The output of the parser, known as "syntactic f-structure", is then fed into a mapper to produce an Interlingua representation. For the mapper, we use a software tool known as Transformation Kit [10]. A mapping grammar with about 300 rules is written for the Conference Registration domain of English.
Figure 2 is an example of Interlingua representation produced from the sentence "Hello is this the conference office". In the example, "Hello" is represented as speech-act *ACKNOWLEDGEMENT, and the rest as speech-act *IDENTFY-OTHER.
