Subject Re: Korean character set in analysis
Date Thu, 29 Nov 2001 12:47:41 GMT
Hi,

I have made 3 classes for the Simplified Chinese. They are ChineseAnalyzer,
ChineseFilter and ChineseTokenizer. If you are interesting in those, I can
upload.

You can use a dictionary to extract nouns from the sentences.

Cheers!
