Syntax parse trees are a method of representing sentence structure and are often used to provide models with syntax information and enhance downstream task performance. Because grammar and syntax are inherently linked, the incorporation of syntax parse trees in GEC is a natural solution. In this work, we present a method of incorporating syntax parse trees for Grammatical Error Correction (GEC). Building off a strong sequence-to-sequence Transformer baseline, we present a unified parse integration method for GEC that allows for the use of both dependency and constituency parse trees, as well as their combination - a syntactic graph. Specifically, on the sentence encoder, we propose a graph encoder that can encode dependency trees and constituent trees at the same time, yielding two representations for terminal nodes (i.e., the token of the sentence) and non-terminal nodes. We next use two cross-attentions (NT-Cross-Attention and T-Cross-Attention) to aggregate these source syntactic representations to the target side for final corrections prediction. In addition to evaluating our models on the popular CoNLL-2014 Shared Task and JFLEG GEC benchmarks, we affirm the effectiveness of our proposed method by testing both varying levels of parsing quality and exploring the use of both parsing formalisms. With further empirical exploration and analysis to identify the source of improvement, we found that rich syntax information provided clear clues for GEC; a syntactic graph composed of multiple syntactic parse trees can effectively compensate for the limited quality and insufficient error correction capability of a single syntactic parse tree. 相似文献

This paper extends organizational communication research by considering external organizational issues. It analyzes the interorganizational network of real estate companies and the relationship of their network positions to organization‐level perceptions about the system. The network is divided into: (1) one group of organizations that were sparsely connected, and (2) stand‐alone organizations that were isolated from the prevailing group and each other. This interorganizational network analysis is grounded in institutionalization and resource dependence theory, vis‐à‐vis overlapping perceptions of the system, elicited by answers to open‐ended interviews. Results indicate institutionalized perceptions occurred for the group‐member organizations through indirect exposure to information in the environment. Specifically, organizations who shared similar roles in the network have convergent interpretations. These data support Mizruchi's (1993) theory that prominent organizations are more similar than those who have more peripheral roles in a network. 相似文献

Objective： To introduce the clinical effect among patients who received an unwrapped orbital implant with high density porous polyethylene material （Medpor） after enucleation or evisceration. Methods： Retrospective analysis of a series of 302 patients with anophthalmia who underwent placement of an unwrapped high density porous polyethylene orbital implant. We compared the patients （n=180） who accepted primary implant placement with those （n=122） who accepted secondary implant placement. Parameters evaluated included： age at time of surgery, date of surgery, sex, implant type and size, surgery type, the surgical procedure and technique performed, and complications. Results： The time of follow-up ranged from 2.0 to 58.0 months （mean 32.5 months）. A total of 5 of 302 （1.66%） cases had documented postoperative complications. The following problems were noted after surgery： implant exposure, 3 patients （0.99%）; implant removed due to orbital infection, 1 patient （0.34%）; ptosis, 1 patient （0.34%）. There were no significant complications＇observed in other 297 cases and all implants showed good orbital motility. The clinical effect of primary implant placement is better than that of secondary placement. Conclusion： High density porous polyethylene material can be used successfully as an unwrapped orbital implant in anopthalmic socket surgery with minimal complications. The material is well tolerated, nonantigenic and has low rate of infection and migration. 相似文献

目前社区矫正的试行受阻于体制转型迟缓且前景不明。与传统体制相比,贴近基层法律服务的司法行政部门更易树立以人为本的矫正观;以假释人员为主的矫正对象结构决定了司法行政部门接手社区矫正的必要性;持续扩大社区处遇对象更须充分利用其管理优势。因此社区矫正主体应以司法行政机构为主导,形成公安、检察、法院联动体制;该体制还须尽量吸纳社会力量,最终以＂小政府、大市场＂的政府购买模式完成对特殊类群的观护及督导。 相似文献

In fringe projection profilometry, the nonlinear intensity response caused by the γ effect of a digital projector results in periodic phase error and therefore measurement error. Previous error correction methods are largely based on the calibration of single γ value. However, in practice, it is difficult to accurately model the full range of the intensity response with a one-parameter γ function. In this paper, a compensated intensity response curve is generated and fitted with the constrained cubic spline. With the compensated curve, the full range of the nonlinear intensity response can be corrected and the periodic phase errors can be removed significantly. Experimental results on a flat board confirm the average root mean square （RMS） of the phase error which can be reduced to at least 0.0049 rad. 相似文献
