基于词汇链的关键词自动标引方法

关键词自动标引是一种识别有意义且具有代表性片段或词汇的自动化技术。关键词自动标引可以为自动摘要、自动分类、自动聚类、机器翻译等应用提供辅助作用。本文利用基于知网的词语语义相关度算法对词汇链的构建算法进行了改进,并结合词频和词的位置等统计信息,进行关键词的自动标引。实验证明,该方法可以有效的进行关键词的自动标引。

图书内容主题索引的自动编制实验

针对现有索引软件一般只能进行字面标引而不能实现概念标引的不足,提出了一个基于概念标引的图书内容主题索引自动编制方案,即将图书章节细化后,利用基于单篇文献的自动标引系统进行图书主题标引。通过三种标引系统对实验语料的标引结果统计来选择标引系统;其次通过对篇章结构分析,提出基于标题符号的标引源自动识别方案,同时给各标引源设定权重,提出主题词标引流程;最后还探讨了标引单元确定以及索引地址设计。实验表明,基于N-gram方法的图书内容主题索引的自动编制方法是可行的。

婴儿视觉注意的发展

近年来，研究对婴儿的视觉注意进行了大量研究，得到很多有价值的发现。这些发现围绕婴儿注意功能的4个方面，即警觉、空间定向、对物体特征的注意和内源性注意，描述了婴儿视觉注意的发展过程．婴儿出生时，身上已分化出各种注意功能的初级形式，但是，每种注意功能都有不同的发展时期。主要表现在：从出生到2个月，婴儿的警觉状态发生并发展；从2或3个月6个月左右，婴儿的空间定向和物体注意功能有很大的变化；从5或6个月以后，婴儿的内源性注意功能变化明显。

迟子建的地域情缘——试析黑土地文化对迟子建及其小说创作的影响

在活跃于当代文坛上的东北作家中,迟子建是一位受地域文化影响比较明显的女作家。东北特有的黑土地文化造就了她独特的创作风格,使她始终以对生活朴素的理解、母性的情怀以及民间的视角重彩涂抹着故乡的地域风情,始终执著而又诗意地表达着对黑土地的深情以及对故土生命的热爱。本文试从创作动因、创作视野、情感观照以及叙述视角等角度探究黑土地文化对其创作的影响。     

Developing an inclusive learning environment for students with visual impairment in higher education: progressive mutual accommodation and learner experiences in the United Kingdom

Abstract

Drawing on the findings of a unique longitudinal qualitative study, this article investigates the experiences of 32 young people with visual impairment (VI) in higher education (HE) in the United Kingdom (UK) to explore how well they were able to participate on their courses. We propose and apply a Bioecological Model of Inclusive HE to interpret these experiences and examine how accommodations were made to facilitate participation. Focusing specifically on ‘curriculum access’, the results highlight the importance of accommodations that are progressive and mutual. The accommodations come in many forms and include: the provision of resources through nationally based schemes (e.g. the Disabled Students Allowance in the UK); the support, adjustments and anticipatory adjustments HE institutions should provide; and the study skills and independence skills individual students should be able to act upon. The findings showed that while the majority of participants reported that their HE institution made some adjustments to enable them to access their course, a lack of anticipatory adjustments created barriers. The most common compensation for this barrier was to provide deadline extensions, often resulting in additional pressure on other aspects of the course. Interviews with university staff highlighted limited specialist knowledge and resources within their institutions to enable accommodations for students with VI and, more broadly, understanding of how to develop an inclusive learning experience. The findings also highlighted expectations made of the learner, particularly being able to explain their required adjustments and having well-developed independent study skills. The paper has particular relevance to HE institutions in that it provides a model to aid interpretation of their role in creating an inclusive learning experience for students with VI. It also offers a reference point for professionals supporting young people with a broader range of disabilities in considering how best to prepare them for life after compulsory education.     

初中生对几何证明的认识

直观实验和几何证明是几何教学中常用的两种重要方法.学生对几何证明的本质还缺乏认识.学生认为直观实验不能算是几何证明,一方面因为直观实验存在误差,另一方面直观实验只能从不完全归纳中得出结论.
