Reference: “Triple Stores Aren’t”
Posted by admin in Infrastructure, Tools on August 7th, 2009
…
Is there anything harmful with the misnomerization of “triple”, enough for the community to try their best to start talking about “tuples”? I think there is. Linked Data is the best example of how a focus on the three-ness of triples can fool people into sub-optimal implementations. I heard this fear expressed several times during the conference, although not in those words. More than once, people expressed concern that once data had been extracted via SPARQL and gone into the Linked Data cloud, there was no way to determine where the data had come from, what its provenance was, or whether is could be trusted. He was absolutely correct- if the implementation was such that the raw triple was allowed to separate from its source. If there was a greater understanding of the un-three-ness of real rdf tuplestores, then implementers of linked data would be more careful not to obliterate the id information that could enable trust and provenance. I come away from the conference both excited by Linked Data and worried that the Linked Data promoters seemed to brush-off this concern.”

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.”
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.

NSDL Releases EduPak: An Open Source Digital Library Services Platform for Education
Posted by admin in Library World, Tools on March 31st, 2009
NSDL EduPak 1.0 is a publicly available, lightweight version of NCore (http://NCore.nsdl.org), established in 2008 as an open-source digital library platform of technology and standards that create a dynamic information layer on top of library resources. Based on Fedora open source repository software (http://Fedora-Commons.org), NCore provides users, developers, information managers and decision-makers with systems for description, organization, interrelation and annotation of resources. Built using NCore components, EduPak is an all-in-one, open source, education digital repository solution bundle that provides a general platform for building digital libraries united by a common data model and interoperable applications.
