wherein S is_nAn evaluation score, g, for the nth candidate hotel_nIs a target parameter matrix f_iLine feature vector, W, corresponding to the nth candidate hotel_iIs g_nThe combination weight omega corresponding to each element in the_iA collection of (a).

Finally, determining competing hotels of the target hotel to be selected from the candidate hotels based on the calculated evaluation value of each candidate hotel; specifically, the candidate hotel with the evaluation score larger than the preset evaluation threshold value can be determined as a competing hotel for the target hotel to be selected; or arranging a plurality of candidate hotels in a descending order according to the evaluation scores of the candidate hotels, and determining the candidate hotels with the preset digits as the competitive hotels to be selected from the target hotels.

In one embodiment, after determining a competing hotel from the plurality of candidate hotels based on the hotel score vector, the recommendation method further comprises: and determining a display hierarchy of each bidding hotel based on the evaluation score of each bidding hotel, and displaying each bidding hotel to the user according to the display hierarchy.

When a display instruction issued by a user is received, determining the display level of each competitive hotel according to the evaluation score of each competitive hotel, and further displaying each competitive hotel to the user one by one according to the display level. Here, the evaluation score of the competitive hotel refers to an evaluation score of a candidate hotel corresponding to the competitive hotel, where the display hierarchy may be preset, specifically, a score range corresponding to each hierarchy may be set, and when the evaluation score of the competitive hotel falls within the score range corresponding to the hierarchy, the hierarchy is determined as the display hierarchy of the competitive hotel.

In one embodiment, the display hierarchy for each competing hotel is determined by: determining an evaluation difference value between every two bidding hotels based on the evaluation score of each bidding hotel; determining a maximum evaluation difference value from the determined plurality of evaluation difference values and a maximum secondary evaluation difference value from the plurality of evaluation difference values, excluding the maximum evaluation difference value; determining a score range for each display level based on the maximum evaluation difference and the secondary evaluation difference; and determining the display hierarchy of each competitive hotel based on the evaluation score of each competitive hotel.

Here, in determining the display hierarchy of each competing hotel, first, an evaluation difference between each two competing hotels is determined, respectively; secondly, determining a maximum evaluation difference value from the plurality of determined evaluation difference values, and determining a maximum secondary evaluation difference value except the maximum evaluation difference value from the plurality of evaluation difference values; then, determining a score range covered by each display level according to the maximum evaluation difference value and the secondary evaluation difference value; and finally, when the evaluation score of one competitive hotel is within the score range of the display hierarchy, the competitive hotel is displayed in the display hierarchy.

As an example, assume that C₁，C₂，...，C_nFor n competing hotels ranked from high to low by score, there is a maximum evaluation difference absolute value of C_Sp(as the difference in hotel score at location p and hotel score at location p-1), and the absolute value of the secondary assessment difference is C_Sq(as the difference in hotel score for location qth and location q-1), where p, q ∈ [1, n ∈ ]]And grouping the hotels according to the sequence number, then:

the first layer of competing hotels is C₁，C₂，…C_min(p，q)-1

Second floor competing for hotel is C_min(p，q)，…C_max(p，q)-1

The third layer of competing hotels is C_max(p，q)，…C_n

It should be noted that, if only one competitive hotel, only 1 floor is displayed; if only two competing hotels are available, the first floor shows one hotel and the second floor shows one hotel.
