Based on this discussion, the dissertation attempts to establish a framework for translation from a sociosemiotic perspective, emphasizing that Peirce's triadic division of a sign can be used to explicate translation in a macro point of view and that Morris's famous three types of meaning can be applied to the actual translation practice. From this, it can be clearly shown that a sociosemiotic theory is a sound one in its application to translation.
