On the shoulders of giants

on Comments (3)

I have used the phrases “publish -> filter” and “filter -> publish” in a number of recent blog posts related to scientific publishing, but had been unable to find proper attribution to them with a casual search. While reading Kathleen Fitzpatrick’s draft of Planned Obsolescence, I came across the phrase “filter-then-publish” which she attributed to Clay Shirky’s “Here Comes Everybody.” I am adding that book to the top of my reading list right now.

Marti Hearst: Google Tech Talk on Search User Interfaces

on

Marti Hearst recently gave a talk at Google related to the themes in her book. She does a good job of explaining the challenges and opportunities related to interactive information seeking, including design, evaluation, query reformulation, integrating navigation and search, information visualization as it relates to search, and future trends. While most of this is music to the ears of HCIR types, her discussion of collaborative search (around minute 46) is particularly “relevant:” Marti spends a good deal of time on our paper on collaborative search, describing the various models of collaboration and showing some figures from our paper. The talk is on YouTube, the paper is on the web. Questions and comments are very welcome.

ps: Marti’s mention of Diane “Green” in minute 24 actually refers to Diane Kelly, whose well-received paper on query suggestion was presented at SIGIR 2009.

Can open source improve open reviewing?

on Comments (8)

Naboj is an overlay on arXiv.org that allows people to comment on articles, to rate articles, and (unlike SciRate.com) to rate the reviews as well. Unfortunately, the rather minimal interface does not make it easy to organize the display by highly-rated reviewers or by thoroughly-reviewed papers (i.e., papers with reviews that others found useful), or restrict search to particular domains.

These limitations are not inherent in the design of the review process or the data collected on the site, but rather are probably indicative of an under-resourced effort. I wonder if an open-source approach to the design of these kinds of tools would result in a more usable (and thus more useful) way of managing an open peer review process. Is open source the way to open reviewing? I would certainly consider contributing to it.

Reviewing the reviewers

on Comments (11)

I’ve written about some alternatives to the current review process, and I believe one of ways in which the current process can be improved is by formal recognition of reviewers’ efforts. While many conferences and journals acknowledge reviewers by publishing their names, this does not reflect the quality of the effort put in by some reviewers. A more lasting and public recognition of quality reviewers may be one way to improve the quality of this volunteer effort.

Interestingly, the APS recently instituted a policy of recognizing referees who review the articles submitted to the various APS journals.

The basis for choosing the honorees was the quality, number, and timeliness of their reports, without regard for membership in the APS, country of origin, or field of research. Individuals with current or very recent direct connections to the journals, such as editors and editorial board members, were excluded.

Renewable energy from slow water currents

on

People have been trying to harness wave energy for decades, and of course more traditional – and more destructive – hydroelectric projects like dams provide power to hundreds of millions of people. Now, researchers at the University of Michigan are creating a system for fish-friendly power generation from slow-moving water currents in rivers or oceans – and it’s not that expensive; about a third the cost of cheap solar. Here’s the story:

Slow-moving ocean and river currents could be a new, reliable and affordable alternative energy source. A University of Michigan engineer has made a machine that works like a fish to turn potentially destructive vibrations in fluid flows into clean, renewable power.

The machine is called VIVACE. A paper on it is published in the current issue of the quarterly Journal of Offshore Mechanics and Arctic Engineering.

VIVACE is the first known device that could harness energy from most of the water currents around the globe because it works in flows moving slower than 2 knots (about 2 miles per hour.) Most of the Earth’s currents are slower than 3 knots. Turbines and water mills need an average of 5 or 6 knots to operate efficiently.

DarwinTunes: a social experiment

on

DarwinTunes bills itself as a “test tube for cultural evolution.” It’s an online experiment being run by researchers at Imperial College London. We often talk about the evolution of social media or cultural memes – but is that just a metaphor, or is it really evolution?

Generating 3D models from webcams

on Comments (2)

One highly inconvenient thing about working with virtual worlds or 3D content in general is: where do your 3D models come from (especially if you’re on a budget)? A talented but (inevitably) overworked 3D artist? An online catalog of variable quality and cost? Messing around yourself with tools like SketchUp or Blender? What if you want something very specific, very quickly? The MIR (Mixed and Immersive Realities) team here at FXPAL is very interested in these questions and has done some work in this area. Others are working on it too: here’s an elegant demo from Qi Pan at the University of Cambridge, showing the construction of a model with textures from a webcam image:

ARdevcamp: Augmented Reality unconference Dec. 5 in Mountain View, New York, Sydney…

on Comments (1)

We’re looking forward to participating in ARdevcamp the first weekend in December. It’s being organized in part by Damon Hernandez of the Web3D Consortium, Gene Becker of Lightning Labs, and Mike Liebhold of the Institute for the Future (among others – it’s an unconference, so come help organize!) So far, there are ~60 people signed up; I’m not sure what capacity will be, but I’d sign up soon if you’re interested. You can add your name on the interest list here.

From the wiki:

The first Augmented Reality Development Camp (AR DevCamp) will be held in the SF Bay Area December 5, 2009.

After nearly 20 years in the research labs, Augmented Reality is taking shape as one of the next major waves of Internet innovation, overlaying and infusing the physical world with digital media, information and experiences. We believe AR must be fundamentally open, interoperable, extensible, and accessible to all, so that it can create the kinds of opportunities for expressiveness, communication, business and social good that we enjoy on the web and Internet today. As one step toward this goal of an Open AR web, we are organizing AR DevCamp 1.0, a full day of technical sessions and hacking opportunities in an open format, unconference style.

AR DevCamp: a gathering of the mobile AR, 3D graphics and geospatial web tribes; an unconference:
# Timing: December 5th, 2009
# Location: Hacker Dojo in Mountain View, CA

Looks like there will be some simultaneous ARdevcamp events elsewhere as well – New York and Manchester events are confirmed; Sydney, Seoul, Brisbane, and New Zealand events possible but unconfirmed.

Mathematical and Musical Adventures

on Comments (2)

The next talk in the Bay Area Mathematical Adventures series is this Friday. Robert Bryant, the current director of MSRI, will speak on “Rolling and Tumbling—The idea of Holonomy.” It sounds like a fun talk; he’ll illustrate his talk with “everyday and some not-so-everyday toys.”

I’ve posted the slides from my Bay Area Mathematical Adventures talk last month on From Photographs to Models: The Mathematics of Image-Based Modeling. I blogged about that experience here. I had hoped to post a link to the video at the same time, but it isn’t ready yet. I never feel that a talk is fully captured from just the slides, especially one that was designed to be interactive. I will post a link to the video once it is up.

I’d be tempted to go to Bryant’s talk except that I’m singing that night. Two FXPAL folks, Bill van Melle and I, sing in the 40 voice Bay Choral Guild. We have concerts Fri, Sat, and Sun at various Bay Area locations. Come if you are in the area and would enjoy a concert of festive Baroque choral works performed by our excellent group together with an outstanding group of soloists and musicians!

Google Scholar is now legal

on

In 2001, when we were thinking about how to use e-books for legal research, we partnered with Lexis Nexis to study a moot court class in a law school. Without access to the documents that we obtained through Lexis, we would not have been able to engage the students and to explore potential designs for such devices.

But that was eight years ago. Today, we could resort to Google Scholar: A couple of days ago, Google announced on its blog that it will be including full text legal opinions from U.S. federal and state district, appellate and supreme courts in results returned by Google Scholar. In addition to each case, Google also returns citations of that case in other opinions. This service is unlikely to put West Publishers or Lexis Nexis out of business, but it does make it considerably easier for the average person (or researcher) to find these cases.
