Human-Machine Conversations to Support Coalition Missions with QoI Trade-Offs
نویسندگان
چکیده
Supporting coalition missions by means of networked information resources in a dynamic environment presents challenging problems, not least in terms of human-machine collaboration. Human users need to task the network to help them achieve mission objectives, while humans are also sources of mission-critical information. Information quality is highly variable, both due to the nature of the sources and the network capacity. We propose a natural language-based conversational approach to supporting human-machine working in a coalition mission context. We present a model for human-machine and machine-machine interactions in a realistic mission context, and evaluate the model using an existing surveillance mission scenario. The model supports the flow of conversations from full natural language to a form of Controlled English (CE) amenable to machine processing and automated reasoning, including highlevel information fusion tasks and QoI trade-offs, and the enforcement of policies for security and resource management. We introduce a mechanism for presenting the gist of verbose CE expressions in a more convenient form for human users, and show how the conversational interactions supported by the model include requests for expansions and explanations. We discuss how these mechanisms can support QoI trade-offs and enforcement of security and management policies.

Ethical Perspective: Five Unacceptable Trade-offs on the Path to Universal Health Coverage
This article discusses what ethicists have called “unacceptable trade-offs” in health policy choices related to universal health coverage (UHC). Since the fiscal space is constrained, trade-offs need to be made. But some trade-offs are unacceptable on the path to universal coverage. Unacceptable choices include, among other examples from low-income countries, to expand coverage for services wit...
متن کاملA New Approach to Architecture of Sensor Networks for Mission-Oriented Applications
In this paper, a novel mission-oriented sensor network architecture for military applications is proposed involving multiple sensing missions with varying quality of information (QoI) requirements. A new concept of mission QoI satisfaction index indicating the degree of satisfaction for any mission in the network is introduced. Furthermore, the 5WH (why, when, where, what, who, how) principle o...

The World Health Organization’s (WHO’s) World Health Report 2010, “Health systems financing, the path to universal coverage,” promoted universal health coverage (UHC) as an aspirational objective for country health systems. Yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the conside...
