Quillian had been attempting to build up a PC program that could understand composed materials, for example, daily papers and course books, at a level of expertise practically identical to that of a normal peruser. Having gained from the disappointments of machine interpretation programs, Quillian understood that so as to have his PC comprehend dialect it was important to issue it a certain measure of world information with respect to the subjects it would be perusing about. There was no chance to get for him to know how this world learning should be spoken to, so he basically proposed a structure that appeared to him to be sensible. Sensible, as in it allowed proficient stockpiling of data (this is vital since PCs have restrictions on their stockpiling limit), and it took into consideration inferential thinking, which appeared to be a fundamental segment of perception. Collins and Quillian then recommended that maybe the structure of semantic memory that Quillian was utilizing as a part of his PC.
