LAPIS is a free, open source program written in Java. We have tested the latest release on Windows XP and Linux with Java 1.4.

The latest release of LAPIS is version 1.2, released on October 19, 2003. See the change history to find out what's new.

This is alpha software. Its use and redistribution are subject to the conditions shown below. Please send bug reports, comments, and suggestions to the LAPIS group (lapis@graphics.lcs.mit.edu).

These instructions assume that you have Java 1.4 or later installed on your computer. If you're not sure, try running java -version. If you need to install Java on Windows, Linux, or Solaris, go directly to Sun; for other platforms, consult the list of Java ports.

Optional: If you want to use the English.PartOfSpeech parser (which identifies nouns, verbs, adjectives, etc.), you need to have Perl installed and accessible on your search path. Most Unix platforms include Perl. For Windows, you can get Perl from ActiveState or Cygwin. The English.PartOfSpeech parser itself is written in C. The LAPIS distribution includes precompiled binaries only for Linux and Windows; other platforms must recompile the parser in lapis-1.2/parsers/external/RULE_BASED_TAGGER_V1.14.

1. Download the ZIP file:

lapis-1.2.zip (5 MB)

2. Extract all the files from the ZIP file to your hard disk.
3. Change directory into lapis-1.2.
4. Change directory into bin.
5. Run LAPIS. The exact program to run depends on what platform you're using:

Windows	Unix/MacOS X
`lapis.exe`	`lapis`

LAPIS may take a moment to load. If nothing happens, or you get an error message like "can't find class", then you may need to install a newer version of Java. LAPIS is open source. The source code is included with the download, in lapis-1.2/src.zip.
