Intelligent Content
End-User
Intelligent Content
Content which does
contain the words
the user asked for
Extractor Agents
+
Content which does not
contain the words
the user asked for, but
is about what he asked
for.
Value-added Metadata
+
Content the user did not
think to ask for, but
which he needs to
know.
Semantic Associations
Semantic Associations

Knowledge Discovery - Example

(USGS, NEIC)
(Oklahoma Observatory, etc.)
Nuclear Test May Cause Earthquakes
Is it really true?
Complex Relationships
A nuclear test could have caused an earthquake
if the earthquake occurred some time after the
nuclear test was conducted and in a nearby region.
NuclearTest Causes Earthquake
<= dateDifference( NuclearTest.eventDate,
Earthquake.eventDate ) < 30
AND distance( NuclearTest.latitude,
NuclearTest.longitude,
Earthquake,latitude,
Earthquake.longitude ) < 10000
Knowledge Discovery - Example
When was the first recorded nuclear test conducted?
1950
Find the total number of earthquakes with a magnitude
5.8 or higher on the Richter scale per year starting from 1900
Increase in number of
earthquakes since 1945
Knowledge Discovery - Example…
For each group of earthquakes with magnitudes in the ranges
5.8-6, 6-7, 7-8, 8-9, and >9 on the Richter scale per year
starting from 1900, find average number of earthquakes
Number of earthquakes with
magnitude > 7 almost constant.
So nuclear tests probably only
cause earthquakes with
magnitude < 7
Knowledge Discovery - Example…
Find pairs of nuclear tests and earthquakes such that the earthequake
occurred within 30 days after the test was conducted and in a radius of
10000 miles from the epicenter of the earthquake
