Dataset 1: 150*100 Web services QoS dataset.

We monitor 100 Web services by using 150 distributed computer nodes located all over the world.

  1. The dataset contains 150 files, where each file includes 10,000 Web service invocations on 100 Web services by a service user.
  2. Planet-lab is employed for monitoring the Web services.
  3. There are totally more than 1.5 millons Web service invocations.
  4. Each line in the file is a Web service invocation result, where the following table provides some samples of the results.

Dataset 2: 339 * 5825 Web service QoS dataset

Real-world QoS evaluation results from 339 users on 5,825 Web services.

This dataset includes:

  1. readme.txt (1 KB): descriptions of the dataset.
  2. userlist.txt (19KB): information of 339 service users. Format: | User ID | IP address of user | country | longitude | latitude |
  3. wslist.txt (505KB): information of the 5825 Web services. Format: | WS ID | WSDL address | provider name | country name |
  4. rtmatrix.txt (11MB) 339 * 5825 user-item matrix of response-time. Use ULtraEdit to open the file, since the file size is too large for Notepad.
  5. tpmatrix.txt (12MB): 339 * 5825 user-item matrix for throughput. Use ULtraEdit to open the file, since the file size is too large for Notepad.

Dataset 3: 142 * 4532 * 64 time-aware Web service QoS dataset

Real-world QoS evaluation results from 142 users on 4,532 Web services on 64 different time slots.

This dataset includes:

  1. readme.txt (1 KB): descriptions of the dataset.
  2. rtRate(480 MB): response-time values of 4,532 Web services when invoked by 142 service users in 64 time intervals. The data format is as following:
    | Time Interval ID | Web Service ID | Service User ID | Response-Time (s) |
    e.g.: 98 4352 33 0.311
  3. tpRate (571 MB): throughput values of 4,532 Web services when invoked by 142 service users in 64 time intervals. The data format is as following:
    | Time Interval ID | Web Service ID | Service User ID | Throughput (kbps) |
    e.g.: 91 1196 62 32.882355
