Time-decay analysis of a photo collection for automated item listing generation

1. A method comprising:

receiving image data from a mobile device;

identifying, based on the image data, an item and a product characteristic of the item;

generating listing data of the item based on the product characteristic;

determining that the item is associated with a product category;

identifying a set of listings associated with the product category;

applying a decay formula to the set of listings to generate a discounted number of sales and a discounted number of impressions for at least one listing of the set of listings;

determining a ratio of the discounted number of sales to the discounted number of impressions;

determining a ranking of the set of listings based on the ratio;

generating a price estimate of the item based on the ranking of the set of listings and the ratio of the discounted number of sales to the discounted number of impressions; and

causing display, by a computing device, of a user interface that includes a user selectable user interface (UI) element associated with a request to list the item, the request including the listing data and the price estimate of the item.

2. The method of claim 1 , further comprising:

receiving an indication of user selection of the user selectable UI element associated with the request; and

listing the item on a network-based publication system.

3. The method of claim 1 , wherein the image data comprises an image or a video captured by a camera of the mobile device.

4. The method of claim 3 , wherein determining that the item is associated with a product category includes selecting the product category from a plurality of categories, the plurality of categories being arranged as a hierarchy of categories.

5. The method of claim 1 , wherein:

the item is a first item, and

the method further comprises:

identifying, at a predetermined time interval, a second item from a second image based on the image data.

6. The method of claim 5 , wherein the second item is represented in a bar code, the bar code being utilized to generate listing data of the second item.

7. The method of claim 5 , further comprising:

batch-listing the first item and the second item to a network-based publication system.

8. The method of claim 7 , wherein batch-listing the first item and the second item to a network-based publication system further comprise:

generating a first listing for the first item;

generating a second listing for the second item; and

simultaneously uploading the first listing and the second listing to the network-based publication system.

9. The method of claim 1 , further comprising:

causing display of a message on the user interface, the message including a question inviting a user response to confirm if the image represents the item.

10. The method of claim 1 , further comprising:

tagging the item with metadata associated with the product category.

11. A system comprising:

at least one processor; and

executable instructions accessible on a computer-readable medium that, when executed, cause the at least one processor to perform operations comprising:

receiving image data from a mobile device;

identifying, based on the image data, an item and a product characteristic of the item;

generating listing data of the item based on the product characteristic;

determining that the item is associated with a product category;

identifying a set of listings associated with the product category;

applying a decay formula to the set of listings to generate a discounted number of sales and a discounted number of impressions for at least one listing of the set of listings;

determining a ratio of the discounted number of sales to the discounted number of impressions;

determining a ranking of the set of listings based on the ratio;

generating a price estimate of the item based on the ranking of the set of listings and the ratio of the discounted number of sales to the discounted number of impressions; and

causing display, by a computing device, of a user interface that includes a user selectable user interface (UI) element associated with a request to list the item, the request including the listing data and the price estimate of the item.

12. The system of claim 11 , wherein the operations further comprise:

receiving an indication of user selection of the user selectable UI element associated with the request; and

listing the item on a network-based publication system.

13. The system of claim 11 , wherein the image data comprises an image or a video captured by a camera of the mobile device.

14. The system of claim 13 , wherein the operation of determining that the item is associated with a product category includes selecting the product category from a plurality of categories, the plurality of categories being arranged as a hierarchy of categories.

15. The system of claim 11 , wherein the item is a first item, wherein the operations further comprise:

identifying, at a predetermined time interval, a second item from a second image based on the image data.

16. The system of claim 15 , wherein the second item is represented in a bar code, the bar code being utilized to generate listing data of the second item.

17. The system of claim 15 , wherein the operations further comprise:

batch-listing the first item and the second item to a network-based publication system.

18. The system of claim 17 , wherein the operation of batch-listing the first item and the second item to a network-based publication system further comprise:

generating a first listing for the first item;

generating a second listing for the second item; and

simultaneously uploading the first listing and the second listing to the network-based publication system.

19. The system of claim 11 , wherein the operations further comprise:

causing display of a message on the user interface, the message including a question inviting a user response to confirm if the image represents the item.

20. A non-transitory machine-readable storage medium having stored instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

receiving image data from a mobile device;

identifying, based on the image data, an item and a product characteristic of the item;

generating listing data of the item based on the product characteristic;

determining that the item is associated with a product category;

identifying a set of listings associated with the product category;

applying a decay formula to the set of listings to generate a discounted number of sales and a discounted number of impressions for at least one listing of the set of listings;

determining a ratio of the discounted number of sales to the discounted number of impressions;

determining a ranking of the set of listings based on the ratio;

generating a price estimate of the item based on the ranking of the set of listings and the ratio of the discounted number of sales to the discounted number of impressions; and

causing display, by a computing device, of a user interface that includes a user selectable user interface (UI) element associated with a request to list the item, the request including the listing data and the price estimate of the item.
