Re: mallet addon

[Rodrigo Agerri]

Hello,

Thanks. I thought I had an idea for CRF not obtaining good results
with OpenNLP default features, e.g.,

http://lingpipe-blog.com/2006/11/22/why-do-you-hate-crfs/

but if results are also worse in Maxent, that is intriguing. I will
look at the Mallet implementation to see if I find out something.

Re: mallet addon

Hello,

I updated the code and afterwards spent some time evaluating it again. The
maxent training is very close to our maxent classifier. I also checked the
training code again and it looks good to me, but it would be nice if you
can review it.

There are a couple of other classifiers in mallet, it should be trivial to
expose them all to OpenNLP.

Mallet is released under Common Public License

http://opensource.org/licenses/cpl1.0.php

but as you have mentioned, it pulls several dependencies that are
LGPL. These are the dependencies:

  
  org.beanshell
  bsh
  2.0b4


This version is LGPL, however, later versions are APL 2.0

https://github.com/beanshell/beanshell


  jgrapht
  jgrapht
  0.6.0


that version was also LGPL, but it has now been dual-licensed with EPL 1.0

https://github.com/jgrapht/jgrapht/wiki/Relicensing

which could be included also in APL 2.0 projects

http://www.apache.org/legal/resolved.html

 
  net.sf.jwordnet
  jwnl
  1.4_rc3


BSD license, but this library has already been discussed here.

 
  net.sf.trove4j
  trove4j
  2.0.2


LGPL-ed.


  com.googlecode.matrix-toolkits-java
  mtj
  0.9.14


also LGPL

I think moving it to the sandbox will be very nice. I can also help if
needed.  I will check the mallet license.

Thanks

Re: mallet addon

[Joern Kottmann]

Hello,

this doesn't work with the 1.6.0 release, I build it for testing of one of
the first drafts of the machine learning rewrite work we did for 1.6.0.
There have been a few changes afterwards.
Anyway, if you have a need for it I am happy to fix it up. We can also move
it to the sandbox, releasing it at Apache might be more difficult since
mallet pulls in incompatible licensed dependencies. But maybe that changed,
we can check.

What do you think?

Jörn
