Course Description

In this course you will learn what the Semantic Web and Linked Data are, and what these technologies enable. You will be introduced to many useful Semantic Web languages and tools. Finally, you will gain a broad understanding of the most challenging problems and what progress has been made towards solving these problems.

Readings

Your readings will be listed below as they are assigned. Readings marked SWP are from our textbook, "A Semantic Web Primer." We will also read research papers and technical specifications, and I provide links to online versions of these documents. Usually this is in HTML or PDF format, although a few papers may be in PostScript or Compressed PostScript format. Also, each online reading assignment is followed by a reference (in brackets) that links to the complete citation for the paper. The citations for the entire reading list can be found here.
