Article Type: Editorial From: International Journal of Web Information Systems, Volume 5, Issue 1

In its fifth year, the International Journal of Web Information Systems has grown stronger as a leading journal for publishing high quality papers from researchers, academics and practitioners of web information system and web technologies. In this first issue of volume 5, we present one survey paper and three regular papers.

The survey paper included in this issue is entitled “A survey on context-aware web service systems” contributed by Hong-Linh Truong and Schahram Dustdar from the Distributed Systems Group, Vienna University of Technology, Austria. The paper presents an extensive survey on the application of context-aware paradigm in web services. While much research has been conducted for context-aware in small scale, single-organizational applications, there is lack of work for the technique applied in multi-organizational applications through web-services. The survey compared existing context-aware web service-based systems based on techniques they support, as well as the application domains, system type, mobility support, multi-organizational support and level of web services implementation.

The second paper, “Towards an approach to sustain web services high-availability using communities of web services”, is a collaborative work from Zakaria Maamar (Zayed University, UAE), Quan Z. Sheng (The University of Adelaide, Australia), Samir Tata (Institut TELECOM, France), Djamal Benslimane (Claude Bernard Lyon 1 University, France) and Mohamed Sellami (Institut TELECOM, France). In this paper, the authors present the use of Communities of web services in case of replication failures of web services that require a high level of availability.

In the next paper, “Fast and efficient computation of reachability queries over linked XML documents graphs”, Awny Sayed from Minia University, Egypt proposes a methodology to create a scalable path index that can improve the performance of large queries in XML documents that contain links and cycles. The proposed technique is also proven to be superior to existing works in terms of ancestor-descendants relationship evaluation and for descendants-or-self queries on arbitrary graphs with link relationships.

The final paper in this issue, “Synthesizing correlated RSS news articles based on a fuzzy equivalence relation” by Maria Soledad Pera and Yiu-Kai Ng from Brigham Young University, USA proposes a novel clustering mechanism to filter RSS news articles by using the word-correlation factors in a fuzzy set information retrieval model. The clustering technique imposes small overheard cost and outperfoms other clustering techniques. While the proposal is applied to cluster RSS news articles, the technique can be used for many other application domains.

We extend an invitation to our previous and potential authors to submit their papers in the International Journal of Web Information Systems. We hope in 2009 we can engage more fruitful collaboration.
