Three National Science Foundation (NSF) programs—Human–Computer Interaction, Universal Access, and Digital Society and Technologies—were recently combined into one new cluster called “Human-Centered Computing” (HCC). Two workshops were held to share information about this new cluster with researchers, provide guidance to researchers who are early in their research careers and have yet to receive NSF funding, and provide feedback to NSF from the affected research communities regarding topics that are considered particularly important by this community. Continuing and emerging research opportunities identified included privacy and security issues in HCC context, intelligent user interfaces, universal access including research for different populations such as children and older adults, mobile and ubiquitous computing, and social computing, among others. Various issues concerning interdisciplinary research opportunities were also raised, including understanding the disciplines, promotion and tenure concerns, administrative overhead, and where to publish. Education discussions produced a list of curricular recommendations and a number of opportunities to enhance the education of future HCC practitioners and researchers. 相似文献

Service-oriented computing promotes the idea of assembling application components into a network of services that can be loosely coupled to create flexible, dynamic business processes and agile applications that span organizations and computing platforms. An SOC research road map provides a context for exploring ongoing research activities. 相似文献

From our previous work on biochemical applications, the structure of port graph (or multigraph with ports) and a rewriting calculus have proved to be well-suited formalisms for modeling interactions between proteins. Then port graphs have been proposed as a formal model for distributed resources and grid infrastructures, where each resource is modeled by a node with ports. The lack of global information and the autonomous and distributed behavior of components are modeled by a multiset of port graphs and rewrite rules which are applied locally, concurrently, and non-deterministically. Some computations take place wherever it is possible and in parallel, while others may be controlled by strategies. In this paper, we first introduce port graphs as graphs with multiple edges and loops, with nodes having explicit connection points, called ports, and edges attaching to ports of nodes. We then define an abstract biochemical calculus that instantiates to a rewrite calculus on these graphs. Rules and strategies are themselves port graphs, i.e. first-class objects of the calculus. As a consequence, they can be rewritten as well, and rules can create new rules, providing a way of modeling adaptive systems. This approach also provides a formal framework to reason about computations and to verify useful properties. We show how structural properties of a modeled system can be expressed as strategies and checked for satisfiability at each step of the computation. This provides a way to ensure invariant properties of a system. This work is a contribution to the formal specification and verification of adaptive systems and to theoretical foundations of autonomic computing. 相似文献

Reinforcement learning is a promising new approach for automatically developing effective policies for real-time self-management. RL can achieve superior performance to traditional methods, while requiring less built-in domain knowledge. Several case studies from real and simulated systems management applications demonstrate RL's promises and challenges. These studies show that standard online RL can learn effective policies in feasible training times. Moreover, a Hybrid RL approach can profit from any knowledge contained in an existing policy by training on the policy's observable behavior, without needing to interface directly to such knowledge 相似文献

The notion of "service" has spurred major evolutions for both information systems and the Web. A software application is no longer considered a monolithic component; it can be divided into services that are smaller components defined by their function and accessible through well-defined interfaces and protocols. As a result, IT actors are using service-oriented architectures (SOAs) to remodel the information systems of many companies while the Web is increasingly becoming a programmable place. In both domains, developers build composite client applications to consume these services. Even boundaries between enterprise services and Internet services are vanishing. Some companies, such as Strikelron provide enterprise services that were previously always hosted internally - like customer relationship management solutions. As a consequence, companies now have the technologies required to bring their business online. With Web services, private business processes can be exposed to partners through public composite Web applications. When new projects emerge, companies need guidance to properly handle such work. In this context, we aim to provide companies solutions - through a methodology, an architecture, and technical choices - that will help them solve generic problems such as security and application conception 相似文献
