Response time is one of the critical web service quality dimensions. It refers to how long it takes that a web service responds to request of a user. In order to manage the response time, pricing schemes can work as an efficient access control mechanism. In this paper, we study competition between two providers offering functionally same web services where there is a monopoly service provider...

Tying web services together to build large, distributed, collaborative applications has gathered noticeable momentum and a lot of research is being put in it. Along with composition of the web services, coordination is one key aspect that has been considered keenly. Many frameworks, languages and protocols have been proposed for web service composition and coordination. With the advancement in ...

SUMMARY SPrCY is a web-accessible database which provides comparison of structure prediction results for the Saccharomyces cerevisiae genome. This web service offers the ability to search, analyze and compare the yeast structural predictions from sequence-only (Superfamily, PDBAA BLAST and Pfam) and sequence-structure-based (SAM-T02, 3D-PSSM, mGenTHREADER) methods. AVAILABILITY The service is...

One of the current challenges in Mobile Computing is bringing services directly to mobile users, which is handicapped by two major hurdles: Phones and services do not interoperate as smoothly as they should and the delivered services have to be adapted to a wide range of different mobile client platforms. In order to address these problems we present a service framework that extends Semantic We...

One way of overcoming the challenges associated with mobile and pervasive computing environments involves providing users with higher levels of automation. This in turn requires capturing the context within which the user operates. In this paper, we describe ongoing research aimed leveraging Semantic Web Services in support of context awareness. This includes modeling sources of contextual info...

Adoption of mobile data services may be analyzed within the framework of two-sided markets. Service or content providers should adopt platforms for developing, integrating and distributing mobile services and end-users should adopt the offered services as well as the user platform offered. These two markets are often analyzed separately using different theoretical perspectives and models. In th...
