Image description has been a recurrent topic on web accessibility over the years. With the increased use of social networks, this discussion is even more relevant. Social networks are responsible for a considerable part of the images available on the web. In this context, users are not only consuming visual content but also creating it. Due to this shared responsibility of providing accessible content, major platforms must go beyond accessible interfaces. Additional resources must also be available to support users in creating accessible content. Although many of today's services already support accessible media content authoring, current efforts still fail to properly integrate and guide their users through the authoring process. One of the consequences is that many users are still unaware of what an image description is, how to provide it, and why it is necessary. We present SONAAR, a project that aims to improve the accessibility of user-generated content on social networks. Our approach is to support the authoring and consumption of accessible social media content. Our prototypes currently focus on Twitter and Facebook and are available as an Android application and as a Chrome extension.

In this chapter the authors discuss and informal learning settings such as fan fiction sites and their relations to teaching and learning within formal learning settings. Young people today spend a lot of time with social media built on user generated content. These media are often characterized by participatory culture which offers a good environment for developing skills and identity work. In this chapter the authors problematize fan fiction sites as informal learning settings where the possibilities to learn are powerful and significant. They also discuss the learning processes connected to the development of literacies. Here the rhetoric principle of “imitatio” plays a vital part as well as the co-production of texts on the sites, strongly supported by the beta reader and the power of positive feedback. They also display that some fans, through the online publication of fan fiction, are able to develop their craft in a way which previously have been impossible.

In an age of user-generated content, multimedia sharing sites, and customized news aggregators, an assortment of Internet-based social interaction technologies transforms the Web and its users. A quintessential embodiment of social interaction technologies, blogs are widely used by people across diverse geographies to locate information, create and share content, initiate conversations, and collaborate and interact with others in various settings. This chapter surveys the global blogosphere landscape for the latest trends and developments in order to evaluate the overall direction that blogging might take in the future. The author posits that network-based peer production and social media convergence are the driving forces behind the current transformation of blogs. The participatory and inclusive nature of social interaction technologies makes blogging a medium of choice for disseminating user-driven content and particularly suitable for bottom-up grassroots initiatives, creativity, and innovation.

On the day that the June 2006 issue of Wired magazine was released, the publication’s technology director searched the web for the word crowdsourcing, the subject of an article by contributing writer Jeff Howe. He took a screenshot of what he found, a total of three brief mentions, and forwarded it to the author, advising that Howe save it as a “historical document.” Howe didn’t have to wait long to see history in action. Within nine days Google was returning 182,000 hits. Nor was it a fleeting fad. Three years later the number had multiplied to 1,620,000, with regular appearances in the mainstream media, from the Washington Post to Fox News, where crowdsourcing was averaging two hundred new mentions each month. There’s a simple explanation for the neologism’s success. Howe had detected a trend and given it a word. The backstory, which Howe posted on his personal blog, crowdsourcing.com, supports this notion: In January Wired asked me to give a sort of “reporter’s notebook” style presentation to some executives. I had recently been looking into common threads behind the ways advertising agencies, TV networks and newspapers were leveraging user-generated content, and picked that for my topic. Later that day I called my editor at Wired, Mark Robinson, and told him I thought there was a broader story that other journalists were missing, ie, that users weren’t just making dumbpet-trick movies, but were poised to contribute in significant and measurable ways in a disparate array of industries. In what Howe characterizes as “a fit of back-and-forth wordplay,” he and Robinson came up with a term that riffed off the title of a business book popular at the time, James Surowiecki’s The Wisdom of Crowds, while also suggesting opensource software and corporate outsourcing. When “The Rise of Crowdsourcing” was finally published six months later, the last of these three roots was explicitly evoked in the teaser: “Remember outsourcing? Sending jobs to India and China is so 2003. The new pool of cheap labor: everyday people using their spare cycles to create content, solve problems, even do corporate R & D.”

In the present era of Big Data, with continuously increasing amounts of user-generated content, it is becoming a challenge to understand the relation between the content that is available on the Web and the users who are generating that content. Researchers have come up with many ways to understand today's Web better. One of the recently introduced concepts is a Web observatory (WO). This article provides a deep understanding about web observatories. It discusses the status of existing WO systems. The article investigates and gathers the common practices of WOs. This research has implications for researchers and communities in the adoption of the WO concept. The article highlights the challenges of WOs, such as data crawling, privacy and security. It also provides future research and development directions. The article provides a comparative analysis of existing WOs. It discusses the architecture of WOs. It presents components of a WO in a coherent manner and finally provides insights into challenges and limitations of WOs.

The concepts of the participative Web, mass collaboration, and collective intelligence grow out of a set of Web methodologies and technologies which improve interaction with users in the development, rating, and distribution of user-generated content. UGC is one of the cornerstones of Web 2.0 and is the core concept of several different kinds of applications. UGC suggests new value chains and business models; it proposes innovative social, cultural, and economic opportunities and impacts. However, several open issues concerning semantic understanding and managing of digital information available on the Web, like information overload, heterogeneity of the available content, and effectiveness of retrieval are still unsolved. The research experiences we present in this chapter, described in literature or achieved in our research laboratory, are aimed at reducing the gap between users and information understanding, by means of collaborative and cognitive filtering, sentiment analysis, information extraction, and knowledge conceptual modeling.

Although tagging is a widely accepted practice on the Social Web, it raises various issues like tags ambiguity and heterogeneity, as well as the lack of organization between tags. We believe that Semantic Web technologies can help solve many of these issues, especially considering the use of formal resources from the Web of Data in support of existing tagging systems and practices. In this article, we present the MOAT—Meaning Of A Tag—ontology and framework, which aims to achieve this goal. We will detail some motivations and benefits of the approach, both in an Enterprise 2.0 ecosystem and on the Web. As we will detail, our proposal is twofold: It helps solve the problems mentioned previously, and weaves user-generated content into the Web of Data, making it more efficiently interoperable and retrievable.

The nature of the enterprise and the way people work is changing rapidly. The enabling power and competitive advantage of new social and participative technologies will benefit those that recognize the way work is changing. Web 2.0, the “second phase” of the Web, is the foundation of a new and improved Enterprise 2.0. Enterprise 2.0 provides, through a web of interconnected applications, services, and devices, the capabilities for enterprise employees and vendors to be more competitive and productive and for enterprise customers to be more engaged and loyal by accessing the right information from the right people at the right time. This paper describes Enterprise 2.0 management challenges and issues identified by Chief Information Officers, which include the unauthorized use of services and technologies, the integration of a myriad of technologies and capabilities, and the potential compliance and security implications. The authors have proposed a conceptual framework that explores the relationships of three Enterprise 2.0 dimensions – technology, its use, and how resulting user-generated content may lead to business value – with management implications affecting IT culture and policies within the enterprise. This paper provides observations and suggestions for future research.
