Uwe Schindler commented on LUCENE-1629:
---------------------------------------
I did some checks now, it is the problem of the ant script. Because of this,
e.g. ArabicAnalyzer throws an IOException (but this is not tested, and so no
test failures occur).
The ant script should copy all the data files to the build/classes directory
after compiling and before jaring.
I do not know, how to fix this correctly, because I do not fully understand all
the parts of the build files and how maven and common-build.xml works together
with contrib-build and so on.
The simpliest would be to customize the "compile" target for the analyzers
package and list there all files that must be copied during the compilation
step.
Should I open an additional bug report for the ArabicAnalyzer, or should we fix
the build.xml for analyzers with this case?

> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/analyzers
> Affects Versions: 2.4.1
> Environment: for java 1.5 or higher, lucene 2.4.1
> Reporter: Xiaoping Gao

> I wrote a Analyzer for apache lucene for analyzing sentences in Chinese
> language. it's called "imdict-chinese-analyzer", the project on google code
> is here: http://code.google.com/p/imdict-chinese-analyzer/
> In Chinese, "我是中国人"(I am Chinese), should be tokenized as "我"(I) "是"(am)
> "中国人"(Chinese), not "我" "是中" "国人". So the analyzer must handle each sentence
> properly, or there will be mis-understandings everywhere in the index
> constructed by Lucene, and the accuracy of the search engine will be affected
> seriously!
> Although there are two analyzer packages in apache repository which can
> handle Chinese: ChineseAnalyzer and CJKAnalyzer, they take each character or
> every two adjoining characters as a single word, this is obviously not true
> in reality, also this strategy will increase the index size and hurt the
> performance baddly.
> The algorithm of imdict-chinese-analyzer is based on Hidden Markov Model
> (HMM), so it can tokenize chinese sentence in a really intelligent way.
> Tokenizaion accuracy of this model is above 90% according to the paper
> "HHMM-based Chinese Lexical analyzer ICTCLAL" while other analyzer's is about
> 60%.
> As imdict-chinese-analyzer is a really fast and intelligent. I want to
> contribute it to the apache lucene repository.
