Re: Performances of OpenNLP tools

2016-06-21 Thread Jason Baldridge
Jörn is absolutely right about that. Another good source of training data
is MASC. I've got some instructions for training models with MASC here:

https://github.com/scalanlp/chalk/wiki/Chalk-command-line-tutorial

Chalk (now defunct) provided a Scala wrapper around OpenNLP functionality,
so the instructions there should make it fairly straightforward to adapt
MASC data to OpenNLP.

Re: Performances of OpenNLP tools

2016-06-21 Thread Joern Kottmann
There are some research papers which study and compare the performance of
NLP toolkits, but be careful often they don't train the NLP tools on the
same data and the training data makes a big difference on the performance.

Re: Performances of OpenNLP tools

2016-06-21 Thread Joern Kottmann
Just don't use the very old existing models, to get good results you have
to train on your own data, especially if the domain of the data used for
training and the data which should be processed doesn't match. The old
models are trained on 90s news, those don't work well on todays news and
probably much worse on tweets.

OntoNots is a good place to start if the goal is to process news. OpenNLP
comes with build-in support to train models from OntoNotes.

Maybe we could put the results of the evaluator tests for each component 
somewhere on a webpage and on every release update them.
This is of course provided there are reasonable data sets for testing each 
component.
What do you think?

Re: Performances of OpenNLP tools

2016-06-21 Thread Mondher Bouazizi
Hi,

Thank you for your replies.

Please Jeffrey accept once more my apologies for receiving the email twice.

I also think it would be great to have such studies on the performances of
OpenNLP.

I have been looking for this information and checked in many places,
including obviously google scholar, and I haven't found any serious studies
or reliable results. Most of the existing ones report the performances of
outdated releases of OpenNLP, and focus more on the execution time or
CPU/RAM consumption, etc.

I think such a comparison will help not only evaluate the overall accuracy,
but also highlight the issues with the existing models (as a matter of
fact, the existing models fail to recognize many of the hashtags in tweets:
the tokenizer splits them into the "#" symbol and a word that the PoS
tagger also fails to recognize).

Therefore, building Twitter-based models would also be useful, since many
of the works in academia / industry are focusing on Twitter data.

Best regards,

Mondher
