LinKBase: World's largest formal medical ontology, i.e. a conceptual computer-understandable representation of medicine. Due to its magnitude, formal structure and the fact that it is machine-readable, LinKBase is the only medical knowledge base capable o
As human language is a primary mode of knowledge transfer, a growing integration of language technology tools into semantic web applications is to be expected. Language technology tools will be essential in scaling up the semantic web by providing automat
This Special Issue of JIME will feature nine papers by invited, internationally renowned authors who have previously written about the effect of technology on education, learning and scholarship. Their interests and writing span distance education, higher
After analyzing a large amount of social annotations, we found that tags are usually semantically related to each other if they are used to tag the same or related resources for many times. Users may have similar interests if their annotations share many
The semantic web must "explain the meaning of words" to computers. Some semantic technologies use a "bottom up" by embedding semantic annotations (metadata) into web content. "Top down" technologies analyze information without metadata using some form of

The Semantic Grid initiative proposes the systematic exporsure of semantically rich information associated with Grid resources in order to build more intelligent Grid services for Grid middleware, services, and applications. Structured semantic descripti
A complex set of extensions to the World Wide Web, the Semantic Web will make data and services more accessible to computers and useful to people. Some of these extensions are being deployed, and many are coming in the next years. This is the only book to
