WEB 2.0: The Dawn of Emergent Collaboration - Prof. Andrew P. McAfee
Search For any information platform to be valuable, its users must be able to find what they are looking for …
Links Google made a huge leap forward in Internet search quality by taking advantage of the information contained in links between Web pages … Search technologies works best when there’s dense link structure that changes over time and reflects the opinion of many people … many people have to be given the ability to build links …
Authoring Internet blogs and Wikipedia have shown that many people have a desire to author – to write for a broad audience … most people have something to contribute, whether it’s knowledge, insight, experience, a comment, a fact, an edit, a link and so on, and authorship is a way to elicit these contributions. Blog let people author individually, and wikis enable group authorship …
Tags … after better searching mechanisms, what experienced users wanted most from their companies’ intranets was better categorization of content … a folksonomy (a categorization system developed over time by folks) … in some ways the opposite of a taxonomy, which is an up front categorization scheme developed by an expert …
Extensions … algorithms to say to users “If you liked that, then by extensions you’ll like this”. Amazon’s recommendations were an early example of the use of extensions on the Web …
Signals Even with powerful tools to search and categorize platform content, a user can easily feel overwhelmed. New content is added so often that it become a full-time job just to check for updates on all sites of interest. The final element of the SLATES infrastructure is technology to signal users when new content of interest appears … A novel technology called RSS …

Social software Social software encompasses a range of software systems that allow users to interact and share data. This computer-mediated communication has become very popular with social sites like MySpace and Facebook , media sites like Flickr and YouTube , and commercial sites like Amazon.com and eBay . Many of these applications share characteristics like open APIs, service oriented design, and the ability to upload data and media. The terms Web 2.0 and (for large-business applications) Enterprise 2.0 are also used to describe this style of software. The more specific term collaborative software applies to cooperative information sharing systems, and is usually narrowly applied to the software that enables collaborative work functions.
Social software & “The Wisdom of Crowds” “ Social software” is an umbrella term that applies to any tool that allows two or more persons to collaborate while each person is in a different location. The collaboration may occur in real time or at different times while the locations may span continents or simply an office building. The ultimate goal of social software is to build a community of practice or knowledge network in which participants constantly give and receive valuable information. The relevant issues in social software are, in order, the people who use and need information, the quality and context of that information, the timely (and if necessary, secure) transfer of that information, and finally, the social software tools themselves. Neither information nor social software tools should ever take precedence over the people or communities that are involved in a given project. The Wisdom of Crowds: Why the Many Are Smarter Than the Few and How Collective Wisdom Shapes Business, Economies, Societies and Nations , first published in 2004, is a book written by James Surowiecki
Blogs , short for web logs, are like online journals for a particular person. The owner will post a message periodically, allowing others to comment. Topics often include the owner's daily life, views on politics or a particular subject important to them. Blogs mean many things to different people, ranging from "online journal" to "easily updated personal website." While these definitions are technically correct, they fail to capture the power of blogs as social software. Beyond being a simple homepage or an online diary, some blogs allow comments on the entries, thereby creating a discussion forum .
A Wiki is a page or collection of Web pages designed to enable anyone who accesses it to contribute or modify content, using a simplified markup language. Wikis are often used to create collaborative websites and to power community websites. The collaborative encyclopedia Wikipedia is one of the best-known wikis. Wikis are used in business to provide intranets and Knowledge Management systems . Ward Cunningham, developer of the first wiki software, WikiWikiWeb , originally described it as "the simplest online database that could possibly work". "Wiki" (/wiːkiː/) is a Hawaiian word for "fast". "Wiki" can be expanded as "What I Know Is,“.
Social Bookmarking is a method for Internet users to store, organize, search, and manage bookmarks of web pages on the Internet with the help of metadata. In a social bookmarking system, users save links to web pages that they want to remember and/or share. These bookmarks are usually public, and can be saved privately, shared only with specified people or groups, shared only inside certain networks, or another combination of public and private domains. Most social bookmark services encourage users to organize their bookmarks with informal tags instead of the traditional browser-based system of folders. Many social bookmarking services provide web feeds for their lists of bookmarks, including lists organized by tags
RSS Really Simple Syndication/Rich Site Summary/ …
RSS is a family of Web feed formats used to publish frequently updated works – such as blog entries, news headlines, audio, and video – in a standardized format. An RSS document (which is called a " feed ", " web feed ", or " channel ") includes full or summarized text, plus metadata such as publishing dates and authorship. Web feeds benefit publishers by letting them syndicate content quickly and automatically.
They benefit readers who want to subscribe to timely updates from favored websites or to aggregate feeds from many sites into one place.
In web development, a Mashup is a web application that combines data from more than one source into a single integrated tool; an example is the use of cartographic data from Google Maps to add location information to real-estate data, thereby creating a new and distinct web service that was not originally provided by either source. Content used in mashups is typically sourced from a third party via a public interface or API (web services). Other methods of sourcing content for mashups include Web feeds (e.g. RSS or Atom ), and screen scraping . Many people are experimenting with mashups using Amazon , eBay , Flickr , Google , Microsoft , Yahoo and YouTube APIs, which has led to the creation of mashup editors .
A Social Network service focuses on building online communities of people who share interests and activities, or who are interested in exploring the interests and activities of others.
Most social network services are web based and provide a variety of ways for users to interact, such as e-mail and instant messaging services. Social networking has created new ways to communicate and share information .
Social networking websites are being used regularly by millions of people, and it now seems that social networking will be an enduring part of everyday life.
Media sharing occurs in online social networks and digital communities with a comprehensive platform and diversified interfaces to aggregate, upload, compress, host and distribute images, text, applications, videos, audio, games and new media. It is the interactive process of sending via email, instant message, text message, posting or linking to media on a website or blog and other methods of sharing media to a targeted audience. As media is shared it takes on a variety of different contexts and meanings. The same video posted on YouTube and on Digg will generate different communication outcomes as the same video being sent to a family member and a college buddy
Taxonomy is the practice and science of classification. Taxonomies, or taxonomic schemes, are composed of taxonomic units , or kinds of things that are arranged frequently in a hierarchical structure. Typically they are related by subtype-supertype relationships, also called parent-child relationships.
Folksonomy (also known as collaborative tagging , social classification , social indexing , and social tagging ) is the practice and method of collaboratively creating and managing tags to annotate and categorize content . Folksonomy describes the bottom-up classification systems that emerge from social tagging.
In contrast to traditional subject indexing , metadata is generated not only by experts but also by creators and consumers of the content. Usually, freely chosen keywords are used instead of a controlled vocabulary . Folksonomy (from folk + taxonomy ) is a user-generated taxonomy.
A Library 2.0 definition ( … one among many) “ Library 2.0 simply means making your library’s space (virtual and physical) more interactive, collaborative, and driven by community needs. Examples of where to start include blogs, gaming nights for teens, and collaborative photo sites. The basic drive is to get people back into the library by making the library relevant to what they want and need in their daily lives…to make the library a destination and not an afterthought.” (Sarah Houghton) LIBRARY 2.0 LIBRARY 0.0
Please ….. pay attention to meme !! A meme (pronounced /miːm/ )  consists of any idea or behavior that can pass from one person to another by learning or imitation. Examples include thoughts, ideas, theories, gestures, practices, fashions, habits, songs, and dances. Memes propagate themselves and can move through the cultural sociosphere in a manner similar to the contagious behavior of a virus. (Wikipedia – Richard Dawkins “The selfish Gene” 1976)
Job 2.0 or … (no job)? Maybe your users could already have been infected (or contaminated) and looking for “Services 2.0” … … and what happens if Library is still 1.0 ? … users don’t use it … … and if they don’t use library … … library becomes useless … … as well librarians working there … … and if a worker is useless …
