SIPR: Side-Information Pointwise Ranking Model for Scientifi...

2021中国智能自动化大会(CIAC2021)

作者： benzhi wang Feifei Kou Juping Du Mingying Xu Beijing Key Laboratory of Intelligent Telecommunication Software and Multimedia School of Computer ScienceBeijing University of Posts and Telecommunications

Learning to rank has been applied to many web searches, but it cannot be directly applied to retrieval scientific research projects. In scientific research project query, people are not only concerned about the name of the project, but also the digital information and sideinformation, such as duration, achievements, funding amount of this project. Howerver, the existing learning to rank methods ignore the side-information of scientific research projects. Therefore, we propose a Side-information Pointwise Ranking model(SIPR) for scientific research project query based on deep language model, click model and learning to rank. First, we use the deep language model to extract the semantic information of text, and design a relevance calculation model to extract features of side-information, then we merge the above two features. After that we use the click model to eliminate position bias, and get a ranking score through pointwise DNN. Finally, we can get the query results ordered by these scores. Experiments on real scientific research projects dataset demonstrate that our model can achieve better performance.

通过对平炉顶吹氧枪进行测定和实验研究,阐述了氧枪喷管中气体流动的基本规律,并从理论上导出了与拉伐尔喷管形式相同的直筒喷管流量计算公式,简化了直筒喷管的流量计算。直筒喷管流出的氧气射流中存在着强激波,使射流的滞止压力沿轴向衰减较快。为了减弱氧气射流中激波的强度,研制了一种加工简便的直筒-扩张型超音速喷管。实验研究证实,这种喷管和拉伐尔喷管的氧气射流的特性基本相同。文中介绍了这种喷管的性能和设计方法。
