( 'What you see is what you meant') is a user-interface technique which uses natural language generation (NLG) technology to provide feedback for user interactions. To date, the technology has been applied in a number of demonstrator applications, using customised, nonportable implementations. In this demonstration, we introduce a WYSIWYM library package, designed to be used as a modular component of a larger JAVA-based application. We show how the overall design of the package aims to support a range of possible applications using simple configuration options and JAVA subclassing, and illustrate the approach using examples ranging from the simplest proof-of-concept. | WYSIWYM - building user interfaces with natural language feedback Roger Evans and Richard Power Information Technology Research Institute University of Brighton 1 Introduction WYSIWYM What you see is what you meant is a user-interface technique which uses natural language generation NLG technology to provide feedback for user interactions.

In this demonstration we introduce a WYSIWYM library package designed to be used as a modular component of a larger JAVA-based application. We show how the overall design of the package aims to support a range of possible applications using simple configuration options and JAVA subclassing and illustrate the approach using examples ranging from the simplest proof-of-concept application to a complex web-delivered authoring tool for pharmaceutical leaflets. 2 WYSIWYM - a brief history The WYSIWYM architecture A long-standing research goal has been to enable subject matter experts SMEs to create or modify a knowledge base directly without need for specialised training in knowledge representation languages this is the main objective for example of the Rapid Knowledge Formation project Clark et al. 2001 . Several research groups have developed direct-manipulation interfaces in which the current state of the knowledge base and the options for editing it are displayed diagrammatically Skuce and Lethbridge 1995 Paley 1996 Grosso et al. 2000 . The basic idea of WYSIWYM is to pro vide a direct-manipulation interface in which the knowledge is displayed through a feedback text generated automatically from the current knowledge base. Options for editing are shown through pop-up menus which open on spans of the feedback text. Unfilled slots in the knowledge base are shown through coloured text spans called anchors the wording of the anchor indicating
