This technical report contains a dissertation submitted for the degree of Doctor of Philosophy in the University of Cambridge. This dissertation discusses the investigation of the hypothesis that the generation of multiple utterances, as with planning single utterances Appelt, 1985, is a plan-based activity that is based on communicative acts. This requires the analysis of text in search for underlying communicative acts that achieve distinct effects of the hearers knowledge, beliefs, and desires. Thus this dissertation investigates the communicative structure and communicative function of a range of explanations for knowledge based systems. Related to this is the issue of how focus constrains generation Sidner, 1979 McKeown, 1982 and so a second theoretical aim is to investigate how attentional constraints relate to text planning and linguistic realization.
