This paper describes an analysis of telegraphic fragments as regular structures (not errors) handled by rn~n~nal extensions to a system designed for processing the standard language. The modular approach which has been implemented in the Unlsys natural language processing system PUNDIT is based on a division of labor in which syntax regulates the occurrence and distribution of elided elements, and semantics and pragumtics use the system's standard mechankms to interpret them. | SENTENCE FRAGMENTS REGULAR STRUCTURES Marcia c.

Box 517 Paoli PA ABSTRACT This paper describes an analysis of telegraphic fragments as regular structures not errors han-died by minimal extensions to a system designed for processing the standard language. The modular approach which has been implemented in the Unisys natural language processing system PUNDIT is based on a division of labor in which syntax regulates the occurrence and distribution of elided elements and semantics and pragmatics use the system s standard mechanisms to interpret them. 1. INTRODUCTION In this paper we discuss the syntactic semantic and pragmatic analysis of fragmentary sentences in English. Our central claim is that these sentences which have often been classified in the literature with truly erroneous input such as misspellings see for example the work discussed in Kwasnyl980 Thompsonl980 Kwasnyl981 Sondheimerl983 Eastmanl981 Jen-senl983 are regular structures which can be processed by adding a small number of rules to the grammar and other components of the system. The syntactic regularity of fragment structures has been demonstrated elsewhere notably in ỊMarshl983 Hirschmanl983 we will focus here upon the regularity of these structures across all levels of linguistic representation. Because the syntactic component regularises these structures into a form almost indistinguishable from full This work hat been tupported in part by DARPA under contract N00014-8 -C-0012 adminiitered by the Office of Naval Research by National Science Foundation contract DCR-8S-0220S and by Independent R D funding from System Development Corporation now part of Unisys Corporation.
