An Overview of Blockchain Technology: Architecture, Consensus, and Future Trends
TLDR
An overview of blockchain architechture is provided and some typical consensus algorithms used in different blockchains are compared and possible future trends for blockchain are laid out. Expand
Blockchain challenges and opportunities: a survey
TLDR
The blockchain taxonomy is given, the typical blockchain consensus algorithms are introduced, typical blockchain applications are reviewed, and the future directions in the blockchain technology are pointed out. Expand
QoS-Aware Web Service Recommendation by Collaborative Filtering
TLDR
This paper proposes a collaborative filtering approach for predicting QoS values of Web services and making Web service recommendation by taking advantages of past usage experiences of service users, and shows that the algorithm achieves better prediction accuracy than other approaches. Expand
WSRec: A Collaborative Filtering Based Web Service Recommender System
TLDR
The comprehensive experimental analysis shows that WSRec achieves better prediction accuracy than other approaches, and includes a user-contribution mechanism for Web service QoS information collection and an effective and novel hybrid collaborative filtering algorithm for Web Service QoS value prediction. Expand
Collaborative Web Service QoS Prediction via Neighborhood Integrated Matrix Factorization
TLDR
This paper proposes a collaborative quality-of-service (QoS) prediction approach for web services by taking advantages of the past web service usage experiences of service users, and achieves higher prediction accuracy than other approaches. Expand
Drain: An Online Log Parsing Approach with Fixed Depth Tree
TLDR
This work proposes an online log parsing method, namely Drain, that can parse logs in a streaming and timely manner, and uses a fixed depth parse tree, which encodes specially designed rules for parsing. Expand
Collaborative reliability prediction of service-oriented systems
TLDR
A collaborative reliability prediction approach, which employs the past failure data of other similar users to predict the Web service reliability for the current user, without requiring real-world Web service invocations, is proposed. Expand
Learning Semantic Representations for Unsupervised Domain Adaptation
TLDR
Moving semantic transfer network is presented, which learn semantic representations for unlabeled target samples by aligning labeled source centroid and pseudo-labeled target centroid, resulting in an improved target classification accuracy. Expand
Investigating QoS of Real-World Web Services
TLDR
This work investigates QoS of real-world web services and provides reusable research data sets for validating various QoS-based techniques and models and releases comprehensive web service QoS data sets publicly released online. Expand
Tools and Benchmarks for Automated Log Parsing
TLDR
This paper presents a comprehensive evaluation study on automated log parsing, evaluating 13 log parsers on a total of 16 log datasets spanning distributed systems, supercomputers, operating systems, mobile systems, server applications, and standalone software and reports the results in terms of accuracy, robustness, and efficiency.
