E-marketplace has a very important requirement of achieving mutual meaning understanding between sellers and buyers. To meet this requirement, this paper has proposed a novel SD-DSD approach, which enables to disambiguate senses between a sender and a receiver for their sent and received documents. This approach has developed five novel strategies for sense disambiguation. Based on them, new document representation models for message exchange are devised, together with their sense consistency control procedures and sense interpretation evaluation method. © 2010 Springer-Verlag Berlin Heidelberg.
