Experimental Methods (Part II) Classification of Natural Language Messages

New Media  | 23 de octubre de 2012  | Vistas: 58

In this lecture, Daniel Houser deals with the function language has as a device to impact economic exchange and talks about the reasons of its outcome, stating that certain types of messages can make a great difference in the recipient of the information. He lists several reasons to the results like making promises, discussing benefits, convincing, persuading, and sharing possibilities that will eventually lead to economic transactions; and also, the methods people use when deciding what interpretation will be given to messages, consequently, referring to the classification of natural language. For a better understanding of the process, Houser concludes by providing desirable elements to be present in the categorization of communication, such as science, robustness, and accuracy.
