First claim

It is claimed:

1 . A method of recommending product information, comprising the steps of:
acquiring a product list comprising product information on at least one product from a server, wherein the product information comprises product names and price indexes and is associated with at least one product label; calculating a purchasing power index of a user and acquiring personalized labels of the user, wherein the personalized labels are a set of product labels that the user likes; generating a product recommendation list for the user according to the purchasing power index, the personalized labels, the product labels, and the price indexes, wherein product information in the product recommendation list is selected from the product list; and making a recommendation to the user based on the product recommendation list.

2 . The method according to claim 1 , wherein the step of generating the product recommendation list for the user according to the purchasing power index, the personalized labels, the product labels, and the price indexes comprises the steps of:
filtering the product information in the product list according to the purchasing power index and the price indexes to obtain a first set of results; filtering the first set of results according to the personalized labels and the product labels to obtain a second set of results; and generating the product recommendation list for the user according to the second set of results.

3 . The method according to claim 2 , wherein the step of filtering the product information in the product list according to the purchasing power index and the price indexes to obtain the first set of results comprises the steps of:
comparing the purchasing power index with the price indexes of the product information in the product list respectively; and if an absolute value of a difference between the purchasing power index and the price index is less than a first predetermined threshold, adding the product information which comprises the price index to the first set of results.

4 . The method according to claim 3 , wherein the production information further comprises recommendation scores, and wherein the step of filtering the first set of results according to the personalized labels and the product labels to obtain the second set of results comprises the steps of:
calculating liking probabilities of the user on respective product labels according to the personalized labels; calculating liking probabilities of the user on respective product information in the first set of results according to the liking probabilities of the user on the respective product labels; calculating user liking degree scores of respective product information in the first set of results according to the liking probabilities and the recommendation scores of the user for the respective product information in the first set of results; and adding the product information of which the user liking degree score exceeds a second predetermined threshold to the second set of results.

5 . The method according to claim 4 , the step of wherein generating the product recommendation list for the user according to the second set of results comprises the step of:
ranking the product information in the second set of results according to the user liking degree scores to generate the product recommendation list for the user.

6 . The method according to claim 1 , wherein the step of generating the product recommendation list for the user according to the purchasing power index, the personalized labels, the product labels, and the price indexes comprises the steps of:
filtering the product information in the product list according to the personalized labels and the product labels to obtain a third set of results; filtering the third set of results according to the purchasing power index and the price indexes to obtain a fourth set of results; and generating the product recommendation list for the user according to the fourth set of results.

7 . The method according to claim 6 , wherein the product information further comprises recommendation scores, and wherein the step of filtering the product information in the product list according to the personalized labels and the product labels to obtain the third set of results comprises the steps of:
calculating liking probabilities of the user on respective product labels according to the personalized labels; calculating liking probabilities of the user on respective product information in the product list according to the liking probabilities of the user on the respective product labels; calculating user liking degree scores of respective product information in the product list according to the liking probabilities and the recommendation scores of the user for the respective product information in the product list; and adding the product information of which the user liking degree score exceeds a second predetermined threshold to the third set of results.

8 . The method according to claim 7 , wherein the step of filtering the third set of results according to the purchasing power index and the price indexes to obtain the fourth set of results comprises the steps of:
comparing the purchasing power index with the price indexes of the product information in the third set of results respectively; and if an absolute value of a difference between the purchasing power index and the price index is less than a first predetermined threshold, adding the product information which comprises the price index to the fourth set of results.

9 . The method according to claim 7 , wherein the step of generating the product recommendation list for the user according to the fourth set of results comprises the step of:
ranking the product information in the fourth set of results according to the user liking degree scores to generate the product recommendation list for the user.

10 . The method according to claim 1 , wherein the step of calculating the purchasing power index of the user comprises the steps of:
acquiring price indexes and weights of respective types of products which have been purchased by the user; summing products of the price indexes and weights of the respective types of products which have been purchased by the user to obtain a first value; and dividing the first value by a sum of the weights of the respective types of products which have been purchased by the user to obtain the purchasing power index of the user.

11 . The method according to claim 1 , wherein after acquiring the product list, the method further comprises the steps of:
performing a balance processing on the price indexes using a logical distribution formula to obtain balanced price indexes; and generating the product recommendation list for the user according to the purchasing power index, the personalized labels, the product labels, and the balanced price indexes.

12 . An apparatus for recommending product information, comprising:
