Figure 4

Representation of argumentative structure within and across publications. The argumentative structure used to justify Meister's claim on the isolation of GS from rat liver (A1) is represented as a series of assertion instances linked by is_directly inferred_from relations. Dashed line separates assertions made in Meister 1985 and Tate 1972. Dashed-dot boxes indicate composite assertions with their component assertions placed inside signifying the has_conjunctive_part relations. Author initials tags of the assertions made by Tate et al. are omitted, as are links to propositions, reports, authors and texts. Color code as in figure 1.
