<p class="MsoNormal" style="MARGIN: 0in 0in 0pt"><font face="Times New Roman">I think I haven't elaborated the problem properly. In hypothetical levels, if you compare knowledge modeling in children, they are able to grasp concepts (more declarative) quickly because their knowledge networks are small in scale. However, with their development, they start to inference based on their existing knowledge and selectively attend to things. Again, since the existing knowledge networks are getting bigger and bigger, these agents should become inefficient in using their knowledge effectively as a whole. In this effort, I see some people are more reluctant in absorbing changes to whatever they believed earlier even they wanted to do so (may be because of knowledge conflicts at cognitive levels). I see this as one major problem which creates differences between generations.</font></p>

<div> I am curious what examples of such problems you think you have observed in aged people. It does not seem to me that ontological relations are likely to change over time, as contrasted to things like ideas about what things should cost.</div>

<p style="MARGIN: 0in 0in 0pt"><font face="Times New Roman">Recently when I was thinking about dynamic ontology modeling, I got the perception that there should be a growing aging problem associated in such models. The reason is that when the network grows over the time, the concepts should be from a spectrum of time frames from past to present. If such a model is used for future decision making, there should be a possibility that the decisions are bit outdated for the current time. I have seen this problem in many aged people.</font></p>
