Generation of data filters from natural language queries

A computer-implemented method comprising:

• receiving, via a user interface component of at least one server of one or more servers of a query processing system, a natural language query from a user device;
• generating, by a generative model, an initial filter based on the natural language query, the initial filter comprising an initial attribute value and an initial attribute name with an operator associating the initial attribute name and the initial attribute value, wherein the initial filter is noisy because the initial attribute name does not exactly match any valid attribute name in a structured dataset and/or the initial attribute value does not exactly match any valid attribute value in the structured dataset;
• determining, by an attribute resolving component of at least one server of the one or more servers, that the initial filter corresponds to a non-numeric attribute;
• identifying, by the attribute resolving component, a valid attribute value corresponding to the initial attribute value by:
• searching an exact match data store storing data for a plurality of valid attribute values in the structured dataset,
• when an exact match for the initial attribute value is found from the exact match data store, identifying the initial attribute value as the valid attribute value, and
• when an exact match for the initial attribute value is not found from the exact match data store, performing a similarity-based matching operation to identify the valid attribute value based on similarity to the initial attribute value;
• identifying, by the attribute resolving component, a valid attribute name corresponding to the initial attribute name;
• generating, by a valid filter component of at least one server of the one or more servers, a valid filter from the initial filter by replacing the initial attribute value in the initial filter with the valid attribute value and/or replacing the initial attribute name in the initial filter with the valid attribute name;
• querying, by a data retrieval component of at least one server of the one or more servers, a data store storing the structured dataset using the valid filter to access data;
• and
• providing, by the user interface component, a response to the natural language query that contains the accessed data.

A computer system comprising:

• one or more processors;
• and
• one or more computer storage media storing computer-useable instructions that, when used by the one or more processors, causes the computer system to perform operations comprising:
• receiving, by a user interface component of at least one server of one or more servers of a query processing system, a natural language query;
• generating, by a generative model, an initial filter based on the natural language query, the initial filter comprising an initial attribute value and an initial attribute name with an operator associating the initial attribute name and the initial attribute value, wherein the initial filter is noisy because the initial attribute name does not exactly match any valid attribute name in a structured dataset and/or the initial attribute value does not exactly match any valid attribute value in the structured dataset;
• identifying, by an attribute resolving component of at least one server of the one or more servers, a valid attribute value corresponding to the initial attribute value and a valid attribute name corresponding to the initial attribute name;
• generating, by a valid filter component of at least one server of the one or more servers, a valid filter by replacing the initial attribute value in the initial filter with the valid attribute value and replacing the initial attribute name in the initial filter with the valid attribute name;
• retrieving, from the structured dataset, data using the valid filter;
• and
• providing, by the user interface component, a response to the natural language query using the retrieved data.
