Continuous Query for QoS-Aware Automatic Service Composition
Found in: 2012 IEEE 19th International Conference on Web Services (ICWS)
By Wei Jiang,Songlin Hu,Dongwon Lee,Shuai Gong,Zhiyong Liu
Issue Date:June 2012
pp. 50-57
Current QoS-aware automatic service composition queries over a network of Web services are often one-time innature. After a network of Web services is built, such queries are issued once, and answers are found from the scratch. The underlying assumption is...

Community Clustering for Distributed Publish/Subscribe Systems
Found in: 2012 IEEE International Conference on Cluster Computing (CLUSTER)
By Wei Li,Songlin Hu,Jintao Li,Hans-Arno Jacobsen
Issue Date:September 2012
pp. 81-89
Optimized placement of clients in a distributed publish/subscribe system is an important technique to improve overall system efficiency. Current methods, like interest clustering or publisher placement, treat a client as, either a pure publisher, or subscr...
 
Large-Scale Longitudinal Analysis of SOAP-Based and RESTful Web Services
Found in: 2012 IEEE 19th International Conference on Web Services (ICWS)
By Wei Jiang,Dongwon Lee,Songlin Hu
Issue Date:June 2012
pp. 218-225
While the usage of web services has increased explosively in recent years, very few studies examined the characteristics of web services using large-scale real data for a long period of time. In this paper, we present one such a large scale longitudinal an...
 
QSynth: A Tool for QoS-aware Automatic Service Composition
Found in: Web Services, IEEE International Conference on
By Wei Jiang, Charles Zhang, Zhenqiu Huang, Mingwen Chen, Songlin Hu, Zhiyong Liu
Issue Date:July 2010
pp. 42-49
With the proliferation of Web services, service engineers demand good automatic service composition algorithms that not only synthesize the correct work plans from thousands of services but also satisfy the quality requirements of the users. Our observatio...
 
Effective Pruning Algorithm for QoS-Aware Service Composition
Found in: E-Commerce Technology, IEEE International Conference on
By Zhenqiu Huang, Wei Jiang, Songlin Hu, Zhiyong Liu
Issue Date:July 2009
pp. 519-522
Abstract—Automatic service composition has been a hottopic in both academia and industry. It begins with syntacticcomposition, and then evolves semantic description. Recently, QoS of the composition comes into researchers’ mind, which aims at meeting the n...

This paper formalizes transactional properties for publish/subscribe client mobility and develops protocols to realize them.
 
ASCSS: An Automatic Service Composition Approach Based on Service Similarity
Found in: Semantics, Knowledge and Grid, International Conference on
By Wei Jiang, Songlin Hu, Wei Li, Wei Yan, Zhiyong Liu
Issue Date:December 2008
pp. 197-204
This paper realizes an approach for automatic service composition based on graph search (ASCGS for short). It forms an interoperable directed graph (IDG) by utilizing the interoperable relationships among services, and each request will be inserted tempora...
 
A Service Interoperability Assessment Model for Service Composition
Found in: Services Computing, IEEE International Conference on
By Jun Fang, Songlin Hu, Yanbo Han
Issue Date:September 2004
pp. 153-158
This paper presents an assessment model of service interoperability for service composition, which helps users to judge whether their composite services can be invoked properly. The model provides a clean and easy way to evaluate interoperability between a...

G-Finder: routing programming questions closer to the experts
Found in: Proceedings of the ACM international conference on Object oriented programming systems languages and applications (OOPSLA '10)
By Charles Zhang, Songlin Hu, Wei Li
Issue Date:October 2010
pp. 62-73
Programming forums are becoming the primary tools for programmers to find answers for their programming problems. Our empirical study of popular programming forums shows that the forum users experience long waiting period for answers and a small number of ...
