中文电子病历的分词及实体识别研究

[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。     

时间词“明日”“明天”的多维度考察

在共时层面上,时间词"明日""明天"在句法组合以及语用表达方面都有所不同,因此,不能认定两者是完全等同的;从历时层面看,两者也呈现出一个此消彼长的演变过程,同时这种状况也在方言调查中得到证实。     

Exploring mechanisms of rapid automatized naming to arithmetic skills in Chinese primary schoolers

Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation. Using a sample of Chinese primary school students (N = 170), results showed that while RAN was associated with all key aspects of arithmetic skills, the relations of RAN–arithmetic procedure and RAN–word problems may be dependent on that of RAN–arithmetic fluency. Supporting the processing speed hypothesis, results further suggested that processing speed may underlie the relation between RAN and arithmetic performance. Findings made unique contribution to understanding the effect of RAN on arithmetic performance and cognitive mechanisms that may underpin this association in the context of Chinese culture.     

How can children with mild literacy difficulties be supported at the transition to secondary school? A small‐scale quasi‐experimental study

There is evidence that pupils with weak literacy skills struggle on transition to secondary school. Many experience a drop in attainment in the summer break between the two. A British government‐funded programme of rigorously designed research on boosting literacy at transition had (by 2015) found only four of 15 interventions evaluated had positive effects. This small‐scale quasi‐experimental study investigated the effectiveness of support for pupils with mild literacy difficulties on transition to secondary school. Thirty‐two pupils in three schools were involved; half received the programme. Pairs were matched on reading, spelling, age and gender. Intervention was designed around the individual needs of each pupil, focusing variously on language skills, writing, reading and spelling. The group receiving the programme made modest gains in spelling, reading efficiency and single word reading. The comparison group lost ground, relatively, in all three areas. The results suggest a promising line for more rigorous investigation.

吴闽语进行体和持续体的语法化序列分析

莆仙方言的进行体和持续体标记来源于处所词,这是吴语和闽语的共同特征.但莆仙方言的这两种体标记来源于处所代词"即、许",而不是方位后缀或动介词,这又不同于吴语与闽语的其他方言.本文先描写莆仙方言的进行体和持续体特征,然后结合吴闽语其他八种方言的资料,分析进行体和持续体标记的语法化序列,从而观察其演变发展的过程.     

黄冈方言的后加成分"着"

在黄冈方言中,“着”可附在时间词或动词短语之后,构成具有动词性的“着”字结构,相当于“等到……以后再……”或“等到……再说”。成都方言“哆”字结构与黄冈方言“着”字结构性质相同,二之间可能存在一定的渊源关系。“哆”、“着”都不是“再说”衍生出来的;关于“着”的来源,杨永龙（2002）所说较为可信。
