A Cross-National Study of Computer News Sites: Global News,Local Sites

The Internet is not only an object of and a tool for study; it is also both simultaneously global and local. In order to address how global and how local it is, this study compares the news content of 1 week from four different computer news web sites in four different countries (using four different languages). These sites use the same code base and all strive to be the same in terms of computer culture. They are global in their reach and in the news they cover, yet they are all local in terms of language and geography. They are ideal locales to study how forces of the global and the local play out on the highly connected Internet, using Google language tools for translation. Findings were surprising in that they showed very little in terms of a pattern of any sort. This is similar to a 1953 UNESCO study of newspapers, but strange in that given the passing of 50 years and the connectedness of the Internet, greater overlap was expected. Link destinations for stories that were on more than one site were also examined, and the Japanese site had more in common with the American site while the two European sites were more alike in this lens. This is also surprising, given that an East/West split was expected. Little work in this specific area was found, and this study highlights some of the questions and methodological difficulties that need to be addressed.     

The Internet and the Demand for News

Looking Backward and Forward at the Internet

This article reviews accounts of the origins and growth of the global Internet with an interest in their implications for the future. Many accounts take overly restricted views of technical development. For instance, the Internet is often seen simply as the outgrowth of U.S. Defense Department work and popular enthusiasm. Recent interdisciplinary studies of technology present a more complex picture of how innovations are developed. They highlight technical alternatives, contributions of diverse groups, variety in meanings of technologies, and the overall surprising character of technology development. They suggest that the Internet has multiple origins and numerous particular reasons for its spread. Current discussions of the entry of Internet technologies into consumers' homes and the convergence among computing, media, and telecommunications enterprises represent examples of more complex accounts of technology development. Such accounts will likely provide more powerful bases for policy, management, and design.

[目的/意义]对社交媒体中热门新闻的及时识别,有助于加速正面资讯的投送或抑制负面资讯的扩散。当前,基于自然语言处理的传统识别方法正面临社交媒体新生态的挑战：大量新闻内容以图片、音视频形式存在,缺乏用于语义及情感分析的文本。[方法/过程]对此,本文首先将社交网络划分为众多社群,并按其层次结构组织为贝叶斯网络。接着,面向社群构建基于卷积神经网络的热门新闻识别模型,模型综合考虑新闻传播的宏观统计规律及微观传播过程,以提取社群内热门新闻传播的特征。最后,利用贝叶斯推理并结合局部性的模型识别结果进行全局性热度预测。[结果/结论]实验表明,本方法在语义缺失场景下可有效识别热门新闻,其准确度强于基于语义信息的机器学习方法,模型具有良好的时效性、可扩展性和适用性。该研究有助于社交媒体的监管机构及时识别出各类不含语义信息且迅速扩散的热点内容。     

News recommender systems – Survey and roads ahead

More and more people read the news online, e.g., by visiting the websites of their favorite newspapers or by navigating the sites of news aggregators. However, the abundance of news information that is published online every day through different channels can make it challenging for readers to locate the content they are interested in. The goal of News Recommender Systems (NRS) is to make reading suggestions to users in a personalized way. Due to their practical relevance, a variety of technical approaches to build such systems have been proposed over the last two decades. In this work, we review the state-of-the-art of designing and evaluating news recommender systems over the last ten years. One main goal of the work is to analyze which particular challenges of news recommendation (e.g., short item life times and recency aspects) have been well explored and which areas still require more work. Furthermore, in contrast to previous surveys, the paper specifically discusses methodological questions and today’s academic practice of evaluating and comparing different algorithmic news recommendation approaches based on accuracy measures.     

基于互联网传播文本的地区环境形象评价方法

An investigation of the levels of abstraction of tags across three resource genres

This study investigates how resource genres affect the specificity or level of abstraction of user-generated tags. This study found significant variations in frequency of assignment of superordinate, subordinate and basic level terms representing news, blog and ecommerce resource genres. Study observed users’ preferences to represent news and blog resources with basic or subordinate level tags and ecommerce resources with superordinate and basic level of tags. Study also observed multifaceted representation of resource genres, suggesting that use of genre tags is “situated” and grounded in language. This study suggests that representation of knowledge based on resource genres and levels of abstraction of user-generated tags may improve representation, organization, and findability of the resources in the distributed knowledge environments.     

Does the Great Firewall Really Isolate the Chinese? Integrating Access Blockage With Cultural Factors to Explain Web User Behavior

The dominant understanding of Internet censorship posits that blocking access to foreign-based websites creates isolated communities of Internet users. We question this discourse for its assumption that if given access people would use all websites. We develop a conceptual framework that integrates access blockage with social structures to explain Web users’ choices, and argue that users visit websites they find culturally proximate and that access blockage matters only when such sites are blocked. We examine the case of China, where online blockage is notoriously comprehensive, and compare Chinese Web usage patterns with those elsewhere. Analyzing audience traffic among the 1000 most visited websites, we find that websites cluster according to language and geography. Chinese websites constitute one cluster, which resembles other such geolinguistic clusters in terms of both its composition and its degree of isolation. Our sociological investigation reveals a greater role of cultural proximity than access blockage in explaining online behaviors.

Bridges Between Cultural and Digital Worlds in Revolutionary Egypt

Networks are both imagined and directly experienced. While most people have trouble concretely explaining what networks are and how they structure our world, very few doubt their prominence in an increasingly globalized world where information moves at a dizzying pace. Networks speak to the link between the local and global—linking an event in a small village in Tunisia to the evening news in London. Yet they bind peoples and ideas not only across distance, but also in proximity. How are such networks imagined by peoples across dimensions of class, religion, gender, and generation in the dynamic environment that is revolutionary Egypt today? This article presents initial findings from initial ethnographic and interview-focused fieldwork conducted with Egyptians across a range of demographics. It presents insights around how technological, institutional, and human networks coordinate to present convergent and divergent actions, insights that shape an ever-changing Egyptian political reality.

History and Habit in the Mobilization of ICT Resources

Evidence demonstrates that the digital divide is deepening despite strategies mobilized worldwide to reduce it. In disadvantaged communities, beyond training and infrastructural issues, there often lies a range of cultural and historically formed relationships that affect people's adoption of ICTs. This article presents an analysis of local resident's engagement with their council's pilot project to develop a computer facility in their community center. We ask, to what extent can people in poor urban communities, once trained, be expected to volunteer to work on furthering community education and development in ICTs in their local area? Findings indicate four patterns of individual engagement with the computer project: reflexive, utilitarian, distributive, and nonparticipatory. It is argued that local people engaged with the intervention in historically patterned and locally distinctive ways that served immediate personal and pragmatic ends. They did not adopt the long-term strategic goals of the council or university.     

Conceptualizing and Measuring the Social Uses of the Internet: The Case of Personal Web Sites

The researchers working on information society measures have recently started to consider how people use the Internet not only as a tool but also as a platform for social relations. As the ultimate objective of information society measures is to provide reliable guidelines for social policy, finding criteria for separating “positive” uses of Internet from “negative” ones is an important task. This article employs the concepts of communicative and strategic action as defined by Habermas for that purpose. A general conceptual typology of three communicative and three strategic social uses of Internet is offered, which can be applied to measure uses of any of the Internet's interactive services. A specific empirical application to social uses of personal web sites demonstrates that the deduced measurement instruments achieve satisfying levels of validity and reliability.
