Subject: [topicmaps-comment] Everchanging subjects [ Notions haveexistence ...]
Hi Thomas "David, do you see emergence as related to complexity in a topic map (or a set of them), or do you see it as coming out of a simple system, like cellular automata? And if the latter, how do you think that topic maps could fit in?" I do not see a data structure by itself capable of emergence. At the present time topic maps are data structures. and an "external" "engine" is used to do things with them. That is the external engine reads them and creates them, a sloppy metaphor is to say that the external engine "powers them" or ""makes them alive"". (gurk) The engines it seems to me are programmed in such a way as to adhere to or implement the XTM spec. (well in the ideal world the engines do that). I think perhaps that the current engines are not graph processing aware and are more like the steam shovel doing good work only because a skilled operator knows how and when to pull the right levers. (ie activate the right internal routine)) [I fully expect indignation from engine writers. It is not my intention to criticise current engines. What I intend is to point out that the processing done by current engine designs is not situated, nothing more. As Thomas has pointed out there are a myriad applications where "business-programming-headed software" is just fine thankyou. (David agrees. generally)) I think there will be an eventual trend towards having a kind of graph-structure virtual-machine. these gsvm will be able to "process" or "operate" graph structures representing Topic Maps, RDF, DAML-OIL, Conceptual-Graphs, XML technology data structures, graphics graphs(SVG for rexample, maybe VISIO), and so on. Sort of how that 'you know what programming language' has a virtual-machine (but it is not a graph structure oriented processor per se).) TMs They are a graph structure. TMs are not (yet) general graph structures, in my opinion, they are specialized graph structures. Where they are not general graph structures they are not capable of "supporting" certain things. This is why some of the graph structure based operations some people would like to try doing arent possible right now. (I expect more criticism on that.) I do not see how anyone could say that TMs are universal turing machines for example. If they are Id be delighted to be given refernces as to where I can study how to use them that way. By having a graph-structure-processing-aware ""engine"" or (software) processor "running" TM data structures , in the future it will be possible to incorporate/disincorporate other graph structure represented data such as RDF, or DAML-OIL , or CYC. Metaphorically speaking these different graph structures (at the present time) are like the different gauges of railroad track that have been layed around the world. When trains came to a border everybody got out walked across the border andgot on the other train. That's because the tracks were different gauges and a given train could run on only one gauge of track. Also these GSVMs could have subsystems which use techologies such as genetic algorthims, neural networks, fuzzy/rough sets,; which in effect allow the engines to learn the best construction methods and patterns as time passed (learn by doing and observing). This means that with such subsystems that the engines quite potentially could become more efficient with the passage of time/"experience"/"learning". Genetic algorithms for example can allow an engine to examine a number of different structural patterns and ""figure out"" (""evolve"") which is the "best" particular structure for use. (If this sounds like an application of David Dodds' notion of "situated context" you're right). cheers David Dodds PS: Paul Pruett may claim I am wrong about "situated context" being possible outside of special creation fleshbots (humans) but I believe I will demonstrate that he is talking through his hat if he attacks me there. "Situated context" is merely one of the possibilities of *agency*, and frankly only warm pink fuzzy humanists still believe that agency is possible only in a human mind. That is so dreadfully anthropocentric as to be medieval. >From: "Thomas B.
