We chose an initial training set T 1 of ∼5 sequences on CoNLL2000 and CoNLL2000POS datasets, ∼7 sequences on CoNLL2003 dataset and ∼4 sequences on NLPBA2004 dataset, for a total of ∼100 labeled tokens for each dataset.
after the choice of the most informative token the sets L i , U i and T i are updated.
