An improved system and method for providing context information of executable code to an input method is provided. Advanced text input methods may be made aware of the type of text expected to be received as input so that input methods may achieve a higher accuracy in recognition of text input. Generic interfaces provide a framework for supporting application authoring platforms to allow application developers to easily specify context information to the system and have it reliably forwarded to the correct input methods. Additionally, a context tagging tool may associate specific text input fields of an existing application with an input scope without modifying the application itself. The context tagging tool may create a manifest that contains tags associating the specific text input fields with an input scope. Any advanced input methods use by the application may be updated with instructions for accessing the context information stored in the manifest.
