I. INTRODUCTION 
The work described in the present paper represents a 
combination of two widely different approaches to the 
study of language. The first of these, the automatic gen- 
eration of sentences by computer, is recent and highly 
specialized: Yngve (1962), Sakai and Nagao (1965), 
Arsent'eva (1965), Lomkovskaja (1965), Friedman (1967), 
and Harper (1967) have applied a sentence generator to the 
study of syntactic and semantic problems of the level of 
the (isolated) sentence. The second, the study of units 
of discourse larger than the sentence, is as old as rhetor- 
ic, and extremely broad in scope; it includes, in one way 
or another, such diverse fields as beyond--the sentence 
analysis (cf. Hendricks, 1967) and the linguistic study of 
literary texts (Bailey, 1968, 53--76). The present study 
is an application of the technique of sentence generation 
to an analysis of the paragraph; the latter is seen as a 
unit of discourse composed of lower-level units (sentences), 
and characterized by some kind of structure. To repeat: 
the object of our investigation is the paragraph; the 
technique is analysis by synthesis, i.e. via the automatic 
generation of strings of sentences that possess the 
properties of paragraphs.
