Rule-based item classification

One or more computer-readable media storing computer-executable instructions that, when executed on one or more processors, cause the one or more processors to perform acts comprising:

• receiving an item record associated with an item, the item record comprising a description of the item;
• classifying the item based on the item record using a plurality of rule-based classifiers to generate a first ranked list of item types;
• classifying the item based on the item record using a plurality of attribute-based classifiers to generate a second ranked list of item types;
• and
• combining the first ranked list of item types and the second ranked list of item types to generate a combined ranked list of item types.

An apparatus comprising:

• a memory configured to store data and one or more sets of instructions;
• and
• one or more processors coupled to the memory, the one or more processors configured to execute the one or more sets of instructions and perform operations comprising:
• receiving an item record associated with an item, the item record comprising a description of the item;
• generating a first ranked list of item types based on the item record using a plurality of rule-based classifiers;
• generating a second ranked list of item types based on the item record using a plurality of machine learning-based classifiers;
• and
• aggregating the first ranked list of item types and the second ranked list of item types to generate a combined ranked list of item types.
