Verification of information object attributes

A system, comprising:

• a memory;
• a processor, coupled to the memory, the processor configured to:
• receive a first attribute value and a second attribute value associated with an information object representing an entity referenced by a natural language text;
• evaluate a confidence function to determine a first confidence level associated with the first attribute value and a second confidence level associated with the second attribute value, wherein the confidence function is associated with a set of production rules, wherein the first attribute value and the second attribute value are produced by the set of production rules;
• responsive to determining that the first confidence level falls below a threshold confidence value, display the first attribute value using a verification graphical user interface;
• responsive to receiving, via the verification graphical user interface, a first input confirming the first attribute value, perform at least one of:
• increasing the first confidence level by a first pre-defined value or setting the first confidence level to a second pre-defined value;
• display the second attribute value using the verification graphical user interface;
• and
• responsive to failing to receive, before a triggering event, via the verification graphical user interface, a second input verifying the second attribute value, perform at least one of:
• increasing the second confidence level by a third pre-defined value or setting the second confidence level to a fourth pre-defined value, wherein the third pre-defined value is less than the first pre-defined value and the fourth pre-defined value is less than the second pre-defined value.

A computer-readable non-transitory storage medium comprising executable instructions that, when executed by a computer system, cause the computer system to:

• receive a first attribute value and a second attribute value associated with an information object representing an entity referenced by a natural language text;
• evaluate a confidence function to determine a first confidence level associated with the first attribute value and a second confidence level associated with the second attribute value, wherein the confidence function is associated with a set of production rules, wherein the first attribute value and the second attribute value are produced by the set of production rules;
• responsive to determining that the first confidence level falls below a threshold confidence value, display the first attribute value using a verification graphical user interface;
• responsive to receiving, via the verification graphical user interface, a first input confirming the first attribute value, perform at least one of:
• increasing the first confidence level by a first pre-defined value or setting the first confidence level to a second pre-defined value;
• display the second attribute value using the verification graphical user interface;
• and
• responsive to failing to receive, before a triggering event, via the verification graphical user interface, a second input verifying the second attribute value, perform at least one of:
• increasing the second confidence level by a third pre-defined value or setting the second confidence level to a fourth pre-defined value, wherein the third pre-defined value is less than the first pre-defined value and the fourth pre-defined value is less than the second pre-defined value.
