Abstract:
1. A method in a computing device for analyzing time dependency of a query, the method comprising: storing frequency of the query at each of a plurality of intervals, the frequency for an interval indicating number of times the query was submitted during that interval; calculating by the computing device values of a frequency spectral for each of a plurality of angular frequencies of the query based on the stored frequency of the queries at each of the plurality of intervals based on the following equation: determining by the computing device whether the values of the frequency spectral include peaks wherein a peak is a locally maximum value of the frequency spectral within a range with a property as represented by the following: after determining that the values of the frequency spectral include no peaks, indicating that the query is time-independent; and after determining that the values of the frequency spectral include a peak, indicating that the query is time-dependent; and wherein time dependency of the query based on the determination of whether the frequency spectral includes peaks.
