Embodiment approach
[0096] As an optional implementation mode of the embodiment of the present invention, such as image 3 As shown, for the above step S104, the embodiment of the present invention provides an implementation manner of determining the recommendation result, which may include:
[0097] S1041. Sorting the similarities in descending order to obtain a sequence of similarities.
[0098] S1042. Use the second nodes corresponding to the first preset number of similarities in the similarity sequence as each target second node.
[0099] S1043. Recommend each target second node to the first node.
[0100] The calculated similarities between the second feature vector corresponding to the first node and the second feature vectors corresponding to each second node are sorted in descending order to obtain a similarity sequence. Furthermore, the second nodes corresponding to the previous preset number of similarities in the similarity sequence are determined as the target second nodes, and eac...
