Resorting product suggestions for a user interface

A non-transitory computer-readable medium having computer-executable instructions stored thereon that when executed by a processor causes the processor to perform steps comprising:

• receiving an identifier for a product together with an indication that a control on a web page has been selected by a user;
• updating a user vector for the user based on the selection of the control and the identifier for the product;
• scoring each product in a first list of products based in part on a similarity between a product vector for the product and the user vector for the user;
• removing a product from the first list of products that has a highest score;
• adding the product that has the highest score to a second list of products;
• for each product remaining in the first list of products, reducing the score of the product based on similarities between multiple dimensions of the product vector for the product and multiple dimensions of the product vector for the product added to the second list of products wherein a plurality of the multiple dimensions of each product vector represent respective tokens found on a respective web page for the respective product;
• wherein a first product and a second product are remaining in the first list of products and a product vector of the first product is more similar to the product vector for the product added to the second list than a product vector of the second product is to the product vector for the product added to the second list such that a respective score for the first and second product are both reduced with the score for the first product being reduced more than the score for the second product;
• and
• receiving a request from a client device for a list of recommended products and in response generating a user interface to display products in the second list of products wherein the user interface is limited to displaying a limited number of products and such that similar items in the second list of products are dispersed on the user interface among the limited number of products on the user interface.

A system comprising:

• a memory containing a respective multiple-dimension product vector for each of a plurality of products, wherein a plurality of the multiple dimensions represent respective tokens found on a respective web page for the respective product;
• a processor configured to:
• receiving an identifier for a product together with an indication that a control on a web page has been selected by a user;
• updating a user vector for the user based on the selection of the control and the identifier for the product;
• generating a first list of products by scoring each of the plurality of products based in part on a similarity between the product vector for the respective product and the user vector for the user;
• generate a second list of products from the first list of products by sequentially selecting products from the first list of products to add to the second list of products;
• wherein sequentially selecting products from the first list of products comprises selecting a product from the first list of products with a highest score, after selecting a product from the first list of products, removing the product from the first list of products, adding the product to the second list of products, and reducing the score of each product remaining in the first list of products based on a similarity between the respective product vector of each product in the first list of products and the product vector of the product removed from the first list of products such that a score for a first product in the first list of products and a score for a second product in the first list of products are both reduced with the score for the first product reduced more than the score for the second product, wherein the product vector for the first product is more similar to the product vector of the product removed from the first list than the product vector of the second product is to the product vector of the product removed from the first list;
• receive a request from a client device for a list of recommended products;
• and
• generate a user interface displaying a limited number of suggested products for a user where the limited number of products are taken from the products in the second list of products such that similar suggested products are dispersed on the user interface among the limited number of suggested products on the user interface.
