Data element evaluation method and device, computer equipment and storage medium

The invention relates to a data element evaluation method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring data element field information, and determining a data element vector according to the data element field information; writing the data element segmented words and the data element vectors into a block chain, performing similarity comparison on the data element vectors and historical data vectors in the block chain, determining data element similarities, and determining a target vector set according to the data element similarities; determining a target attribute value weight of the target vector set according to the data element similarity and transaction contract data corresponding to the target vector set; and determining a data element evaluation attribute value according to the original attribute value of the target vector set, the target attribute value weight and the attribute value reference coefficient. According to the method, effective gu
