Systems for generating a global product taxonomy

摘要

Techniques for generating a globally applicable taxonomy of e-commerce goods are described. According to various exemplary embodiments described herein, a taxonomy management system is configured to analyze item listing titles and user search queries in order to identify a set of globally applicable product types that serve as universal descriptors of the underlying things or objects that are the subject of an item listing or the likely user intended subject of a user search query. Such globally applicable product types are agnostic as to any specific product inventory or product category structure of an e-commerce website. After the taxonomy management system identifies product types, the taxonomy management system may incorporate the identified product types into a global product taxonomy that identifies the globally applicable product types.

1. A method comprising:
accessing at least one of an item listing title associated with an item listing of an e-commerce website and a user search query associated with an item search request submitted to the e-commerce website; converting words in the listing title or user search query to semantic tokens in a token symbol space, based on a tokenizing process; determining, using one or more processors, that one or more of the tokens are attribute values associated with predefined attributes of one or more product categories in a product category structure of the e-commerce website; classifying, using the one or more processors, remaining ones of the tokens as candidate product type tokens associated with a global product taxonomy; identifying frequent terms in leaf categories associated with the product category structure of the e-commerce website; determining an entropy value of each of the candidate product type tokens based on the frequent terms in the leaf categories; and ranking each of the candidate product type tokens, based on the entropy value associated with each of the candidate product type tokens.
