We present an ecient hybrid method for aligning sentences with their translations in a parallel bilingual corpus. The new algorithm is composed of a length-based and anchor matching method that uses Named Entity recognition. This algorithm combines the speed of length-based models with the accuracy of anchor nding methods. The accuracy of nding cognates for(More)
Let (G, p) be an infinitesimally rigid d-dimensional bar-and-joint framework and let L be an equilibrium load on p. The load can be resolved by appropriate stresses w i,j , ij ∈ E(G), in the bars of the framework. Our goal is to identify the following parts (zones) of the framework: (i) when the location of an unloaded joint v is slightly perturbed, and the(More)
A huge amount of log data accumulates automatically during computer-based educational assessments that can be analyzed for diagnostic or educational purposes using data mining techniques. In this paper, we describe our work of mining students' complex problem solving interactions when tackling previously unknown and dynamically changing situations. Based on(More)
