   RE: [xml-dev] indexing and querying XML (not XQuery)

[ Lists Home | Date Index | Thread Index ]

IF it is really a full-text indexing system,
it scans and infers topics the same way a human 
scans and tags.   It would require a rule base 
perhaps similar to a Schematron assertion engine. 
Past attempts made several passes over content 
to create a series of tagged documents that are 
successively refined.  However, as in memory-based 
patterning systems, the more abstract the links, 
the more opinionated the system.  Such systems 
can become very superstitious in exactly the same 
way people do.  How was it phrased: "A schema is 
an opinion about a document..."

It does sound very interesting. How would it work? What would it look 
like? I have tried doing this with XML Schema but gave up. I had tried 
to use annotations to give weight to different things, then I tried to 
make a type system. For me, it was just easier to write java to handle 
it. Now I write org.xml.sax.ext.DefaultHandler2's that suit my needs. I 
know, not very scalable or user friendly.
