Key phrase content classifiers

The presence of a keyword or phrase (such as “Top Secret” or “Project X”) in a web post may indicate that classified information is being leaked. You can learn about activity like this by defining a key phrase classifier.

To create a key phrase classifier, complete the fields as follows:

Field	Description
Name	Enter a name for this key phrase classifier.
Description	Enter a description for this key phrase.
Key phrase	Enter the key word or phrase that might indicate classified information, up to 255 characters. Key phrases are not case sensitive. Leading and trailing white spaces are ignored. If you need to use slashes, tabs, hyphens, underscores, or carriage returns, define a regular expression classifier rather than a key word classifier.

Key phrase

Enter the key word or phrase that might indicate classified information, up to 255 characters. Key phrases are not case sensitive.

Leading and trailing white spaces are ignored. If you need to use slashes, tabs, hyphens, underscores, or carriage returns, define a regular expression classifier rather than a key word classifier.

Unlike dictionaries, key phrases also identify partial matches. For example, the key phrase “uri” reports a match for “security”.
