix and select Encode URI to create an URL-encoded version of it.

    Note

    You can delete an existing prefix only if there is at least another prefix defined.

  • To determine the parts that constitute the full URL for a given prefix, select the prefix and then select the parts that can be:

    • Project name
    • Concept label plus optional concept ID

  • When done, select Save.

DataTypes

In this tab you can manage the data types that you can attribute to the individual values of the custom properties of a concept and choose the default data type.

  • Under Basic DataTypes are listed the value No DataType, to be selected if you want the value of a custom property to have no data type by default, and the data types taken from http://www.w3.org/2001/XMLSchema.
  • Under Custom DataTypes are listed the data types automatically taken from imported taxonomies or subtrees and any other user-defined data types.

To add a custom data type:

  1. Select Add new DataType. A new text box appears.
  2. Type the data type URL in the new text box. If you have to use characters that are not allowed in an URI, like white spaces, hover over the prefix and select Encode URI to create an URL-encoded version of it.
  3. Click anywhere in the dialog outside the text box.

To delete a custom data type, select the data type and then select the trash icon .

Select Save to commit the changes.

Extraction

The models generated during experiments extract the occurrences of the thesaurus concepts from documents. In the Extraction tab you find the settings that affect extraction and validation. These settings are used as default values for new concepts and can be overridden at the concept level.

Extraction method

Extraction method is the way generated models will use concepts' labels to determine the portions of text to extract.

Possible methods are:

  • Semantic: all the portions of text expressing the same meaning of the concept labels, in any inflected form. For example, if the label is sandglass, the model will extract sandglass, hourglass, sandglasses, hourglasses.
  • Base form: the label is considered as a lemma (the base form or dictionary entry for a term) and all the inflections of it are extracted. For example, if the label is sandglass the model will extract sandglass and sandglasses.
  • Exact label: the model will extract exact matches of the labels.

Approval status

In this panel you can set the default approval status for new concepts. See the article dedicated to the topic for further information.

Context settings

The context is the subdivision of the text or the sequence of subdivisions in which to search for the expressions of the concept to be extracted.

Warning

Not all parts of a text correspond to clauses. For example, a heading like:

Disclaimer

may not be considered a clause, so be aware that if you set Clause as context, there may be portions of the document text in which extraction will not take place.

The context also serves in combination with the specification of terms that must or must not co-occur in the vicinity of the term corresponding to the concept to be extracted. Co-occurrence constraints can be set at the concept level.

Suggestions

In the Suggestions tab you can check and set the settings that determine which suggestions are displayed when you edit a concept.
