USER SENSORY QUALITY ESTIMATION DEVICE, TERMINAL BOTTLENECK DETERMINATION DEVICE, SIMILAR OPERATION EXTRACTION DEVICE, AND METHODS AND PROGRAMS THEREFOR

摘要

A user experienced quality estimation apparatus for estimating a user experienced waiting time of an application in an user terminal, includes: a data reception unit configured to obtain, as estimation target logs, a duration time of each process of data obtaining, script execution and screen rendering performed in an estimation target period in the user terminal, and to store the estimation target logs in a received log storage unit; a log exclusion unit configured to read out the estimation target logs from the received log storage unit, and output logs from which logs having data duration time shorter than a predetermined short time process threshold or longer than a predetermined long time process threshold are excluded; a quantization unit configured to calculate, as multiplicity, the number of processes in a timeslot of a constant time length for the logs output from the log exclusion unit; and a continuous region extraction unit configured to extract a continuous region from data quantized by the quantization unit.
