Abstract

A computer-implemented method for detecting a repetitive activity pattern is disclosed. The method may include receiving activity data. The activity data may include timing information of a plurality of events. The method may also include determining a series of interval times associated with the plurality of events. The method may further include calculating a series of single standard deviations representing a running standard deviation of the series of interval times. The method may also include calculating a double standard deviation of the series of single standard deviations. The method may yet further include detecting a repetitive activity pattern if the double standard deviation is below a first pre-determined standard deviation threshold for a time period longer than a time threshold.

Claims

1. A computer-implemented method for detecting a repetitive activity pattern, the method comprising:

receiving activity data, wherein the activity data include timing information of a plurality of events;

determining a series of interval times associated with the plurality of events;

calculating a series of single standard deviations representing a running standard deviation of the series of interval times;

calculating a double standard deviation of the series of single standard deviations; and

detecting a repetitive activity pattern if the double standard deviation is below a first pre-determined standard deviation threshold for a time period longer than a time threshold.

2. The method of claim 1, further including detecting a repetitive activity pattern if the single standard deviation is below a second pre-determined standard deviation threshold for a time period longer than the time threshold.

3. The method of claim 1, wherein determining a series of interval times includes:

sorting the activity data in a chronological order; and

determining each interval time as the temporal distance between every two consecutive activity data.

4. The method of claim 1, further including indicating the detected repetitive activity pattern to a user via a display interface.

5. The method of claim 4, further including:

receiving an input from the user, wherein the input includes a permission to remove the repetitive activity; and

removing activity data that correspond to the repetitive activity from the activity data.

6. The method of claim 1, further including determining an active session time by excluding the duration of the repetitive activity from a total session time.

7. A computer-implemented method for analyzing Internet usage, the method comprising:

receiving proxy log data, wherein the proxy log data include timing information of a plurality of Internet events;

determining a series of interval times associated with the plurality of Internet events;

calculating a series of single standard deviations representing a running standard deviation of the series of interval times;

calculating a double standard deviation of the series of single standard deviations; and

detecting an automated activity if the double standard deviation is below a first pre-determined standard deviation threshold for a time period longer than a time threshold.

8. The method of claim 7, further including detecting an automated activity if the single standard deviation is below a second pre-determined standard deviation threshold for a time period longer than the time threshold.

9. The method of claim 7, wherein determining a series of interval times includes:

sorting the proxy log data in a chronological order; and

determining each interval time as the temporal distance between every two consecutive proxy log data.

10. The method of claim 7, wherein the automated activity is an automated webpage refresh.

11. The method of claim 7, wherein the automated activity is an automated webpage pop-out.

12. The method of claim 7, further including indicating the detected automated activity to a user via a display interface.

13. The method of claim 12, further including:

receiving an input from the user, wherein the input includes a permission to remove the automated activity; and

removing proxy log data that correspond to the automated activity from the proxy log.

14. The method of claim 7, further including determining an active Internet usage time by excluding the duration of the automated activity from a total Internet usage time.

15. An Internet usage analyzer, comprising:

a network interface configured to receive proxy log data from a proxy server, proxy log data include timing information of a plurality of Internet events; and

a processor coupled to the network interface and configured to;

determine a series of interval times associated with the plurality of Internet events;

calculate a series of single standard deviations representing a running standard deviation of the series of interval times;

calculate a double standard deviation of the series of single standard deviations; and

detect an automated activity if the double standard deviation is below a first pre-determined standard deviation threshold for a time period longer than a time threshold.

16. The Internet usage analyzer of claim 15, wherein the processor is further configured to detect an automated activity if the single standard deviation is below a second pre-determined standard deviation threshold for a time period longer than the time threshold.

17. The Internet usage analyzer of claim 15, wherein the processor being configured to determine a series of interval times includes the processor being configured to:

sort the proxy log data in a chronological order; and

determine each interval time as the temporal distance between every two consecutive proxy log data.

18. The Internet usage analyzer of claim 15, further including a display interface configured to indicate the detected automated activity to a user of the Internet usage analyzer.

19. The Internet usage analyzer of claim 18, further including an input and output interface configured to receive an input from the user, wherein the input includes a permission to remove the automated activity;

and the processor is further configured to remove proxy log data that correspond to the automated activity from the proxy log.
