Ensemble learning aims at combining several slightly different learners to construct stronger learner. Ensemble of a well selected subset of learners would outperform than ensemble of all. However, the well studied accuracy / diversity ensemble pruning framework would lead to over fit of training data, which results a target learner of relatively low generalization ability. We propose to ensemb...

Abstract A new methodology/data structure, the clause tree, is developed for automated reasoning based on resolution in first order logic. A clause tree T on a set S of clauses is a 4-tuple , where N is a set of nodes, divided into clause nodes and atom nodes, E is a set of edges, each of which joins a clause node to an atom node, L is a labeling of N ∪ E which assigns to each clause n...

This paper presents a technique to generate distractors for cloze questions in the context of a Computer-Assisted Language Learning tutoring system. The document will focus on an evaluation process used to measure the quality of the distractors that were automatically generated. The main goal of the present study is to be able to include this feature in the tutoring system.

OBJECTIVE To explore the way the doctor-patient communication process may be improved by adopting the patients' conversational style in the development of written materials for surgical patients. METHODS Written information prepared by doctors, specialists in abdominal surgery, was tested for comprehension on patients undergoing cholecystectomy, using the standard Cloze test procedure. At the...

To exploit the technological capabilities, adaptive distance learning sy...

By generalizing the notion of location of a constituent to allow discontinuous Ioctaions, one can describe the discontinuous constituents of non-configurational languages. These discontinuous constituents can be described by a variant of definite clause grammars, and these grammars can be used in conjunction with a proof procedure to create a parser for non-configurational languages.
