Part I Colleagues and Historical Roots

A Retrospective on Semantics and Interoperability Research – Bernhard Haslhofer and Erich Neuhold

• Interoperability problems arise when

distinct applications communicate and

exchange information objects with

each other.

• Often the structure and semantics of

these objects is defined by autonomous

designers, each having an individual

interpretation of the real world in mind.

Effectiveness and Efficiency of Semantics

• Provides an excellent analysis of the communalities and differences of

database and Ontology technology in terms of efficiency and

effectiveness.

• Even after more than 30 years of existence, relational databases

remain the mainstay of data archiving because they are the most

efficient way to store, select and access data, particularly if the data

are to be interrelated.

• However they make strong assumptions on how data should be

structured …

• Which makes reuse and interoperability more difficult.

12

Effectiveness and Efficiency of Semantics

• Semantics can add effectiveness to information retrieval without

loss of efficiency.

• Databases implement the aspect of handling data efficiently with a

computer

• Ontologies/semantics implement the aspect of handling data

effectively in order to achieve a certain goal within a certain domain

and resource boundaries.

• Semantic solutions are always put “on top of” database

solutions!

Why then no Space Travels?

• Ants have reached these achievements now for more than about 50

million years

• Humans only for about 10 000 years

• So why ants were not first on the moon?

• This question is similar to the following: “Why were humans not on

the moon in the 18th century?“

• „It is the information processing, stupid!“.

The theory of the branching Universes Summary

www.sti-innsbruck.at

The RudiUniverse

• In the mid 1990s, Tim Berners-Lee had the idea of developing the

World Wide Web into a „Semantic Web“,

• a web of information that could be interpreted by machines in order

to allow the automatic exploitation of data, which until then had to be

done by humans manually.

45

www.sti-innsbruck.at

The RudiUniverse

• One of the first people to research topics related to the Semantic Web

was Professor Rudi Studer.

• From the beginning, Rudi drove projects like ONTOBROKER and OIL,

which later resulted in W3C standards such as RDF and OWL.

• By the late 1990s, Rudi had established a research group at the

University of Karlsruhe, which later became the nucleus and breeding

ground for Semantic Web research, …

• … and many of today’s well-known research groups were either founded

by his disciples …

• or benefited from close cooperation with this think tank.
