Description Andrew Dunbar 2007-01-16 02:45:14 UTC
DidYouMean is designed for the English Wiktionary to automate the use of the
{{see}} template there which links articles whose titles differ only by
capitalisation, use of diacritics, spaces, hyphenation, apostrophes, etc.

It adds two metadata tables which are maintained by hooks in all places where
articles can be created, renamed, or deleted. Metadata is kept only for
non-redirects in the main namespace.

A list of links to "similar" articles is added to all articles pages in view
mode and also to the 'nogomatch' and 'noarticletext' pages.

Comment 4 Connel MacKenzie 2007-01-16 05:20:08 UTC
Since en.wiktionary.org (and presumably others) have [Appendix:Names] and all
those name entries, were you planning on adding any other name-oriented
normalizing to this?  Or is SOUNDEX the next phase?
Comment 5 Andrew Dunbar 2007-01-16 07:11:18 UTC
Handling appendices would require parsing whole pages which is more complex than
just parsing the {{see}} template.

Soundex turned out to be a lot more promiscuous than I expected. It seemed to
only take into account the first part of the words resuling in enormous lists of
matching words for each word and not being as alike as you'd expect.

Metaphone should be better but I couldn't get the library to work in the account
you gave me.

I'd been thinkig about anagrams and textonyms next but a) they are
language-dependent, and b) they require parsing and replacing whole sections of
articles which as often as not are not in any well-defined format.

Another idea is to scan all redlinks and possibly blue links except that they
won't have canonical casing and there is no easy way to sort the wheat from the
chaff akin to ignoring redirects in article space.
Comment 6 Connel MacKenzie 2007-01-16 07:15:30 UTC
Well, I meant for the resulting main namespace entries, not taking apart the
Appendices themselves.
Comment 7 Rotem Liss 2007-01-16 07:36:27 UTC
Please add wikibugs-l@wikipedia.org to the CC list when you assign the bugs.
Comment 8 Rob Church 2007-01-18 08:21:33 UTC
First impressions are that this is quite a neat little extension and could have
great potential use. The "did you mean" message itself needs to be more
obtrusive - think coloured boxes - it's almost invisible on a search results page.
Comment 9 Andrew Dunbar 2007-01-18 11:35:23 UTC
Thanks Rob. The idea was that on the English Wiktionary it will just look like
what we've already been doing for ages without all the manual labour. Once it's
out there people should modify it to do something bigger on the search page, and
maybe not ignore redirects for Wikipedia like it does for wiktionary.

Fixed a regression that slipped in.
Comment 15 Brion Vibber 2007-02-09 06:04:19 UTC
Committed the current version to extensions in r19837 to make it a little easier
to work with updates while testing.
Comment 16 Brion Vibber 2008-03-28 23:16:15 UTC
A few notes on current state of the extension...


Setup:

* Should use update hooks so the table can get installed by standard update.php
* install.php should be replaced with a script that simply allows rebuilding the normalization entries


Caching:

* 'see also' bits embedded into pages won't be automatically updated when the page is already cached. For cache-correctness, it'll need to look up affected pages on addition/removal of normalization entries and schedule them for purges (and, possibly, link refresh)


Internationalization:

* It's hardcoded for particular English templates, which seems a bit icky.


In general I'm not too comfortable with the way it messes about with the text of pages as they're parsed. A totally separate 'similar pages' UI component might be cleaner. *shrug*

Marking "reviewed" as the extension has been reviewed by Brion in comment 16.
Comment 19 Sumana Harihareswara 2012-11-16 22:02:11 UTC
I've removed DidYouMean from https://www.mediawiki.org/wiki/Review_queue until the author responds to comment 16 .
Comment 20 Andre Klapper 2014-02-28 15:00:54 UTC
Andrew Dunbar: Resetting the assignee and status of this issue because there has been no progress in the last years. Feel free to take it again when you are actually planning to fix this. Thanks.
