基于专利引用跨越度计量的两国间间接创新合作机会发现     

李睿  青杨媚  范九江 《图书情报工作》2021,64(23):31-39

[目的/意义] 两个国家间的创新合作机会有些是显性直接的，有些是潜在间接的。在此试图构建一种计量和分析专利引用关系的方法，用于发现两国间潜在的间接创新合作机会。[方法/过程] 全球价值链上不同环节专利之间的引用关系中，蕴含着相互衔接、配套的间接合作关系，而不同环节的专利通常具有不同的功能，即IPC存在一定跨越度。因此，设计"专利引用跨越度"指标及算法，用于计量和筛选专利引用网络中"引用跨越度"达到预设阈值的专利引用关系，作为发现间接创新合作机会的基础数据。以新加坡在中国获得授权的发明专利为样本，基于专利引用跨越度计量并配合人工解读和识别，发现中新两国间一系列的间接创新合作机会。[结果/结论] 基于专利引用跨越度计量的两国间间接创新合作机会发现的方法，被实验检验为有效。  相似文献   

Multi-task learning based high-value patent and standard-essential patent identification model     

《Information processing & management》2023,60(3):103327

The high-value patent identification (HVPI) and the standard-essential patent identification (SEPI) are two important issues in the fields of intellectual property and the standardization, respectively. Almost all the HVPI and the SEPI are based on the single-task learning. In this paper, we unify the HVPI and the SEPI in a multi-task learning framework in consideration of the mutual reinforcement of the two tasks. In our model, we extract the patent structured features and embed the patent textual features using the pre-training model. Given these features, we explore a multi-task learning based identification model to identify the high-value patents and the standard-essential patents. We evaluate our model by comparing with two state-of-the-art models on the 5 balanced datasets and 2 imbalanced datasets. The results show our multi-task learning based model outperforms significantly these single-tasking learning based models in the measurements: precision, recall, F1 and accuracy. On the balanced datasets, the average increments of measurements are 1.3%, 1.29%, 1.28% and 1.28% respectively. On the imbalanced datasets, the average increments of measurements are 2.24%, 1.62%, 1.75% and 0.66% respectively.  相似文献

不同收入的城镇居民对体育消费结构和体育消费需求的影响*     

于〓乐  程〓蕾 《广州体育学院学报》2019,(5):26-30

采用问卷调查和数理统计方法，研究了不同收入的居民对体育消费结构和体育消费需求的影响。结果表明，随着居民收入的增加，各类体育消费都呈现上升趋势，实物型体育消费增长速度变慢，观赏型体育消费和健身型体育消费增长速度变快，当居民年收入在10万以上时，观赏型体育消费和健身型体育消费开始急剧增加。制约体育消费需求的主要因素是居民的收入、体育消费的价格、体育消费结构和居民的可支配时间。  相似文献   

Structural Analysis for Replicating Japanese Cultural Property Braids     

Masumi Tada  Kazuaki Yamashiro  Iwataro Oka  Akihiko Goto  Noriaki Kuwahara 《文物保护研究》2020,65(7):399-410

ABSTRACT

Historic Japanese textiles from over 1000 years ago generally show marked deterioration and only very rare examples show their original forms and much information about textile reproduction has been lost. The replication of textile braids lacks systematic methodology and is still being practiced by only few individual braiding experts. The recreation of original braids as close as possible to original braids is a part of Japan’s intangible cultural heritage. The aim of this study is to clarify the decision-making procedure through which the braiding experts can decipher the original braiding structures. As a preliminary study of this project, interviews of a braid researcher and a replicating expert, Makiko Tada were performed regarding her working practices. It is important to clarify the braiding parameters for structural analysis such as the number of transits and the balance of ridges, and it became clear that the orientation of multiple colored threads plays an important role. The expert’s replicate works were also analyzed using a text-mining statistical technique to clarify the relationship of braiding parameters. The relationship between each braiding parameter and production method such as loop manipulation and Taka-dai became clear. As a result, the process of deciphering the original braid structure has been compiled in simplified workflows, which could contribute to the standardization and improvement in efficiency of replication of cultural property braids.  相似文献   

一种基于图卷积自编码模型的多维度学科知识网络融合方法     

李慧  胡吉霞 《图书情报工作》2020,64(18):114-125

[目的/意义] 针对包含单一类型知识单元的知识网络难以全面反映学科知识结构的问题，提出一种从多维度进行知识网络结构融合的方法，为学科领域知识结构挖掘提供借鉴。[方法/过程] 利用LDA及TF-IDF方法抽取学科知识单元，然后运用语义相似度和关键词共现分析方法构建3个学科知识子网络：主题网络、关键词网络和实体网络，并采用空间节点传递对齐方法对齐子网络节点，接着设计基于图卷积操作的自编码模型对知识节点进行表示，最后通过计算余弦相似度重构学科知识网络。[结果/结论] 实验部分以人工智能领域为例，构建融合主题、关键词和实体的学科知识网络并展开分析，实验结果表明，本文所提方法能有效地揭示学科领域研究内容和知识结构，为学科知识发现与组织研究提供有益参考。  相似文献

北京冬奥会筹备对运动休闲基地建设的示范作用研究     

李杰桃 《广州体育学院学报》2020,(3):43-45

北京冬奥会雪上项目将在张家口市崇礼区进行，冬奥会筹备工作的重点也就集中在了这个过去名不见经传的小镇上了。虽然距冬奥会开幕还有近2年的时间，但崇礼区作为滑雪运动圣地已蜚声海内外，国外专业滑雪运动队将它作为训练基地外，国内业余滑雪运动者也从全国各地涌向这里。如今，张家口市整个经济被冬奥会激活了，其产业结构也已因崇礼区滑雪运动休闲基地实现了从农业经济向资源旅游经济的转型。虽然冬奥会筹备是国家级的大事，但张家口崇礼区的建设筹备仍然对全国休闲运动基地建设具有示范指导意义。  相似文献   

股权结构、研发投入与企业经营绩效关系研究     

谭庆  吴铖铖  吴自爱 《保定学院学报》2020,(2):46-51

以我国316家信息技术业上市公司2014—2018年面板数据作为研究对象,通过运用多元线性回归和调节效应检验研究研发投入与经营绩效的关系及股权结构在二者关系间的调节作用。研究结果表明:第一,研发投入与企业经营绩效正相关,且研发人员投入对企业经营绩效的影响高于研发资金投入;第二,股权集中度、股权制衡度均与企业经营绩效正相关。因此,信息技术企业在提高研发创新能力时不仅需要足够的资金保障,更需要充足的智力支持,且适度提高股权集中度、股权制衡度可在一定程度上提高企业经营绩效。  相似文献   

Mapping continuity and change in the intellectual structure of the knowledge base on problem-based learning, 1974–2019: A systematic review     

Philip Hallinger 《British Educational Research Journal》2020,46(6):1423-1444

Problem-based learning (PBL) emerged during the 1970s in response to demands for active learning methods capable of developing transferable knowledge and skills in the training of doctors. Over succeeding decades, PBL was gradually adopted in other fields of education. This systematic review aimed to identify key streams of theory and empirical research that have emerged over time in PBL research and practice. The review sourced 12,036 Scopus-indexed documents published between 1974 and 2019. Science mapping was used to reveal the ‘intellectual structure’ or key research themes that have evolved in this literature over the past 45 years. The science mapping tool used in this review was author co-citation analysis conducted in VOSviewer software. Author co-citation analysis identified three schools of thought that together describe the intellectual structure of the PBL knowledge base: Design of PBL Curriculum and Instruction; PBL Effectiveness; Theory and Practice in Active Learning. In addition to portraying the intellectual structure of the literature as a whole, the review also conducted longitudinal analyses aimed at highlighting structural changes in this field over time. These analyses found that although the size and impact of schools of thought associated with Design of PBL Curriculum and Instruction and PBL Effectiveness increased over time, they remained stable in terms of theoretical foci. However, the Active Learning school evolved from a small school of authors associated with Cognitive Learning Theories prior to 2000 into the largest school of thought during the most recent decades. These findings both reaffirm the theoretical underpinnings of the PBL knowledge base and highlight its increasing integration with other forms of active learning.  相似文献
