The CoNLL-2014 shared task was devoted to grammatical error correction of all error types. In this paper, we give the task definition , present the data sets, and describe the evaluation metric and scorer used in the shared task. We also give an overview of the various approaches adopted by the participating teams, and present the evaluation results.(More)
We describe the NUS Corpus of Learner En-glish (NUCLE), a large, fully annotated corpus of learner English that is freely available for research purposes. The goal of the corpus is to provide a large data resource for the development and evaluation of grammatical error correction systems. Although NUCLE has been available for almost two years, there has(More)

The quality of parts produced by a composite tape-laying process is sensitive to the contact force exerted and the abutment of adjacent tape courses kept when the tapes are laid. Thus, a prerequisite for a high performance laying process automated by means of industrial manipulators is the ability to regulate laying force and position precisely in the(More)
I In this paper, a fault diagnostic method is proposed ,for autobody assembly jixtures. This method uses measurement data to detect and isolate dimensional ,faults of part caused by jkture. The proposed method includes a predetermined variation puttern 481 09-21 25 model and a fault mapping procedure. The variation pattern model is bused on CAD information(More)
