The emerging structures

A complex system often consists of components that weakly interact with each other but are not negligible. Simon named such a system near decomposable system and proposed the propositions of near decomposability, which interprets the behaviors of many complex systems. The underlying assumption is that all observers share a unified cognition paradigm: bottom-up aggregation. This chapter extends the research object to a dual system consisting of the observed complex system and the memory of the system, proposes new propositions considering the integrity of representation and a semantic emerging structure, verifies the propositions and the emerging rules through text summarization, and proposes new principles regarding text as a near decomposable system. The structure of text emerges with representing components independently and linking components with rules. The study of emerging near decomposable structure provides a new way to understand text, summarization and the near decomposability.
