Claim 10:
11. The method according to claim 10, wherein the constructing the sentence vector of the segmented sentence further comprises:
determining a quantity of times of occurrence of a notional word in blockchain data historically transmitted to the content security device by a user node transmitting the blockchain data to the content security device as a first quantity of times of occurrence for each notional word obtained based on the word segmentation on the segmented sentence;
concatenating word vectors of a pre-determined quantity of notional words ranking at a top in descending order of first quantities of times of occurrence into the sentence vector of the segmented sentence based on the order of the notional words in the segmented sentence;
determining a quantity of times of occurrence of the notional word in blockchain data transmitted historically by all user nodes to the content security device as a second quantity of times of occurrence for each notional word obtained based on the word segmentation on the sentence in the sentence list; and
concatenating word vectors of a pre-determined quantity of notional words ranking at a top in descending order of second quantities of times of occurrence into the sentence vector of the sentence in the sentence list based on the order of the notional words in the sentence in the sentence list, the two pre-determined quantities being the same.
