The purpose of this study was to improve the quality of students’ online discussion of assigned readings in an online course. To improve the focus, depth, and connectedness of online discussion, the first author designed a text–focused Wiki that simultaneously displayed the assigned reading and students’ comments side by side in adjacent columns. In the text–focused Wiki, students were able to read the assigned text in the left column and type their comments or questions in the right column adjacent to the sentence or passage that sparked their interest. In post–participation surveys, data were gathered about students’ experiences in the text–focused Wiki and prior experiences in threaded discussion forums. Students reported more focus, depth, flow, idea generation, and enjoyment in the text–focused Wiki.

The exponential growth of diverse types of biological data presents the research community with an unprecedented challenge and opportunity. The challenge is to stay afloat in the flood of biological data, keeping it as accessible, up-to-date, and integrated as possible. The opportunity is to cultivate new models of data curation and exchange that take advantage of direct participation by a greater portion of the community.

The Semantic Web isn't just about putting data on the web. It is about making links, so that a person or machine can explore the web of data. With linked data, when you have some of it, you can find other, related, data.

Like the web of hypertext, the web of data is constructed with documents on the web. However, unlike the web of hypertext, where links are relationships anchors in hypertext documents written in HTML, for data they links between arbitrary things described by RDF,. The URIs identify any kind of object or concept. But for HTML or RDF, the same expectations apply to make the web grow:

1.

Use URIs as names for things
2.

Use HTTP URIs so that people can look up those names.
3.

When someone looks up a URI, provide useful information.
4.

Include links to other URIs. so that they can discover more things.

Collaborative tagging describes the process by which many users add metadata in the form of keywords to shared content. Recently, collaborative tagging has grown in popularity on the web, on sites that allow users to tag bookmarks, photographs and other content. In this paper we analyze the structure of collaborative tagging systems as well as their dynamical aspects. Specifically, we discovered regularities in user activity, tag frequencies, kinds of tags used, bursts of popularity in bookmarking and a remarkable stability in the relative proportions of tags within a given url. We also present a dynamical model of collaborative tagging that predicts these stable patterns and relates them to imitation and shared knowledge.

There is a revolution happening on the Internet that is alive and building momentum with each passing tag. With the advent of social software and Web 2.0, we usher in a new era of Internet order. One in which the user has the power to effect their own online experience, and contribute to others’. Today, users are adding metadata and using tags to organize their own digital collections, categorize the content of others and build bottom-up classification systems. The wisdom of crowds, the hive mind, and the collective intelligence are doing what heretofore only expert catalogers, information architects and website authors have done. They are categorizing and organizing the Internet and determining the user experience, and it’s working. No longer do the experts have the monopoly on this domain; in this new age users have been empowered to determine their own cataloging needs. Metadata is now in the realm of the Everyman.

People are changing the way that they consume online information, as well as their expectations about its delivery. The social nature of the Web brings with it an expectation of interaction with information and modern Web design is reflecting that. There are now alternate forms of navigation including the ability to browse by user, tag clouds, tabbed navigation etc. Advances in technology along with these shifts in user expectations are affecting the way that information is laid out on a webpage. Today’s websites are aiming for intuitive and usable interfaces which are continuously evolving in response to user needs. Website designers are approaching information design differently and designing simple, interactive websites which incorporate advancements in Web interface design, current Web philosophies, and user needs. Information design for the New Web is simple, it is social, and it embraces alternate forms of navigation.
