Drupal Government Days: Drupal and the semantic web

Parent article: Drupal Government Days: Drupal and the semantic web

"Let's say that a database lists that a person has had a car insurance since 1967 while the same database lists the person's age as 18 years. Syntactically, there are no errors in the database, but semantically we should be able to diagnose the inconsistency here."

And someone will have to go through and fix the inconsistency - yeah, right. The software will be written to make some kind of semi-educated guess from its Artificial Stupidity engine, and change one of the data to make the database consistent. And all of a sudden, the IRS is knocking on some poor kid's dorm room, asking where his 1040s for 1980-2000 are, since he obviously had enough money to pay for car insurance. Reality will not matter - the computer says, the computer is right, pay up.

We have these problems already with digital maps... errors in any map providers source material will lead to delivery problems in the real world 'cause, well, people are nowadays using navigation systems... this means, no fed-ex, no pizza, no amazon, no nothing anymore.... until all people have updated their navigations software. And yeah... that will happen... in opposite world..

Don't confuse the capability to do inference with the response to the knowledge inferred.

For example, if you own the both system which holds the insurance info and the system that holds the user info, you could use the information to reject entering the inconsistent data in the first place. What you do with it is almost beside the point. The value of having this capability in a way which still allows your systems to be loosely coupled should be fairly obvious.

Only as long as long as someone actually does it. It's like the wonderful world of tagging - great, as long as someone actually *enters* all of the tags on the data, rationalizes and fixes typos, links synonyms in some manner. What people *WILL* do seldom matches what they *should* do.

This "semantic web" stuff is well and good - I just don't think it's really "all that". After all, someone has to actually get around to asking the computer, in the example provided, to check age against length of time holding the policy.

Exactly. The big advantage Google had over Altavista and other early search engines was that they didn't rely on human-entered data descriptions, just raw computer power (and let the user sort it out). Still mostly the same, AFAICS.

Judging myself from some of the example it seems organizations like Google are the primary consumers of this data, they retrieve it, index it, store it and answer questions using it. They have the data and the raw compute power to do interesting things with it should they find a market for the answers.
