学术文本词汇功能识别--基于标题生成策略和注意力机制的问题方法抽取 总被引：1，自引：0，他引：1
学术文本词汇功能识别的目的是实现学术文本中表征问题、方法和对象等词汇的抽取。针对传统识别方法中训练难以获取所导致的识别准确率低、召回率有限和泛化能力差等问题,本研究提出了一种基于深度学习和标题生成策略的学术文本词汇功能识别方法,将任务形式由信息抽取转化为特定形式的标题生成问题。本研究采用构建seq2seq模型和引入注意力机制的方式捕获词汇多层语义信息,最终实现学术文本中问题和方法指代词的生成和获取。实验结果表明,通过应用深度学习方法和标题生成策略,本研究提出的模型能够从摘要中有效识别学术文献的主要研究问题和主要研究方法,并较已有方法在识别效果上有明显提升。 相似文献

Academic librarians have long been responsible for teaching information literacy competencies on college campuses, even as many are hesitant to accept the title of teacher. With inadequate instructional design preparation and one-shot sessions serving as a popular, if limited, instructional medium, librarians' design processes are often developed on the job and infrequently explored in the literature. Previous research has examined specific design models and instructional strategies, but few studies were found that determined how academic librarians select and implement these design decisions within the context of a one-shot. This Delphi study described academic librarians' design processes in an effort to develop practical takeaways for training and design of one-shot sessions using expert consensus. This study found (1) academic librarians find their master's degree curriculum lacking in instructional preparation; (2) participants preferred professional development that allowed for observation and direct experience; (3) consensus centering objectives in design decisions; (4) backward design was a frequently used model due to its ease of use, flexibility, and emphasis on objectives; and (5) the one-shot environment significantly impacted participants' design processes leading to modifications in their teaching. This paper concludes with a discussion of the implications for practitioners and recommendations for future research directions. 相似文献

The history, philosophy, and methodology of a unique specialized medical information center are reported. The Clinical Neurology Information Center is an educational information service (giving its audience information which can be the basis for formulating their own questions) rather than an instructional information service (giving information in reply to questions). Clinical, as well as basic neuroscience, information is culled by professional neurologists from 855 medical periodicals. The essence of each article is summarized in a single sentence ("terse conclusions") or a bibliographic reference only is given; this material is published every two weeks in the Concise Clinical Neurology Review (CCNR). The format of the CCNR is such that the reader should be able to scan a very large amount of current literature by investing only twenty to thirty minutes every two weeks. The values of this system as well as some of its problems are discussed. 相似文献

Information literacy for faculty, doctoral students and other research-based graduate students, post-docs, and other original researchers is complex. There are fundamental differences between the processes of inquiry used by original researchers as compared to students or even faculty who are synthesizing information to find answers. Original research is different from information synthesis for discovery. Therefore, the information literacy processes to train and support those researchers are different. Analysis of the inquiry-oriented parts of the current and emerging information literacy Standards and Framework shows significant differences in the approach needed for teaching research information literacy. Promising instructional outcomes for information literacy training based around original research include gap analysis, theoretical and methodological discovery, and practical skills like funding search and analysis. 相似文献

In this paper, consideration of the information aspects of the ontology of anthropogenic systems is continued. An additional category of boundary system information processes is introduced in the information base of anthropogenic systems that was considered earlier. The receptive information genesis underlying these processes is examined. The formulation of a interpretation model that describes boundary-information problems is proposed. It is concluded that information-decision systems have two components, i.e., a universal mechanism of one of the categories of system information problems and the domain-specific content of the respective models. 相似文献

The current national education crisis makes it imperative for educators to identify relevant research and development on new and innovative instructional techniques. The United States Department of Defense (DOD) has significant education and training responsibilities that could be useful in providing instructional technology for transfer to civilian applications. However, we propose that there is a gap between the holdings of ERIC, the primary education database, and NTIS, the main database for information on the activities of Federal government agencies, including the DOD. Much information with a Federal derivation may not be cited in ERIC. We develop a series of search statements based on these propositions. These are applied to each database and the results analyzed. Findings substantiate at least a limited gap that must be recognized by educators and information professionals and that has implications for testing holdings of other databases. 相似文献

建立整合的知识结构贮藏库(英文) 总被引：2，自引：0，他引：2
不同的知识库对概念的语义与词义的表达都会不同。用户要在检索中使用它们就会有困难。该论文介绍了一个知识贮藏库的整合模型。这个模型全部利用开放式软件(Open-SourceSofware)以及可扩展标记语言(XML)和概念分类体系(Ontologies)的技术建成。它提供了知识库之间的知识结构映射,也为用户提供图表式界面以方便用户对知识库整合的直接参与。由于这一模型是以用户为中心,以知识结构为重点,它将为建立下一代的知识网络提供一个范例。 相似文献

Principles of learning and instructional theories are discussed and related to the challenges and problems of instruction in library user education. A suggested model of library instruction is outlined along with the strong recommendation that librarians be aggressively active in promoting information literacy before library instruction begins. Being knowledgeable and keeping abreast of new theories and principles of learning and acting upon these principles will improve instruction. Librarians must realize that information literacy is a "process" and cannot be accomplished in one lecture. 相似文献
