CategorizeDocument

The CategorizeDocument processor makes requests (action=CategorySuggestFromText and action=BinaryCatQuery) to a Category component, to categorize incoming documents based on their text content.

For each matching category, the processor writes a new field to the document metadata:

<Category>
    <Name>...</Name>
    <Weight>...</Weight>
</Category>

The processor has an advanced configuration interface that you can use to:

• list, add, and modify binary categories
• list, add, and modify categories
• categorize text, for testing purposes

For more information about categorization, refer to the Knowledge Discovery Administration Guide.
