Today’s commercial realizationof Semantic Web

TaaleeSemantic EngineTM

Taalee’s Intelligent Content Process

Content which doescontain the wordsthe 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.

Nuclear Test May Cause Earthquakes

Is it really true?

Complex RelationshipsComplex Relationships

A nuclear test could have caused an earthquakeif the earthquake occurred some time after thenuclear 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 - ExampleKnowledge Discovery - Example

When was the first recorded nuclear test conducted?

Find the total number of earthquakes with a magnitude5.8 or higher on the Richter scale per year starting from 1900

1950

Increase in number of earthquakes since 1945

Knowledge Discovery - Knowledge Discovery - Example…Example…

For each group of earthquakes with magnitudes in the ranges5.8-6, 6-7, 7-8, 8-9, and >9 on the Richter scale per yearstarting 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 - Knowledge Discovery - Example…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
