Embodiment 1
[0043] see figure 1 , figure 1 It is a schematic diagram of the information push process in Embodiment 1 of the present application. The specific steps are:
[0044] Step 101, acquire source item pool.
[0045] The source item pool here is equivalent to a seed item, which is used to find more similar items through these items.
[0046] In this step, the source item pool is obtained, including:
[0047] Get the source item pool for direct upload;
[0048] Or, select an item that matches the configured parameters from the platform item pool, and generate a source item pool.
[0049] That is to say, in the embodiment of this application, the source item pool directly uploaded by the user can be used, or a configuration page can be provided, and the user can configure parameters, such as item attributes, time of listing, item name, etc.; generate target items according to the configured parameters pool.
[0050] Step 102, acquiring a target item pool matching the configured...
Embodiment 2
[0089] In the first embodiment, the realization of determining items similar to items in the source item pool in the target item pool and generating a similar item pool is as follows:
[0090] see figure 2 , figure 2 It is a schematic flowchart of determining items similar to items in the source item pool in the target item pool in Embodiment 2 of the present application. The specific steps are:
[0091] Step 201, select the first item in the source item pool.
[0092] The first item here is any item in the source item pool.
[0093] Step 202, select a second item in the target item pool.
[0094] The second item here is any item in the target item pool.
[0095] Step 203, determining the attribute similarity between the first item and the second item.
[0096] The similarity is calculated according to the Jaccard similarity, the total number of items in the platform item pool and the number of platform items with attributes in the attribute intersection of the first i...
Embodiment 3
[0122] In the first embodiment, the realization of determining items similar to items in the source item pool in the target item pool and generating a similar item pool is as follows:
[0123] see Figure 4 , Figure 4 It is a schematic flowchart of determining items similar to items in the source item pool in the target item pool in Embodiment 3 of the present application. The specific steps are:
[0124] Step 401, select a third item in the source item pool, and obtain the title vector of the third item.
[0125] The third item is any item in the source item pool.
[0126] Step 402, select a fourth item in the target item pool, and obtain a title vector of the fourth item.
[0127] The fourth item is any item in the target item pool.
[0128] In the embodiment of the present application, the title vector of the title is obtained through a preset word vector model.
[0129] When there are multiple word vector models to be selected, in the embodiment of the present appli...
