User experienced quality estimation apparatus, terminal bottleneck determination apparatus, similar operation extraction apparatus, method and program

A user experienced quality estimation method for estimating a user experienced waiting time of an application in an user terminal, comprising:

• a data reception in which a data reception unit obtains, 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 stores the estimation target logs in a received log storage unit;
• a log exclusion in which a log exclusion unit reads out the estimation target logs from the received log storage unit, and outputs 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 in which a quantization unit calculates, as multiplicity, the number of processes in a timeslot of a constant time length for the logs output from the log exclusion;
• and
• a continuous region extraction in which a continuous region extraction unit extracts a continuous region from data quantized by the quantization, wherein the continuous region is a time length formed by continuous time slots,
• wherein the continuous region extraction includes:
• a first continuous region extraction of extracting the continuous region without distinguishing between processes of the data obtaining, the script execution and the screen rendering, or
• a second continuous region extraction of extracting the continuous region by distinguishing between processes of the data obtaining, the script execution and the screen rendering.
