专业术语的识别与自动抽取对于提升专业信息检索精度,构建领域知识图谱发挥着重要基础性作用。为进一步提升中文专业术语识别的精确率和召回率,提出一种端到端的不依赖人工特征选择和领域知识,基于谷歌BERT预训练语言模型及中文预训练字嵌入向量,融合BiLSTM和CRF的中文专业术语抽取模型。以自建的1278条深度学习语料数据为实验对象,该模型对术语提取的F1值为92.96%,相对于传统的浅层机器学习模型(如左右熵与互信息算法、word2vec相似词算法等)和BiLSTM-CRF深度神经网络模型的性能有较为显著的提升。本文也给出了模型应用的具体流程,能够为中文专业术语库的构建提供实践指南。  相似文献   

Librarians collaborate successfully with nursing faculty and a writing centre to support nursing students doing professional doctorates     

Matthew Bernstein  Linda Roney  Meredith Kazer  Elizabeth H. Boquet 《Health information and libraries journal》2020,37(3):240-244

This study explores how a three‐way collaboration between a University library, writing centre and faculty created avenues of training and support for students within a Doctor of Nursing Practice (DNP) program in an American University. The role of each partner involved in the collaboration is discussed alongside the profile of the DNP students. Lesson planning and classroom techniques for DNP information literacy classes are described and feedback from the partners and the students are discussed. The study confirms that collaboration is effective in improving research and writing skills. D.I.  相似文献   

Medical librarian 2.0     

Connor E 《Medical reference services quarterly》2007,26(1):1-15

Web 2.0 refers to an emerging social environment that uses various tools to create, aggregate, and share dynamic content in ways that are more creative and interactive than transactions previously conducted on the Internet. The extension of this social environment to libraries, sometimes called Library 2.0, has profound implications for how librarians will work, collaborate, and deliver content. Medical librarians can connect with present and future generations of users by learning more about the social dynamics of Web 2.0's vast ecosystem, and incorporating some of its interactive tools and technologies (tagging, peer production, and syndication) into routine library practice. doi: 10.1300/J115v26n01_01.  相似文献   

Income is not enough: incorporating material hardship into models of income associations with parenting and child development   总被引：2，自引：0，他引：2  

Gershoff ET  Aber JL  Raver CC  Lennon MC 《Child development》2007,78(1):70-95

Although research has clearly established that low family income has negative impacts on children's cognitive skills and social-emotional competence, less often is a family's experience of material hardship considered. Using the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N=21,255), this study examined dual components of family income and material hardship along with parent mediators of stress, positive parenting, and investment as predictors of 6-year-old children's cognitive skills and social-emotional competence. Support was found for a model that identified unique parent-mediated paths from income to cognitive skills and from income and material hardship to social-emotional competence. The findings have implications for future study of family income and child development and for identification of promising targets for policy intervention.  相似文献   

Processes of language acquisition in children with autism: evidence from preferential looking     

Swensen LD  Kelley E  Fein D  Naigles LR 《Child development》2007,78(2):542-557

Two language acquisition processes (comprehension preceding production of word order, the noun bias) were examined in 2- and 3-year-old children (n=10) with autistic spectrum disorder and in typically developing 21-month-olds (n=13). Intermodal preferential looking was used to assess comprehension of subject-verb-object word order and the tendency to map novel words onto objects rather than actions. Spontaneous speech samples were also collected. Results demonstrated significant comprehension of word order in both groups well before production. Moreover, children in both groups consistently showed the noun bias. Comprehension preceding production and the noun bias appear to be robust processes of language acquisition, observable in both typical and language-impaired populations.  相似文献   

Children with autism illuminate the role of social intention in word learning   总被引：2，自引：0，他引：2  

Parish-Morris J  Hennon EA  Hirsh-Pasek K  Golinkoff RM  Tager-Flusberg H 《Child development》2007,78(4):1265-1287

To what extent do children with autism (AD) versus typically developing children (TD) rely on attentional and intentional cues to learn words? Four experiments compared 17 AD children (M age=5.08 years) with 17 language- and 17 mental-age-matched TD children (M ages=2.57 and 3.12 years, respectively) on nonverbal enactment and word-learning tasks. Results revealed variability in all groups, but particularly within the AD group. Performance on intention tasks was the most powerful predictor of vocabulary in the AD group but not in the TD groups. These findings suggest that word learning cannot be explained exclusively by either attentional or intentional processes, and they provide evidence of a special role for intentional understanding in the vocabulary development of AD children.  相似文献   

Do infants need social cognition to act socially? An alternative look at infant pointing     

D'Entremont B  Seamans E 《Child development》2007,78(3):723-728

Tomasello, Carpenter, and Liszkowski (2007) present a comprehensive review of the infant pointing literature. They conclude that infant pointing demonstrates communicative intent from its onset, at about 1 year of age. In this commentary, it is noted that for infants to understand communicative intent, they must have a concept of self and others as intentional agents. Evidence is reviewed to argue that this is not possible until 18-24 months of age. A leaner explanation of how infants might initially succeed in pointing tasks without understanding communicative intent is considered.  相似文献   

Prevalence of child sexual abuse reported by a cross-sectional sample of New Zealand women   总被引：1，自引：0，他引：1  

Fanslow JL  Robinson EM  Crengle S  Perese L 《Child abuse & neglect》2007,31(9):935-945

OBJECTIVE: The objective is to describe the prevalence of child sexual abuse (CSA) among women in New Zealand, document ethnic specific rates, and outline the frequency of abuse experienced and the most commonly identified perpetrators. Associations between CSA and later adverse consequences were also explored. METHODS: Retrospective report from a random sample of 2,855 women aged 18-64 years old in two regions in New Zealand. Face-to-face interviews with one randomly selected woman from each household were conducted. RESULTS: The overall prevalence rates for CSA were 23.5% for women from the urban region and 28.2% from the rural region. In both urban and rural regions, Māori women more frequently reported experiences of CSA than women from European and other ethnic groups (urban: 30.5% vs. 17.0% and rural: 35.1% vs. 20.7%). The median age of onset of the abuse was 9 years, and the median estimated age of the abuser was 30 years. Half of those who experienced CSA reported that it occurred once or twice, 27% "a few times," and 23% "multiple times." Sole perpetrators were involved in 83% of cases. The majority of cases were perpetrated by a family member, most frequently male. Compared with non-victims, victims of CSA were twice as likely to experience later intimate partner violence and violence by others. CONCLUSIONS: This study reports on a large, population-based sample in an ethnically diverse population in New Zealand, providing the first ethnic-specific rates of CSA available. Findings suggest important priorities for prevention and intervention activities.  相似文献
