Volunteered geographic information (VGI) has entered a phase where there are both a substantial amount of crowdsourced information available and a big interest in using it by organizations. But the issue of deciding the quality of VGI without resorting to a comparison with authoritative data remains an open challenge. This article first formulates the problem of quality assessment of VGI data. Then presents a model to measure trustworthiness of information and reputation of contributors by analyzing geometric, qualitative, and semantic aspects of edits over time. An implementation of the model is running on a small data-set for a preliminary empirical validation. The results indicate that the computed trustworthiness provides a valid approximation of VGI quality. ARTICLE HISTORY
Outlining the general characteristics of embedded systems is an arduous task. In fact, the design of such kind of systems is heavily influenced by functional and non-functional requirements, and it is based on quite complex design flows. So, there is often the need to adopt a HW/SW co-design methodology able to support the designers during high-level phases so that they can perform early analysis before dealing with low-level ones. Such a methodology, to be effective, should consider also performance estimation and ESL HW/SW timing co-simulation. The goal of this paper is to introduce a novel and fast performance metric able to speed-up the early analysis and design space exploration to identify the more promising architectures for different application domains. In particular, the paper presents a framework to evaluate such a metric and to perform some preliminary analysis to evaluate its meaningfulness when exploited in the HW/SW domain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
