To create or edit a pattern

1. At the left of the Veritas Information Classifier, click Patterns.

2. Do one of the following:

   • To create a pattern, click New.

   • To edit an existing pattern, select it and then click Edit.

3. Set the fields as follows:

   Name	Specifies the pattern name. The name must be unique, and it can contain up to 100 alphanumeric, space, and special characters.
   Description	(Optional.) Provides a short description of the pattern for display in the Veritas Information Classifier.
   Type	Specifies the pattern type. For a Text or Regular expression pattern, you must specify the value for which to look. The same guidelines that you must observe when you enter these values in a policy condition apply when you enter them as a pattern value. See About policy conditions Choose Similar document to find items that resemble a supplied template. For example, you can find completed forms by submitting the blank form as a template. Unlike Text and Regular expression patterns, you can set the required confidence levels for Similar document patterns when you incorporate them in a policy condition. The document similarity feature can find instances where users have created variants of the template document by adding, removing, or reordering paragraphs, sentences, or words. It can also find instances where users have changed individual words. However, the more extensive these word changes are, the less likely the Veritas Information Classifier is to find a match. You must choose the required similarity mode: Full or Section. In Full mode, the Veritas Information Classifier compares the template document in its entirety with other documents in their entirety. This mode is useful when looking for instances where users have altered the template document in places without greatly affecting its overall size. In Section mode, the Veritas Information Classifier looks for instances where the content of the template document appears as one section within a larger document. To submit the template document, click Browse and then select the required document.

4. Test the pattern by clicking Browse and then choosing a document that ought to match it.

   After a few moments, the Veritas Information Classifier indicates whether it has found a match. When this is the case, you can click Show details to see the matching text and confidence levels.

5. Click Save.
