应用关键动词抽取生物医学实体间语义关系研究综述

对利用关键动词(即语义关系动词)进行关系抽取的研究进行回顾,并对生物医学语义关系抽取的常用方法进行详细介绍。认为目前关系抽取研究中所利用的关键动词主要是人工选取的,涉及的主观因素较多,影响关键动词选取的客观性、准确性和全面性。因此,如何自动化地找到这些动词可能会成为今后关系挖掘的一项关键任务。     

学术文本中细粒度知识实体的关联分析

考察特定领域文本中蕴含的细粒度知识实体的使用情况,对知识实体的评估和选择具有重要意义。学术文本中的细粒度知识实体通常具有多个类型、多种关联关系,挖掘知识实体的同质与异质关联关系,有助于深入了解特定领域知识实体的实际使用情况。目前相关研究大多针对学术文本中单一知识实体的抽取和评估,缺乏对知识实体间关系的关注,在一定程度上限制了基于实体抽取进行知识发现的能力。文章以自然语言处理领域为例,对学术论文全文中的细粒度知识实体关联数据进行挖掘,并通过可视化方式揭示关联数据中蕴含的信息。主要是选取全国计算语言学会议2009-2018年间收录的中文论文为原始语料,人工标注论文中使用的知识实体,并针对NLP特点将其细分为“指标实体”“工具实体”“资源实体”“方法实体”4种类型;结合关联规则挖掘算法Apriori和复杂网络分析软件构建知识实体关联网络,揭示该领域常用的知识实体,以及这些知识实体的使用相关性。

Becoming Extra-Textual: Celebrity Discourse and Paul Robeson's Political Transformation

During the 1930s, news media constructed celebrities as individuals whose public lives naturally reflected (or expressed) their private lives. Paul Robeson, however, offered an intriguing challenge to such seamlessness, foreshadowing contemporary evocations of celebrity that highlight the fabricated nature of public personas. I posit that during the 1930s, the discursive formations of scandal and movie stardom challenged celebrity seamlessness by constructing Paul Robeson as a site of extra-textuality: Paul Robeson “the artist” became detached from Paul Robeson “the man.” Although mired in essentialism, Robeson's extra-textuality was crucial to his activism, for it ultimately created the space from which he voiced his most impassioned political polemics. Thus both regressive and liberatory, the discourses of scandal and movie stardom mediated Paul Robeson's transition from spiritual-singing aesthete to outspoken political activist.     

Naming Neda: Digital Discourse and the Rhetorics of Association

This article analyzes several online discourses centering on the death of Neda Agha Soltan, a young Iranian shot and killed during Iran's post-election protests in the summer of 2009. Hours after the tragic event, cell phone footage of Agha Soltan dying on camera was posted online by an anonymous citizen-journalist. Immediately, media users began juxtaposing images sampled from the footage with words, texts, photographs, drawings, and music. All sorts of competing and complimentary discourses emerged as media makers attempted to define the significance of the life and death of a young woman who became known to millions as simply, Neda.     

上海银行公会与1927年的政局

上海资本家与南京国民政府的关系早已引起国内外学者的关注,并有一些相关研究成果问世。综观已有成果,或由于资料限制或由于研究主体不同,尚不能使我们对南京国民政府建立前后上海金融界给予蒋介石财政支持的过程有系统的认识,也不能明了它对同时期其它政治集团的态度。笔者在阅读当时上海金融界的同业组织之一—上海银行公会(以下简称银行公会)的档案时,在会员会议录和来往函电中发现他们为筹款问题进行的反复交涉,以及他们对不同政治集团取舍的原因和表现,其中还包括领导层人员的多重身份对公会决议的影响。这些资料对于深入认识上海金融…     

Online Political Discourse: Exploring Differences in Effects of Civil and Uncivil Disagreement in News Website Comments

An experiment (N = 272) demonstrated that disagreement—either civil or uncivil—may have a chilling effect on the public discourse vital to a deliberative democracy. Both forms of disagreement—in comments posted on a news story about abortion—caused negative emotion and aggressive intentions. However, only uncivil disagreement led people to respond back uncivilly and indirectly led to greater intention to participate politically, if it aroused aggressive feelings. Findings support extending face and politeness theories to the computer-mediated space of online commenting. Results are discussed in relation to the impact on the public discourse.     

RDA的实体及关系解析

FRBR的实体-关系模型是RDA编制的结构基础,这种概念完全不同于AACR2的理念,同时它也是理解RDA的难点论文主要针对RDA中的实体、实体中的元素、实体之间的关系进行了分析,并利用图表进行详细的说明.结论是：RDA对文献描述的四个层次包括作品、内容表达、具体表现、单件,可以对书目信息进行深度揭示,四个层次之间也存在比较复杂的关系.

Using Text Mining to Compare Online Pro- and Anti-Vaccine Headlines: Word Usage,Sentiments, and Online Popularity

This study aims to explore differences between health misinformation and true information by comparing word usage, sentiments, and online popularity between pro- and anti-vaccine headlines (PVHs and AVHs). Text mining and sentiment analysis showed that AVHs were more likely to use negative sentiment words and trust-related words. PVHs were more likely to use words related to positive sentiments. Anti-vaccine messages (AVMs) were more popular online than pro-vaccine messages (PVMs). AVMs’ online popularity was not related to its emotion words usage. Among PVMs, those with more positive sentiment words were more likely to be shared, commented on, and reacted to online. Wordclouds and word networks were created to visualize the word usage and clustering. Future directions regarding message design and automatic detection and analysis techniques are provided.     

Internet Resources for Politics,Political Science,and Political Scientists

Summary

A typology of information needs for political science allows academic librarians to match local and Internet resources with materials relevant to public users, non-major undergraduates, political science majors, graduate students, and professional political scientists. Recognizing public and non-specialist users, we may distinguish needs for information about politics from that which is specifically political science information. Second, the needs of majors, graduate students, and political science professionals often fall within the bounds created by the discipline's generally recognized subfields. Finally, as academics, graduate students and professionals have functional needs for information that helps them teach, publish, and participate in professional affairs. Because the number of potentially relevant topics is singularly broad and the literature of the discipline spans two and a half millennia, this article emphasizes gateway or directory Web sites appropriate to each type of information need.

Political Discussion,Political News,and Internet Use: Factors of Media Trust in South Korea

This study examines political and communicative factors predicting trust in mainstream newspapers and television by analyzing a set of survey data collected in South Korea. The results show that supporters of the opposition party are less likely to trust the mainstream news media than supporters of the ruling party. Daily Internet use negatively predicted trust in media only for nonpartisans. However, for supporters of the opposition party, daily Internet use moderated the interaction effect between political discussion and exposure to political news on trust in media.     

话语事件:话语表征及其社会巫术的争夺

本文试图提出一个新的概念:话语事件。本文首先廓清了这一概念与其他概念之间的区别,界定了它的内涵,并对其进行了分类:道德抵制型话语事件、权益抵制型话语事件和国族抵制型话语事件。其次分析了它的两大特点:一是话语事件是对话语表征及其社会巫术效果的争夺;二是话语事件脚本的认知震撼或道德震撼特性及其三种基本模式。最后重点阐述权益抵制型话语事件具有逼迫真相出场的功效,是公众对话语主体的谨慎抵制。     

Playing With Politics: Online Political Parody,Affinity for Political Humor,Anxiety Reduction,and Implications for Political Efficacy

The current study examines the relationships between exposure to partisan political parody, affinity for political humor given a desire to reduce anxiety, and internal political efficacy. Analyzing data from a spring 2013 experiment (N = 269), the results suggest that prior media exposure, an affinity for political humor given the desire to reduce anxiety, and a preference for humor that attacks the opposition are significant predictors of political efficacy. In addition, a three-way interaction between partisan identification, humor type, and affinity for political humor (AFPH)–anxiety relative to the dependent variable of internal political efficacy was significant. In particular, high AFPH–anxiety Republicans who viewed Democrat-directed humor were more likely to feel politically efficacious. The significance of the findings is discussed along with suggestions for potential theoretical mechanisms that can guide future academic research on the democratic impacts of politically entertaining media.
