Jet (Java Extraction Toolkit) 
    
    About JET
    JET, the Java Extraction Tool, provides a variety of components
      for language analysis, such as sentence segmentation, name
      tagging, time expression tagging and normalization, part-of-speech
      tagging, partial parsing, and coreference analysis.  These
      components can be arranged in pipelines for different
      applications, and can be used either for interactive analysis of
      individual sentences, or 'batch' analysis of complete documents.
      Simple tools are provided for annotating documents and displaying
      annotated documents.  A full set of procedures are also
      provided for performing information extraction of entities,
      relations, and events following the ACE [Automatic Content
      Extraction] specifications.
    JET is a work in progress, and continues being regularly expanded
      and updated.

    it into software you distribute, we earnestly request that you
    notify Prof. Ralph Grishman.
    Installing Jet
    You need Java 1.5 or later in order to run Jet.  It runs under
    linux and Apple Mac OS X through terminal windows.
    
    Download the latest Jet distribution tar file and extract all the
    files with tar -xzvf.
    
    The expanded directory will include
    
      - jet-all.jar, the
        Jet 'executable' (including all libraries)
- bin, a directory with simple scripts for invoking Jet
 
- docs, a directory
        of user documentation files
- props, a
        directory of configuration files
- data, a directory
        of data files used by Jet
In addition, the directory will contain the following files and
      directories for those who wish to recompile or modify Jet
    
    
      - src, a directory with the Jet source files
- test, a directory with source files of Jet unit tests
- parser-stub-src, stub sources for a statistical
        parser
- lib, a directory containing other jar files required
        by Jet
- build.xml, scripts for building Jet using ant
To use Jet,
    
      - add the bin directory to your path
- set the environment variable JET_HOME to point to
        the top directory into which the Jet files have been unpacked
