Hoi, Andre Engels wrote some further extensions to the pywikipedia bot. It allows you to update the interlanguage links. The way it works is by distinguishing between the wiktionaries that DO capitalise and the ones that do not. When a word exists that is capitalised, it will look for capitalised words only and look for a match. When a wiktionary only has capitalised words, it will not look for the uncapitalised words in that wiktionary.
When you use the software, the file user-config.py contains three lines that contain in my case: mylang = "nl" family = "wiktionary" username = "RobotGMwikt"
The software is used from a prompt: in windows "cmd" You login using the login.py program; it tells you the user it will be using and you will have to provide a password.
Then you run the program by typing interwiki.py -wiktionary -start:! This will do try to find all links in all wiktionaries (bigger than 100 words) from the first onwards. When it finds words with an exact match it will create an interwiki link. It will only update one article a minute in order not to be too big a burden on the database.
I am running it for the nl:wiktionary as I write this. It has updated 59 articles so far and the last one is Arnavutluk a Turkish word. It should run (as a bot) every now and then on all wiktionaries. To make clear that a word that is written inexactly the same way in other wiktionaries.
If you want the software, it can be found on Sourceforge http://sourceforge.net/projects/pywikipediabot/ or you can ask me to send you the ZIP file Andre send me.
Thanks, GerardM
