Train Categories
 
NOTE You need to train only categories that you create with the CategoryCreate action. Categories that you create or import using another action are already trained. However, you can retrain them.
You can use the CategorySetTraining action to train a category. Category training can consist of text, documents, a Boolean expression and category content or a combination of these. These elements identify text, documents, agents, profiles and other categories that match the category. For example:
http://IDOLhost:port/action=CategorySetTraining&Category=323499876022105571056&DocID=238,785,9912&BuildNow=true
In this example, IDOL server trains the category with the ID 323499876022105571056 using the content of the documents with the ID 238, 785, and 9912. The BuildNow parameter instructs IDOL server to build the categories immediately, so they become active. You can also activate the category later using the CategoryBuild action.
