1. A method that utilizes a processor to detect a rapid increase keyword, the method comprising:
- generating, using the processor, rapid increase standard quotient information comprising an input number threshold to detect a rapid increase keyword by using input number information for a keyword, the input number information being related to a first number of inputs of the keyword as a search term by users for time intervals;
generating subsequent input number information for the keyword based on a second number of inputs of the keyword as a search term by users for a subsequent time interval;
comparing the subsequent input number information with the rapid increase standard quotient information to determine whether the second number of inputs exceeds the input number threshold of the rapid increase standard quotient information;
generating input rank rise information by calculating a difference in ranks for the keyword in terms of input numbers for a time interval; and
identifying the keyword as a rapid increase keyword based on a determination that the second number of inputs exceeds the input number threshold and based on a rapid increase quotient obtained by applying a weight variable to at least one piece of the input number increase information, the input rank rise information and the rapid increase standard quotient information.

Abstract
The present invention relates to a method and system for detecting a keyword whose number of being inputted from a user terminal is rapidly increased, and more particularly, to a method and system which generate rapid increase standard quotient by using the average and standard deviation for each keyword and compare the rapid increase standard quotient with measured input number in order to detect a keyword whose input number is rapidly increased.
