The document discusses the work and influence of Professor Rudi Studer in the field of Semantic Web research. It describes how in the mid-1990s, Tim Berners-Lee envisioned developing the World Wide Web into a Semantic Web to allow machines to interpret data. Rudi Studer was one of the first to research topics related to the Semantic Web, driving projects like ONTOBROKER and OIL that resulted in standards like RDF and OWL. By the late 1990s, Rudi had established a research group at the University of Karlsruhe that became seminal for Semantic Web research, with many prominent groups founded by his students or collaborating with his think tank.

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.

12. 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.

13. 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!

This question is similar to the following: “Why were humans not on the moon in the 18th century?“ „ It is the information processing, stupid!“.

44. The theory of the branching Universes Summary

45. 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.

46. 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.
