In this paper, an objective qtumtitative quality measure is proposed to evaluate tile performance of machiue translation systems. The proposed method is to compare the raw translation output of an MT system with the final revised version lor the customers, and then compute the editing efforts required to convert the raw translation to the final version. In contrast to the other prolx)sals, the ...

The inference of key infectious disease epidemiological parameters is critical for characterizing disease spread and devising prevention and containment measures. The recent emergence of surveillance records mined from big data such as health-related online queries and social media, as well as model inference methods, permits the development of new methodologies for more comprehensive estimatio...

This article falls under the problem of the symbolic monitoring of real-time complex systems or of video interpretation systems. Among the various techniques used for the on-line monitoring, we are interested here in the temporal scenario recognition. In order to reduce the complexity of the recognition and, consequently, to improve its performance, we explore two methods: the first one is the ...

This paper will describe a detailed analysis of a problem-based learning group to understand how an expert facilitator supports collaborative knowledge construction. The study examines the questions and statements that students and the facilitator generated as they traversed a complex conceptual space. The facilitator tended to use open-ended metacognitive questioning and never offered new idea...

CAPTCHAs are an important security tool for preventing automated attacks against online systems. However, they can be an undesirable source of friction in the user experience. In this poster, we propose a novel approach to dynamically improve the CAPTCHA experience for users by individually learning which types of CAPTCHA tests each user is best at solving and adapting future tests presented ba...

Visualisation is well known as an effective means of enriching user interaction with complex systems. Recent research with online communities has considered the application of visualisation tool support, with the intention of further improving communication between community members. This paper reviews existing work in this area with specific reference to the application of visualisation to imp...

The popularity of online information generally experiences a rising and falling evolution. This paper considers the "burst", "peak", and "fade" key events together as a representative summary of popularity evolution. We propose a novel prediction task-predicting when popularity undergoes these key events. It is of great importance to know when these three key events occur, because doing so help...
