Biography as Scenario: Representing Historical Knowledge by the Event Bush

Event Bush Method

The method of event bush was developed by Pshenichny et al. (2009) to reveal the behavior of information in dynamic environments of directed alternative changes (Pshenichny and Kanzheleva, 2011). It is gaining increasing importance in a variety of fields, from the geosciences to marketing and history (Solomin and Mandrik, 2015). For detailed description of the method, the reader is referred to these publications.

In brief, the event bush represents an environment of directed alternative changes as a set of events of four types: primary internal (ia), primary external (ib), secondary (ii) and tertiary (iii). Event is defined as a statement of general form S – P₁, P₂, …, P_i, where S is subject, and P₁, P₂, …, P_i are predicates, with or without negation. The following restrictions are put herewith, (i) subject may be only one in any event, (ii) subject may not be negated, (iii) all predicates may not be negated in an event, at least one must be without negation (e.g., an event S – ~P, ~ being the negation, is not allowed).

The following pairwise relations between event types (i) - (iii) are set in the event bush:
