[Corpora-List] number and dates normalization

[Gregory Marton]

Hi Shachar,

Also of note for dates:

datejs: http://www.datejs.com/
"An open-source Java-Script Date Library"

joda: http://joda-time.sourceforge.net/
"Joda-Time provides a quality replacement for the Java date and time 
classes. The design allows for multiple calendar systems, while still 
providing a simple API. The 'default' calendar is the ISO8601 standard 
which is used by XML. The Gregorian, Julian, Buddhist, Coptic, Ethiopic and 
Islamic systems are also included, and we welcome further additions. 
Supporting classes include time zone, duration, format and parsing."



It's a little awkward, but for "fifteen hundred" and the like, you can use 
a service of ours.  open a tcp connection as shown below, type "fifteen 
hundred" and hit return, and you'll get a data structure you can read:

$ telnet malta.csail.mit.edu 8009
Trying 128.30.44.123...
Connected to malta.csail.mit.edu.
Escape character is '^]'.
fifteen hundred
((number "fifteen hundred" :span (0 15) :value 1500 :notation natural))
Connection closed by foreign host.

If you do end up using that final interface, please let me know so I can 
make it robustly available on a more sensible name like 
numeric-normalizer.csail.mit.edu or such.  The particular server is 
otherwise liable to change.  I'm also happy to make its source available.

Best,
Grem
