That looks like a nice tool. I wish the big spreadsheet company (ahem! Microsoft) would work on new innovative features like that!<br /><br />I think your points are correct that systems need to support data exploration better by suggesting operations and visual representations to try. More importantly, the exploration ought to be one in which the human and machine intelligence work hand-in-hand in a mixed initiative way.

I agree wit...Thanks for this interesting blog post. I agree with you on those two challenges. I also see data integration as another major challenge in the long run. I believe that integrated data sets could facilitate having insights that are hard to see by analyzing at data sets in separation. <br /><br />With regard to data import & cleaning, there has been interesting work done by David Huynh in the <a href="http://vimeo.com/10081183" rel="nofollow">Gridworks project</a>. It uses a combination of faceted browsing, visualization & spreadsheet elements to help the user clean a data set.<br /><br />When it comes to supporting flexible visual data exploration, I found in <a href="http://lgrammel.blogspot.com/2010/07/how-information-visualization-novices.html" rel="nofollow">an exploratory user study</a> that tools need to suggest potentially useful visualizations, allow for iterative refinements and provide more learning support. I think that lowering the entry barrier as much as possible is very important, however, this might not be sufficient <a href="http://eagereyes.org/blog/2010/trivialization-for-the-masses" rel="nofollow">if people are reluctant to "invest time in open-ended, ill-defined tasks"</a>. I am currently working on <a href="http://code.google.com/p/choosel/" rel="nofollow">Choosel</a>, a web-based visualization environment that explores some of those ideas.Anonymoushttps://www.blogger.com/profile/09802741785717077341noreply@blogger.comtag:blogger.com,1999:blog-4999686744433629981.post-81999605636664524102010-09-03T03:38:23.763-07:002010-09-03T03:38:23.763-07:00Google Map has done a great job in helping create ...Google Map has done a great job in helping create better map-based visualizations. But even then, not everything is easy. If I want a map of Europe, with major flight connections from North America highlighted, it's not simple. End-user visualization mashups like this are still just too difficult.<br /><br />I want a visual analytics system that's like what spreadsheet did to numbers. It should be simple to cut and paste flight connections into, say, a table in the system, and then I would like to say, 4please visualize this on a map."Ed H.

I do, however, agree completely that supporting casual, but useful, interactions with data sets (which I think is part of what you're getting at) is a key challenge.<br /><br />Some of the great stuff available through time series manipulations (sliders for the "current time", increasing/decreasing the frame size, etc.) and in geovisualizations (simple layering and filtering, contextual zoom to selected targets) make it easy for lay people to use the visualizations and even contribute meaningfully, even if for only their own edification.<br /><br />I would say that, yes: we don't need more new visualizations, but that we need to instead move in the directions advocated by MacEachren (in geocollaboration): Support the simple manipulation of visualization frameworks by non-experts. We see this behaviour every day in map use, we just need to expand it to work in more visualization domains.Smartbottomhttps://www.blogger.com/profile/10289832390084738833noreply@blogger.comtag:blogger.com,1999:blog-4999686744433629981.post-50696391821147494372010-08-23T15:46:36.040-07:002010-08-23T15:46:36.040-07:00mark: The whole area of learning psychology is hug...mark: The whole area of learning psychology is huge, and I only know the surface. I mentioned Piaget really in the context of the idea of schema theory, which is a learning theory that posits that the representation of the ideas in a person's head is an organized network of mental structures.<br /><br />See:<br />http://www.sil.org/lingualinks/literacy/implementaliteracyprogram/schematheoryoflearning.htm<br /><br />I know less of Piaget's work in child development, although that's a topic of interest to me. Piaget's ideas seems to have influenced RC Anderson's work on Schemata.<br /><br />It is interesting to think about whether shared representations within social contexts leads to inability to jump out of fixed solutions. Hence my comment about "Groupthink can be dangerous precisely because it tends to do assimilation instead of accommodation."<br /><br />EdEd H.

Even the title of your blog post suggests that if I add a hashtag, my post is more likely to get retweeted -- but what we're really seeing here is more a correlation.<br /><br />The nice thing about retweets is that they give us a nice proxy for how much someone values a tweet. I wonder how much overlap there is with a feeling of "I'm glad I saw this!", and what it might not capture?

Taking aggregate statistics indicates trends in what people are doing, but doesn't negate that.<br /><br />There is already some persuasive evidence that some Wikipedia entries are curated by paid for authors (they try to hide that of course), outright edit wars are not uncommon and decisions (open to hostile interpretation) to only allow some people to edit certain entries happen.<br /><br />So it's already biased. As anybody who has made their first wrong decision based on Wikipedia wrongness will be all too aware.<br /><br />So, I believe, some have been "feeling proprietorial" about their entries for years. Others don't. Will "ownership feelings" increase? I imagine so as the less principled parts of society get more involved.<br /><br />For an individual starting an entry, I reckon, it's a good idea to shed any vestige of ownership the moment you publish.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4999686744433629981.post-34079198814066511482010-06-18T16:54:55.360-07:002010-06-18T16:54:55.360-07:00@Joe: I remember reading about generative platform...@Joe: I remember reading about generative platforms in that article. Ideas have indeed become more social. Our group has been recently looking into understand information diffusion models, which does seem to take on more generative flavors.<br /><br />@Jon: Models are a proposal for saying what we might understand about the data underneath. They are most definitely wrong in one way or another. After all, Newton was sort of wrong until Einstein corrected parts of it, and even Einstein's models are not a complete description of the real world. It doesn't make Newton's work or Einstein's work pseudo-science.<br /><br />@randall: I wasn't so much trying to place everything into neat little piles, as much as offering a way to think about the kinds of models we might want to build. Indeed, in the talk, I mentioned how some models are both explanatory and predictive and generative all at the same time. It does not necessarily mean the models are more useful the more categories they cover, however.Ed H.

(there has, of course, been a lot of ink spilled in the philosophy of science and the philosophy of social science about the proper connections between these various functions that a model might serve---but, as i said at the top, it's not clear to me whether getting clear on that is important for your talk or not.)<br /><br />all the best.randallhttps://www.blogger.com/profile/02572983020113458581noreply@blogger.comtag:blogger.com,1999:blog-4999686744433629981.post-73550084688592611192010-06-15T20:26:06.825-07:002010-06-15T20:26:06.825-07:00I've seen so much Wiki-Phrenology over the las...I've seen so much Wiki-Phrenology over the last 10 years that it keeps flashing me back to the days when that phamous phrenology pic appeared on the cover of just about every other cognitive psych book that came out.<br /><br />The picture worth a thousand cautionary tales was of course a way of reminding ourselves that pertinent data collection and precise theory both depend on a thorough familiarity with the relevant factors in the domain of interest.<br /><br />Deja vu all over again …Jon Awbreyhttp://mywikibiz.com/Directory:Jon_Awbreynoreply@blogger.comtag:blogger.com,1999:blog-4999686744433629981.post-70615619427984118722010-06-15T08:54:01.289-07:002010-06-15T08:54:01.289-07:00Great presentation - thanks for sharing the slides...Great presentation - thanks for sharing the slides, and some explanatory notes about some of the themes.<br /><br />Your discussion of "generative models" reminded me of some of the points that Tim O'Reilly has recently been making about "generative platforms" in <a href="http://opengovernment.labs.oreilly.com/ch01.html" rel="nofollow">open government</a> (Gov 2.0) and other areas where participatory platforms can promote real change, a theme that was sparked by Jonathan Zittrain's book, <a href="http://futureoftheinternet.org/" rel="nofollow">The Future of the Internet ... And How to Stop It</a>.<br /><br />One of Tim's observations, in particular, harks back to your early point about all models being wrong (or shown to be wrong eventually, as more data and/or new insights become available): "open, generative systems eventually become closed over time, losing their innovative spark in the process".<br /><br />Given the rapid pace of innovation in social computing, I imagine the most we can hope for are iteratively generative models (and platforms).Joe McCarthyhttp://gumption.typepad.comnoreply@blogger.comtag:blogger.com,1999:blog-4999686744433629981.post-35058627334852011492010-05-03T22:26:57.002-07:002010-05-03T22:26:57.002-07:00This comment has been removed by a blog administrator.Amitnoreply@blogger.comtag:blogger.com,1999:blog-4999686744433629981.post-48357031371677505802010-04-29T09:54:37.755-07:002010-04-29T09:54:37.755-07:00@Joe: Thanks for the pointer to EdgeRank.
