Hasso Plattner Institute (HPI) reports high interest worldwide in the latest online course at its new open online Internet educational platform
. Already more than 3,000 have signed up for the third course starting on
. The course, which will guide participants through the Semantic Web, is free of charge. Registration is still possible. Those who successfully complete the course will be rewarded with a certificate from HPI.
"The conventional Internet search reaches the limits of its power when the computer is expected to correctly interpret the meaning of information and not simply a character string. How the information expressed in natural language is extended in the so-called Semantic Web to enable a machine-readable interpretation of its meaning - semantics - is what we would like to show course participates", said course instructor Dr.
, senior researcher in the HPI research group Internet Technologies and Systems.
"Semantic web technologies enable the retrieval of information and the search for it in a more precise and comprehensive way," Sack added. "Previously scattered and heterogeneous data can be mapped based on formal common knowledge - ontologies - and thus combined together," said the Potsdam scientist.
The course will initially deal with the basic architecture of the Semantic Web and then focus on the representation of knowledge and logic. Subsequently, the fundamentals of description logics and the Web Ontology Language (OWL) based on it are examined. Finally, applications in the "Web of Data" will be treated. Key terms include: ontological engineering, knowledge discovery, linked data and semantic search. According to HPI, for successful participation it is necessary to have a basic knowledge of the principles of logic, an understanding of Internet technologies and a fundamental knowledge of database technologies.
