Nowadays, no one will object to the advent of the information society. In today's information society, the importance of information is ever more increasing, from the individual level to the group and national levels. Accordingly, due to compartmentalization of scientific technology and study, we have experienced production of a gargantuan amount of new information. We have called this nature of the contemporary society the information explosion or information flood. However, even if a large amount of knowledge and information is collected, if it is not understood and organized appropriately, we cannot use the knowledge and information appropriately. We produce professionals who develop processing methods in order to provide the user the best information most quickly and accurately from the pool of exponentially expanding information and who connect the user to the information to find the appropriate information and conduct effective searches.
