Open Text Summarizer is an open source tool for
summarizing text. It reads a text stream and
decides which sentences are important. It is both a
library and a command line tool. External
applications, such as word processors, can link to
the library, while the command line tool summarizes
text on the console. It can output as either plain
text or HTML. When output as HTML, the important
sentences are highlighted. It is multi-lingual and
supports UTF-8 encoding.
