Natural Language Question Answering Systems

A method comprising:

• receiving string data entered via a user interface;
• determining a sequence of tokens representative of the string data, wherein determining the sequence of tokens includes applying natural language processing to the string data;
• generating a first database query in accordance with the sequence of tokens;
• presenting, via the user interface, respective text representations for tokens in the sequence of tokens;
• receiving feedback data related to the sequence of tokens via the user interface;
• modifying a token of the sequence of tokens based on the feedback data to obtain a modified sequence of tokens;
• generating a second database query based on the modified sequence of tokens;
• obtaining results data from the database responsive to execution of the second database query by the database;
• and
• outputting data based on the results data for presentation in the user interface.

A system for providing a search interface for a database, comprising:

• a memory;
• and
• a processor, the processor configured to execute instructions stored in the memory to:
• receive string data entered via a user interface;
• determine a sequence of tokens representative of the string data, wherein to determine the sequence of tokens includes to apply natural language processing to the string data;
• generate a first database query in accordance with the sequence of tokens;
• present, via the user interface, respective text representations for tokens in the sequence of tokens;
• receive feedback data related to the sequence of tokens via the user interface;
• modify a token of the sequence of tokens based on the feedback data to obtain a modified sequence of tokens;
• generate a second database query based on the modified sequence of tokens;
• obtain results data from the database responsive to an execution of the second database query by the database;
• and
• output data based on the results data for presentation in the user interface.

A non-transitory computer-readable storage medium that includes instructions that, when executed by a processor, facilitate performance of operations comprising:

• receiving string data entered via a user interface;
• determining a sequence of tokens representative of the string data, wherein determining the sequence of tokens includes applying natural language processing to the string data;
• generating a first database query in accordance with the sequence of tokens;
• presenting, via the user interface, respective text representations for tokens in the sequence of tokens;
• receiving feedback data related to the sequence of tokens via the user interface;
• modifying a token of the sequence of tokens based on the feedback data to obtain a modified sequence of tokens;
• generating a second database query based on the modified sequence of tokens;
• obtaining results data from the database responsive to execution of the second database query by the database;
• and
• outputting data based on the results data for presentation in the user interface.
