Abstract:
    The invention disclose method, system and device of purifying Bayesian negative sample to resolve the problem which can not automatic adjust the proportion imbalance state between the number of negative sample in Bayesian negative sample and the number of positive sample in Bayesian positive sample. The invention includes steps: after current network information is judged to be negative samples, the current network information is classified to the corresponding categories of negative samples and statistic the number of negative sample in the current category. If the number of the negative sample in current network information is not greater than the predetermined threshold value, the content in the current network information will be recorded to the Bayesian negative samples, otherwise, the current network information not handle.
