 Frege’s well known response is that both the referent and the sense of a referring term play a role in specifying its semantic content. But what is the sense of a term? Frege’s own way of cashing out the notion of sense is in terms of a mode of presentation (MOP), an idea used by many later philosophers. The MOP of a referring term is the way in which the putative referent of the term is presented to us by our phenomenology. MOPs are what we would use in an attempt to identify or locate the referent of a referring term whose meaning we grasp. Many contemporary theories of meaning that turn on information, incorporate MOPs in one way or another. The reason for this is that although reducing the meaning of a term to the information carried or transmitted by it alone is attractive, it has proven to be fraught.
