Mark Miller commented on LUCENE-1758: ------------------------------------- Its not released, but Arabic Analyzer has been around long enough thats its certainly in use by at least a couple people - lets be very explicit in the contrib changes (which I'm sure non of these users will read ;) ) about the lowercase compat break. > improve arabic analyzer: light8 -> light10 > ------------------------------------------ > > Key: LUCENE-1758 > URL: https://issues.apache.org/jira/browse/LUCENE-1758 > Project: Lucene - Java > Issue Type: Improvement > Components: contrib/analyzers > Reporter: Robert Muir > Assignee: Robert Muir > Priority: Minor > Fix For: 2.9 > > Attachments: LUCENE-1758.patch, LUCENE-1758.patch, LUCENE-1758.txt > > > Someone mentioned on the java user list that the arabic analysis was not as > good as they would like. > This patch adds the لل- prefix (light10 algorithm versus light8 algorithm). > In the light10 paper, this improves precision from .390 to .413 > They mention this is not statistically significant, but it makes linguistic > sense and at least has been shown not to hurt. > In the future, I hope openrelevance will allow us to try some more > approaches. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
