In e-business, semantic document exchange is a methodology of providing exchangeable semantic documents, which ensures users and computers to share a same understanding in meaning on any exchanged document across heterogeneous contexts. Two kinds of Pinyin input method for word senses such as Word-based input method and Sentence-based input method are proposed. These two kind of word sense based Pinyin input method is based on the statistic language model of word sense representation and disambiguation. The prototype system shows both our Word-based and Sentence-based word sense Pinyin methods are promising in the semantic document editing system. These two kinds of Pinyin input methods of word senses are designed for our semantic document edit system for the semantic document exchange in e-business.
