In sequence labelling, when the label of a token in the sequence is changed, the output probability of the other tokens in the same sequence would also change. We propose a new active learning framework for sequence labelling which take the change of probability into account. At each iteration of the proposed method, every time the human annotator manually annotates a token, the output probabilities of the other tokens in the sequence are re-estimated. This proposed method is expected to reduce the amount of human annotation required for obtaining a high labelling performance. Through experiments on the NP chunking dataset provided by CoNLL, we empirically show that the proposed method works well.
