The field of social computing emerged more than ten years ago. During the last decade, researchers from a variety of disciplines
have been closely collaborating to boost the growth of social computing research. This paper aims at identifying key researchers
and institutions, and examining the collaboration patterns in the field. We employ co-authorship network analysis at different
levels to study the bibliographic information of 6 543 publications in social computing from 1998 to 2011. This paper gives
a snapshot of the current research in social computing and can provide an initial guidance to new researchers in social computing. 相似文献
Monthly streamflow forecasting is vital for managing water resources. Recently, numerous studies have explored and evidenced the potential of artificial intelligence (AI) models in hydrological forecasting. In this study, the feasibility of the convolutional neural network (CNN), a deep learning method, is explored for monthly streamflow forecasting. CNN can automatically extract critical features from numerous inputs with its convolution–pooling mechanism, which is a distinct advantage compared with other AI models. Hydrological and large-scale atmospheric circulation variables, including rainfall, streamflow, and atmospheric circulation factors are used to establish models and forecast streamflow for Huanren Reservoir and Xiangjiaba Hydropower Station, China. The artificial neural network (ANN) and extreme learning machine (ELM) with inputs identified based on cross-correlation and mutual information analyses are established for comparative analyses. The performances of these models are assessed with several statistical metrics and graphical evaluation methods. The results show that CNN outperforms ANN and ELM in all statistical measures. Moreover, CNN shows better stability in forecasting accuracy.
