Parsing with GETARUN

GETARUNS, the system for text and reference understanding which is currently used for summarization and text generation has a highly linguistically sophisticated parser which implements a number of strategies to cope with ambiguity ensuing from PP attachment and other similar problems(see Delmonte & Dolci, 1997). In this paper we present the parser from a linguistic point of view and as such implementing LFG theoretical framework within a DCG, using Xtraposition Grammars to cope with Long Distance Dependencies. The parser is multilingual and contains a lookahead mechanism, which is then used by the Well-Formed-Substring-Table to recover wrongly parser attachment.
