Long text matching recognition method and device, electronic equipment and storage medium

The invention relates to an intelligent decision-making technology, and discloses a long text matching recognition method. The method comprises the following steps: constructing an initial matching decision-making tree by utilizing a long text training set, adding the decision-making tree to obtain an updated matching decision-making tree, and inputting the long text training set into the updated matching decision-making tree; calculating an objective function value of an updated matching decision tree by using the obtained predicted value set, adjusting or keeping the updated matching decision tree according to a judgment result of the objective function value and a target threshold value to obtain a standard matching decision tree, and inputting a to-be-judged reply text and a standard reply text into the standard matching decision tree to obtain a matching result. In addition, the invention also relates to a blockchain technology, and the objective function value can be stored in a node of a blockchain. Th
