The world is rich with diversity constraints. Without limitation of the diversity the world would be completely chaotic. The restriction of diversity corresponds to a reduction in the amount of information, therefore, the restriction of diversity is equivalent to the established in statistical theory the concept of redundancy. Redundancy is the more limiting of diversity. If the elements in a set are the same, the redundancy is equal to one. If the box all the balls are the same color, the color redundancy equal to one, if all balls are different colors then the redundancy is zero. The presence of information quality is the need to classify information. Distinguish basic information, i.e. information in inanimate nature, biological, logical, human, or social. For social information is characterized by the allocation of two aspects: semantic, associated with the content of the message, pragmatic, associated with the utility of their recipient.
