Mapping item records to product records

A system comprising:

• an item database;
• a hardware-implemented analysis module communicatively coupled to the item database, the analysis module being configured to:
• access a seller-generated item description received from a seller of an item, the item description being descriptive of the item;
• infer an attribute and an attribute value based on the item description;
• and
• include the attribute and the attribute value in an item record for the item, the item record being stored in an item database;
• and
• a hardware-implemented mapping module communicatively coupled to the item database, the mapping module being configured to:
• present a product record stored in a product database to the seller as a proposed record to be mapped to the item record;
• receive an acceptance of the proposed record from the seller;
• increment an acceptance count corresponding to the product record;
• and
• map the item record to the product record by including a reference to the product record in the item record based on the attribute and on the attribute value.

A computer-implemented method comprising:

• accessing an item database storing item records, each of the item records including an attribute, an attribute value, and a reference to a product record of a plurality of product records;
• accessing a product database storing the plurality of product records, the product database being representative of a decision tree having end nodes, each of the end nodes corresponding uniquely to one of the plurality of product records;
• performing an analysis of the product database based on the item records and on the plurality of product records, the analysis including a determination of a compression ratio based on a first total number of item records and on a second total number of product records, the analysis being performed by a hardware-implemented manager module of a machine;
• modifying the product database based on the analysis, the modifying being performed by the hardware-implemented manager module of the machine.

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

• accessing a seller-generated item description received from a seller of an item, the item description being descriptive of the item;
• inferring an attribute and an attribute value based on the item description;
• including the attribute and the attribute value in an item record for the item, the item record being stored in an item database;
• presenting a product record stored in a product database to the seller as a proposed record to be mapped to the item record;
• receiving an acceptance of the proposed record from the seller;
• incrementing an acceptance count corresponding to the product record;
• and
• mapping the item record to the product record by including a reference to the product record in the item record, the mapping being based on the attribute and on the attribute value.
