Yep, this just comes from having a release

How about releasing the .nbin model files as a separate release from
the binaries. They change much less frequently than the source code and
they are big files, so it makes sense to prevent people from having to
keep downloading the same model files each time we do a new release of
library dlls etc.

The settings file wouldn't be for the library - it would be for the
example executables. The library (should be) designed so you can use
models in any format supported by SharpEntropy, not just the .nbin
versions. I think we need to add an app.config to ToolsExample and
ParseTree, then change the constructor of Mainform.cs in each case to
read the mModelPath from the app.config rather than the hardcoded
string. Best to keep the setting name in app.config consistent; call it
ModelPath. (Which reminds me, we should stick to the naming conventions
for variables etc. that I have established in the code; it took me a
long time to change all the variable names from the Java ones to make
them more readable and consistent with Microsoft's .NET guidelines and
FxCop. The one wrinkle is using the "m" prefix on class-level variables
to distinguish them from local ones. This is the convention we use at
my workplace, so that's why I used it. I haven't done the FxCop sweep
for the coreference code, so expect a lot of variable name changes -
and changes generally - to that part of the code over the next few

Well, that's good news. I am still aware of the nasty SharpEntropy bug
that makes the Smoothing option for training not work. Tell me some
more about the problem with the Parser.

I would prefer not to release the version with half-finished
coreference tool. Could we release the .NET 2.0 binaries that I provide
currently via the CodeProject article, and then do a release with
coreference included in a few weeks' time?

Talking of minor details, do you have any time to look into using
Sandcastle to produce .NET 2.0 documentation, now that the NDoc person
has decided not to do an NDoc for .NET 2.0?

Thanks for copying across my message from the SharpNLP Google group to here.

Did you have any comments on any of the things I wrote?

This brings up another question regarding the config files: if the models are stored in a database, how do we store it in the config files? A "file://" / "sqlite://" prefix maybe?

I'll look into the rest of the stuff as soon as I've got a stable internet connection probably a week, or so

Sqlite is file-based, so a file path to the Sqlite database would work fine. There would be an issue, however, if I put in my code to use SQL Server as the model store, because then you would need the database connection string. These issues would be handled by the client application, however, not the OpenNLP or SharpEntropy libraries. The OpenNLP library will just take a GisModel object; it doesn't care how that object was constructed or the internals of where it's getting its data from.
