Framework for data extraction by examples

A computing system, comprising:

• at least one processor;
• and
• memory that comprises computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform acts including:
• executing inductive synthesis algorithms for core operators in a predefined library;
• and
• synthesizing an extraction program for extracting data from an input document by executing the inductive synthesis algorithms, the extraction program being synthesized in a domain specific language (DSL) for an input document type of the input document, the DSL being constructed from the predefined library of the core operators.

A method of controlling interactions for data extraction programming, comprising:

• receiving user input that defines an output data schema, the output data schema comprises a hierarchical combination of structure and sequence constructs;
• receiving examples of data to extract from an input document, the examples comprise at least one example for each of the constructs of the output data schema;
• responsive to receiving the examples, causing at least one processor to incorporate graphical representations of the examples over the input document as part of a uniform user interface, the uniform user interface being for a plurality of different input document types;
• and
• causing the at least one processor to incorporate a graphical representation of an instance of the output data schema extracted from the input document based on the examples, the graphical representation of the instance of the output data schema being incorporated over the input document as part of the uniform user interface.
