Free or open source dictionaries [closed]

Question

I'm working on a multi-lingual search engine. I need to map keywords in English to corresponding words in following languages:

• Bulgarian
• Catalan
• Chinese
• Crotian
• Czech
• Danish
• Dutch
• Finish
• French
• German
• Greek
• Hungarian
• Italian
• Japanese
• Korean
• Lithuanian
• Litvian
• Norwegian
• Polish
• Portuguese
• Romanian
• Russian
• Slovak
• Slovenian
• Spanish
• Swedish
• Thai
• Ukrainian
• Vietnamese

I already know about eudict and stardict. Could you recommend some other free or open source dictionaries which cover one or more of the above languages?

EDIT The dictionaries will be used for translation, but not spell checking.

Answer 1

You might want to look into Hunspell, the spell checker used in Firefox and OpenOffice.

For information about the dictionaries used in these products see here:

Answer 2

In sourceforget.net there are lot of open source libraries. One such project is TransDict. See if http://sourceforge.net/projects/transdict/ fits your need.
