Subject [jira] Commented: (LUCENE-2498) add sentence boundary charfilter
Date Sat, 12 Jun 2010 22:37:13 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12878324#action_12878324

Steven Rowe commented on LUCENE-2498:
-------------------------------------

I wonder if it would be possible/make sense to make this a tokenizer instead of a charfilter:
one token per sentence.  Then token production would be in a filter stage.

> From the discussion of LUCENE-2167:
> It would be nice to have a CharFilter? to mark sentence boundaries.
> Such functionality would be useful for:
> * prevent phrase queries with 0 slop from matching across sentences
> * inhibiting multiword synonyms, or shingles, etc.
> For sentence boundary detection we could use Jflex's support for the Unicode Sentence_Break
property etc,
> and the UAX#29 definition as a default grammar.
> One idea is to just mark the boundaries with a user-provided String.
> As a simple use-case, a user could then add this string to a stopfilter, and it would
introduce a position increment.
> This would inhibit phrase queries, etc.
> a user could use the sentence-markers to do more advanced processing downstream.
