Shelf-specific facet extraction

A method implemented via execution of computing instructions configured to run at a processor, the method comprising:

• obtaining a keyword query through a graphical user interface;
• obtaining search results corresponding to the keyword query;
• obtaining, by the processor, one or more predicted shelves corresponding to the keyword query;
• determining linked categorical facets corresponding to the one or more predicted shelves based on shelf-categorical facet linkages in a shelf-categorical facet linkage table, wherein the shelf-categorical facet linkages in the shelf-categorical facet linkage table comprise linkages between browse shelves and categorical facet values, wherein the browse shelves in the shelf-categorical facet linkages in the shelf-categorical facet linkage table each comprise a respective shelf name within a product taxonomy of an electronic item catalog, wherein the linked categorical facets comprise the categorical facet values linked to the one or more predicted shelves in the shelf-categorical facet linkages in the shelf-categorical facet linkage table, wherein the categorical facet values contain categorical information that applies across multiple browse shelves, and wherein the one or more predicted shelves are one or more of the browse shelves;
• performing fuzzy matching of keywords of the keyword query with (i) shelf-specific facet representation mappings that are generated and stored before the keyword query is obtained and (ii) the linked categorical facets, based on a tolerance threshold for character-level mismatches, to determine candidate shelf-specific facets, wherein the tolerance threshold for the character-level mismatches increases dynamically according to a text length of the keyword query, wherein the shelf-specific facet representation mappings comprise shelf-specific facet types and shelf-specific augmented facet values, and wherein the shelf-specific augmented facet values are generated based on inflected forms, derived forms, and synonyms of facet values;
• determining, by the processor, one or more shelf-specific facets from the candidate shelf-specific facets based on facet information in the candidate shelf-specific facets, wherein the one or more shelf-specific facets correspond to one or more shelves of the one or more predicted shelves;
• and
• outputting, on the graphical user interface in real-time after receiving the keyword query, adjacent to the search results displayed responsive to the keyword query, (i) the one or more shelves of the one or more predicted shelves that correspond to the one or more shelf-specific facets from the candidate shelf-specific facets and (ii) one or more respective shelf-specific facets of the one or more shelf-specific facets that correspond to each of the one or more shelves, wherein the graphical user interface comprises selectable options for the one or more shelf-specific facets that correspond to the one or more shelves to enable filtering the search results on the graphical user interface based on the one or more shelf-specific facets that correspond to the one or more shelves.

A non-transitory computer-readable medium storing computing instructions that, when executed on a processor, cause the processor to perform operations comprising:

• obtaining a keyword query through a graphical user interface;
• obtaining search results corresponding to the keyword query;
• obtaining one or more predicted shelves corresponding to the keyword query;
• determining linked categorical facets corresponding to the one or more predicted shelves based on shelf-categorical facet linkages in a shelf-categorical facet linkage table, wherein the shelf-categorical facet linkages in the shelf-categorical facet linkage table comprise linkages between browse shelves and categorical facet values, wherein the browse shelves in the shelf-categorical facet linkages in the shelf-categorical facet linkage table each comprise a respective shelf name within a product taxonomy of an electronic item catalog, wherein the linked categorical facets comprise the categorical facet values linked to the one or more predicted shelves in the shelf-categorical facet linkages in the shelf-categorical facet linkage table, wherein the categorical facet values contain categorical information that applies across multiple browse shelves, and wherein the one or more predicted shelves are one or more of the browse shelves;
• performing fuzzy matching of keywords of the keyword query with (i) shelf-specific facet representation mappings that are generated and stored before the keyword query is obtained and (ii) the linked categorical facets, based on a tolerance threshold for character-level mismatches, to determine candidate shelf-specific facets, wherein the tolerance threshold for the character-level mismatches increases dynamically according to a text length of the keyword query, wherein the shelf-specific facet representation mappings comprise shelf-specific facet types and shelf-specific augmented facet values, and wherein the shelf-specific augmented facet values are generated based on inflected forms, derived forms, and synonyms of facet values;
• determining one or more shelf-specific facets from the candidate shelf-specific facets based on facet information in the candidate shelf-specific facets, wherein the one or more shelf-specific facets correspond to one or more shelves of the one or more predicted shelves;
• and
• outputting, on the graphical user interface in real-time after receiving the keyword query, adjacent to the search results displayed responsive to the keyword query, (i) the one or more shelves of the one or more predicted shelves that correspond to the one or more shelf-specific facets from the candidate shelf-specific facets and (ii) one or more respective shelf-specific facets of the one or more shelf-specific facets that correspond to each of the one or more shelves, wherein the graphical user interface comprises selectable options for the one or more shelf-specific facets that correspond to the one or more shelves to enable filtering the search results on the graphical user interface based on the one or more shelf-specific facets that correspond to the one or more shelves.
