A display information generation device includes an importance calculation unit (111) and a display information generation unit (112). The importance calculation unit receives at least one user object for at least one user (U), a plurality of speaker objects for a plurality of speakers (S1, S2) having a conversation with the at least one user, and a plurality of annotations with respect to each object generated for the at least one user object and the plurality of speaker objects, and calculates importance of the conversation between the one user and each of the plurality of speakers based on at least one of the plurality of speaker objects or the plurality of annotations. The display information generation unit determines a display form of each of the plurality of annotations generated with respect to the plurality of speaker objects based on the importance of the conversation, and generates display information on the plurality of annotations each having the display form.
