Embodiment Construction
[0029] Such as image 3 As shown, the meta-learning method for alleviating the cold start problem of the recommended user by information enhancement in this embodiment is carried out in the following steps:
[0030] Step 1. Obtain the user's comment text on the item, and use the behavior of the user to comment on the item as the basis for linking the user and the item. This basis is also referred to as the comment relationship between the user and the item. According to all users, items and their comments relationship, constructing a user-item interaction bipartite graph such as figure 1 As shown, the specific process is as follows:
[0031] Step 1.1, according to the user set U of all users, U={u 1 ,u 2 ,...,u q ,...,u m}, where u q ∈U, q=1,2,...,m, representing different users, and all item sets I, I={i 1 ,i 2 ,...,i v ,...,i n}, where i v ∈I, v=1, 2,..., n represent different items, construct the adjacency matrix of users and items based on the comment relationsh...
