Question Answering in the Swedish Core Language Engine

Abstract

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 SNACK-85 reginal database. We also show how some natural-language answers were generated from the original question-QLFs and the answers obtained from the database.
