Using Emergent Classification as a Starting (Not End) Point.

http://www.adaptivepath.com/publications/essays/

From elearningpost comes mention of this useful article by Peter Merholz (some may remember him from 'peterme' days, one of my earliest regular blog reads).

D'Arcy, King and I had been trading emails a few weeks back on the value of emergent classifications systems like those seen in Flickr for use in learning object repositories. Clearly, the idea is getting a bit of play, at least within the blogosphere.

What troubled me was that some of the current executions seemed a little bit like a baby/bathwater thing - yes, emergent classification systems are interesting and reflect actual users' language usage, but they are also problematic - in being flattened, they do not have the depth (and the corresponding teaching ability) that hierarchical taxononmies can offer their users, and are also plagued with some of the problems Merholz points to. I mean, have you ever actually tried to find something you know should be there but didn't know the classification for, (as opposed to just serendipidously browsing), in an flattened keyword system?

Instead, I think Merholz describes better than I did in my emails to D'Arcy and King what I think we should be looking towards - using 'emergent' temrs as the basis for creating connections between terms users actually use, as the basis for continual refinement of more complicated, less flattened, taxonomies.

How would this actually work - at the very least I think it could show up in things like 'type ahead' functionality that tries to complete the term you are entering based on previous 'emergenet' terms, or else asking the user to confirm whether they were using a term in one sense or another after they have submitted their choice. - SWL[EdTechPost] -- I think you are missing the power of search cimbined with usage information - the google way to usefulness - is a workable organic model that maps human behavior with some extra facilitation with classifications/hierarchies of links.  The place where cogent hierarchies will work is in personal search bots that to a degree map the hierarchial category structure of the human for whom the search is being performed.  A server system can only go so far with "common language" that is necessarily built on past usage of a shared language such as English.  -- suggestion: keep the xml-rpc gateway open for assisted searching because the user's machine is the proximal client. -- BL

Digital Cameras Help Alert Sleepy Drivers [Slashdot:] Home > News, Guides, Tips > Digital Cameras Appropriated for Automobile Safety - Help Deter Distracted Drivers

Digital Cameras Appropriated for Automobile Safety - Help Deter Distracted Drivers by Emily Raymond October 19, 2004 -" Digital cameras are now being used in cars to keep drivers awake and less distracted. The cameras are used as part of the automotive vision system; some cameras scan drivers’ eye movements to detect where the driver is looking, while others watch the road for animals or pedestrians. If a pedestrian crosses the street in front of a car with the automotive vision system, the digital cameras will see the person and scan the driver’s eyes to check for alertness. If the driver is not paying attention, an alarm will alert the driver. According to a study by the National Highway Traffic Safety Administration, about 25 percent of all automobile accidents and 68 percent of rear-end crashes are caused by distracted drivers. ...Despite the fact that the use of a cell phone while driving can increase chances of an accident by 400 percent, many drivers continue to chat the miles away."

Northern Illinois University Students evaluate professors on Web - Desiree Smith - Northern Star. NIU recently signed up with PickAProf.com, a Web site that allows students to “grade� their professors at any time throughout the semester. Students can now submit written reviews about any teacher on campus. PickAProf.com’s professor reviews are the [Online Learning Update] -- there are serious biases in the simple use of student ratings such a physical attractiveness of the professor according to the scientific literature on this topic -- BL

Yesterday, talking with Marcus Mauller, we figured out how to integrate BitTorrent with Manila. The key is to do it through Gems. In a special Manila site on a server running the BitTorrent software, when you upload a Gem to that site, it automatically generates a meta file, and links to it in the Gems table listing. It's the perfect user interface. The content creator needs to know nothing about the difficult process of Torrent-izing a media file, the URL is handled the same way the non-Torrent URL is handled.
