Trained sequence-to-sequence conversion of database queries

A system comprising:

• one or more processors;
• and
• memory communicatively coupled to the one or more processors, the memory storing computer-executable modules executable by the one or more processors that, when executed by the one or more processors, perform associated operations, the computer-executable modules comprising:
• an encoding module further comprising:
• a co-attention submodule configured to compute co-attention for a search query and a context string;
• a first self-attention submodule configured to compute self-attention for the search query;
• and
• a second self-attention submodule configured to compute self-attention for the context string based on trained structural attention heads;
• and
• a decoder module configured to compute the self-attention-computed search query and the self-attention-computed context string by a multi-pointer-generator and output a structured database query.

A computer-readable storage medium storing computer-readable instructions executable by one or more processors, that when executed by the one or more processors, cause the one or more processors to perform operations comprising:

• computing co-attention for a search query and a context string;
• computing self-attention for the search query;
• computing self-attention for the context string based on trained structural attention heads;
• computing the self-attention-computed search query and the self-attention-computed context string by a multi-pointer-generator;
• and
• outputting a structured database query.
