[jira] [Comment Edited] (LUCENE-3922) Add Japanese Kanji number
normalization to Kuromoji
[ https://issues.apache.org/jira/browse/LUCENE-3922?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13474257#comment-13474257 ]

Hi Christian,
That's what I am thinking. I think TokenFilter would be a good choice to implement that feature. We can use POS tag to recognize what a token is. We can apply normalization if a token is a numeral prefix/suffix with numerals.

> Japanese people use Kanji numerals instead of Arabic numerals for writing price, address and so on. i.e 12万4800円(124,800JPY), 二番町三ノ二(3-2 Nibancho) and 十二月(December). So, we would like to normalize those Kanji numerals to Arabic numerals (I don't think we need to have a capability to normalize to Kanji numerals).
