Train a Binary Category

You can use the BinaryCatTrain action to train a binary category. Unlike normal categories, which have only positive training, binary categories can have both positive and negative training.

If the binary category has existing training, BinaryCatTrain adds the new training to it. If you want to replace the training for a binary category, you must first use the BinaryCatDeleteTraining action to delete the existing training. For example:,456&NegativeDocID=789,890

This action uses port 9020 to instruct the IDOL Category component, which is located on a machine with the IP address, to train the binary category named spam_binarycat. It uses the documents with IDs 123 and 456 for positive training, and the documents with IDs 789 and 890 for negative training.
