Google Rolls out Semantic Search Capabilities
“Google has given its Web search engine an injection of semantic technology, as the search leader pushes into what many consider the future of search on the Internet.”
Library of Congress Embraces Linked Data Movement
Library of Congress Embraces Linked Data Movement
See in particular:
Which describes itself as:
“This site serves as a placeholder for forthcoming web services that will enable both humans and machines to programmatically access authority data at the Library of Congress. The initial services offered are influenced by — and therefore implement — the Linked Data movement’s approach of exposing and inter-connecting data on the Web via dereferenceable URIs. We aim to make resources available on this site within 6-8 weeks. Check this site regularly for more updates as we continue to develop this service!”

JavaScript Information Visualization Toolkit (JIT)
Posted by admin in Tools, User_Interface on April 27th, 2009
The JavaScript Information Visualization Toolkit is an advanced JavaScript infovis toolkit based on 5 papers about different information visualization techniques.
The JIT implements advanced features of information visualization like Treemaps (with the slice and dice and squarified methods), an adapted visualization of trees based on the Spacetree, a focus+context technique to plot Hyperbolic Trees, and a radial layout of trees with advanced animations (RGraph).
Click on the image above to see it in action, then:
- Move the slider on the right to resize
- Drag from anywhere on the circles to relocate
- Click on any label to redraw
- View Source to see JSON expression of data being visualized
This implementation and enhancement of JIT was written by Chris Beer and was demonstrated with a different dataset at Code4Lib this year.
The dataset being demonstrated here is a slight extension of the one referenced in the Cytoscope post of 2009.04.24.
Yahoo SearchMonkey Includes UMBEL Ontology
+
“…UMBEL is now included as one of the recommended vocabularies for the Yahoo! SearchMonkey service. Using SearchMonkey, developers and site owners can use structured data to enhance the value of standard Yahoo! search results and customize their presentation, including through “infobars“. SearchMonkey is integral to a concerted effort by Yahoo! to embrace structured data, RDF and the semantic Web.”
Large-scale RDF Graph Visualization Tools
Mike Bergman’s selection and review of 26 candidate graph visualization tools. Cytoscape comes in at Number 1.
Cytoscape Graph Visualization Tool
Cytoscape is described as an open source bioinformatics software platform for visualizing molecular interaction networks. However, because of the generic nature of graph display and Cytoscape’s flexible import/export capabilities it can easily be used in many other contexts that involve the visual presentation of a web of connected nodes.
Which, for example, was easily created from nothing more than the following data.

World Digital Library
Posted by admin in Library World, User_Interface on April 22nd, 2009
The World Digital Library (WDL) makes available on the Internet, free of charge and in multilingual format, significant primary materials from countries and cultures around the world.
The principal objectives of the WDL are to:
* Promote international and intercultural understanding;
* Expand the volume and variety of cultural content on the Internet;
* Provide resources for educators, scholars, and general audiences;
* Build capacity in partner institutions to narrow the digital divide within and between countries.
