The cited papers which use the dataset list bellow:

 

  1. RegionKNN: A Scalable Hybrid Collaborative Filtering Algorithm for Personalized Web Service Recommendation
    We adopt the WSRec [5] dataset, which contains about 1.5 million web service invocation records of 100 web services from more than 20 countries. RTT records are collected by 150 computer nodes from Planet-Lab, which are distributed in more than 20 countries. We extract a subset of 300,000 RTT records, which ranges from 2 to 31407 milliseconds. 3000 users are generated, each of whom is associated with a RTT profile of all the 100 services.

  2. An Effective Web Service Recommendation Method based on Personalized Collaborative Filtering
    We adopt a dataset provided by ZiBin Zheng [17] for our experiments. The dataset contains 150 files, where each file includes 10,000 Web service invocations on 100 Web services by a service user. There are totally more than 1.5 millions Web service invocations. Each line in the file is a Web service invocation result, where the Table IV provides several samples of the results. In this table, the ClientIP denotes different users, WSID represents different service items. The other four items are QoS attributes.

  3. Location-Aware Collaborative Filtering for QoS-Based Service Recommendation
    In our experiments, we adopt a real-world Web service dataset: WSDream dataset 25 , which was published in references [12,13]. The dataset contains QoS records of service invocations on 5825 Web services from 339 service users, which are transformed into a user-service matrix. Each item of the user-service matrix is a pair of values: Round-Trip Time (RTT) and throughput (TP). Therefore the original user-service matrix can be decomposed into two simpler matrices: RTT matrix and TP matrix. We use either RTT matrix or TP matrix to compute user similarity and service similarity in the experiments.

  4. Collaborative Web Service QoS Prediction with Location-Based Regularization
    We have conducted our experiments on a public real world Web service QoS dataset, which is collected by Zibin Zheng et.al. It contains 1,974,675 Web service response time records. These results are collected from 339 distributed service users on 5,825 Web services. Each user record contains geographical information. More details about this dataset can be found in [7].

  5. An Extended Matrix Factorization Approach for QoS Prediction in Service Selection

These results are collected from 339 distributed service users on 5,825 Web services. More details about this dataset can be found in [9].

  6. Recommending Web Services via Combining Collaborative Filtering with Content-based Features
    Luckily, there is a recent effort made by Zheng et al. [5] in their WS-DREAM project6, which shares a large-scale real Web service dataset. WS-DREAM developed a Web crawling engine to crawl publicly available WSDL file addresses from the Internet. It also collected non- functional attributes (e.g., QoS) of these Web services, which are observed by 339 distributed computers located in 30 different countries, from Planet-Lab7. We use this dataset as our base dataset and perform the following pre-processing

  7. Hybrid Collaborative Filtering algorithm
 for bidirectional Web service recommendation
    Our experiments employ the real-world Web service QoS data set.1 The dataset includes 100 publicly available Web services hosted by more than 20 providers and 150 distributed computers from Planet-Lab [7,34]. The service consumers (distributed computer from Planet-Lab) observe and collect QoS attributes of Web services. By processing the open source files, we construct a 150 × 100 × 20 consumer-service-provider cube.

  8. Web Service QoS Prediction based on Multi Agents
    In this simulation we have used the WS-DREAM dataset represented by Zibin Zheng and Michael R. Lyu in [18] which is offers real world web service invocation data. The data given for web service response time (ms) was used in order to simulate our QoS prediction mechanism.

  9. Decision Tree Learning from Incomplete QoS to Bootstrap Service Recommendation
    The experiments are conduced on a real world QoS dataset that consists of 1.5 million service invocation records. 150 computer nodes from the Planet-Lab2, which are located in over twenty countries, are leveraged to automatically invoke a hundred selected Web services. These services are distributed across more than twenty countries. Each computer node invokes each service for 100 times and the average Round-Trip Time (RTT) is used as the QoS dataset in our experiments.

  10. Personalized Context-Aware QoS Prediction for Web Services Based on Collaborative Filtering
    In the experiment we use the dataset from the WSRec including a user-contribution mechanism for Web Service QoS information collection, which is implemented by java language and deployed to the real-world environment [5, 14]. This dataset includes 100 Web Services and 150 computer nodes (users) which are distributed in 22 countries. We obtain a 150×100 user-service item matrix from this database, where each entry in the matrix represents the QoS value (RTT).

  11. QoS Driven Web Services Evolution
    In our experimental scenario we use dataset from the WSRec including a user-contribution mechanism for web service QoS information collection, which is implemented by java language and deployed to the real-world environment [8, 9]. This dataset includes 100 web services and 150 computer nodes (users) which are distributed in 22 countries. We obtain a 150×100 user-service item matrix from this database, where each entry in the matrix represents the QoS values (e.g., RTT, Failure-rate).

  12. Trust-Based Personalized Service Recommendation: A Network Perspective
    In this study, we use a real world dataset from WS-DREAM1[39]. The characteristics of the dataset are described in Table 1. 100 users invoked 2 000 real world services from public sources on the Web. Each user invoked each service 30 times. The behaviors of services in each interaction, as well as the observed QoS performance (response time and throughput) were recorded.

  13. WSRank: A Collaborative Ranking Approach for Web Service Selection
    We adopt the WSRec [7] dataset, which contains about 1.5 million web service invocation records of 100 web services from more than 20 countries. We extract a subset of 300,000 QoS records and 3000 users are generated, each of whom is associated with a QoS profile of all the 100 services. As for our QoS model, we take two QoS properties, RTT and throughput with equal weight as an example.

  14. QoS-aware service selection via collaborative QoS evaluation
    We use the real-world QoS dataset created by WSRec [40]. In WSRec, a list of 21,197 publicly available Web services are obtained by crawling leading service provider websites, portal websites that publish publicly available Web services, and service search engines. The actual working services are less due to authentication restriction, permanent invocation failure, or extremely long processing duration. One hundred Web services are randomly selected from the working services.

  15. Multi-user web service selection based on multi-QoS prediction
    To study the prediction performance on multi-QoS, we con- duct several experiments to show the prediction quality of our proposed approach on real-world Web service dataset (Zheng et al. 2010). This dataset includes QoS performance of 5,825 openly-accessible real-world Web services from 73 countries. The QoS values are observed by 339 distributed computers located in 30 countries from PlanetLab4. The detail can be describe as Table 1.

  36. Diversifying Web Service Recommendation Results via Exploring Service Usage History
    To obtain solid experimental results, it is ideal to use a real world Web service dataset. Zheng et al. [29] pub- lished a large-scale real world Web service dataset ac- quired in their WS-DREAM project1. WS-DREAM is a Web service crawling engine that collects publicly availa- ble WSDL file addresses from the Internet. It also col- lected QoS information of these Web services by using 339 distributed computers to monitor the Web services. This dataset has been widely used for performance evalu- ation by previous work on Web service recommendation.

  49. A Game Theory-based Approach to Service Rating
    As there are no real-world data available for evaluating a rating system in the presence of manipulators, simulations were used to compare the rating prediction accuracy of the proposed scheme (GTS) with the schemes by Zheng et al.[15] (WSRec), Malik et al. [7] (RATEWeb), and Zhang et al. [14] (Personalised).

  50. A Highly Accurate Prediction Algorithm for Unknown Web Service QoS Values

We implemented the experiments employing JDK 7.0 and eclipse 4.3 on Windows Server 2008 R2 Enterprises with Inter Xeon E5-2670 eight-core 2.60 GHz CPU and 32G RAM. Our experiments mainly consists of two parts: 1) Section 3.3 compares our algorithm with other 7 well known prediction methods based on the throughput as well as response time dataset; 2) Section 3.4 and 3.5 study the optimal parameters user_topK and item_topK of our algorithm.

  51. A location-aware hybrid web service QoS prediction algorithm
    In this section, we verify the performance of HUWAA through experiments. The dataset, collected by Zheng et al. [12], contains 1 974 675 recorded response times of users invoking online services. More specifically, the dataset contains the response times and throughput records of 339 users and 5 825 Web services. For our experiments, we randomly sampled 150 users and Web services.

    Some experiments were carried out to evaluate the prediction accuracy and the robustness of the proposed scheme. In the experiments, all the attributes of a service are given equal weight in formula (1). In L is set to 3. The first experiment compares the prediction accuracy of the proposed scheme with the scheme by Zheng et al.[25] which is one of the best service recommendation schemes. The comparison used the data set collected by Zheng [24] and Zhang [23] (http://www.wsdream.net).

  53. Cloud Service Recommendation based on Trust Measurement Using Ternary Interval Numbers
    We used the WS-DREAM datasets [15], and supplemented some real data about user feature, including AS number, city, network description or area, and so on. And the detailed raw data used by our experiments are provided online [16]. Then a three-level location code, consisting of country, city and area, can be generated. The datasets provides response time matrix of service invocations. Comparing the response time provided by consumers with user expectation value, the trust degree of QoS is calculated as follows.

    Zibin’s dataset [19],[20] is popularly used in a number of papers [14],[17], this is a real-world dataset which only consists of two types of QoS but not WSDL files. In order to discover the topic information of Web services, we crawl the corresponding WSDL files whose URLs (Uniform Resource Locator) have been given in Zibin’s dataset from Internet. In this paper, our dataset primarily consists of the users- Web services responding time QoS matrix and WSDL files of corresponding services. There are 339 users and 2344 Web services in our dataset.

Each item of the user-service matrix is a pair of values: response-time and throughput.

  57. Combining QoS prediction and customer satisfaction estimation to solve cloud service trustworthiness evaluation problems
    To ensure the typicality and objectivity of QoS prediction, an open QoS research dataset [37] will be employed to predict the assessment data on Performance and Availability. These QoS data (response-time and throughput) were collected from 339 users on 5825 web services in a real-world environment. Since it is impractical to discover and distinguish all functionally-equivalent cloud services at the selection time, we randomly select 100 web services’ QoS reports for our experiment.

Each user is described by UserID, IP address of user, country, longitude, latitude. Each service is described by WSID, WSDL address, provider name, country name.

  62. Online Optimization of Collaborative Web Service QoS Prediction Based on Approximate Dynamic Programming
    To test the performance of our approach in real-world, we use a common data set collected from 339 service users on 5, 825 web services [9]. This experiment focuses on the investigation for the response time of different web services and service users. Response time is one of the representative QoS values, which is defined as the time duration between sending a request and receiving a corresponding response for a service user.

  63. Performance Evaluation of Web-Services Classification
    A mechanism for past Web service QoS information collection using different service users was proposed by Zheng et al.12. Based on collected QoS data, a collaborative filtering approach predicted Web service QoS values. In the end, a prototype called WSRec was implemented through Java language and deployed in the Internet to conduct real-world experiments.

The original data set contains 5825 service invocation records from 339 users, and QoS attributes include response time (RT) and throughput (TP).

  66. Search-based QoS ranking prediction for web services in cloud environments
    To validate the effectiveness of our search-based QoS ranking algorithm, we performed experiments on some publicly available Web services QoS data1 which had been collected by Zheng et al. [18,10]. The data set includes 500 eal-world Web services with 300 distributed computers (users) on the Planet-Lab2 platform, and so the Web QoS values were gathered by monitoring service invocation from the distributed computers (users).

    depicts the compiled priority scheduled data. This paper, collected data used in WSP approach [11] a QoS dataset for experiment, comprising the response times between 200 users (PlanetLab nodes) and 1,597 Web services, together with the network distances between the 200 distributed nodes, for our SPW approach. And response time is calculated using QOS based algorithm[11].

  68. Time Aware and Data Sparsity Tolerant Web Service Recommendation Based on Improved Collaborative Filtering
    We use a freely available dataset provided by Zhang et al. [33] for experiments. They employed 142 distributed computers from Planet-Lab1 to evaluate the response time and throughput of 4532 Web services during 64 continuous time intervals, with each time interval lasting for 15 minutes. Accordingly, the dataset contains 64 matrices for response time and 64 matrices for throughput, and each matrix has 142 rows and 4532 columns.

  69. Topic Model based Collaborative QoS Prediction
    Zibin’s dataset [22],[23] is popularly used in a number of papers [15],[20], this is a real-world dataset which only consists of two types of QoS but not WSDL files. In order to discover the topic information of Web services, we crawl the corresponding WSDL files whose URLs (Uniform Resource Locator) have been given in Zibin’s dataset from Internet. In this paper, our datasets primarily consist of the users-Web services responding time QoS matrix and WSDL files of corresponding services.

  70. Towards QoS Prediction for Web Services based on Adjusted Euclidean Distances
    We have conducted our experiments using a public realworldWeb service QoS dataset, which is collected by Zibin Zheng et.al [9]. It contains the records of 1, 974, 675 Web service invocations executed by 339 distributed service users on 5825 Web services. The record of each invocation contains 2 parameters: Response Time and Throughput. More details about this dataset can be found in [6]. In this paper, we randomly extract 150 users, 100 Web services and use the invocation records between them as the experimental data.

  71. Unified Collaborative and Content-Based Web Service Recommendation
    To perform reliable experiments, it is ideal to use large-scale real world web services. Unfortunately, collecting and preparing such data is extremely time-consuming. Fortunately, Zheng et al. [8] shared a large-scale real world web services dataset collected in their WS-DREAM project. WS-DREAM is a web crawling engine that crawled publicly available WSDL file addresses from the Internet.

  72. Web Service Composition Optimization Based on Improved Artificial Bee Colony Algorithm
    In Web service QoS modeling research, Zhang et el. [1] presents a novel hybrid data type (including real numbers, interval numbers, triangular fuzzy numbers and intuitionistic fuzzy numbers) QoS model, and presented a dynamic composition algorithm based on TOPSIS (DWSCA_TOPSIS) is to evaluate multi-period hybrid QoS data. An intuitionistic fuzzy set-based QoS model was presented in Ref. [6]. A QoS model based on random numbers was resented in Ref. [8].

  73. Web Service QoS Prediction under Sparse Data via Local Link Prediction
    The dataset contains response time and throughput records of 339 users and 5825 Web services. And we randomly sample the users-Web services matrix for constructing the sparse data. We just use the spare data for predicting the response time.

  74. Web Service Recommendation using Optimized Iterative Collaborative Filtering
    In our experiments, a series of programs implemented with Matlab are running on a PC with Intel Xeon X7460 CPU and 64G RAM. Additionally, the data set we used in this paper is from WS-DREAM[18,22].19 Two features of the QoS value collected in the data set are response-time and throughput, both of which contain a user-item matrix(339*5825). To evaluate the prediction accuracy and performance of different models, 10 user-item matrices(150*200) without missing value are selected from the original data set to serve as the real world QoS data.

  75. Investigating QoS of Real-World Web Services
    To attack this critical challenge, we make a great effort to conduct three large-scale distributed evaluations on real-world web services, collect comprehensive web service QoS data sets, and publicly release these reusable data sets for future research. First, 21,358 web service addresses are obtained by crawling web service information from the Internet. Then three web service evaluations are conducted. In the first evaluation, failure probability of 100 web services is assessed by 150 distributed service users. In the second evaluation, response time and throughput of 5,825 web services are evaluated by 339 distributed service users.

  76. A Framework for Similarity Search of Web Services
    The experiments were conducted over four datasets which were synthetically generated from the two publicly accessible WS data colletions4,5 The WS data in these collections are gathered from real world service sites.

  77. A Framework for Automated Service Negotiation
    WSDream-QoSDataset [46] is used, which contains more than 150 Web services distributed in computer nodes located all over the world (i.e., distributed in 22 different countries). Planet-Lab is employed for monitoring the Web services. We take the published services and their corresponding QoS values and write our own wrappers that incorporate the NegFs negotiation component.

  78. Binary PSO for Web Service Location-Allocation
    The datasets used for the experiments were generated from the WS-DREAM dataset [27]. The WS-DREAM dataset is a collection of historical data from 339 users and 5824 web services located in different locations. It records several non-functional attributes about the web services, including response time, IX throughput, availability, etc.

  79. A Web Service Discovery Method Based on Data Segmentation and WordNet
    Data used in this paper are from Dr. Yilei Zhang’s research results [13], including 3,738 WSDL files [14]. We use the JAVA language to extract Web service features in addition to using WSDL4J and Princeton WordNet

  80. Automated Negotiation Using Semantic Rules
    WSDream-QoSDataset [28] is used, which contains more than 150 Web services distributed in computer nodes located all over the world (i.e., distributed in 22 different countries). Planet-Lab is employed for monitoring the Web services. We take the published services and their corresponding QoS values and write our own wrappers that incorporate the NegF's negotiation component.

  81. Reducing search space for Web Service ranking using semantic logs and Semantic FP-Tree based association rule mining
    However, such datasets are not publically available. We used and adapted a dataset from [22] and www.webservicelist.com which provides different parameters including functional and non-functional properties of Web Services.

  82. Exploring QoS of Genuine Web Administrations
    In the first assessment, disappointment likelihood of 100 web administrations is surveyed by 150 appropriated administration clients. In the second assessment, reaction time and throughput of 5,825 web administrations are assessed by 339 appropriated administration clients. Also in the third assessment, QoS changing of 4,532 web administrations with time is mulled over by directing 30,287,611 web administration summons by 142 clients in 64 time openings with a period interim of 15 minutes.

  83. Multidimensional Analysis of Heterogeneous Relationships in Internet of Things
    However, Zheng et al.[156] shared a large-scale real world data in their WS-DREAM project. WS-DREAM is a crawling engine that crawled publicly available WSDL life addresses from the Internet. It also collected non-functional attributes (e.g. QoS) of these services, which are observed by 339 distributed computers located in 30 different countries, from Planet-Lab4. In our experiments, we used this dataset as our base dataset and performed some pre-processing activities.

  84. AN ADAPTIVE SYSTEM FOR WEB SERVICES THROUGHPUT PREDICTION
    To train the adaptive model I use the Web service QoS dataset built by [3] They collected a 339 * 5825 user-item matrix for throughput, where an entry Ra,i in the matrix is the throughput of Web service i observed by the service user a.

    So, we have taken the web services related dataset which was created by Zheng et al. [6]. The details about the dataset are given in table-I.

  86. Novel Optimal and Scalable Nonfunctional Service Matchmaking Techniques
    During the experiments, the experimental framework relies on generating the NFSSs either randomly or based on real measurements executed on real web services. For generating realistic NFSSs, the framework relies on the WS- Dream’s third QoS dataset [20] which was produced by measuring the performance of 4500 web services when invoked by 142 service users, distributed around the globe, in 64 time intervals.

  87. A Evaluation Method for Web Service with Large Numbers of Historical Records
    The employed experiment data is from web service QoS dataset WS-DREAM [9] published by Dr. Zibin Zheng in 2011. WS-DREAM consists of 4532 web services from public sources on the web, and 142 distributed computers from Planet-Lab are employed for evaluating the QoS performance of web services in 64 time intervals.

  88. User-credibility Based Service Reputation Management for Service Selection

This dataset includes the throughput and respond time of 5825 services which they are invoked by 339 users. Therefore, 339 throughputs and respond times are collected for each service.

  91. A Hierarchical Self-Healing SLA for Cloud Computing
    This study used the throughput and respond time dataset collected from Zheng [34, 35] which its validity is confirmed in his study [17, 35-37].

  92. Hybrid Genetic Algorithm for Optimal Service Redundancy Configuration in Service Composition
    To evaluate MSHGA, we have simulated 10 groups of reliability, performance and cost data for 12 services in it. These data are randomly chosen from two datasets: (1) the QWS Dataset [23] and (2) dataset collected by WS-DREAM [16].

  93. Ranking Web Services with Limited and Noisy Information
    In this paper, we adopt WSDream dataset, which includes response time and throughput QoS values of a number of web services in reality [24], [25]. The datasets are collected by executions of nearly 2 million real-world web service invocations from 339 service users in 30 different countries. 5,825 real-world web services from 73 countries are evaluated, and more than 3.9 million pieces of data are recorded.

  99. A Method of QoS Deviation Monitoring for Web Services
    Experiments were run in a Lenovo PC machine, configured as Intel Core i5-4200M 2.50 GHz CPU, RAM 4 GB. We choosed Matlab as our development environment and used the real data provided in QoS data sets [16-17] as the experimental QoS data.

  100. A Partial Selection Methodology for Efficient QoS-Aware Service Composition

  105. Optimization of Location Allocation of Web Services Using A Modified Non-dominated Sorting Genetic Algorithm
    To evaluate the effectiveness and efficiency of our proposed NSGA-II based approach to service location-allocation. We compare our approach with the GA-based single objective approach in Section 5 using an existing dataset, WS-DREAM [31] [32], which is a historical dataset on QoS of Web services from different locations. It contains the data of latencies from 339 different user locations invoked 5824 web services scattered over different locations.

  106. Preference and Honesty Aware Trust Model for Web Services

  115. Evaluating Web Service QoS: A Neural Fuzzy Approach

However, the dataset do not support much variety of quality parameters (i.e. availability is not considered).

The QoS values are observed by 339 distributed computers located in 30 countries from PlanetLab4. The detail can be describe as Table.I.

In some cases (e.g., requestFlightChoice and makePayments) we used real values taken from the experiments performed in [35]. Otherwise,we based these parameters on the statistics presented in [31], which were related to generic WSs, thus characterizing all the other WSs with the same value of .

WSDREAM contains 4 plain-text files, which are the users’ information, the services information, the response-time values of the service invoking and the throughput values of the service invoking. For simplicity, we only use the response-time as the reliable values to predict.

  130. Input Projection Algorithms Influence in Prediction and Optimization of QoS Accuracy
    In this study, in order to train the MLP, we made use of two large datasets: RTMATRIX and FPMATRIX. Each matrix has a size of 339 lines x 5825 columns. RTMATRIX consists of web services response time values while FPMATRIX stores similar web services throughput values. In our previous research works [1]- [5] we concluded that MLP-2-M and MLP-2-CG offered the most accurate prediction results for RTMATRIX and FPMATRIX, respectively. FPMATRIX and RTMATRIX were built by Z. Zheng, Y. Zhang and M.R. Lyu in [20] and [21].
