METHOD FOR RECOMMENDING PRODUCTS BASED ON A USER PROFILE DERIVED FROM METADATA OF MULTIMEDIA CONTENT
Techniques disclosed herein describe identifying one or more products to recommend to a plurality of users based on metadata of digital multimedia files. A product feed extractor extracts a product feed. The product feed lists one or more items. The product feed extractor identifies, for each item in the product feed, one or more attributes describing the item. Each item is mapped to concepts of an interest taxonomy based on the identified one or more attributes for the item. One or more users are associated with each concept in the interest taxonomy based on the metadata of the digital multimedia files. Each item is associated to one or more of the users based on the mapping.
1 . A method for identifying one or more products to recommend to a plurality of users based on metadata of digital multimedia files, the method comprising:
extracting a product feed, wherein the product feed lists one or more items;
identifying, for each item in the product feed, one or more attributes describing the item;
mapping each item to concepts of an interest taxonomy based on the identified one or more attributes for the item, wherein one or more users are associated with each concept in the interest taxonomy based on the metadata of the digital multimedia files; and
associating each item to one or more of the users based on the mapping.
2 . The method of claim 1 , wherein the identified attributes include at least one of a name of the item, a price of the item, a description of the item, and a type of the item.
3 . The method of claim 1 , further comprising:
for each attribute identified for the item, updating an item-attribute matrix to reflect the attribute identified for the item.
4 . The method of claim 3 , wherein mapping each item to the concepts of the interest taxonomy comprises:
evaluating the item-attribute matrix to determine at least a first concept to associate with the item.
5 . The method of claim 4 , further comprising:
updating an item-concept matrix to reflect the attribute identified for the first concept.
6 . The method of claim 4 , wherein the first concept is determined based on a co-occurrence between one or more attributes in the item-attribute matrix.
7 . The method of claim 1 , wherein each of the digital multimedia files is one of either an image or a video.
8 . A non-transitory computer-readable storage medium storing instructions, which, when executed on a processor, performs an operation for identifying one or more products to recommend to a plurality of users based on metadata of digital multimedia files, the operation comprising:
extracting a product feed, wherein the product feed lists one or more items;
identifying, for each item in the product feed, one or more attributes describing the item;
mapping each item to concepts of an interest taxonomy based on the identified one or more attributes for the item, wherein one or more users are associated with each concept in the interest taxonomy based on the metadata of the digital multimedia files; and
associating each item to one or more of the users based on the mapping.
9 . The non-transitory computer-readable storage medium of claim 8 , wherein the identified attributes include at least one of a name of the item, a price of the item, a description of the item, and a type of the item.
10 . The non-transitory computer-readable storage medium of claim 8 , wherein the operation further comprises:
for each attribute identified for the item, updating an item-attribute matrix to reflect the attribute identified for the item.
11 . The non-transitory computer-readable storage medium of claim 10 , wherein mapping each item to the concepts of the interest taxonomy comprises:
evaluating the item-attribute matrix to determine at least a first concept to associate with the item.
12 . The non-transitory computer-readable storage medium of claim 11 , wherein the operation further comprises:
updating an item-concept matrix to reflect the attribute identified for the first concept.
13 . The non-transitory computer-readable storage medium of claim 11 , wherein the first concept is determined based on a co-occurrence between one or more attributes in the item-attribute matrix.
14 . The non-transitory computer-readable storage medium of claim 8 , wherein each of the digital multimedia files is one of either an image or a video.
15 . A system, comprising:
a processor; and
a memory storing one or more application programs configured to perform an operation for identifying one or more products to recommend to a plurality of users based on metadata of digital multimedia files, the operation comprising:
extracting a product feed, wherein the product feed lists one or more items,
identifying, for each item in the product feed, one or more attributes describing the item,
mapping each item to concepts of an interest taxonomy based on the identified one or more attributes for the item, wherein one or more users are associated with each concept in the interest taxonomy based on the metadata of the digital multimedia files, and
associating each item to one or more of the users based on the mapping.
16 . The system of claim 15 , wherein the identified attributes include at least one of a name of the item, a price of the item, a description of the item, and a type of the item.
17 . The system of claim 15 , wherein the operation further comprises:
for each attribute identified for the item, updating an item-attribute matrix to reflect the attribute identified for the item.
18 . The system of claim 17 , wherein mapping each item to the concepts of the interest taxonomy comprises:
evaluating the item-attribute matrix to determine at least a first concept to associate with the item.
19 . The system of claim 18 , wherein the operation further comprises:
updating an item-concept matrix to reflect the attribute identified for the first concept.
20 . The system of claim 18 , wherein the first concept is determined based on a co-occurrence between one or more attributes in the item-attribute matrix.
21 . The system of claim 15 , wherein each of the digital multimedia files is one of either an image or a video.
