Hebrew spell-checking in OpenOffice

2010-11-02 Thread Nadav Har'El
Recently I noticed that (thanks to Lior Kaplan, it seems) it is now trivial
to get Hebrew spellchecking (based on Hspell 1.1) in OpenOffice.
The Hebrew localized version (now available on the official OpenOffice site!)
comes with Hebrew spell-checking pre-bundled, and there's an extension [1]
for those who use the English version of open-office.

However, when I actually used this spell checker, and observed my wife using
it, I noticed two annoying problems in the way it works. I'm not sure if these
are OpenOffice problems per se, or perhaps problems that should be solved in
the context of hunspell, OpenOffice's spell-checking library. It is possible
that changes to the dictionary file is all that is needed to solve these
problems, but it is also possible that OpenOffice code needs to be changed.
I simply don't know I was hoping that someone here could help me figure this
out, or at least point me to the right place to report these problems.

The first issue is acronyms (rashei tevot) and abbreviations. In Hebrew,
these use the geresh and gershaim (or single or double quotes), which is
part of the word. OpenOffice does not understand that these quotes are part
of the Hebrew word, and splits the word on them. As a result all acronyms are
marked as spelling mistakes. This is really annoying, especially for certain
types of documents where acronyms are common.

The second issue is the correction suggestions for spelling errors. All
the suggestions indeed appear to be valid words, but their order is
terrible - it appears little or no attention was paid to trying to provide
the most likely suggestions first. The screenshot on the extension page [1]
provides an excellent example: When given the mis-spelling עיברי, rather than
provide the most likely suggestion first - עברי, it is given as the 8th
suggestion, and the first suggestions are highly unlikely. The sixth
suggestion is especially unlikely (requiring one accidental transpose and one
movement): ערביי. I'd like OpenOffice to use common-sense edit-distance
based heuristics to decide which suggestion to give first (i.e., one typing
mistake is more likely than two), but also Hebrew-specific rules regarding
the cost of these edits, e.g., that in Hebrew omitting or adding a vowel
(em kri'a) is more likely than omitting or adding just any random letter.
Hebrew also has letters that sound the same (e.g., tav and tet) or close,
and a bunch of other rules I'd like to see.
I believe that hunspell's dictionary in fact has a way to give such correction
rules, but I don't know how to correctly write them, or how to make OpenOffice
use them.

I (and thousands of other OpenOffice users in Israel) would be grateful
if someone could look into these issues.

Nadav.

My pleasure (:

It's available only as the 3.3 RC releases, and will be available on the
final release.

Known issue, and reported at

It is marked for work during the 3.4 release.

The word list in the extension is created with myspell's format. Hunspell
should be similar but I couldn't build that format at the time. The builds
were done as part of the debian hspell package which I maintain.

Please let me know if you need help creating a hunspell-format dictionary
from Hspell (it shouldn't be difficult - basically make hunspell should
do it).

OpenOffice loads the hunspell-format dictionary (with so-called double
affix compression) *much* faster than it does the old myspell format,
which fixes the old lockup-for-many-seconds-while-loading-the-hebrew-
dictionary bug (see http://qa.openoffice.org/issues/show_bug.cgi?id=66939).

So it is actually important that you use the hunspell target, not the
myspell target, in your packages.

I guess we need to. Does anyone on this list have any experience with those?

In particular, can one of these keywords be used to say that inserting

It did not get into hspell 1.1, but if you append the following lines to
hunspell's .aff, you get some soundlikes (Fedora and RHEL6 have it though)
I did not find a means to convey the lightweight of yod and waw in thunspell(4).
It sounds as a reasonable feature request, though.

 I've double checked this, and Debian doesn't include a tool needed for

I see :(

However, if we're talking about the OpenOffice package, not the debian
package, you're not really constrained by what is available on Debian.

 The solution to #66939 was providing the dictionary in UTF8 instead of
 iso-8859-8 encoding. The freeze by oo.org was actually a conversion to
 UTF-8.
 
 Hunspell might be faster than myspell, but the difference is minor comparing
 to the UTF8 conversion. At the moment oo.org loads the dictionary in less
 the 1 sec.

Oh, sorry. I guess I remembered it wrongly.

You're right. I checked on my system, and the myspell-format dictionary takes
0.3 seconds to load, while the hunspell-format takes 0.1 seconds. Not a
dramatic difference. The uncompressed size of the hunspell format is half
that of myspell - again, not dramatic. I think the difference in memory use
is more dramatic (9 MB vs. 36 MB in a test I just did).

I never understood the UTF-8 problem, by the way. Was this bug ever fixed?
No encoding conversion should have ever been this slow. Even if they would
pipe to an external iconv process, it would still have been 100 times
faster ;-)

I'm constrained as I work (and package) on Debian. But I'll take the
dictionary files from the Fedora RPM. I'll update you when a new extension
will be ready and we'll test it.

Are you interested in processing horsepower, or storage?

The closest thing to server in the ARM world is probably a NAS box. See 
arch/arm/mach-kirkwood/Kconfig in a recent kernel for a list of some things, 
including QNAP and LaCie offerings. Since these are all ARMv5 chips with VIVT 
cache, their processing capabilities are seriously limited.

chrooted postfix in debian and mysql

 the howto), but now I have postfix refusing to connect to the database.
 I'm close to open a new thread on that since I feel like I exhausted
 everything Google could find me.

Motherfrakker! This took two important hours and here's the solution:

postfix kept complaining the socket was not there but it is. finally I
saw that one example listed the map setting in main.cf thus:

virtual_alias_maps = proxy:mysql:/etc/postfix/mysql_virtual_alias_maps.cf
rather than:
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf

As most of the faqs do. I did grep chroot /etc/postfix/* and discovered
that master.cf indeed defaults all the services to chroots (not a bad
idea at all) but not the proxymap. indeed if you look at the postfix
processes in /proc you will see that most interesting bits do run
chrooted. the solution was not to move the socket into the chroot, but
instead to use the proxy: to get to it.

methinks this and other bits of the process mean the howto needs a
serious update. If only I had the time :-)

 Hi,
 Why don't you take Atom processors?

Because I want to run experiments on the ARM architecture.

Cheers,

Get yourself an old openmoko device. They are ARM based, well documented,
with several simple options of Linux distros for them. Very weak, of course,
but for ARM games (playing with your arm :-) ) they should be just fine.

Re: looking to buy ARM servers

As written earlier, the cheapest way to get an ARM is to buy a Seagate
FreeAgent Dockstar at 300 NIS.
 This is basically a slightly trimmed down SheevaPlug.

128MB RAM
128MB NAND Flash
3 USB ports
Fanless
debian  OpenWRT available.

Please see:

Also look at the Amazon page for the product:
http://www.amazon.com/Seagate-FreeAgent-DockStar-Network-STDSA10G-RK/dp/B002MRRU6G
It seems that the pogoplug service is now free for life, or so says one of
the Amazon user reviews.
