Subject [jira] [Commented] (LUCENE-4590) WriteEnwikiLineDoc which writes Wikipedia category pages to a separate file
Date Thu, 06 Dec 2012 09:13:01 GMT


Doron Cohen commented on LUCENE-4590:

bq. Do you think perhaps that EnwikiContentSource should let the caller know whether the returned
DocData represents a content page or category page?

That's what I planned at start, but decided to leave WriteLineDoc intact because it is general,
that is, not aware of the unique structure of Wikipedia data, where some of the pages represent

bq. So maybe, if someone wants to generate a line file from the pages only... flexibility
that I think you are trying to achieve...

Actually I am after the two files... :) These category pages are (unique) taxonomy node names,
but without the taxonomy structure, which can be deduced from the (parent) categories of the
category pages. Having this separate category pages can be useful for deducing that taxonomy.
