Essence can summarise documents in several languages and is surprisingly accurate.
The package is also very easy to use and offers many choices for fine-tuning summaries. Erik Vlietinck reports Essence is an abstract-generation tool, capable of automatically generating summaries of documents in several languages. It runs under Windows 95, NT 3.51 and NT 4.0. The software can summarise text or HTML files, and is aimed at knowledge workers, journalists and other people who have to swiftly access, read and understand medium-sized to large documents. The interface of the stand-alone version is simple to learn.
