基于特征表现的虚假评论人预测研究

[目的/意义]重点探讨基于特征表现的虚假评论人的预测,目的在于揭示真实网络环境中"网络水军"的特点和行为规律,构建一个简洁清晰、可解释的评论人身份预测模型,为深层次的评论挖掘研究奠定基础。[方法/过程]结合实证分析和机器学习技术,对目标网站"大众点评网"的内部评价机制进行探索,利用因子分析提炼评论人属性及行为表现特征,并在此基础上构建基于Logistic回归的预测模型。[结果/结论]对于目标网站,模型对虚假评论人的分类预测精度达到73.8%,AUC指标达到80.9%。而评论人的贡献度、活跃度以及文字素养被验证与其身份有统计意义上的显著关系,但评论人的层级、情绪以及评价偏差则对其身份预测的影响不显著。实验结论和经验分析基本保持一致,模型能够被合理解释。     

Intelligent system for diabetes prediction in patients with chronic pancreatitis

This paper presents the results of the JSM-method for automated support of scientific research (ASSR JSM-method) implemented in a computer intelligent system (IS-JSM), which predicts the development of diabetes in patients with chronic pancreatitis. For the first time the ASSR JSM-method is applied to a sequence of expanding databases of facts, which was used for the detection of empirical regularities (ERs), viz., preserved causes of the studied effect (development of diabetes in patients with chronic pancreatitis). To recognize ERs in the IS-JSM, we used an algebraic lattice of JSM-reasoning strategies (inductive inference rules). These results have an informative clinical interpretation and prove the usefulness of data mining using the IS-JSM, which can be used as a tool for evidence-based medicine.     

基于国际权威科学奖励的科学发现规律研究述评

科学奖励是有关科学共同体对特定科学发现成果的共识性学术认可评价,是反映科学发展重要突破、进展脉络和趋势的一扇窗口。为了厘清科学奖励相关研究的阶段特点、内容与规律、问题与趋向,本文综合利用定性和定量分析方法,从科学奖励的有关概念与理论基础出发,聚焦于科学奖励获得者（科学发现生产者）与获奖成果（科学发现本身）两大研究主题对象,由点至面,详细梳理相关研究的主要内容、特点与差异,尝试总结基于国际权威科学奖励的科学发现规律研究存在的不足与问题、未来研究的可能视角与趋向。

Characteristic scores and scales: A bibliometric analysis of subject characteristics based on long-term citation observation

In an earlier paper by Glänzel and Schubert [Glänzel, W., & Schubert, A. (1988a). Characteristic scores and scales in assessing citation impact. Journal of Information Science, 14(2), 123–127; Glänzel, W., & Schubert, A. (1988b). Theoretical and empirical studies of the tail of scientometric distributions. In L. Egghe, & R. Rousseau (Eds.), Informetrics: Vols. 87/88, (pp. 75–83). Elsevier Science Publisher B.V.], a method for classifying ranked observations into self-adjusting categories was developed. This parameter-free method, which was called method of characteristic scores and scales, is independent of any particular bibliometric law. The objective of the present study is twofold. In the theoretical part, the analysis of its properties for the general form of the Pareto distribution will be extended and deepened; in the empirical part the citation history of individual scientific disciplines will be studied. The chosen citation window of 21 years makes it possible to analyse dynamic aspects of the method, and proves sufficiently large to also obtain stable patterns for each of the disciplines. The theoretical findings are supplemented by regularities derived from the long-term observations.

A stochastic approach to the relation between the impact factor and the uncitedness factor

Empirical analysis of the relationship between the impact factor – as measured by the average number of citations – and the proportion of uncited material in a collection dates back at least to van Leeuwen and Moed (2005) where graphical presentations revealed striking patterns. Recently Hsu and Huang (2012) have proposed a simple functional relationship. Here it is shown that the general features of these observed regularities are predicted by a well-established informetric model which enables us to derive a theoretical van Leeuwen–Moed lower bound. We also question some of the arguments of Hsu and Huang (2012) and Egghe (2013) while various issues raised by Egghe, 2008, Egghe, 2013 are also addressed.

The evolution of the finding aid in the United States: from physical to digital document genre

In this article, we examine the American finding aid as a form of genre from both a cognitive and a sociological perspective and use this analysis to articulate some of the hidden or underlying regularities and assumptions of archives work. As finding aids increasingly are created and delivered digitally, we can anticipate tensions in the form and use of these genres giving rise to increased scrutiny of archival practices that in turn should cause us to explore the representation of the archives profession in a digital world. A particular focus of this article is to advance an argument that for too long, the actual consumption and use, that is, the reading of finding aids, has been ignored or overlooked. Yet, it is likely that only through understanding how people exploit and read these documents in real use can we improve their design. In so doing, we make a case for archival research to move further into the analysis of user behavior, information seeking, and contemporary information practices so as to improve and extend the appreciation of how archives contribute to the larger information field.

图书馆学研究范式的若干概念及应用探析

规范研究、经验研究、思辨研究、实证研究、定性研究与定量研究是常用的图书馆学研究范式。梳理这些研究范式的概念与相互之间的联系,有助于规范图书馆学研究方法,扩展图书馆学研究思路。目前我国图书馆学经验研究、规范研究、定性研究偏多,实证研究缺乏,定量研究往往被忽视。为此,图书馆学研究应坚持多种研究范式并存与互补应用,定量研究与定性研究相结合,实证研究与规范研究相结合,弘扬实证研究方法,从而促进图书馆学繁荣发展。
