One embodiment provides a method including: receiving input indicating at least one concept from at least one document of an input document collection; generating a validated data model for each of a plurality of concepts, wherein each of the concepts is represented as a visual data structure comprising semantics; generating at least one intermediate model object by parsing the validated data model, wherein each of the intermediate model objects comprises a concept object and the at least one intermediate model object identifies concept dependencies; translating the at least one intermediate model object into executable source code by importing at least one pre-built extractor and translating at least one rule identified from the visual data structure; and generating an executable information extraction program from the executable source code, wherein the generating comprises generating at least one rule for the executable information extraction program based on the identified concept dependencies.

Translation of a visual representation into an executable information extraction program

One embodiment provides a method for generating an executable extraction program from a visual representation, the method including: utilizing at least one processor to execute computer code that performs the steps of: obtaining a validated model comprising a plurality of concepts, wherein each of the concepts comprises semantics associated with a visual representation of an object; generating at least one intermediate model object by parsing the validated model, wherein each of the intermediate model objects comprises a concept object; translating the at least one intermediate model object into executable source code; and generating an executable information extraction program from the executable source code. Other aspects are described and claimed.

Techniques are disclosed for providing support for objects that are selectably mutable during runtime. In one embodiment, an application programming interface (API) is provided that includes procedures for sealing and unsealing an object during runtime. Applications may use the API to prevent the object from being inadvertently modified, without having to create defensive copies of the object. Accordingly, processing and/or memory costs associated with executing the application may be reduced.
