PrePrint: Key Challenges in Cloud Computing to Enable the Future Internet of Services

admin — Sat, 19 May 2012 15:14:15 +0000

Cloud computing will play a major role in the development of the future Internet of Services, enabling on-demand provisioning of applications, platforms, and computing infrastructures. However, there are several technology challenges that must be addressed to turn this vision into reality. Specific challenges in the deployment of future IaaS clouds include the efficient management of infrastructure clouds to deliver scalable and elastic service platforms on-demand, the development of cloud aggregation architectures and technologies to enable the collaboration and interoperation of cloud providers, and improvements in security, reliability and energy efficiency of cloud infrastructures.

PrePrint: A framework to analyze crowd labor and design a proper set of incentives for humans in the loop

admin — Fri, 11 May 2012 17:31:34 +0000

In the last few years, a growing number of companies has taken advantage of crowdsourcing techniques in order to solve problems outside the reach of pure automatic computation. In this context, participation and willingness to contribute become two of the critical issues that both organizations and software designers need to take into account for developing effective solutions. Many studies have focused on motivations and incentives, but they mainly analyze specific crowdsourcing initiatives, or groups of contributors.

PrePrint: An experiment in comparing human-computation techniques

Master — Fri, 11 May 2012 17:31:33 +0000

We compare two human-computation techniques, games-with-a-purpose and microtask crowdsourcing with respect to their costs and benefits for the resolution of semantic-technologies related tasks, such as knowledge representation, ontology alignment and semantic annotation. We present a theoretical analysis of the trade-offs of the two techniques and an experiment in which entities and classes thereof described in the English Wikipedia are used to build a large general-purpose ontology. In the experiment we replicated the problem-solving setting of the OntoPronto game via Mechnical Turk, using a similar task design structure, evaluation mechanisms, and input data.

PrePrint: WebSocket for Communication and Display of Real-Time Data

Master — Fri, 04 May 2012 17:28:22 +0000

This paper investigates the use of the WebSocket protocol and implementation as an improvement on the latency of the HTTP polling technique for low volume real-time data communication on the internet. To test the hypothesis that WebSocket communication is faster than HTTP polling, we built a web application to measure the one-way transmission latency (from server to client) of sending real-time wind sensor data at a rate of 4 Hz. For WebSocket protocol testing, we implemented a Jetty servlet to upgrade an HTTP connection to a WebSocket connection.
