文化遗产大数据二维分类框架研究     

曾熙  谭旭  王晓光 《图书情报知识》2020,(1):84-93

[目的/意义]数字化浪潮催生了类型繁多的海量文化遗产大数据,合理的分类已经成为文化遗产大数据科学管理与有效利用的关键。[研究设计/方法]根据文化遗产与大数据的基础理论提出了文化遗产大数据的概念及特征,并采用文献调研法对文化遗产数据分类现状进行探讨。[结论/发现]分类焦点应从具体类别的文化遗产信息向文化遗产大数据这一类资源整体转变;同时,现有分类体系中出现的维度单一、粒度粗糙、类目设置不严谨等问题也亟需解决。[创新/价值]采用组配分类法,以文化遗产大数据为研究对象,以文化遗产领域特征和数据特性为切入点,提出了基于文化遗产领域特征与数据特性的二维分类框架。  相似文献   

Identification of highly-cited papers using topic-model-based and bibliometric features: the consideration of keyword popularity     

《Journal of Informetrics》2020,14(1):101004

The number of received citations have been used as an indicator of the impact of academic publications. Developing tools to find papers that have the potential to become highly-cited has recently attracted increasing scientific attention. Topics of concern by scholars may change over time in accordance with research trends, resulting in changes in received citations. Author-defined keywords, title and abstract provide valuable information about a research article. This study performs a latent Dirichlet allocation technique to extract topics and keywords from articles; five keyword popularity (KP) features are defined as indicators of emerging trends of articles. Binary classification models are utilized to predict papers that were highly-cited or less highly-cited by a number of supervised learning techniques. We empirically compare KP features of articles with other commonly used journal-related and author-related features proposed in previous studies. The results show that, with KP features, the prediction models are more effective than those with journal and/or author features, especially in the management information system discipline.  相似文献   

试论王尔德童话的"三美"     

黄俏 《延安教育学院学报》2007,21(2):21-22

王尔德童话的"三美"指幻想美、诗意美和感伤美.幻想美是他童话的基本特征,这是由童话的特征所决定的.诗意美体现着他对童话语言的运用.而他的童话总给人以感伤美,这是作家"世纪末"情绪的一种反映,是他童话的审美特征.  相似文献   

论“七艺”之流变     

沈文钦 《复旦教育论坛》2007,5(1):34-39

"七艺"是西方教育史上的核心概念之一,也是西方很长时间内的主要教育内容,与自由教育、通识教育等理念密不可分.本文将"七艺"的演变分为古希腊、古罗马、中世纪早期、中世纪晚期四个阶段,探讨了这一概念形成的历史过程,并通过课程的视角考察其在西方教育中的制度化过程.文章指出,笼统地说"古希腊罗马的七艺"是不准确的,"七艺"的概念成型于古罗马晚期,并与基督教有不可割裂的联系,它主要是一个属于中世纪与基督教的概念.  相似文献

HSK口部动词研究及启示     

杜婷 《安庆师范学院学报(社会科学版)》2011,30(5):31-35

口部动词是动词的特殊小类,也是对外汉语集合式词汇教学的一个重要集合。通过对《汉语水平考试词汇与汉字等级大纲》中口部动词的研究发现：口部动词可分为四类,且义项丰富,多义口部动词义项泛化的基本形式为：＂口部动作义→一般口部动作义→引申义或比喻义＂;口部动词的使用频度与大纲的设计基本一致。根据这一研究结果,对外汉语口部动词的教学可以遵循区分频度原则、分别释义原则和汉外对比原则以提高教学效果,并可以针对不同级别的学生确定不同的教学设计思路。  相似文献   

Length-based vehicle classification in multi-lane traffic flow     

于洋  于明  阎刚  翟艳东 《天津大学学报(英文版)》2011,17(5):362-368

For the realtime classification of moving vehicles in the multi-lane traffic video sequences, a length-based method is proposed. To extract the moving regions of interest, the difference image between the updated background and current frame is obtained by using background subtraction, and then an edge-based shadow removal algorithm is implemented. Moreover, a thresholding segmentation method for the region detection of moving vehicle based on location search is developed. At the estimation stage, a registration line is set up in the detection area, then the vehicle length is estimated with the horizontal projection technique as soon as the vehicle leaves the registration line. Lastly, the vehicle is classified according to its length and the classification threshold. The proposed method is different from traditional methods that require complex camera calibrations. It calculates the pixel-based vehicle length by using uncalibrated traffic video sequences at lower computational cost. Furthermore, only one registration line is set up, which has high flexibility. Experimental results of three traffic video sequences show that the classification accuracies for the large and small vehicles are 97.1% and 96.7% respectively, which demonstrates the effectiveness of the proposed method.  相似文献   

皎然诗歌批评标准和诗歌分类标准的矛盾性和统一性     

李艇 《漯河职业技术学院学报》2011,10(1):41-43

皎然是中唐著名的诗人和诗论家,他的《诗式》是唐代诗论发展史上的一座丰碑,它不仅总结了唐诗由兴而盛的成功经验,也反映了“安史之乱”后唐诗由盛而衰的过程。在《诗式》中,他提出了“五格论诗”的诗论方法,这“五格论诗”的方法和皎然的文艺思想有着密切的联系,既表现出方法自身的矛盾,也表现出统一于文艺思想的倾向,既显出矛盾性,也显出统一性。本文拟就皎然诗评标准内在的矛盾性和统一性提出看法,以求教于方家。  相似文献   

Characteristics of electricity consumption of different industry types considering atmospheric condition

Reducing greenhouse gases (RHG) is going on actively in the international movement. In the field of architecture, RHG is an inevitable work. To establish a plan for RHG, firstly we need to reduce energy consumption. Greenhouse gas generated by energy consumption is the main cause of global warming. For this we should know that how much electricity consumption we use. The research targets of this study are commercial buildings with various businesses. Their electricity consumption was analyzed by business units rather than buildings. Each business was divided into 13 sectors according to industrial classification and electricity consumption was analyzed for each industry. For commercial buildings, the electricity consumption is done by the private sector and construction management is an autonomy system in private instead of an integrated management system. In this study, we classified and analyzed the electricity consumption characteristics according to collected data, analyzed the relationship between the electricity consumption with atmospheric temperature through SPSS, and developed an electricity prediction model.  相似文献
