[目的/意义] 创新性是对学术论文质量最基本的要求，是学术论文的灵魂，是学术论文评价的核心。知识元是学术论文基本组成单元。基于知识元理论和机器学习相关理论与算法，从学术论文内容层面研究计算机如何智能化地进行创新性评价及其实现过程与方法。[方法/过程] 首先，构建学术论文的研究问题、理论、方法、结论4个知识元本体，接着提出基于知识元的学术论文创新性判断模型。其次，根据学术论文研究特点，构建理论与方法机器分类模型及知识元的抽取规则与抽取方法，建立规则库和知识语料库。最后，基于语义相似度计算方法，根据判断规则和相关权重对学术论文4个维度的创新性进行评分。[结果/结论] 基于知识元抽取的学术论文创新性评分系统的实证结果表明，该智能化评价方法具有一定的可行性，可为学术论文内容创新性智能化评价系统的最终实现提供方法借鉴。  相似文献   

PCSI:一种单篇论文被引频次标准化方法     

伍军红  肖宏  任美亚  冯士雍  丁哲 《图书情报工作》2020,64(23):22-30

[目的/意义] 文章的被引频次一直是量化评价一篇论文学术影响力的重要指标。但在不同学科不同年份发表的论文会因该领域研究论文数、引用滞后等因素呈现较大的差异。因此在对比两篇论文时，难以简单依据被引频次的绝对值来评判论文影响力大小。为此，本文设计了一个新的可计算数学模型，使得每篇论文可以有一个标准化的指标，以便对不同学科不同年份发表的论文的学术影响力进行直接比较。[方法/过程] 通过分析2006、2017两年中国科技类学术期刊各学科论文的被引频次分布规律，采用同学科论文被引频次的分布形态最接近对数正态分布的先设条件，提出一种被引频次标准化指数——Paper Citation Standardized Index （简称PCSI，中文"论文引证标准化指数"）。最后以中国科协优秀科技期刊论文评选结果为例，将它们与论文所属学科全部论文进行实证对比研究。[结果/结论] 结果证明，PCSI对不同年份、不同学科论文的被引频次进行了标准化，反映了被引频次的线性差距，是一种较为理想的单篇论文学术影响力比较评价工具。  相似文献   

成果与局限:试论我国首次体育学术论争     

李凤梅 《武汉体育学院学报》2020,54(11):34-40

新中国成立初期体育学界的探索和体育事业的发展，为当代体育哲学社会科学发展提供了重要的经验启示和思想资源。出于复杂原因，当时被"双百"方针孕育而生的首次体育学术论争，鲜有人提及。在学界内外争鸣氛围的激励下，这次论争系统总结了当时体育发展中的基本问题，空前活跃了体育研究氛围，也促使篮球战术、体育内行与外行、武术渊源和发展等具体问题的讨论得以深入展开；而历史条件的特殊性和局限性，致使其偏离了体育场域且未能充分关注基本国情；从研究者的态度、论争者的遗憾和体育界的反思等层面，对我国首次体育学术论争及其深远影响进行研判。  相似文献

Neural embedding-based indices for semantic search     

Fatemeh Lashkari  Ebrahim Bagheri  Ali A. Ghorbani 《Information processing & management》2019,56(3):733-755

Traditional information retrieval techniques that primarily rely on keyword-based linking of the query and document spaces face challenges such as the vocabulary mismatch problem where relevant documents to a given query might not be retrieved simply due to the use of different terminology for describing the same concepts. As such, semantic search techniques aim to address such limitations of keyword-based retrieval models by incorporating semantic information from standard knowledge bases such as Freebase and DBpedia. The literature has already shown that while the sole consideration of semantic information might not lead to improved retrieval performance over keyword-based search, their consideration enables the retrieval of a set of relevant documents that cannot be retrieved by keyword-based methods. As such, building indices that store and provide access to semantic information during the retrieval process is important. While the process for building and querying keyword-based indices is quite well understood, the incorporation of semantic information within search indices is still an open challenge. Existing work have proposed to build one unified index encompassing both textual and semantic information or to build separate yet integrated indices for each information type but they face limitations such as increased query process time. In this paper, we propose to use neural embeddings-based representations of term, semantic entity, semantic type and documents within the same embedding space to facilitate the development of a unified search index that would consist of these four information types. We perform experiments on standard and widely used document collections including Clueweb09-B and Robust04 to evaluate our proposed indexing strategy from both effectiveness and efficiency perspectives. Based on our experiments, we find that when neural embeddings are used to build inverted indices; hence relaxing the requirement to explicitly observe the posting list key in the indexed document: (a) retrieval efficiency will increase compared to a standard inverted index, hence reduces the index size and query processing time, and (b) while retrieval efficiency, which is the main objective of an efficient indexing mechanism improves using our proposed method, retrieval effectiveness also retains competitive performance compared to the baseline in terms of retrieving a reasonable number of relevant documents from the indexed corpus.  相似文献

梁金辉  胡智勇  胡德刚 《首都体育学院学报》2020,(3):233-240

借鉴ACSI顾客满意度测评指数模型,结合中国群众性马拉松赛事的特点,运用探索性因子分析法建立中国马拉松赛事参赛者满意度测评指标体系,基于此,构建中国马拉松赛事参赛者满意度测评指数模型。研究发现:中国马拉松赛事参赛者满意度测评指数模型的指标包括参赛者期望、硬服务质量感知、软服务质量感知、感知价值、参赛者满意度、参赛者抱怨、参赛者忠诚度7个因素。就各个自变量对中国马拉松赛事参赛者满意度的影响路径来看,参赛者对服务的预期通过对软服务质量感知、硬服务质量感知间接正向影响中国马拉松赛事参赛者满意度;参赛者的服务质量感知既直接又间接地正向影响参赛者的满意度,参赛者的软服务质量感知通过硬服务质量感知和感知价值间接正向影响参赛者的满意度,参赛者的硬服务质量感知通过感知价值间接正向影响参赛者的满意度。就各个自变量对中国马拉松赛事参赛者满意度的影响程度而言,参赛者的软服务质量感知对其满意度影响最大,其次依次为硬服务质量感知、服务期望和感知价值。  相似文献   

Ebooks in Academic Libraries     

Brad Vogus 《Public Services Quarterly》2020,16(3):182-185

Abstract

The number of ebooks continues to grow in academic libraries. Ebooks have many advantages that make them attractive as a library resource. However, ebooks also have restrictions. These include use and sharing restrictions, license restrictions, and technological barriers. Some students also prefer print books for specific tasks. The following articles examine many aspects of ebooks in academic libraries, including student preference, overall ebook use, and the advantages and disadvantages of various ebook acquisition models.  相似文献   

Adaptation and evaluation of a learning analytics dashboard to improve academic support at three Latin American universities     

Julio Guerra  Margarita Ortiz-Rojas  Miguel Angel Zúñiga-Prieto  Eliana Scheihing  Alberto Jiménez  Tom Broos  Tinne De Laet  Katrien Verbert 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(4):973-1001

Despite the success of academic advising dashboards in several higher educational institutions (HEI), these dashboards are still under-explored in Latin American HEI's. To close this gap, three different Latin American universities adapted an existing advising dashboard, originally deployed at the KU Leuven to their own context. In all three cases, the context was the main ruling factor to these adaptations. In this paper, we describe these adaptions using a framework that focuses on four different elements of the context: Objectives, Stakeholders, Key moment and Interactions. Evaluation of the adapted dashboards in the three different Latin American universities is conducted through pilots. This evaluation shows the value of the dashboard approach in different contexts in terms of satisfaction, usefulness and impact in academic decision-making and advising tasks. The main contribution of this paper is the systematic reporting of the adaptations to an academic advising dashboard and showing the value of an academic advising dashboard on academic decision-making and advising tasks.  相似文献
