Re: CoReference
Few days ago went to look at an old issue to see if I could perhaps write some docs for it, but I think the coref module is not in the sandbox. Here's the issue in question https://issues.apache.org/jira/browse/OPENNLP-48 and here's where I believe the code is now located https://svn.apache.org/repos/asf/opennlp/sandbox/opennlp-coref/ Not sure if there was any other work not mentioned in that issue.

Re: How to work with Coreference resolutions
Jörn,
Great, that helps quite a lot! It is similar with the main method of that
class but your explanations and the trick of integrating the NERs are the
real silver bullet of your post here. Thanks a bunch.
I will play with that at night.
What I want is to define a few IE algorithms from that.
Is there any references of Information Extraction using OpenNLP that you
would recommend as well?
Thanks,
Carlos.

Hello,
the input for the coreference component needs to be preprocessed,
with the sentence detector, tokenizer, parser and name finders.
You can do this via API and our documentation provides sample code for
each of these steps.
The only tricky part is the to get the named entities into the parse tree.
Here is a sample:
Parse parse; // returned from parser
Span personEntites[]; // returned from person name model
Parse.addNames(person, personEntites[fi], parse.getTagNodes());
After this the person names are inserted into the parse tree, you need
to repeat this step for every entity type you would like to reference. The
person
tags are currently hard coded. You can find a list in
TreebankNameFinder.NAME_TYPES
(I believe thats a trunk only class).
Before you start with the rest you should download all the coreferencer
models for 1.4
into one directory, similar to the structure on the sever.
Now we are coming to the coreference resolution code:
Linker treebankLinker = new TreebankLinker(/home/joern/**corefmodel/,
LinkerMode.TEST);
This will create the linker for you.
First all the mentions need to be recognized and afterward they are linked
together.
For every sentence you do this:
Parse p = ...; // contains a parse of a sentence with names
Mention[] extents = treebankLinker.**getMentionFinder().**getMentions(new
DefaultParse(p,sentenceNumber)**);
for (int ei=0,en=extents.length;eien;**ei++) {
if (extents[ei].getParse() == null) {
Parse snp = new Parse(p.getText(),extents[ei].**getSpan(),NML,1.0,0);
p.insert(snp);
extents[ei].setParse(new DefaultParse(snp, sentenceNumber));
}
}
sentenceNumber++;
The result are the mentions per sentence. All these mention objects should
be copied into a single list,
e.g. via document.addAll(extents) (document is of type ListMention).
Now the mentions of one document can be linked together:
DiscourseEntity[] entities = treebankLinker.getEntities(**document.toArray(new
Mention[document.size()]));
The entities array now contains the various detected and linked entities,
usually you want to filter out entities
which just have a single mention. The DiscourseEntity groups mentions
together, a mention must not be an
entity, other noun phrases are valid mentions as well.
Hope that helps,
Jörn

Jörn,
I just want to know how it works for now. I've following the one from
StanfordNLP as well.
Basically, I want to first know if I just pass raw test to it or if I have
to tag that first. Looks like I need to do POS tag first.
I want to be able to pass a text and get the references as object lists
from the API.
So I can fetch the relations.
I still need to take some time here and read more the source code unless
you have some pointers.
Thanks,
Carlos.

Thats still work in progress, on which data do you want to train?
You need to produce data in a certain format, there should be a sample in
the test folder.
Its basically penn treebank style plus some nodes to label the mentions
in the tree.
The parse trees of a document are grouped and send document wise
to the trainer via a stream. After this is done a new model will be
trained.
The OpenNLP corferencer works currently only on noun phrases, other
mentions
like verbs will not be resolved (in case you wanna train on OntoNotes).
