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
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
A great jump towards the advent of the Semantic Web will take place when a critical mass of web resources is available for use in a semantic way. This goal can be reached by the creation of semantic meta-data in the publication workflow, or by the develop
In this column, Uche Ogbuji completes his introduction to XML and semantics, setting the stage for the more practical columns that will follow. Thinking XML addresses knowledge management aspects of XML, including metadata, semantics, Resource Description
This discussion of XML and semantics kicks off a column by Uche Ogbuji on knowledge management aspects of XML, including metadata, semantics, Resource Description Framework (RDF), Topic Maps, and autonomous agents. Approaching the topic from a practical p
This guide contains links to many RDF resources including examples, documents, software, tools and projects that use RDF, a standard for describing resources on the web.
This Thinking XML column shows how to combine metadata collected from multiple XML source documents into a single Resource Description Framework (RDF) model for effective querying. In this follow-up to his previous installment that introduced how to use X
RDFWeb is intended to be both fun and technically challenging. We hope that at least some of the writing here will be accessible for a general audience, although much of it will be for the rather small community familiar with the subtleties of various Sem
The Semantic Web starts as a simple circles-and-arrows diagram relating things, which slowly expands and coalesces to become global and vast. The Web of human-readable documents spawned a social revolution. The Semantic Web may in turn spawn a revolution
...microformats are (in Alex's words) "adding semantics to markup to take it from being machine readable to being machine understandable." So what use would microformats be in a web browser? Alex explains that microformats will make the Web Browser

Work on the Semantic Web is all to often phrased as a technological challenge: how to improve the precision of search engines, how to personalise web-sites, how to integrate weakly-structured data-sources, etc. This suggests that we will be able to realis
Topics include: Merging Results from Independent SPARQL Queries, Home from SWAP2006, DBin for Power Users to Create Discussion Groups, Use of URIs for Naming, Another Cool Thing About GRDDL, XQuery and RDF, Dark Side of the Semantic Web, CSS in RDF+, QOT
We believe that the enterprise ontology will become a cornerstone in many information systems in the future. In general terms, an ontology is an organization of a body of knowledge or, at least, an organization of a set of terms related to a body of know
I will discuss how RSS and its taxonomy module can be used as a central format to carry metadata collected in a classical news format, such as XMLNews-Story, to RDF or relational databases and XML Topic Maps. Readers should have basic familiarity with RSS
From legacy relational databases to the semantic web, the China Academy of Traditional Chinese Medicine (CATCM), where over 70 legacy relational databases are semantically interconnected by an ontology with over 70 classes and 800 properties, providing in
In this article, I will discuss how RSS 1.0 and its taxonomy module can be used as a central format to carry metadata collected in a classical news format, such as XMLNews-Story, to RDF or relational databases and XML Topic Maps. Readers should have basic
Ontologies play a prominent role on the Semantic Web. They make possible the widespread publication of machine understandable data, opening myriad opportunities for automated information processing. However, because of the Semantic Web's distributed natur
"Many people have told me this week that they think 'Web 2.0' has not been very impressive so far and that they really hope for a next-generation of the Web with some more significant innovation under the hood -- regardless of what it's called. A lot of p
some time now, I’ve wanted to increase my understanding of microformats. If you’re unfamilar with the term or want to understand the basic purpose of this technology better, I suggest reading Phil Windley’s Microformats: Paving the Cowpaths. I read
Web 2.0 is a vision of the web where content and functions can be remixed and reused to create new content or new applications. Web services and the semantic web are two of the key enablers for this vision but there appears to be dual approaches to both
