Also , advanced methods often require many training iterations , for example active learning ( Dagan and Engelson ,1995 ) and co-training ( Blum and Mitchell , 1998 ) .

Efficient training is required because the amount of data available for training will increase significantly . Also , advanced methods often require many training iterations , for example active learning ( Dagan and Engelson ,1995 ) and co-training ( Blum and Mitchell , 1998 ) . Processing text needs to be extremely efficient since many new applications will require very large quantities of text to be processed or many smaller quantities of text to be processed very quickly .
