Abstract

An executing electronic arrangement for producing foodstuff recommendations and facilitating shopping in grocery stores, includes semantic context management entity configured to maintain semantic context-defining user information relative to a plurality of users, which indicates user preferences relative to groceries based on obtained explicit or implicit preference information, a base item recommendation entity configured to determine, for a first user, a plurality of more generic grocery recommendations based on the semantic context of the first user and the semantic contexts of a number of other users considered as neighbors to the first user according to predetermined similarity criteria, and a product recommendation entity configured to derive, for the first user, a shopping list incorporating a plurality of recommended products relative to a predetermined store offering such products, representing more specific instances of the determined more generic grocery recommendations and being derived utilizing knowledge of the store'"'"'s product range or current stock.

Claims

1. An electronic arrangement (104, 110, 110a) for producing foodstuff recommendations and thus facilitating shopping in grocery stores and the like, said arrangement comprising a number of computer apparatuses, such as at least one server device, said arrangement comprising:

a semantic context management entity (118, 203) configured to maintain semantic context-defining user information relative to a plurality of users, wherein said user information indicates user preferences relative to groceries based on obtained explicit or implicit preference information,

a base item recommendation entity (120, 204-214) configured to determine, for a first user, a plurality of more generic grocery recommendations (302, 302a) based on the semantic context of the first user and the semantic contexts of a number, preferably a plurality, of other users considered as neighbors to the first user according to predetermined similarity criteria, and

a product recommendation entity (122, 217, 218) configured to derive, for the first user, a shopping list (219, 308) incorporating a plurality of recommended products (306a) relative to a predetermined, optionally user-selected, store (105) offering such products, the recommended products representing more specific instances of the determined more generic grocery recommendations and being derived utilizing knowledge of the store'"'"'s product range or current stock (216, 304) as well as of the semantic context of the first user and preferably of said plurality of neighboring other users.

2. The arrangement of claim 1, configured to maintain semantic-context defining user information indicative of user preferences utilizing a dynamic feature vector preferably comprising a number of weighted attribute tags associated with products or more generic base items.

3. The arrangement of claim 2, configured, in response to positive preference information obtained relative to a product, to increase the associated weight of the product or corresponding more generic base item.

4. The arrangement of claim 1, configured to put higher weight on more recent user information than older user information (204).

5. The arrangement of claim 1, configured to maintain user information based on at least one obtained information element selected from the group consisting of:

behavioral data, purchase history data, feedback data relative to a shopping list, feedback data relative to a recommended product, feedback data relative to a recommended more generic base item, purchase history data, preference information relative to base items, preference information relative to products, user-defined allergy information or other restriction information, user-defined dislike information, product consumption history data, base item consumption history data, preferred recipe data, family data, family size, preference data relative to price, preference data relative to fat percentage, preference data relative to energy amount, preference data relative to nutrients, preference data relative to sugar, and preference data relative to product brands.

6. The arrangement of claim 1, configured to determine said plurality of more generic grocery recommendations through establishing indications of related purchase probabilities (211), wherein the purchase history of the first user and preferably of said plurality of other users is advantageously applied (207-210) in determining the indications, and further wherein statistical pattern matching, classification or HMM (Hidden Markov Model) is optionally utilized.

7. The arrangement of claim 1, configured to determine said plurality of other users neighboring the first user through utilization of Pearson correlation coefficient as a similarity criterion (206, 207).

8. The arrangement of claim 1, configured to establish said plurality of more generic grocery recommendations or the shopping list of more specific products as collaborative recommendation in view of a group of users, such as a family, the structure of which has been input to the arrangement.

9. The arrangement of claim 1, configured to derive the products for the shopping list based on electronically organized product detail information (215), optionally accessed or obtained via an external product repository such as GS1 or SA2 WorldSync.

10. The arrangement of claim 1, configured to receive user input and adapt the shopping list based thereon, optionally by removing a recommended product therefrom, adding a new product therein or including a user note therein.

11. The arrangement of claim 1, configured to provide a feedback UI (user interface) feature to the users regarding the recommended products or shopping list in general, optionally applying at least ternary logic with substantially positive, negative and at least one, more indefinite, voting options.

12. The arrangement of claim 1, configured to determine product relevancy indications (217) for a larger number of products from the standpoint of the first user in order to derive said shopping list incorporating said plurality of recommended products, optionally further configured to apply user reliability information for product relevancy determination.

13. The arrangement of claim 1, configured to introduce a new item in the shopping list randomly or pseudo-randomly (214) optionally based on information regarding the sale products available in the store.

14. The arrangement of claim 1, wherein different products are mutually distinguished utilizing distinct product identifiers, optionally EAN (International Article Number) or GTIN (Global Trade Item Number).

15. The arrangement of claim 1, configured to adapt the relevance of a more generic grocery recommendation through utilization of at least one temporal adjusting factor (208, 212) selected from a group consisting of:

instant of last purchase, estimated purchase frequency and estimated consumption time.

16. The arrangement of claim 1, configured to apply position data, such as network-based or satellite-based positioning data, regarding the first user to select the store for shopping list generation based on the more generic grocery recommendations.

17. The arrangement of claim 1, configured to apply user input, such as dynamic input or user-adjusted settings, to select the store.

18. The arrangement of claim 1, configured to apply a predetermined area such as the area defined by a predetermined radius around user-related location, such as home location, to determine the store.

19. A method for automated generation of a grocery shopping list to be performed by an electronic apparatus or a plurality of at least functionally connected electronic apparatuses, comprising:

obtaining and maintaining (201, 202, 222, 203, 220) semantic context-defining user information relative to a plurality of users, wherein said user information indicates user preferences relative to groceries based on obtained explicit or implicit preference information, such as allergy information input by a user or behavioral data like purchase history information obtained relative to the user,

determining, for a first user, a plurality of more generic grocery recommendations based on the semantic context of the first user and the semantic contexts of a number of other users considered as neighboring the first user according to predetermined similarity criteria (204-213),

selecting a grocery store according to a number of predetermined selection rules or user input,

constructing, for the first user, an initial shopping list incorporating a plurality of recommended products, the recommended products representing the more specific instances of the determined more generic grocery recommendations and being derived utilizing knowledge of the store'"'"'s product range or current stock, as well as of the semantic context of the first user and preferably of said plurality of other users (215-219), and

indicating said initial shopping list (308) to the first user for review, modification and/or acceptance preferably via the UI (user interface) of an associated service application.

20. A computer program comprising code means adapted, when run on a computer, to execute the method items of claim 19.
