Web Content Analysis Web Content Analysis Workshop in Advanced Techniques for Political Communication Research: Web Content Analysis Session Professor Rachel Gibson, University of Manchester Aims of the Session • Defining and understanding the Web as on object of study & challenges to analysing web content • Defining the shift from Web 1.0 to Web 2.0 or ‘social media’ • Approaches to analysing web content, particularly in relation to election campaign research and party homepages. • Beyond websites? Examples of how web 2.0 campaigns are being studied – key research questions and methodologies. The Web as an object of study • Inter-linkage • Non-linearity • Interactivity • Multi-media • Global reach • Ephemerality Mitra, A and Cohen, E. ‘Analyzing the Web: Directions and Challenges’ in Jones, S. (ed) Doing Internet Research 1999 Sage From Web 1.0 to Web 2.0 Tim Berners-Lee “Web 1.0 was all about connecting people. It was an interactive space, and I think Web 2.0 is of course a piece of jargon, nobody even knows what it means. If Web 2.0 for you is blogs and wikis, then that is people to people. But that was what the Web was supposed to be all along. And in fact you know, this ‘Web 2.0’, it means using the standards which have been produced by all these people working on Web 1.0,” (from Anderson, 2007: 5) Web 1.0 The “read only” web Web 2.0 – ‘What is Web 2.0’ Tim O’Reilly (2005) “The “read/write” web Web 2.0 • Technological definition – Web as platform, supplanting desktop pc – Inter-operability , through browser access a wide range of programmes that fulfil a variety of online tasks – i.e. manage a home page, communicate with friends, share/publish pictures, receive news. • Social understanding – Web 2.0 is based around social networking activities – relies on and built through ‘social or participatory’ software. – Users create, distribute, value-add to online content through blogs, facebook profiles, online video, wikis, tagging tools. ‘Produsers’ Bruns (2007) or ‘Prosumers’ – distinction between producers and users/consumers of content disappears. – Hallmark of these applications is the way in which they devolve creative and classificatory power to ‘ordinary’ users. Web 1.0 & Web 2.0 applications ––‘social‘social media’ Web 1.0 • Websites • Email • Discussion forums/chat room/IM Web 2.0 or ‘social media’ • Blogs • Social Network Sites (Facebook) • Online Video sharing/posting (YouTube) • Online Photo sharing/posting (Flickr) • Microblogging sites (Twitter) @, #, RT • Online Link sharing/posting (Del.icio.us, Digg) Methodologies used for analysing online campaigns (supply(supply--side)side) Adapted from offline - `digitized methods` (Rodgers, 2010) Web 1.0 • Online interviews, elite surveys • Online discourse analysis • Online content/feature analysis – ‘Classic ‘ or offline approaches – ‘Web specific – mixed mode Online specific - ‘digital methods’ Web 2.0 • Hyperlinking and webspheres – Voson, Issue Crawler, SocScibotOnline, NodeXL, • Blog analysis toolkits and search engines –Technorati .

Unit of analysis is the web network rather than individual sites. • Thematic set of websites are identified, ‘captured’/archived over time and the linkage patterns explored as well as content. – Method pioneered by Schneider and Foot (2004) ‘Web Sphere analysis’. – Define a Web Sphere as a ‘hyperlinked set of dynamically defined digital resources spanning multiple Web sites and deemed relevant to related to a central theme or ‘object’.’ The borders of the sphere are defined relationship to central theme/object and a given time period. See Library of Congress, Internet Archive http://www.archive.org/index.php & WebArchivist.org http://webarchivist.org/ Hyperlink analysis More sophisticated/automated methods have developed for academic research since around 2003. – Adaptations of search engine technology – most simple form of online link analysis. – Hindman et al.

Scholar in Education, University of Kerala Email: [email protected] Abstract Our goal for this paper discusses the main research ethical concerns that arise in internet research and reviews existing research ethical guidance in relation to its application for educating digital citizens. In recent years we have witnessed a revolution in Information and Communication Technologies (ICTs) that has transformed every field of knowledge. Education has not remained detached from this revolution. Ethical questions in relation to technology encompass a wide range of topics, including privacy, neutrality, the digital divide, cybercrime, and transparency. In a growing digital society, digital citizens recognize and value the rights, responsibilities and opportunities of living, learning and working in an interconnected digital world, and they engage in safe, legal and ethical behaviors. Too often we see technology users misuse and abuse technology because they are unaware of

  • Methodologies for Crawler Based Web Surveys
    Mike Thelwall Page 1 of 19 Methodologies for Crawler Based Web Surveys Mike Thelwall1 School of Computing, University of Wolverhampton, Wulfruna Street, Wolverhampton WV1 1SB, UK [email protected] Abstract There have been many attempts to study the content of the web, either through human or automatic agents. Five different previously used web survey methodologies are described and analysed, each justifiable in its own right, but a simple experiment is presented that demonstrates concrete differences between them. The concept of crawling the web also bears further inspection, including the scope of the pages to crawl, the method used to access and index each page, and the algorithm for the identification of duplicate pages. The issues involved here will be well-known to many computer scientists but, with the increasing use of crawlers and search engines in other disciplines, they now require a public discussion in the wider research community. This paper concludes that any scientific attempt to crawl the web must make available the parameters under which it is operating so that researchers can, in principle, replicate experiments or be aware of and take into account differences between methodologies. A new hybrid random page selection methodology is also introduced. Keywords Web surveys, search engine, indexing, random walks 1 Introduction The current importance of the web has spawned many attempts to analyse sets of web pages in order to derive general conclusions about its properties and patterns of use (Crowston and Williams, 1997; Hooi-Im et al, 1998; Ingwerson, 1998; Lawrence and Giles, 1998a; Miller and Mather, 1998; Henzinger et al., 1999; Koehler, 1999; Lawrence and Giles, 1999a; Smith, 1999; Snyder and Rosenbaum, 1999; Henzinger et al., 2000; Thelwall, 2000a; Thelwall, 2000b; Thelwall, 2000d).

  • A History of Social Media
    2 A HISTORY OF SOCIAL MEDIA 02_KOZINETS_3E_CH_02.indd 33 25/09/2019 4:32:13 PM CHAPTER OVERVIEW This chapter and the next will explore the history of social media and cultural approaches to its study. For our purposes, the history of social media can be split into three rough-hewn temporal divisions or ages: the Age of Electronic Communications (late 1960s to early 1990s), the Age of Virtual Community (early 1990s to early 2000s), and the Age of Social Media (early 2000s to date). This chapter examines the first two ages. Beginning with the Arpanet and the early years of (mostly corpo- rate) networked communications, our history takes us into the world of private American online services such as CompuServe, Prodigy, and GEnie that rose to prominence in the 1980s. We also explore the internationalization of online services that happened with the publicly- owned European organizations such as Minitel in France. From there, we can see how the growth and richness of participation on the Usenet system helped inspire the work of early ethnographers of the Internet. As well, the Bulletin Board System was another popular and similar form of connection that proved amenable to an ethnographic approach. The research intensified and developed through the 1990s as the next age, the Age of Virtual Community, advanced. Corporate and news sites like Amazon, Netflix, TripAdvisor, and Salon.com all became recogniz- able hosts for peer-to-peer contact and conversation. In business and academia, a growing emphasis on ‘community’ began to hold sway, with the conception of ‘virtual community’ crystallizing the tendency.

  • Characterizing Search-Engine Traffic to Internet Research Agency Web Properties
    Characterizing Search-Engine Traffic to Internet Research Agency Web Properties Alexander Spangher Gireeja Ranade Besmira Nushi Information Sciences Institute, University of California, Berkeley and Microsoft Research University of Southern California Microsoft Research Adam Fourney Eric Horvitz Microsoft Research Microsoft Research ABSTRACT The Russia-based Internet Research Agency (IRA) carried out a broad information campaign in the U.S. before and after the 2016 presidential election. The organization created an expansive set of internet properties: web domains, Facebook pages, and Twitter bots, which received traffic via purchased Facebook ads, tweets, and search engines indexing their domains. In this paper, we focus on IRA activities that received exposure through search engines, by joining data from Facebook and Twitter with logs from the Internet Explorer 11 and Edge browsers and the Bing.com search engine. We find that a substantial volume of Russian content was apolit- ical and emotionally-neutral in nature. Our observations demon- strate that such content gave IRA web-properties considerable ex- posure through search-engines and brought readers to websites hosting inflammatory content and engagement hooks. Our findings show that, like social media, web search also directed traffic to IRA Figure 1: IRA campaign structure.

  • Evaluating Internet Research Sources
    Evaluating Internet Research Sources By Robert Harris Version Date: June 15, 2007 Introduction: The Diversity of Information Information is a Think about the magazine section in your local grocery store. If you reach out Commodity with your eyes closed and grab the first magazine you touch, you are about as Available in likely to get a supermarket tabloid as you are a respected journal (actually more Many Flavors likely, since many respected journals don't fare well in grocery stores). Now imagine that your grocer is so accommodating that he lets anyone in town print up a magazine and put it in the magazine section. Now if you reach out blindly, you might get the Elvis Lives with Aliens Gazette just as easily as Atlantic Monthly or Time. Welcome to the Internet. As I hope my analogy makes clear, there is an extremely wide variety of material on the Internet ranging in its accuracy, reliability, and value. Unlike most traditional information media (books, magazines, organizational documents), no one has to approve the content before it is made public. It's your job as a searcher, then, to evaluate what you locate in order to determine whether it suits your needs. Information Information is everywhere on the Internet, existing in large quantities and Exists on a continuously being created and revised. This information exists in a large Continuum of variety of kinds (facts, opinions, stories, interpretations, statistics) and is Reliability and created for many purposes (to inform, to persuade, to sell, to present a Quality viewpoint, and to create or change an attitude or belief).

Smedley PhD a, Neil S. Coulson PhD a a Division of Rehabilitation and Ageing, Queen’s Medical Centre, Nottingham, NG7 2UH Address for correspondence: Professor Neil S. Coulson Division of Rehabilitation & Ageing, School of Medicine Queen's Medical Centre Nottingham NG7 2UH UK +44 115 846 6642 1 Abstract As the number of online support forums continues to grow and the amount of user-generated content increases, analysing forum messages can provide researchers and others working in health-related fields with important new insights into the needs, opinions and experiences of individuals who use them. There has been a lack of guidance regarding how to make the best use of user-generated content within forums as a data source in research studies, so this paper explains the practical, ethical and methodological issues associated with this type of research. It describes the benefits of forum research, the organisational structure of forums, how forums are selected for research, approaches to sampling, preparing data for analysis, and methods of analysis that can be used. The decisions that researchers need to make during each stage of the research process are explained, describing the options available and the ethical dilemmas that need to be considered to successfully develop, carry out and complete a research project. Keywords: Online support communities; Forum; Sampling typology; Research methods; Ethics. About the authors: Richard M.

Sharma total data available, only 2-4% of data found is structured, Abstract: World Wide Web (WWW) is a massive resource of 16% data is semi-structured and more than 80% data is information that contains data in zeta bytes. Large number of unmanaged. Accessing such unmanaged data in minimum users surfing Internet for various purposes need a quick response time, using least number of resources is the most challenging from web. Search engines are preferable, easily available and task for the search engine [36]. A Web crawler or Web robot reliable source to retrieve data very rapidly with minimum is an essential component that automatically traverses the web resources. Search engine uses Web Crawler to search abundant data from web. It is a program that automatically passes through and searches links related to the user’s query [38]. It is a hypertext structure of the web and access webpage and hyperlink resource discovery and retrieval tool for search engines within it. Web crawling is a technique that focuses on obtaining [3,32]. Web Crawlers use various methods to traverse data relevant and fruitful links. To make the traversing accurate and from distributed and diversified websites. Web Crawling is productive, a properly designed web crawling algorithm is the technique to explore web applications automatically, required. Web crawler and crawling techniques are kept secret as browse hyperlinks, create index and store them for future use.

We studied Yahoo! search activity related to the 23 most common cancers in the United States. Objective: The objective was to test three potential correlates of Yahoo! cancer search activityÐestimated cancer incidence, estimated cancer mortality, and the volume of cancer news coverageÐand to study the periodicity of and peaks in Yahoo! cancer search activity. Methods: Yahoo! cancer search activity was obtained from a proprietary database called the Yahoo! Buzz Index. The American Cancer Society©s estimates of cancer incidence and mortality were used. News reports associated with specific cancer types were identified using the LexisNexis ªUS Newsº database, which includes more than 400 national and regional newspapers and a variety of newswire services. Results: The Yahoo! search activity associated with specific cancers correlated with their estimated incidence (Spearman rank correlation, ρ = 0.50, P = .015), estimated mortality (ρ = 0.66, P = .001), and volume of related news coverage (ρ = 0.88, P < .001).

Markham 9 10 11 12 13 14 Qualitative studies of the Internet are quite diverse. In the early 1990s, Julian 15 Dibbell published an ethnographically informed account and analysis of 16 a rape in cyberspace (1993). In a popular chatroom space of an online com- 17 munity, one member utilized a program that controlled the text-based actions 18 of two females present in the room. He then proceeded to write acts of violation 19 involving these women, while they were powerless to do anything except 20 turn off their computers, but their online characters continued to be violated 21 online in front of many other people. The event had serious repercussions 22 for the women violated and the community in general. 23 In the mid-1990s, Witmer and Katzman (1998) studied computer-mediated 24 communication (CMC) users and the ways they compensated effectively for 25 the absence of non-verbal and para-linguistic elements of conversation. Using 26 emoticons, users convey humor, irony, and other emotions, supplementing 27 the content of the message to enhance interpersonal connectedness. 28 In the late 1990s, Norwegian scholar Anne Ryen utilized the capacity of 29 the Internet to conduct a long-term and long-distance case study of an Asian 30 businessman in Tanzania. While she began by simply using the Internet as 31 a tool for extending her reach, Ryen ended up also examining how the Internet 32 influenced her personal and professional relationship with the participant 33 (2002).

  • What Is Internet? Ans: Internet Is an Interconnection of Several Thousands of Computers of Different Types Belonging to the Various Networks All Over the World
    What is internet? Ans: Internet is an interconnection of several thousands of computers of different types belonging to the various networks all over the world. Brief History of Internet In 1960s, the DOD of US started a project of network to share data and information. This network was called ARPA (Advanced Research Projects Agency) –ARPANET ARPANET helped in the development of new protocol called TCP/IP. Goal of this project was to create a large computer network with multiple paths using telephone lines to share resources and exchange data. In mid 1980s, another federal agency NSF joined ARPANET after DOD dropped its funding. Linked five regional areas with supercomputers to provide network facilities. Created new, higher capacity network called NSFnet. Allowed universities and research agencies to link up with its supercomputers. The link between ARPANET, NSFnet and other network was called Internet. Original ARPANET was shut down in 1990 and NSFnet was also discontinued in 1995. After the development of WWW in 1990s, the internet really became popular. Who controls the Internet? Ans: Different organization like ISOC (Internet Society), W3C (World Wide Web Consortium), IAB (Internet Architecture Board), IEFT (Internet Engineering Task Force), IRTF (Internet Research Task Force), IESG (Internet Engineering Steering Group) and INIC (Internet Network information Centre) gives directive and guideline for the proper use of internet. Why is internet called ‘network of networks’? Ans: The internet is called ‘network of networks’ because all the smaller networks of organizations are linked together into the one giant network called the internet. Which communication protocol is used by the internet? Ans: TCP/IP is the communication protocol used by the internet.
