The Internet has become a very popular platform for communication around the world. However because most modern computer keyboards are Latin-based, Asian language speakers (such as Chinese) cannot input characters (Hanzi) directly with these keyboards. As a result, methods for representing Chinese characters using Latin alphabets were introduced. The most popular method among these is the Pinyin input system. Pinyin is also called ”Romanised” Chinese in that it phonetically resembles a Chinese character. Due to the highly ambiguous mapping from Pinyin to Chinese characters, word misuses can occur using standard computer keyboard, and more commonly so in internet chat-rooms or instant messengers where the language used is less formal. In this paper we aim to develop a system that can automatically identify such anomalies, whether they are simple typos intentional substitutions. After identifying them, the system should suggest the correct word to be used.
