中文电子病历的分词及实体识别研究   总被引:1,自引:0,他引:1  
[目的/意义]健康医疗大数据是我国重要的基础性战略资源,本研究对中文电子病历分词与实体识别的探讨与实证较好地完成了医疗数据的信息抽取任务,对今后医疗大数据在语义层面的应用发展具有重要意义。[方法/过程]本研究首先融合权威词表、官方标准、健康网站数据及其他医学补充词库构建了词语数量级达到10万的医学词表;然后对电子病历的字段进行分词,对比了jieba工具、导入词典后的jieba、无监督学习及AC自动机4种模型的分词效果;最后,以自动分词和人工标注结果为语料,实现基于条件随机场的电子病历实体识别研究,并比较不同实体类别以及不同文本特征下的实体识别效果,选出最优模板。[结果/结论]分词结果显示,AC自动机的效果最好,F值可达82%;实体识别结果表明,"检查"和"疾病"实体的识别效果最好,而"症状"的识别效果不太理想。  相似文献

The aim of this study is to determine changes in sedentary behaviour in response to extensive aerobic exercise training. Participants included adults who self-selected to run a marathon. Sedentary behaviour, total activity counts and physical activity (PA) intensity were assessed (Actigraph GT3X) for seven consecutive days during seven assessment periods (?3, ?2, and ?1 month prior to the marathon, within 2 weeks of the marathon, and +1, +2, and +3 months after the marathon). Models were fitted with multiple imputation data using the STATA mi module. Random intercept generalized least squares (GLS) regression models were used to determine change in sedentary behaviour with seven waves of repeated measures. Results: Twenty-three individuals (mean?±?Sx: 34.4?±?2.1y, 23.0?±?1.9% fat, 15 women, 8 men) completed the study. Marathon finishing times ranged from 185 to 344 minutes (253.2?±?9.6 minutes). Total counts in the vertical axis were 1,729,414 lower one month after the race, compared with two months prior to the race (peak training). Furthermore, counts per minute decreased by 252.7 counts·minute?1 during that same time period. Daily sedentary behaviour did not change over the seven assessment periods, after accounting for age, gender, per cent body fat, wear time, marathon finishing time, and previous marathon experience. This prospective study supports the notion that PA and sedentary behaviours are distinct, showing that sedentary behaviour was not impacted by high levels of aerobic training.  相似文献

Recognizing inconsistencies between the extant fear appeal theories and emotion literature, this research integrated cognitive appraisal theory and functional emotion theory into a fear appeal literature and proposed a model that describes a process through which both fear and anxiety can contribute to adaptive responses. Findings from an experiment (N = 927) supported the predictions. Fear and anxiety emerged as distinct constructs. Perceived susceptibility was a stronger predictor of anxiety than fear, while perceived severity was a stronger predictor of fear than anxiety. In addition, greater fear and anxiety led to greater response efficacy through increased motivation to obtain protection-related information and heightened attention to such information, thus mediating the threat and coping appraisal processes. The SEM model testing the predictions showed that perceived susceptibility had the strongest total effects on protection intention, followed by anxiety, perceived severity, and fear.  相似文献

Abstract

Global citizenship education (GCE) positions itself on the global arena as a transformative social justice oriented educational curriculum that addresses the political, social, economic and cultural inequalities brought about through colonisation and neoliberalism on the global and local levels. Through an exploration of the discourse, design and delivery of GCE in the young nation-state of South Korea, we argue that, in fact, GCE reinforces and maintains the hegemonic ideals of global capitalism; core-periphery global and local relationships; and dichotomous views of poverty and inequalities. We argue that these approaches reflect South Korea’s geopolitical realities, but that attitudes towards GCE in South Korea also reflect its cultural norms and values towards working together towards a common good. Ultimately, we call for a more nuanced approach to GCE scholarship in which we move away from theoretical divisions to practical applications of social justice that work within increasingly capitalist/neoliberal interests for a more inclusive world.  相似文献

There has been increasing recognition for the need to reform doctoral training practices to foster students’ personal epistemology. This study describes the design and evaluation of a learning experience designed to help students understand the scholarly publication process. Firstly, this study discusses the design of the learning experience, describing the collaborative process of writing an interdisciplinary publication using both online and face-to-face learning. Secondly, this study evaluates the effectiveness of the learning experience by examining students’ reflections. We show that participation in the learning experience helped students to develop their academic writing proficiency, collaboration and teamwork, intercultural competence, and ability to engage in reflective practice. Importantly, we show that each student also created more individualised knowledge, gaining insight into how they and others think. This study, therefore, demonstrates that personal epistemology can be fostered through collaboration in a doctoral writing group context.  相似文献

Abstract

This paper tries to analyze the historical change in the Third World in its emergent stage, in the authoritarian stage and in the current democratic stage and, thereafter, find a way to revive the Bandung spirit in the current globalization context. I define the Bandung spirit as one of a ‘non‐aligned self‐helped “organization against” the dominant powerful countries’; that is, spirit of ‘anti‐predominance’. This spirit has emerged on the base of such domestic orientation and realities as economic self‐reliance, nationally integrated political regime, convergence of the state and civil society around anti‐colonialism. However, according to intensification of the Cold War confrontation on the international level and its centrifugal influence, the early Third World changed to a ‘new’ authoritarian Third World. The Third World in this stage could be characterized by an exclusive authoritarian political regime, dependent‐developmentalist economic orientation and coercively repressed and mobilized, in the top‐down way, civil society. This authoritarian Third World began to be confronted with a strong struggle from the bottom for democratization. In order for democratization of the Third World to become its true revival in the context of globalization, the following tasks should be considered. First, the democratic Third World should be a great driving force for the institutionalization of the transnational public regulatory mechanism. Second, the democratic Third World countries try to go over a kind of ‘transformed’ dependent development strategy. Third, democratization should go along with recovery of political inclusiveness and openness of the state to civil society’s demands. Thereafter, I tried to construct globalist re‐interpretation of the Bandung, by way of conceptualizing the current globalization as imperial globalization, unlike the imperialist globalization which the historical Bandung wanted to confront. I argue that the Bandung spirit of collective self‐help organizations against the newly emerging dominant order should be revived in this worse imperial globalization context. In addition, I argue that a nationalist resistance is also one component of the multiple resistances in the current imperial globalization.  相似文献

In a previous study we found that students receiving feedback from multiple peers improve their writing quality more than students receiving feedback from a single expert. The present study attempted to explain that finding by analyzing the feedback types provided by experts and peers, how that feedback was related to revisions, and how revisions affected quality. Participants were 28 undergraduates who received feedback from a single expert (SE), a single peer (SP), or multiple peers (MP), thus forming three groups, respectively. The MP group received more feedback of all types. Non-directive feedback predicted complex repairs that the MP group made more than both other groups. Complex repairs were associated with improved quality.  相似文献
