Abstract
In a processor for extracting information on a specified field from a text described in a natural language, keywords and structural analysis are jointly used to improve the performance. When a set of keywords is divided in more than one sentence, this set of keywords is assembled by context defining words in a sentence. A multi-language summary generator uses this type of a processor.
