 Note that real time contexts are typically events and that events are strictly ordered given a simple locale but may overlap given multiple locales so event order is not the only signature. When identifying a situation semantic in an emerging phase, event order is very important but so is proximity of multiple instances of event types. Say you have a system of sensors, you may be tracking the order that these send alerts to determine time and speed of some object. You may also be monitoring multiple sensors and correlating these values. To identify an emergent event and dispatch on warning (roughly analogous to launch on warning), you have to be able to assign force values to the events because the emergence of a situation may be presaged by weak signals in combination with strong signals. Proximity is one of the signals that you monitor given a locale ontology to make a threat assessment. In an intelligence assessment, you may have multiple intelligence types and fusing these into actionable information where the responder assets are limited is the key to effective dispatch. Otherwise, all you are doing is running to false alarms although false alarms are also a key piece of information. Eventually, all of these signals coalesce and are assigned a value from a code list. The tricky bit here is learning to get all of this information from multiple XML streams emanating from different information source types (think HUMINT, OSSINT, SIGINT, etc). If the control is emergent, then it may just be an Xlink type, at least, that is one way to do it. Metadata can be emergent information, in fact, likely is. len From: David Lyon [mailto:david.lyon@p...] On Fri, 2006-06-23 at 09:00 -0500, Bullard, Claude L (Len) wrote: > http://hbsworkingknowledge.hbs.edu/item.jhtml?id=5387&t=finance > > Note the emphasis on preparing contexts for real time decisions and > remember the discussions we've had about emergent controls for > selectors, and the emphasis on locale as a situated semantic set. > Locale becomes an identifier for an ontology of situation types. Hi Len, Interesting.. being off-list for a while I missed some of the discussions. but your point is right... I'll share a little story... A friend of mine works for a stock-broking company. He was saying that even stock exchange transactions are masked these days by real-time systems. You can mask transactions by splitting a large chunk of shares into smaller pieces, send them to Europe or HK, let people buy a few... watch the prices go up... sell the rest of the parcel... let it all fizz... see the price come back to normal... and bang you've made a profit... above the normal profit that would have made with a large parcel sale... Now I don't know if this has anything to with what you are talking about but it goes to show how much things have changed in the world.. Lots of things are a real-time game... and it is interesting to watch some people doing things with the x-boxes or ps-2s and some with their stock-xchg-boxes... I'm quite sure there is some fun left to be had in xml... guess it is just a matter of finding it..... David
