V Geronimenko, Chaomei Chen (Eds): Visualizing the Semantic Web

xabbu — Mon, 18 May 2009 07:34:44 +0000

Mixture of different articles with some background, some technological, some application articles.

Few things I found interesting to keep in mind:

Using Google to test for semantic meaning (by counting hits of statements basically)
Use of P2P technologies for storing semantic data (in the example document & class centric though only)
Aduna, Groxis
Visualizing class links (so where lots of nodes lead to the same node) in a graying out fashion (strong at the class, getting greyed out to the nodes), or in a 3d setting placed out of plane
m-limited force model: to avoid in a spring based placement algorithm the infinite drifting apart, make a cut-off in the repulsive force
In the article “Semantic Association Networks” by Katy Börner: the idea that in the future there will be a knowledge cloud, especially including the scientific world. This will make articles and papers unnecessary, because scientific work would mean to add ‘knowledge nuggets’ or ‘association links’. “A scholar’s reputation would depend on the number of nodes and/or links she or he contributed and their usefulness to humankind.” New nodes could be used to automatically identify redundant information, confirm existing facts, confirm novelty, and point out conflicts. – Interesting picture!

Shelley Powers: Practical RDF

Good O’Reilly book about RDF, RDF Schema, its definition and for what it can be used. Some information also about Ontologies and OWL, but not too much.
As a ‘practical’ book it presents also available tools, but the book is from mid 2003 so this is a bit dated by now.

Thomas B Passin: Explorer’s Guide to the Semantic Web

The book was published in 2004 and it shows – many things are phrased as open questions, but it does give some overview about the topics of the ‘layer cake’, i.e. RDF, Ontologies, Logic/Inference, Trust, in addition speaking about Semantic Web Services & Agents.

Kind of an introduction to the topic, but a bit dated and superficial.

The author also very much likes Topic Maps and always presents them as interesting alternatives, whereas I get the feeling that – at least now – RDF is the standard to go with.
