A cross-language question answering system includes a server which hosts a plurality of community question answering (CQA) websites for different countries. The websites can generate a graphical user interface on an associated user terminal. A machine translation system translates a user question from a first language into a second language. The system may alert the user to similar questions posted on other CQA websites in other languages. The system may post the translated question on another CQA website and notify the user of answers to the translated question that are posted on the website by other users. The system may include memory which stores a plurality of archives, each including questions and answers posted on a corresponding one of the CQA websites. The system may allow a user to enter a query in the user's language and receive responses to the queries retrieved from the archives of other CQA websites.
