Supporting policy-driven behaviors in web services

Nirmal K. Mukhi, Pierluigi Plebani
2004 Proceedings of the 2nd international conference on Service oriented computing - ICSOC '04  
The Web services platform is gaining popularity as the technology of choice for integrating applications in diverse and heterogeneous distributed environments, such as the Internet. It is widely recognized that one of the barriers preventing widespread adoption of this technology is a lack of products that support non-functional features of applications, such as security, transactionality and reliability. Supporting such features in a service-oriented environment is more complex than
more » ... distributed computing environments since such behaviors cannot be assumed by applications, but some persistent representation of the behavior has to be discovered dynamically. WS-Policy has been touted as a possible future standard way to specify these features and associate them with services, but the multitude of related proposals resemble a poorly manufactured jigsaw puzzle more than a coherent vision. This paper clarifies this vision by presenting a working prototype that demonstrates how the quality features can be expressed as service policies using WS-Policy. These policies are enforced by a policy framework that allows dynamic association of such non-functional features with applications on a per-interaction basis, as well as modification of these features. The paper discusses the issues involved in the creation of such a policy framework, and how the requirements of having to support transactional and reliable services guided the design. We hope that this work encourages other efforts to create viable products based on these emerging standards and advances the science of Service Oriented Computing.

Cooperative middleware specialization for service oriented architectures

Nirmal K. Mukhi, Ravi Konuru, Francisco Curbera
2004 Proceedings of the 13th international World Wide Web conference on Alternate track papers & posters - WWW Alt. '04  
Service-oriented architectures (SOA) will provide the basis of the next generation of distributed software systems, and have already gained enormous traction in the industry through an XML-based instantiation, Web services. A central aspect of SOAs is the looser coupling between applications (services) that is achieved when services publish their functional and non-functional behavioral characteristics in a standardized, machine readable format. In this paper we argue that in the basic SOA

We propose specific extensions to the SOA model to allow service providers and requestors to dynamically expose and negotiate their public behavior, resulting in the ability to specialize and optimize the middleware supporting an interaction. We introduce a middleware architecture supporting this extended SOA functionality, and describe a conformant implementation based on standard Web services middleware. Finally, we demonstrate the advantages of this approach with a detailed real world scenario.

Business Provenance – A Technology to Increase Traceability of End-to-End Operations [chapter]

Francisco Curbera, Yurdaer Doganata, Axel Martens, Nirmal K. Mukhi, Aleksander Slominski
2008 Lecture Notes in Computer Science  
Today's enterprise applications span multiple systems and organizations, integrating legacy and newly developed software components to deliver value to business operations. Often business processes rely on human activities that may not be predicted in advance, and information exchange is heavily based on e-mails or attachments where the content is unstructured and needs discovery. Visibility of such end-to-end operations is required to manage compliance and business performance. Hence, it

Our business provenance solution provides a generic data model and middleware infrastructure to collect and correlate information about how data was produced, what resources were involved and which tasks were executed. Business provenance gives the flexibility to selectively capture information required to address a specific compliance or performance goal. Additionally, a powerful correlation mechanism yields a representation of the end-to-end operation that puts each business artifact into the right context, for example, to detect situations of compliance violations and find their root causes.

Research Questions to Support Conversational Learning in the Era of Ubiquitous, Mobile Agents

2018 International Conference of the Learning Sciences  
This poster explores the major question: How can conversational agents, such as smart speakers, be used for opportunistic learning that complements formal teaching? We discuss design questions that arise as devices are to be used for encouraging effective, brief conversational learning. We highlight aspects of efficacy in supporting learning through interdisciplinary study, and list research questions that need to be addressed. Ambient conversational devices as a new interaction modality for

This observation served as a motivation for several research efforts in utilizing Artificial Intelligence for Education, leading to the development of sophisticated tutoring systems for one-on-one human tutoring (VanLehn, 2011) . In this paper, we study the opportunities enabled by ubiquitous conversational agents, which can use some of the strategies employed by successful human teachers. These continuously available teaching agents, accessed at different times of the day or different places through various physical interfaces, can extend the functionality of existing intelligent tutoring systems by using multimodal signals uniquely provided by rapidly available mobile technology: location services, off-classroom time, bio-sensor data, and communication with cloud-enabled devices in the office, home, classroom, and vehicle. The number of people of all ages using conversational agents is growing (Lenhart, 2015; Druga, Breazeal, Williams, & Resnick, 2017) . Voice-based agent work builds on 50 years of technical exploration (Pieraccini, 2012) . While sophisticated agents that move beyond simple information retrieval are just over the horizon, these developments are currently driven by non-learning applications. As the number of learners who access and use conversational agents outside the formal education facility grows past a tipping point, learning sciences can guide interdisciplinary research agendas and enable learning to happen anytime and anywhere.
