Question Answering in the Swedish Core Language Engine

The paper describes how the Swedish Core Language Engine (S-CLE), a general-purpose natural-language processing system was extended to process questions posed to a Prolog database. Previous work on the S-CLE has included processing up to the level of quasi-logical form (QLF); here we address the problems encountered when extending that processing to "pure" logical form (LF) and translating the logical forms into questions to the SNACK85 reginal database. We also show how some natural-language answers were generated from the original question-QLFs and the answers obtained from the database
