# Create an Interest Profile for a User

Run the `ProfileUser` action when a user views a document. The IDOL Community component analyzes the document that the user is viewing, and determines if it is similar to any of the concepts in their interest profile (using `MatchThreshold`).

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

NOTE: Community uses only the five strongest concepts in a user interest profile for recommendations, alerting, and similar user matching.

For example:

    http://12.3.4.56:4000/action=ProfileUser&UserName=Administrator&Document=3422+5776&MatchThreshold=60&NamedArea=Interest

This action instructs the IDOL Community component to analyze the content in the `3422` and `5776` documents. If the content has a conceptual relevance of at least 60 percent to a concept in the interest profile of the `Administrator` user, Community uses it to update the matching interest profile concept (if several concepts are similar, only the most similar one updates). If the document content does not have a conceptual relevance of at least 60 percent to an existing interest profile concept, Community creates a new interest profile concept from it.
