   Applications of Analogical Reasoning Systems (WAS RE: [xml-dev] XML-base

[ Lists Home | Date Index | Thread Index ]

Something else to consider.  I've been reading Tim Bray's 
excellent blogs on searching.  Sowa makes much of analogical 
means to detecting similarities.

1.  Can analogical systems be used as adjuncts to search 

2.  Given the position Tim seems to be taking that search 
engines don't get much bang for the buck out of some approaches 
to improving search results (using Google as the example), 
does the mean that the Semantic Web doesn't offer much that a 
search engine really needs, or is it the case that whereas 
a user searching the web gets little benefit, other applications 
would?  What would these other applications be?

Sowa makes much of the use of analogical reasoning as a means 
to create and then select among theories to apply to a situation? 
We make much here of "lessons learned" but these are in effect, 
"theories we apply" before we attempt to use logical means to 
argue our case.   So perhaps one application is as a means to 
support argumentative debate by having a system that can look 
at cases and find precedents.  Legal systems could use that. 
Another might be analysis of written works (lists and blogs 
come to mind) and look for similar positions taken for comparison 
to historical results.  This becomes the "protect against what 
we know that just ain't so" system.

Such a system might require loose searching then benefit by 
automated analysis that uses an analogical reasoning engine 
to sift and find the most relevant cases, then illustrate 
point for point comparison with results summarized.

1. Search for precedent cases.
2. Create theories.
3. Select among the best theories offered.
4. Create the case.

Consider the thread started originally with a poor filtering 
engine for finding "bad words" or "bad sites".  Such systems 
probably use word and site lists, but do not do word sense 
analysis or make cases for the classification.  If a policy 
maker acted on these, they would also have to make the case.
