I am using the IBM Content Classification Classification Center. Is there an easy way for me to determine how much unclassified content still exists in my repository?
You can use the IBM Content Classification (previously known as IBM Classification Module or ICM) content extractor utility. The desired information about number of items to be classified returned by the query is displayed immediately after the extractor starts so there is no need to extract all items.
See the related information section below for a link to the documentation that explains how to use this utility.
