The Pew Internet and American Life Project has just released a report on Tagging with some very interesting statistics (”28% of internet users have tagged or categorized content online such as photos, news stories or blog posts. On a typical day online, 7% of internet users say they tag or categorize online content.”)  There’s also an interview with Tagsonomy blogger David Weinberger:

Q: Why do you think Internet users are drawn to tagging?

Weinberger: It’s really useful. Compare your traditional computer system to organize your digital photos to using a tagging system. Instead of having to stick a photo into a single folder — say, “trips 2006” — you can easily tag it as “Italy,” “anniversary,” “sunset,” “mountains,” and “no kids.” You can assemble instant virtual albums of all your anniversary photos, or all your photos of all your trips to Italy, etc.

There’s an altruistic appeal to tagging as well. Tagging at public sites can give you a sense that you’re adding to a shared stream of knowledge. At del.icio.us, or other such sites, tag a page “robotics” and you know that it’s automatically added to the list of pages tagged that way, so anyone else interested in that topic can find it.

HPL-2007-6 A Classification-Based Approach to Policy Refinement - Udupi, Yathiraj B.; Sahai, Akhil; Singhal, Sharad
Keyword(s): classification; policy refinement; decomposition; SLA
Abstract: Systems are typically designed based on certain high-level goals, such as performance and availability. On the other hand, during operation, usually only low level metrics (e.g., CPU utilization) are measured, and system administrators or experts use domain knowledge to implicitly map bounds on thes ...

HPL-2007-2 On the Hardness of Decoding the Gale--Berlekamp Code - Roth, Ron M.; Viswanathan, Krishnamurthy
Keyword(s): Gale--Berlekamp switching game; Hadamard matrices; intractable problems; maximum-likelihood decoding; NP-complete problems
Abstract: The Gale--Berlekamp (in short, GB) code is the dual code of the binary product code in which the horizontal and vertical constituent codes are both the parity code. It is shown that the problem of deciding whether there is a codeword of the GB code within a prescribed distance from a given received ...

HPL-2006-26(R.1) Improving Usability by Adding Security to Video Conferencing Systems - Mitchell, April Slayden; Karp, Alan H.
Keyword(s): security; user interface design; usability
Abstract: Business travel is at an all-time high despite the plethora of video conferencing applications available in the world today. One major drawback in many of these applications is a confusing interface which may require a large amount of setup time and training. The second major drawback is lack of sec ...

Keyword(s): user studies; user interface design; utility computing; market-based resource allocation; 3D animation; CGI rendering; SE3D
Abstract: This study made a large amount of remote, computer-processing power (the HP Labs Utility Rendering Service) available to a group of animators to support each of them in the creation of a computer-graphics short film for the SE3D showcase. This event was organized by HP Labs in collaboration with Aut ...

HPL-2006-182 Blades as a General-Purpose Infrastructure for Future System Architectures: Challenges and Solutions - Leigh, Kevin; Ranganathan, Parthasarathy
Keyword(s): blades; c-Class; power
Abstract: Bladed servers are increasingly being adopted in enterprise data centers by virtue of the improved benefits they offer in form factor density, modularity, and more robust management for control and maintenance with respect to rack-optimized servers. In the future, such servers are likely to form the ...

HPL-2006-128 Privacy-Preserving Verification of Aggregate Queries on Outsourced Databases - Haber, Stuart; Horne, William; Sander, Tomas; Yao, Danfeng
Keyword(s): cryptography; integrity; privacy
Abstract: It is often desirable to be able to guarantee the integrity of historical data, ensuring that any subsequent modifications to the data can be detected. It would be especially convenient to extend such proofs of integrity to certain computations performed later using the historic data. We approach th ...
