How the Semantic Web Will Change Information Management: Three Predictions

I have doubts about “the wisdom of the crowd” as promoted by various writers on social networking tools. But I have no such reservations when it comes to the enhanced wisdom of smaller groups of connected individuals. Yes, ‘two heads are better than one’ often, and three, four or more can be even better in the right circumstances.

In my Knowledge Architecture workshop which I run for Aslib, I make sure that delegates hear me talk for five or so minutes about the Semantic Web (SemWeb, or Web 3.0 if you must), and in particular the role which ontologies will play. I do this by showing them a block diagram (above right) of the structure of the SemWeb as devised by the W3C. But now, I realise that it’s just not enough to describe the structure, and that I need to explain how it will fundamentally change how we can access Web-based information.

ISKO UK member Silver Oliver has recently had an article published in Freepint’s FUMSI network with the title I have used for this post. Despite the millions of words which must have been written to explain what the SemWeb is about, Silver’s explanation is the best account I have yet come across of how SemWeb KO techniques will change our approach to information management.

Read it – or regret it! I’ll certainly be including a reference to Silver’s article in future runs of my workshop.

Sharing Vocabularies on the Web via SKOS

June 18, 2008

The effectiveness of the Semantic Web (SemWeb) will be heavily dependent on the ability of computers to reason and communicate using controlled vocabularies. When the SemWeb arrives, it will have an impact on all users and designers of Web-based systems, Internet and intranet alike. Since SKOS (Simple Knowledge Organization System) will underlie so much SemWeb functionality, it’s in the interests of everyone who designs or uses knowledge organization systems to know about it.

SKOS is the name given to a family of standards being created to express the semantic structure of controlled vocabularies (thesauri, classifications, subject headings etc.) so that they can be accessed and interpreted by programs and services. As a draft Web standard, SKOS Reference provides a data model that can be used as a vehicle for the development, use and sharing of knowledge organization systems across information sectors and within the Semantic Web framework.

Aware of the growing importance of SKOS, the British Chapter of the International Society for Knowledge Organization (ISKO UK) in cooperation with the School of Library, Archives and Information Studies at UCL has invited a group of experts to introduce this standard, explain its status, potential and scope. Our speakers are involved in the development and application of SKOS and related standards and are hoping to provoke some interesting discussion.

Members of the W3C Semantic Web Deployment Working Group, Alistair Miles and Antoine Isaac will explain the role of SKOS in the Semantic Web, the ideas behind SKOS and the way it is intended to function. The convenor of BSI committee IDT/2/2/1 Stella Dextre Clarke and collaborators Leonard Will and Nicolas Cochard will discuss the data model of the recently developed BS 8723 standard known as DD8723-5, focusing on its relationship with SKOS and interoperability issues. Ceri Binding and Douglas Tudhope from University of Glamorgan will present their AHDS-funded Semantic Technologies for Archaeological Resources project, raising issues for practical applications of SKOS and SKOS-based terminology web services.

This event, the third in ISKO UK’s KOnnecting KOmmunities series, promises a fascinating glimpse of the future of controlled vocabularies. No one involved or interested in the development, management or implementation of controlled vocabularies can afford to miss it.
