This exploratory study examines the relationships between article and Talk page contributions and their effect on article quality in Wikipedia. The sample consisted of three articles each from the hard sciences, soft sciences, and humanities, whose talk page and article edit histories were observed over a five-month period and coded for contribution types. Richness and neutrality criteria were then used to assess article quality and results were compared within and among subject disciplines. This study reveals variability in article quality across subject disciplines and a relationship between Talk page discussion and article editing activity. Overall, results indicate the initial article creator's critical role in providing a framework for future editing as well as a remarkable stability in article content over time.

This article is a guide for collection developers at the point of considering a metadata schema for their digital collection. The nine questions asked in this article will assist a developer in clarifying how he wants the collection to be organized, described, and used. This article uses examples to illustrate how these questions guided the development of a digital collection built at the University of Southern California.

Using the 1994, South Canyon fire in Colorado as a case study, this article suggests Taylor's (1993) concept of worldview functions as an important "frame" for organizational sensemaking (Weick, 1995a). Taylor argues that organizations use either an "activity" or "particle" orientation. An activity view focuses attention on organizational units while a particle view sees the organization from the point of view of the product or customer. Results from this study indicate that an organization's worldview functions as an overarching metaphor that influences sensemaking and decision-making processes, and that the worldview perspective in retrospective accounts may differ from that of the participants themselves.

I want a page, a site, a thing that is created, curated, edited, and discussed. It's a blog that treats a topic as an ongoing and cumulative process of learning, digging, correcting, asking, answering. It's also a wiki that keeps a snapshot of the latest knowledge and background. It's an aggregator that provides annotated links to experts, coverage, opinion, perspective, source material. It's a discussion that doesn't just blather but that tries to accomplish something (an extension of an article like this one that asks what options there are to bailout a bailout). It's collaborative and distributed and open but organized.

Wikipedia, the free online encyclopedia, has challenged the way that reference works are used and understood, and even the way that the collective enterprise of knowledge construction and circulation is itself conceptualized. The article presents an ethnographic study of Wikiversity, an educationally-oriented sister project to Wikipedia. It begins by providing an overview of the orientations and aims of Wikiversity, which seeks to provide for participants both open educational contents and an open educational community. It then undertakes a detailed examination of this project's emerging, overlapping communities and cultures by providing descriptions produced through a combination of ethnographic techniques. These descriptions focus on the experiences of a participant-observer in the context of an 11-week course developed and delivered via Wikiversity, titled Composing Free and Open Online Educational Resources. These descriptions are discussed and interpreted through reference to qualitative studies of the more developed dynamics of the Wikipedia effort - allowing this study to trace the possible trajectories for the future development of the fledgling Wikiversity project. In this way, this paper investigates the communal and cultural dynamics of an undertaking that - should it meet only with a fraction of Wikipedia's success - will be of obvious significance to education generally.

To manage information quality (IQ) effectively, one needs to know how IQ changes over time, what causes it to change, and whether the changes can be predicted. In this paper we analyze the structure of IQ change in Wikipedia, an open, collaborative general encyclopedia. We found several patterns in Wikipedia's IQ process trajectories and linked them to article types. Drawing on the results of our analysis, we develop a general model of IQ change that can be used for reasoning about IQ dynamics in many different settings, including traditional databases and information repositories.

This article explores relationships between players and the owners of the massively multiplayer online games (MMOG) they inhabit. Much of the language around these large scale communities currently focuses on "management." Viewing these complex social systems as essentially mechanical in nature has led to a preoccupation with creating or retrofitting systems which can be constantly monitored, tuned, regulated, and controlled. Though the language often turns to things like "cheating," "griefing," and "disruption of the magic circle," the underlying anxiety about unruliness, transgressiveness, and the emergent nature of these spaces as sites of culture needs to be more fully addressed, as well as the early formulations of the "imagined player" that shape the design process. Players are central productive agents in game culture and more progressive models are needed for understanding and integrating their work in these spaces. Drawing on the long tradition of participatory design this piece explores some alternative frameworks for understanding the designer/player relationship are proposed.

I think that needs to change fundamentally, so that corporations really are in the business of serving all of the factors that help generate wealth-all of the stakeholders, in effect. One way to describe what has to happen, and the way that the situation in the future would be different, would be to describe it as a series of transformations. The first would be a transformation in the market. There would be a real revolution in pricing. Things that are environmentally destructive would be-if they were really destructive-almost out of reach, prohibitively expensive.

Vannevar Bush's 1945 article, "As We May Think," has been much celebrated as a central inspiration for the development of hypertext and the World Wide Web. Less attention, however, has been paid to Bush's motivation for imagining a new generation of information technologies; it was his hope that more powerful tools, by automating the routine aspects of information processing, would leave researchers and other professionals more time for creative thought. But now, more than sixty years later, it seems clear that the opposite has happened, that the use of the new technologies has contributed to an accelerated mode of working and living that leaves us less to think, not more. In this talk I will explore how this state of affairs has come about and what we can do about it.

The contention made in this article is that ontologies are pivotal to several seemingly disparate technical endeavours that are currently emergent and have had more or less publicity. These include Event Driven Architecture (EDA), Complex Event Processing (CEP), Service Oriented Architecture (SOA), Master Data Management (MDM), which are supported by specific ontological initiatives most notably the Semantic Web, which is further leveraged by Model Driven Architecture (MDA). Furthermore how these efforts are all dependent on the adherence to common standards. These endeavours, and their complementary interrelationships, and specifically their relationship to ontology, are explored in more detail below.

Sensemaking systems don't only help people find stuff faster. That's just the information retrieval part. The bigger story is about augmenting and amplifying our abilities to make sense. Sensemaking adds things like skimming, power reading, organizing, spotting patterns, tracing social networks, taking notes, summarizing, drilling for details, and flagging biases. Reading an article is different from reading a book, and that's different from reading from a collection or stream. Radically new forms of human-information interaction are being enabled by these new technologies. Sensemaking systems not only have front ends (visualization), but also back ends (content analytics and reasoning).

Businesses are moving beyond marketing in virtual worlds and are exploring other applications of virtual worlds (see a recent BusinessWeek article & slideshow). Enabling collaboration among remote workers is one such application (see our past posts and paper on this topic). A variety of virtual world options or platforms have been available for supporting remote work and these include Second Life, Qwaq, Forterra, and Tixeo. Last week I had the rare opportunity to see an emerging virtual world called Wonderland, the product of an open source project, Project Wonderland, sponsored by Sun Microsystems. During a conference call with our colleague Nicole Yankelovich, Principal Investigator of the Collaborative Environments Project at Sun Microsystems, Becky Jestice and I were lucky enough to get a tour of Wonderland. Nicole graciously spent over an hour to show us some of the impressive features of Wonderland. The tour was so impressive that I want to devote a post to some key aspects of Wonderland: * Virtual meeting participants can use voice to communicate with one another; * If necessary, participants can connect to a Wonderland meeting via telephone; * Private conversations between participants are possible in a virtual meeting; * Participants can share applications; and * Anyone can try out Wonderland (see instructions below).

This article describes the motivation for and development of a project I have called PepysMap. PepysMap was inspired by the excellent 'blog of the diary of Samuel Pepys run by Phil Gyford 1. Phil posts diary entries day by day (currently for the year 1662). Each blog post contains the text of the diary entry hyperlinked to pages containing detail of people, places and cultural artifacts referenced from the text. The goal of PepysMap is to shadow the development of the Pepys blog by creating a topic map for each diary entry, showing the relationships between people, places and cultural artifacts.

Zotero is an easy-to-use yet powerful research tool that helps you gather, organize, and analyze sources (citations, full texts, web pages, images, and other objects), and lets you share the results of your research in a variety of ways. An extension to the popular open-source web browser Firefox, Zotero includes the best parts of older reference manager software (like EndNote)-the ability to store author, title, and publication fields and to export that information as formatted references-and the best parts of modern software and web applications (like iTunes and del.icio.us), such as the ability to interact, tag, and search in advanced ways. Zotero integrates tightly with online resources; it can sense when users are viewing a book, article, or other object on the web, and-on many major research and library sites-find and automatically save the full reference information for the item in the correct fields. Since it lives in the web browser, it can effortlessly transmit information to, and receive information from, other web services and applications; since it runs on one's personal computer, it can also communicate with software running there (such as Microsoft Word). And it can be used offline as well (e.g., on a plane, in an archive without WiFi).

The NeuroCommons project seeks to make all scientific research materials - research articles, annotations, data, physical materials - as available and as useable as they can be. We do this by both fostering practices that render information in a form that promotes uniform access by computational agents - sometimes called "interoperability". We want knowledge sources to combine meaningfully, enabling semantically precise queries that span multiple information sources. Our work covers general data and knowledge sources used in computational biology as well as sources specific to neuroscience and neuromedicine. The practices that we develop and promote are designed to play well on the Semantic Web. We view our technical work not as creating a new service or content library, although we do both, but rather as helping to promote the growth of semantically linked scientific information.

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 Cognitive Edge weblog contains an interesting exchange on the nature and role of storytelling in organizations. It was prompted by blog author Dave Snowden's reading of an article by Gabrielle Dolan of One Thousand and One, an Australian consultancy specialising in storytelling as a tool for organisational development. Dave Snowden is well known for his work on the role of narrative and complexity theory in organizational sensemaking.

And when all these things exist, what will happen to our memories? As the Atlantic article suggests, we may find that the net effect is to "scatter our attention and diffuse our concentration," - or, as it argues in another part, we could spur a "golden age of intellectual discovery and universal wisdom." The result may well depend on the quality of the efforts.

Interdisciplinary research programs at Harvard and elsewhere naturally tend to be distributed geographically, across campuses and departments. Effective collaboration for these programs requires the ability to bridge distance, which in turn implies digital collaboration, and therefore abilities to publish and discuss on-line content such as articles, news, and perspectives; to provide semantic context to on-line content for more powerful interactions within multiple sub-disciplines and to integrate as well as distinguish the individual contributions of many scientific workers.
