# Create an Expertise Profile for a User

Run the `ProfileUser` action when a user creates text (for example, a document in the IDOL Content component that was authored by a user, or text that a user enters in a help desk environment). The IDOL Community component analyzes the text that the user created, and determines if it is similar to any concepts in the existing expertise profile (using `MatchThreshold`).

If the content of the viewed text is similar to an existing expertise profile concept, Community updates the existing concept with the text (if several concepts are similar, only the most similar one updates). If the text is not similar to an existing expertise profile concept, Community creates a new concept in the expertise profile.

NOTE: Community uses only the five strongest concepts in a user expertise profile for expertise matching.

For example:

    http://12.3.4.56:4000/action=ProfileUser&UserName=Administrator&Document=The chemical structure of everyone's DNA is the same. The only difference between people (or any animal) is the order of the base pairs& MatchThreshold=60&NamedArea=Expertise

This action instructs the IDOL Community component to analyze the specified text. If the text has a conceptual relevance of at least 60 percent to any concept in the `Administrator` user expertise profiles, Community uses it to update the matching expertise profile concept (if several concepts are similar, only the most similar one updates). If the text does not have a conceptual relevance of at least 60 percent to an existing expertise profile concept, Community creates a new expertise profile concept from it.
