Relevance of the SFU Review_SP-NEG corpus annotated with the scope of negation for supervised polarity classification in Spanish

Up to now, negation is a challenging problem in the context of Sentiment Analysis. The study of negation implies the correct identification of negation markers, the scope and the interpretation of how negation affects the words that are within it, that is, whether it modifies their meaning or not and if so, whether it reverses, reduces or increments their polarity value. In addition, if we are interested in managing reviews in languages other than English, the issue becomes even more problematic due to the lack of resources. The present work shows the validity of the SFU Review_SP-NEG corpus, which we annotated at negation level, for training supervised polarity classification systems in Spanish. The assessment has involved the comparison of different supervised models. The results achieved show the validity of the corpus and allow us to state that the annotation of how negation affects the words that are within its scope is important. Therefore, we propose to add a new phase to tackle negation in polarity classification systems (phase iii): i) identification of negation cues, ii) determination of the scope of negation, iii) identification of how negation affects the words that are within its scope, and iv) polarity classification taking into account negation.  相似文献   

Evaluation of treatment effect estimates in single‐case experimental research: comparison of twelve overlap methods and visual analysis     

Serife Yucesoy‐Ozkan  Salih Rakap  Emrah Gulboy 《British Journal of Special Education》2020,47(1):67-87

The purpose of this study was to compare 12 commonly‐used nonoverlap methods with each other and with the results of visual analysis. Data were obtained from 25 studies focused on embedded instruction and schema‐based instruction and included a total of 101 graphs. Treatment effect estimates using 12 nonoverlap methods were calculated for each graph by hand or using an online calculator. Five experts conducted visual analysis of each graph. Results showed that strong agreements existed between visual analysis and PND, Tau_NOVLAP and Tau‐U when raw data were analysed, and PND, PNCD and PEM‐T when categorised data were analysed. Of the 12 methods investigated, PND had the highest agreement rate with visual analysis, followed by PEM‐T, PAND, PNCD, IRD, NAP and Tau_NOVLAP. Overall, visual analysis appeared to be more conservative, as most nonoverlap methods overestimated the treatment effect. Additional research is needed to replicate and potentially validate the findings of this study.  相似文献   

Design Considerations for an Intensive Autism Treatment Centre          下载免费PDF全文

Neil Deochand  Alissa A. Conway  R. Wayne Fuqua 《Support for Learning》2015,30(4):327-340

Individuals with autistic spectrum disorder (ASD) who display severe and challenging behaviour sometimes require centre‐based intensive applied behaviour analysis (ABA) therapy to meet their health, safety and educational needs. Unfortunately, despite the need for centre‐based treatment, there is a paucity of empirical research on building and programme design features that influence positive behavioural outcomes for individuals with ASD. We surveyed professionals who had experience providing services to the ASD population regarding the building design and policy features that could facilitate treatment. This article highlights the features that were highly endorsed as beneficial in the design of an intensive ASD treatment facility, with the intended purpose of discovering which features create an environment in which the individuals can more easily transition into an appropriate mainstream learning environment. It is hoped that the results of the survey will be helpful to those developing ASD treatment facilities and allow them to circumvent trial and error that could occur when building a centre from the ground up.  相似文献   

分级诊疗背景下的基层医务人员教育模式探讨--以北京市C区为例     

齐心  杨燕绥 《中国教育技术装备》2020,(4):83-84,92

医疗卫生体制改革的关键目标是强化基层医疗机构,只有基层医疗机构的诊治能力得到提升,才能强化患者对基层医生业务的信任;只有有效落实基层首诊制,才能更好地推进分级诊疗制度建设[1]。通过对北京市C区医疗机构和基层医务人员的总体现状研究,发现对医务人员的教育方法单一,形式陈旧,无法服务于分级诊疗的要求。以C区数据为切入点,剖析基层医疗机构教育工作的困境,探索提出对基层医务人员的教育方法。  相似文献

论我国强制医疗制度之完善   总被引：2，自引：0，他引：2

统计表明,精神病人犯罪已成为我国不可回避的社会问题.为有效地预防已经造成危害结果的精神病人继续危害社会,有必要对其强制医疗.我国的相关立法却过于宽泛,缺乏可操作性.在比较、借鉴外国(或地区)立法例的基础上,我国的强制医疗制度应该完善起来.  相似文献
