摘要:

通过研究和新的科学发现,世界的集体知识正在不断发展。客观地对研究机构对全球进步的影响进行排名变得越来越困难。然而,由于资金,政府支持,工作人员和学生的质量都反映了机构的预期质量,因此必须以透明和广泛接受的方式衡量联盟的评级。我们提出并研究了几种方法来排名隶属关系的基础上,他们接受的论文在未来的学术会议的数量。我们使用公开的数据集进行调查,例如Microsoft Academic Graph,这是一个包含有关学术论文的各种信息的异构图。我们分析了几个模型,从一个简单的基于概率的方法开始,然后逐渐扩展我们的训练数据集,设计更多的特征,并使用混合模型和梯度提升的决策树模型来改进我们的预测。

英文摘要:

The world's collective knowledge is evolving through research and new scientific discoveries. It is becoming increasingly difficult to objectively rank the impact research institutes have on global advancements. However, since the funding, governmental support, staff and students quality all mirror the projected quality of the institution, it becomes essential to measure the affiliation's rating in a transparent and widely accepted way. We propose and investigate several methods to rank affiliations based on the number of their accepted papers at future academic conferences. We carry out our investigation using publicly available datasets such as the Microsoft Academic Graph, a heterogeneous graph which contains various information about academic papers. We analyze several models, starting with a simple probabilities-based method and then gradually expand our training dataset, engineer many more features and use mixed models and gradient boosted decision trees models to improve our predictions.
