Assignee: WALMART APOLLO, LLC
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A system comprising:
a database; and
a computing device communicatively coupled to the database and configured to:
receive input data comprising a plurality of characters;
apply a Bidirectional Encoder Representation from Transformers (BERT) model to the input data to generate first output embeddings, wherein the computing device is configured to train the BERT model based on catalog data identifying one or more attributes of a plurality of items and chat session data;
apply a dependency embedding generation model to the input data to generate second output embeddings, wherein the dependency embedding generation model comprises a syntactic dependency embedding model configured to generate syntactic dependencies based on the input data, a transformer encoder comprising a single layer transformer block configured to generate encoded data from the syntactic dependencies, and a linear network configured to generate the second output embeddings based on the encoded data, and wherein the dependency embedding generation model is applied in parallel with the BERT model;
generate concatenated embeddings by stepwise concatenation of the first output embeddings and the second output embeddings;
determine, based on applying a classifier model to the concatenated embeddings, output values; and
store the output values in the database.
