Abstract

A multimode video merchandiser system utilizes two levels of inductive learning to derive rules for selecting the sequence in which images of products stored on a videodisc are presented on a video monitor to a user. The first level of inductive learning generates rules from market survey based, consumer profile attributes assigned to items selected by previous users to determine the profile of the consumer most likely to be using the system at any given time, and to present the items in a sequence most likely to appeal to such a user. The second level of inductive learning utilizes a set of product characteristic attributes assigned to items selected by the current user to determine that user'"'"'s preferences, and to modify the sequence of presentation to display first those items possessing the preferred characteristics.

means for presenting a visual display of said items in said selected sequence;

means for a user to generate a user input in response to the visual display of a particular item; and

means for rearranging said selected sequence based upon the assigned attributes of the particular items for which the user input was generated.

2. A method of controlling a video system with a programmed digital computer to display to users in a controllable sequence images of a plurality of items, said method comprising the steps of:

generating an attribute file containing as to each item an assigned value for at least one selected attribute;

establishing a list of said items sorted in the sequence to be presented by the video system based upon the assigned values of said at least one attribute;

controlling said video system to display said items in the order of said list;

providing means for users to generate inputs indicating interest in selected displayed items;

generating a data file containing as to each user input the item selected and a recurring time period during which the input was generated;

determining from the attribute file the assigned value of said at least one attribute for each of the selected items in the data file;

determining from the recurring time periods of the inputs and the assigned values of said at least one attribute for the selected items the most frequent value of said at least one attribute during each recurring time period;

as to the current time period, determining as to each item the match between the assigned value of said at least one attribute and the most frequent value of said at least one attribute during that time period; and

resorting said list of items in descending order of said match between the assigned value and the most frequent value during the current time period of said attribute, whereby the sequence in which said items are displayed changes in accordance with the responses of users during the respective time periods.

3. The method of claim 2 wherein the step of determining the most frequent value of said at least one attribute comprises generating a rule from the recurring time periods in which the inputs are generated and the values of said attributes assigned to the selected items, and which rule groups together recurring time periods in which the most frequent values of said at least one attribute are the same.

4. The method of claim 3 wherein the step of generating said attribute file comprises generating such a file containing as to each item an ordered group of assigned values for said at least one attribute, wherein said step of determining the most frequent value of said at least one attribute during each recurring time period utilizes the highest order value of said attribute for the selected items, and wherein said matching step takes into account the order in which the most frequent value is assigned to said attribute for each item.

5. The method of claim 4 wherein each ordered value of each attribute for each item is assigned a numerical score, wherein the matching step comprises determining as to each item the numerical score assigned to the most frequent value of the attribute during the current time period, and wherein the resorting step comprises arranging the items in order of the numerical score of the most frequent value of the attribute for the current recurring time period.

6. A method of controlling a video system with a programmed digital computer to display to users in a controllable sequence images of a plurality of items, said method comprising the steps of:

generating an attribute file containing as to each item an assigned value for each of a plurality of attributes;

establishing a list of said items sorted in a sequence to be presented by the video system based upon the assigned values of said attributes;

controlling said video recorder to display said items in the order of said list;

providing means for users to generate inputs indicating interest in selected items;

generating a data file containing as to each user input the item selected and a recurring time period during which the input was generated;

determining from the attribute file the assigned value of each of said attributes for each of the selected items in the data file;

as to each of said attributes determining from the recurring time periods of the inputs and the assigned values of that attribute for each of the selected items, the most frequent value of that attribute during each recurring time period;

as to the current time period, determining as to each item the match between the assigned values of said attributes and the most frequent values of those attributes during that time period; and

resorting said list of items in descending order of said match between the assigned values of the most frequent values during the current time period of said attributes, whereby the sequence in which said items are displayed changes in accordance with responses of users during respective time periods.

7. The method of claim 6 wherein the step of generating said attribute file comprises generating such a file containing as to each attribute for each item an ordered number of assigned values for said attribute, wherein said step of determining the most frequent value of each attribute during each recurring time period utilizes the highest ordered value of the attribute for the selected items, and wherein said matching step takes into account the order in which the most frequent value is assigned to that attribute for that item.

8. The method of claim 7 wherein each ordered value of each attribute for each item is assigned a numerical score, wherein the matching step includes determining for each item the sum of the numerical scores assigned to the most frequent value for all of the attributes, and wherein the step of resorting the items comprises rearranging the list in order of said sums of the numerical scores for each of the items.

9. The method of claim 8 wherein the step of determining the most frequent value of each of said attributes comprises generating a decision tree from the recurring time periods in which the inputs are generated and the highest ordered value of that attribute assigned to the selected items, said decision tree grouping together recurring time periods in which the most frequent value of each of said attributes are the same.

10. The method of claim 6 wherein said attributes are user profile attributes and wherein said resorting step in only carried out between users, said method further including generating an item characteristic file containing at least one item characteristic for at least some of said items, determining the item characteristics which occur the most times in items selected by the current user, and for said current user, revising said list to move the items assigned the item characteristics which occur most to the top of said resorted list.

11. A system for sequentially displaying to a number of successive users merchandise items to which a plurality of attribute values indicative of the appeal of the item to selected classifications of users during a plurality of recurring time periods have been assigned, said system comprising:

a video recorder in which images of said items are stored;

a video monitor on which said stored images are selectively displayed;

interface means by which users generate inputs identifying displayed items in which they are interested; and

a digital computer programmed;

to record the items identified by the inputs and a recurring time period during which each input was generated, to apply an inductive learning algorithm to the attribute values of the selected items to determine the most likely attribute values of items selected by users during each of said recurring time periods, and to select the sequence in which the images stored in the video recorder are displayed on said video monitor in descending order of a match between the attribute values assigned to each item and said most likely attribute values for the current recurring time period.

12. The system of claim 11 wherein said merchandise items are also assigned item characteristics and wherein said computer is programmed to apply a first inductive learning algorithm to said attribute values of items identified by inputs by all users only between inputs by separate users, to apply a second inductive learning algorithm to said item characteristics assigned to items selected by the current user to determine the item characteristics most appealing to the current user, and to adjust said selected sequence in which the items are displayed to the current user only, to present first to the current user items assigned the item characteristics most appealing to the current user.

13. A computer based method for sequentially presenting on a video monitor, images of items stored in a video recorder, comprising the steps of:
