Representation of assertions with subject and provenance. Assertion instances are related to proposition instances representing the subject of the assertion by asserts, to the agents making the assertion by is_assertion_made_by and to the reports in which they are made by is_assertion_made_in. See text for additional relations among assertions, agents, reports and textual representations. Assertion and proposition labels reflect the graph representation of assertion subjects (see text). Color code of assertion and proposition labels indicates the structured representation of assertion subjects (yellow: class, blue italics: property, red: Manchester syntax restriction keyword). Circle shows the index by which the assertion is referred to in the text.
