"The Semantic Web is not a separate Web but an

extension of the current one, in which [data] is given

well-defined meaning, better enabling computers and

people to work in cooperation.“

CONCLUSION

27

I-Semantics 2013

9th International Conference on Semantic Systems

Traditional publishers will survive if they

Leverage open data as much as possible;

Leverage structured data to provide new functionality to

consumers;

Leverage software to generate new structured data from

unstructured data (e.g. text);

Be aware that traditional publishers are no longer your

main rivals;

Promote innovation by

— Enabling employees to explore new technologies and

concepts;

— Having a group dedicated to innovation; and

— Having hackathons.
