14. A system for providing assistance with reporting, comprising: one or more computer processors configured to: associate a structure data element of a structured document with an associated part of a report, the report including text in a natural language, and the structured data element represents information corresponding to information represented by the associated part of the report, determine a change to one of the structured data element and the associated part of the report, to obtain a determined change including: inserting a representation of information into the one of the structured data element of the structured document and the associated part of the report; and make a corresponding change to the other one of the structured data element and the associated part of the report, based on the determined change including: inserting a corresponding representation of information into the other one of the structured data element and the associated part of the report, and converting the inserted representation of information, being a new structured data element, by applying natural language generation to generate a piece of natural language suitable for insertion into the associated part of the report.
