 Theoretical efforts like these set the direction for research to go early in the lifetime of a field of study, and are crucial to the growth of the field.Structural information about languages allows for the discovery and implementation of similarity recognition between pairs of text utterances.For instance, it has recently been proven that based on the structural information present in patterns of human discourse, conceptual recurrence plots can be used to model and visualize trends in data and create reliable measures of similarity between natural textual utterances.
