同行评议是当前对科研项目水平进行科学评价的主要方式之一,然而评议过程中专家评审能力的差别将会对科研项目评审结果产生影响。为此,本文提出了一种基于PageRank算法的评审专家信誉度度量方法,该方法首先利用高斯分布函数计算评审专家的评审能力,然后利用PageRank迭代算法对评审专家的信誉度进行求解,最后通过引入时间因子对评审专家的信誉度进行度量。基于同行评议真实数据集上的实验结果验证了本文提出方法的有效性,该方法将为科研项目评审及专家遴选提供有益参考。 相似文献

Reviewer assignment is an important task in many research-related activities, such as conference organization and grant-proposal adjudication. The goal is to assign each submitted artifact to a set of reviewers who can thoroughly evaluate all aspects of the artifact’s content, while, at the same time, balancing the workload of the reviewers. In this paper, we focus on textual artifacts such as conference papers, where both (aspects of) the submitted papers and (expertise areas of) the reviewers can be described with terms and/or topics extracted from the text. We propose a method for automatically assigning a team of reviewers to each submitted paper, based on the clusters of the reviewers’ publications as latent research areas. Our method extends the definition of the relevance score between reviewers and papers using the latent research areas information to find a team of reviewers for each paper, such that each individual reviewer and the team as a whole cover as many paper aspects as possible. To solve the constrained problem where each reviewer has a limited reviewing capacity, we utilize a greedy algorithm that starts with a group of reviewers for each paper and iteratively evolves it to improve the coverage of the papers’ topics by the reviewers’ expertise. We experimentally demonstrate that our method outperforms state-of-the-art approaches w.r.t several standard quality measures. 相似文献

科研项目遴选制度的缺陷：证据及其解释 总被引：1，自引：0，他引：1
虽然科研项目遴选制度在科研资助过程中的作用十分显著。但是，科研项目遴选制度并非完美无缺的。案例研究表明，科研项目遴选制度存在三大缺陷，即同行评议的一致性程度不高，遴选结果具有一定的随机性，以及人情关系可能影响评议意见。这是因为，科研资源与科研成果的所有权并不属于评议专家，评议者与被评者之间存在信息不对称，科研项目遴选过程存在“交易收益”，而科研项目遴选制度还要受到遴选成本的约束。 相似文献

Automatic review assignment can significantly improve the productivity of many people such as conference organizers, journal editors and grant administrators. A general setup of the review assignment problem involves assigning a set of reviewers on a committee to a set of documents to be reviewed under the constraint of review quota so that the reviewers assigned to a document can collectively cover multiple topic aspects of the document. No previous work has addressed such a setup of committee review assignments while also considering matching multiple aspects of topics and expertise. In this paper, we tackle the problem of committee review assignment with multi-aspect expertise matching by casting it as an integer linear programming problem. The proposed algorithm can naturally accommodate any probabilistic or deterministic method for modeling multiple aspects to automate committee review assignments. Evaluation using a multi-aspect review assignment test set constructed using ACM SIGIR publications shows that the proposed algorithm is effective and efficient for committee review assignments based on multi-aspect expertise matching. 相似文献

TOPSIS法在科技人员业绩评价中的应用 总被引：10，自引：0，他引：10
目的：建立一个科学、客观、公正、可量化的卫生科技人员业绩评价方法。方法：针对多指标评价体系综合评价时广泛采用的线性加权求和法的弊端，首次在卫生科技人员科研业绩评价中引入理想状态空间的理论，利用逼近理想解的排序法(TOPSIS法)建立综合评价的数学模型。并在我校专业技术职务评聘中应用此模型予以检验。结果：TOPSIS法的量化评价结果与同行评议的实际结果具有较高的符合率。结论：本文所提出的综合评价方法更趋科学性、客观性、公正性和可行性，可为科学量化工作提供有益的参考。 相似文献

为了对学报审稿专家的审稿进行科学客观地评价,对审稿专家进行有效地激励,从审稿专家的"学术水平"、"审稿质量"、"审稿时效"、"职称"、"单位级别"这五个准则层面构建了审稿专家质量综合评价体系。对可以实现量化考核的指标进行量化评价,对无法量化考核的其他指标进行了相对客观合理的定性描述并设置分值,实现与量化评价的衔接。通过使用层次分析法(AHP法)确定审稿专家评价指标的权重,再使用模糊综合评判法(FCE法)来确定评价指标的隶属度,这样对综合两种方法得到的指标进行综合评判,使得对审稿专家的评价结果更加客观和准确。 相似文献

随着学术研究的日益规范化和复杂化，合作成为增加科研产出的主要途径。本文通过问卷收集了主要院校的科研评价制度，将其与三大经济管理类期刊的论文发表数据进行匹配，基于2000-2014年间部分高校调整第一作者制度的准自然实验，采用双重差分法（DID）的设计考察了科研制度对论文合作的影响。研究发现：（1）评职称认可非第一作者的制度能够使得论文合作的概率显著提高约33.5%，而评奖励承认非第一作者的制度没有显著影响；（2）在考虑了合作的异质性后，非第一作者制度主要促进了跨校合作，对院内合作和同校跨院合作的影响不明显；（3）作用机制分析表明，这种合作效应主要源自教师面临的晋升压力。本文的结论对于推动科研评价体系改革具有重要参考价值。 相似文献

Review helpfulness is attracting increasing attention of practitioners and academics. It helps in reducing risks and uncertainty faced by users in online shopping. This study examines uninvestigated variables by looking at not only the review characteristics but also important indicators of reviewers. Several significant review content and two reviewer variables are proposed and an effective review helpfulness prediction model is built using stochastic gradient boosting learning method. This study derived a mechanism to extract novel review content variables from review text. Six popular machine learning models and three real-life Amazon review data sets are used for analysis. Our results are robust to several product categories and along three Amazon review data sets. The results show that review content variables deliver the best performance as compared to the reviewer and state-of-the-art baseline as a standalone model. This study finds that reviewer helpfulness per day and syllables in review text strongly relates to review helpfulness. Moreover, the number of space, aux verb, drives words in review text and productivity score of a reviewer are also effective predictors of review helpfulness. The findings will help customers to write better reviews, help retailers to manage their websites intelligently and aid customers in their product purchasing decisions. 相似文献

Social commerce, an emerging phenomenon rooted in social media and Web 2.0 technologies, has attracted the attention of many researchers. The number of publications on social commerce has grown exponentially in the past 10 years. Now, social commerce has become a significant emerging research area. In this paper, we first define the boundary of social commerce research and then attempt to review the extant literature in this area comprehensively and systematically. Based on the definition, this study surveyed 1369 peer-reviewed academic publications in the social media, Web 2.0, and other related areas. Following the survey, 418 of the publications were identified as social commerce research. Then, latent semantic analysis (LSA), a text mining approach, was applied to summarize the current state of social commerce research. LSA results show that there are three major research themes in the current social commerce research: organization, advertisement, and word-of-mouth. Each theme discusses topics such as innovation, user-generated content, and reputation, among others. In addition, we identify some interesting trends. The first main trend is that innovation, corporate reputation, and user-generated content remain the major research topics, although they are experiencing a slight decline. The second main trend is that online reviews, trust, and e-word-of-mouth are attracting more attention from researchers. 相似文献
