| 1 | Study on Undertaking-starting of New Generation Migrant Workers显示文摘New generation migrant workers have become mainstay of China's migrant workers and also major builders of China's urbanization process. Compared with last generation migrant workers,new generation migrant workers have greater awareness of starting an undertaking. In the new trend,undertaking-starting is inevitable for new generation migrant workers. This study analyzed problems encountered by new generation migrant workers in the course of starting an undertaking. It reached conclusions that competent authorities should set up support mechanism in undertaking-starting training,undertaking-starting fund,service platform,and preferential policies,to encourage and support new generation migrant workers to start an undertaking. | Chuang LU Wanzhao LIU | 2014 | Asian Agricultural Research2014，6，3： | 0 |
| 2 | Application of Article - Level Metrics and comparison with Journal- Level Metrics in differentiated document recommendation: An empirical study in artificial intelligence field显示文摘The measurement indexes of literature include citation frequency,H index,etc.The evaluation of core joumals mainly relies on the indexes such as impact factor or comprehensive evaluation method.With the in-depth development of research,these indicators are not comprehensive and accurate for literature and jourmals.Therefore,according to various literature needs for different researchers,'core literature'in this study was divided into three types:classical,popular and frontier;and measurement system of document value was constructed with comprehensive use of entropy weight method and principal component analysis from the perspective of Article-Level Metrics.In the case study of artificial intelligence(AD),three types of document sets were acquired with the threshold value of specific indicators,and then measured by a combination of multi-index,achieving identification and recommendation of core documents for different research needs.At the same time,this paper further calculates the total score of the joumals according to the literature score,and finds that the journal distribution of different types of core literature is quite different.The difference between the ranking of joumal scores and the ranking of impact factor after literature classification is relatively large,but the ranking of jourmal normalized Eigenfactor and the ranking of impact factor are similar.These research directions,loading joumals,selected indicators,and temporal effects in three types of core documents were revealed in the study,which can provide a certain reference for promoting scientific research in AI and launching scientific research management services. | Feifei Wang Wanzhao Lu Yusi Hou | 2021 | Data Science and Informetrics2021，1，4： | 0 |
