Abstract:
1. A computer readable non-transitory storage medium storing a keyword management program which makes a computer perform a keyword management method for managing keywords used when a user terminal connected to a network accesses contents, the keyword management program makes the computer perform the method comprising: calculating a first Burst value indicating an increase per unit time of a keyword; performing a morphological analysis in which a computer extracts the same morpheme as a morpheme stored in a user dictionary table from the contents and obtains attribute information corresponding to the extracted morpheme from a morphological-analysis-result management table, of a text included in the contents based on a keyword having the first Burst value equal to or higher than a threshold; calculating a second Burst value indicating an increase per unit time of a keyword for the keyword obtained as a result of the morphological analysis; calculating an overall Burst value using the first Burst value and the second Burst value by correcting the first Burst value based on characteristics in the contents of the keyword corresponding to the first Burst value; extracting from the contents, a relevant keyword related to the keyword corresponding to the overall Burst value based on time series changes of the overall Burst value, and outputting the keyword and the relevant keyword associated with each other to the user terminal; and classifying the keyword corresponding to the overall Burst value into one of plural, previously-prepared types based on the time series changes of the overall Burst value, by calculating time series changes in the overall Burst value for a past certain period calculating a differential value of the calculated time series changes at a plurality of points in time, and determining a type based on the differential value at each point in time, wherein when outputting the keyword and the relevant keyword associated with each other to the user terminal further outputting a classification result obtained as a result of keyword classification to the user terminal.
