What you see is what you meant (WYSIWYM) is a text editing interaction technique that emerged from two projects at University of Brighton.
It allows users to create abstract knowledge representations such as those required by the Semantic Web using a natural language interface.
Instead, natural language generation (NLG) is used in a highly interactive manner.
An invisible representation of the semantic knowledge is created which can be used for multilingual document generation, formal knowledge formation, or any other task that requires formally specified information.
[1] The two projects at Brighton worked in the field of Conceptual Authoring to lay a foundation for further research and development of a Semantic Web Authoring Tool (SWAT).
