An interesting August 3, 2010 Wall Street Journal article titled "Microsoft Mines Web to Hone Language Tool" about how Microsoft is mining the web for data to buildup her Engkoo.com Chinese web dictionary.
Eventually it'll include machine generated dictation of sample sentences and even machine generated videos of sentences being spoken so that language learners with see the movement of the lips when the words are spoken.
The focus so far is for Chinese learners of English but might eventually go the other way as well.
Plans are also in the works for other languages such as Japanese and English.
I wonder why it's Engkoo and not Yingku?
