A system is described for acquiring a contextsensitive, phrase structure g r a m m a r which is applied by a best-path, bottom-up, deterministic parser. The grammar was based on English news stories and a high degree of success in parsing is reported. Overall, this research concludes that CSG is a computationally and conceptually tractable approach to the construction of phrase structure g r a m m a r for news story text. 1 A context-free g r a m m a r production is characterized as a rewrite rule where a non-terminal element as a leftside.
