The Microsoft Research Community Technologies group focuses on the study and enhancement of computer mediated collective action systems. In this talk I will present recent developments in projects that highlight and attempt to enhance computer mediated collective action: Netscan, SNARF and AURA. Netscan is a set of tools and services for online communities. Netscan manufactures “social accounting metadata” about Usenet newsgroups and web boards, providing reports about discussion spaces and individuals that highlight patterns of activity and contribution in tabular and graphical forms. We have recently developed faster data update models, new Web service interfaces, a custom community portal page, and a new information visualization application (“Usenet Views”) that makes it simple to map and chart newsgroup communities. New sources of community content, from web boards, forums, discussion boards, email lists, and related repositories of threaded conversation are being analyzed by the Netscan system. SNARF a

It is risky for technologists to ignore the non-technical context in which their systems will be deployed, just as it is risky for policy makers to ignore the limits and potential of technology. Yet such insularity is all too common. The results are unfortunate but not surprising. This lecture explores the structure dialogs take to bring about what might be termed "security failings" by revisiting: identity theft, electronic voting, digital right management, and the overall vulnerabilities of today's deployed software.

Much of what we want to know about other people is not directly perceivable. Are you a nice person? Did you really like the cake I baked? If we got married, would you be a good parent to our children? Instead, we rely on signals, which are perceivable features or actions that indicate the presence of those hidden qualities. Yet not all signals are reliable. It is beneficial for the con-man to seem nice, for the guest to seem to like the burnt cake, for the unsuitable suitor to seem as attractive as possible. While these deceptions benefit the deceiver, they may be quite costly for the recipient. What keeps signals honest — and why are some signals more reliable than others? Signaling theory provides a framework for understanding these dynamics. Among other things, it shows how the cost of many seemingly extravagant displays is not wasteful expenditure, but useful for ensuring the reliability of the display as a signal. In this talk I will show how signaling theory can be used for the design and analysis of so

Co-sponsored by: UC Berkeley School of Information, Berkeley Center for Law & Technology, boalt.org. With the radical changes in information production that the Internet has introduced, we stand at an important moment of transition, says Yochai Benkler. The phenomenon he describes as social production is reshaping markets, while at the same time offering new opportunities to enhance individual freedom, cultural diversity, political discourse, and justice. But these results are by no means inevitable: a systematic campaign to protect the entrenched industrial information economy of the last century threatens the promise of today's emerging networked information environment. In this comprehensive social theory of the Internet and the networked information economy, Benkler describes how patterns of information, knowledge, and cultural production are changing - and shows that the way information and knowledge are made available can either limit or enlarge the ways people can create and express themselves. He desc

Media have changed ideas about the self and society for centuries, from vernacular print in the Reformation to the 20th Century’s reference to life’s intense moments as being “like a movie.” What might happen as today’s media blur accelerates? It is not just that news, information and entertainment are in continual overlap, with print, audio and visual streams interchanging. The ideal is that no information is lost, and we are “always on,” in perpetual connection with continual feeds. In this talk I will discuss some of the major trends in their historic context, and sketch out the likely consequences.

Cautious cars? We already have them, cautious and sometimes frightened. Cranky kitchens, not yet, but they are coming. Our products are getting smarter, more intelligent, and more demanding, or if you like, bossy. This trend brings with it many special problems and unexplored areas of applied psychology. In particular, our devices are now part of a human-machine social ecosystem, and therefore they need social graces, superior communicative skills, and even emotions: machine emotions, to be sure, but emotions nonetheless. In this talk I explore the reasons for such statements, the issues that need to be considered, and the dangers that have already occurred because designers still think of each device as alone, and self-contained.

The sudden and unexpected importance of the Wikipedia, a free online encyclopedia created by tens of thousands of volunteers and coordinated in a deeply decentralized fashion, represents a radical new modality of content creation by massively distributed collaboration. This talk will discuss the unique principles and values which have enabled the Wikipedia community to succeed and will examine the intriguing prospects for application of these methods to a broad spectrum of intellectual endeavors.
