浅析智能标签的发展与应用   总被引：3，自引：0，他引：3  

季慎有 《湖南科技学院学报》2005,26(8):52-54

智能标签以无线射频方式进行非接触的自动识别和数据传送,是未来应用前景最广阔的射频识别产品。它通常由读写器、RFID卡及相关天线构成,具有系列优点和广阔的国际背景,在商业企业、物流管理、电子票证等领域得以广泛应用．只要解决好编码体系多样性、成本相对过高、应用环境和解决方案不够成熟等制约因素,智能标签在我国企业信息化过程中必将发挥更大作用。  相似文献

跨项选材理论与实践发展： 历程回顾、现实审思与未来方向          下载免费PDF全文

孙民康 《河北体育学院学报》2021,35(1):61-68

运动员选材与培养是保持竞技体育竞争力的基本要素,传统选材与培养(以下简称传统选材)模式具有成材率低、投资风险高、选材范围狭窄等局限性,间接催生了跨项选材与培养(以下简称跨项选材)模式的发展。运用文献资料法和逻辑分析法,对跨项选材的实践案例与研究成果进行系统梳理、分析,认为其主要经历了萌芽期(1932—1979年)、探索期(1980—2005年)、初步定型期(2006—2016年)、快速发展期(2017至今)。指出,跨项选材相关研究主要围绕为什么跨项选材、何时跨项选材、怎样跨项选材、什么人跨项、哪些项目跨项五方面展开。虽然相关研究已达成诸多共识,但关于跨项选材的起始概念、目的意义、实践的落脚点等核心问题还存在争议。指出,指导传统选材的刻意练习理论存在缺乏竞争、忽视兴趣培养等问题,无组织跨项的难度不断提高,成功愈发难以复制。而世界各国开展的有组织的跨项选材已显现成果,这为我国跨项选材工作提供了很好借鉴。最后,提出跨项选材理论体系的构建需要不断引入新的理论,多学科的交叉与融合创新是跨项选材理论未来的发展方向。  相似文献

冯立杰  王清华  王金凤  张珂  张世斌 《科技管理研究》2022,(23)

为精准识别技术创新机会,提出一种基于SAO语义分析与多维技术创新地图的技术创新机会识别方法。首先融合关键词分析和SAO语义分析方法剖析影响技术创新的要素,并以“链”结构梳理创新要素的层级关系,形成层次分明的技术形态；然后以多维技术创新地图为导航,基于维法耦合原理实现概念化和具象化两层技术创新机会的识别；最后以富钛料制备技术创新机会识别为例,检索并搜集392条专利为数据集。实证结果识别出3个概念化和6个具象化技术创新机会,验证了该方法的可行性,可为企业准确研判技术创新机会以不断获取技术先行者优势提供有益参考。  相似文献   

The potential of immersive virtual reality to enhance learning: A meta-analysis     

《Educational Research Review》2022

Research on the impact of immersive virtual reality (I-VR) technology on learning has become necessary with the decreasing cost of virtual reality technologies and the development of high-quality head-mounted displays. This meta-analysis investigates the overall effect size by combining the results of primary experimental studies that reveal the effect of I-VR on learning outcomes. Besides, effect sizes were calculated based on measuring moment, types of measurement, education level, the field of education, control group educational resources, and immersion type subgroups. One hundred five independent results were calculated from 48 primary studies published between 2016 and September 2020, including 39 randomized controlled trials and nine quasi-experimental studies. The sample size of primary studies includes 3179 students, 847 from K12, and 2332 from higher education. Random effects model was used in the calculation of effect size. As a result of the meta-analysis, it was determined that the overall effect size on the learning outcomes of I-VR was small (g = 0.38). Additionally, according to the subgroup analysis results, it was revealed that I-VR significantly differentiated effect size based on educational level, the field of education, and computer-based/traditional sources. There was no significant difference in terms of the other subgroups.  相似文献   

From statistical methods to deep learning,automatic keyphrase prediction: A survey     

《Information processing & management》2023,60(4):103382

Keyphrase prediction aims to generate phrases (keyphrases) that highly summarizes a given document. Recently, researchers have conducted in-depth studies on this task from various perspectives. In this paper, we comprehensively summarize representative studies from the perspectives of dominant models, datasets and evaluation metrics. Our work analyzes up to 167 previous works, achieving greater coverage of this task than previous surveys. Particularly, we focus highly on deep learning-based keyphrase prediction, which attracts increasing attention of this task in recent years. Afterwards, we conduct several groups of experiments to carefully compare representative models. To the best of our knowledge, our work is the first attempt to compare these models using the identical commonly-used datasets and evaluation metric, facilitating in-depth analyses of their disadvantages and advantages. Finally, we discuss the possible research directions of this task in the future.  相似文献
