高校图书馆学习支持服务活动体系及其模型建构

[目的/意义] 总结高校图书馆学习支持服务活动体系并建构模型,以更好地理解高校图书馆学习支持服务的整体结构和运行机理。[方法/过程] 基于实际调研和主要职能总结出高校图书馆学习支持服务的基本形式和支撑条件。以活动为基本单位,分析学习支持服务活动的运行机理,进而尝试建构高校图书馆学习支持服务活动模型。[结果/结论] 资源服务形式和素质培育形式是高校图书馆学习支持服务的基本形式,空间、技术、人员是学习支持服务的3个支撑条件,应与基本形式相结合。两种基本形式与3个支撑条件的各种组合构成了高校图书馆学习支持服务的活动体系,需要基于活动的设计和组织进行深度融合。建构了一个高校图书馆学习支持服务活动的双螺旋模型,在机理上呈现出主体性的活动推动、非线性的逻辑递进、协同化的支持服务、共生式的融合发展等特征。     

News audience fragmentation in the Japanese Twittersphere

ABSTRACT

Although computational approaches to ideology-based audience fragmentation are promising, they are not without limitations. First, most existing studies have focused on the US, and the cross-national validity of their results has rarely been tested. Second, previous studies that rely solely on behavioral data from social media tend to make strong analytical assumptions such as that Twitter users prefer to follow media and politicians whose ideological positions are similar to their own, and that the ideologies of political elites can be extrapolated to infer the ideologies of ordinary users. We aim to address these limitations. First, we focus on Japan to test the generalizability of US findings in an Asian context. Second, we do not rely solely on behavioral measurement but combine survey and social media data to infer the ideologies of Twitter users. Results indicate that our classifier built based on these self-reported ideologies produces more valid estimates than naïve extrapolation from views of the elites. Based on these improved estimates of Twitter users’ ideologies, we demonstrate that the ideological distributions of those who follow major Japanese media accounts on Twitter largely overlap, suggesting an absence of ideology-based audience fragmentation.

Predicting citation counts based on deep neural network learning techniques

With the growing number of published scientific papers world-wide, the need to evaluation and quality assessment methods for research papers is increasing. Scientific fields such as scientometrics, informetrics, and bibliometrics establish quantified analysis methods and measurements for evaluating scientific papers. In this area, an important problem is to predict the future influence of a published paper. Particularly, early discrimination between influential papers and insignificant papers may find important applications. In this regard, one of the most important metrics is the number of citations to the paper, since this metric is widely utilized in the evaluation of scientific publications and moreover, it serves as the basis for many other metrics such as h-index. In this paper, we propose a novel method for predicting long-term citations of a paper based on the number of its citations in the first few years after publication. In order to train a citation count prediction model, we employed artificial neural network which is a powerful machine learning tool with recently growing applications in many domains including image and text processing. The empirical experiments show that our proposed method outperforms state-of-the-art methods with respect to the prediction accuracy in both yearly and total prediction of the number of citations.
