The integrating of information from disparate sources with disparate conceptual, contextual, and typographical representations is known as information integration (II). Information integration usually refers to textual representations of knowledge, but it may also relate to rich-media content. Textual representations are easy to integrate because they can be processed by a computer. Rich-media representations are even easier to integrate because they can be manipulated by software applications. Integrated information is the set of relationships that connect all the information contained in a complex system. Integrated information allows us to understand how the parts of the whole are connected and how they influence each other. Integrated information has three essential properties: unity, compositionality, and autonomy. Unity implies that the different aspects of a phenomenon are interrelated; compositionality means that the whole is more than the sum of its parts; and autonomy means that the elements of an organization are independent of one another. In biology, the concept of integrated information has been applied to organisms. Unity in organisms is shown by their tendency to evolve as a coherent unit; compositionality is demonstrated by the fact that the anatomy, physiology, and behavior of an organism are not merely the sum of their parts, but are mutually influencing factors that work together to produce the full organism. Autonomy is seen in the fact that organs develop independently of one another within the organism and are able to function properly despite being separated from other organs.
