How is that done?

I see. This is probably of no use for spellchecking, but it is for
postagging.
It gives no suggestions, but it can be used for avoiding false
positives in spellchecking, if you set that tagged words are to be
ignored.
Does
Abu Dhabi NPCNG00
cause both words to be tagged with that tag, or are they
considered 1 token with that postag?
Tokenization is not changed. In this case:
<token postag="<NPCNG00>">Abu</token>
<token postag="</NPCNG00>">Dhabi</token>
if there are more than two tokens, the inside tokens are not tagged.
Perhaps this should be optionally changed (ie, tag the inside tokens too).

Jaume
(Might come in handy for just this tagging..)

Hi, Ruud.
I don't find any documentation. It is used in Polish, French,
Catalan, Russian, Ukrainian and Spanish.
Implementation:
Enable it (Java).
Create a "multiwords.txt" in your resources folder like these
[1]. The tokens are separated by white space and the tag is
separated by a tab.
Result:
The first token of the multiword is tagged with "<POSTAG>" and
the last token is tagged with "</POSTAG>".
The MultiwordChunker is case-insensitive. I would like to make it
configurable, specially for first letter uppercase.

Jaume

Jaume, thanks, but I am not sure.
Depends on its implementation I think.
Where can I find more info?

We don't agree. There is a spellchecker, but also a
single word ignore
list for it.
There are XML rules, but also a Simplereplace rule, a
compounding rule.
So apart from the hammer and the screwdriver, there are
more tools.
There is indeed another tool for multi-words. It seems that
Ruud doesn't know it.
We can enable a HybridDisambiguator and add a
MultiwordChunker to the disambiguation. With this you can
write a list of "multi-words" with its corresponding tag in
a plain text file (multiwords.txt).
I use the MultiwordChunker with two objectives: improve
disambiguation and avoid spelling matches in multiwords.
Would it be useful for you, Ruud?
Regards,
Jaume
But anyway, adding the most frequent ones tot the
disambiguator works.
Getting rid of wrong postags and 10% reported possible
spelling errors on
the entire corpus is a higher priority.
And fixing false positives. Having almost doubled the
amount or rules is
enough for this month.
