RelFinder - Visual Data Web

RelFinder - Visual Data Web
Are you interested in how things are related with each other? The RelFinder helps to get an overview: It extracts and visualizes relationships between given objects in RDF data and makes these relationships interactively explorable. Highlighting and filtering features support visual analysis both on a global and detailed level. The RelFinder is based on the open source framework Adobe Flex, easy-to-use and works with any RDF dataset that provides standardized SPARQL access. Check out the following links for some examples: The RelFinder can easily be configured to work with different RDF datasets. The RelFinder can also be more deeply integrated with your project: Integrating the RelFinder See the following examples of how the RelFinder is integrated into other projects: Ontotext applies the RelFinder to enable an exploration of relationships in the biomedical domain. All tools on this website are research prototypes that might contain errors.

Ending the Invisible Library To explain the utility of ­semantic search and linked data, Jeff Penka, director of channel and product development for information management solutions provider Zepheira, uses a simple exercise. Type “Chevy Chase” into Google’s search box, and in addition to a list of links, a panel appears on the right of the screen, displaying photos of the actor, a short bio, date of birth, height, full name, spouses and children, and a short list of movies and TV shows in which he has starred. Continue typing the letters “ma” into the search box, and the panel instantly changes, showing images, maps, current weather, and other basic information regarding the town of Chevy Chase, MD. The panels are powered by Google’s Knowledge Graph, a massive knowledgebase that launched in May 2012 with “more than 500 million [data] objects” drawn from sources including Freebase, Wikipedia, and the CIA World Factbook, “as well as more than 3.5 billion facts about and relationships between these different objects.

Interactive: Mapping the World's Friendships Technology bridges distance and borders. Individuals today can keep in touch with their friends and family in completely new ways — regardless of where they live. We explored these international connections through Facebook and found some trends — some predictable, some wholly unexpected, and some still inexplicable. Who can explain the strong link between the Democratic Republic of Congo, one of the poorest countries in the heart of Africa, and Ecuador? rdf4h-0.9.1 'RDF for Haskell' is a library for working with RDF in Haskell. At present it includes parsers and serializers for RDF in the N-Triples and Turtle, and parsing support for RDF/XML. It provides abilities such as querying for triples containing a particular subject, predicate, or object, or selecting triples that satisfy an arbitrary predicate function.

gFacet - Visual Data Web Complex semantic querying made easy! gFacet is a new approach to explore RDF data by combining graph-based visualization with faceted filtering techniques. The facets are represented as nodes in a graph visualization and can be interactively added and removed by the users in order to produce individual search interfaces.

Linked Data OCLC has been working with Linked Data for several years. As can be seen from the publishing of the Dewey Decimal Classification (DDC), the Virtual International Authorities File (VIAF) and Faceted Application of Subject Terminology (FAST) as linked data. The release of experimental WorldCat Linked Data in June 2012 was another milestone in the exposure of bibliographic metadata as linked data. The OCLC linked data strategy is an evolving mix of Linked Open Data (LOD) and Linked Enterprise Data (LED). This means that we will have incremental releases of new data and services, as we better understand how to model and publish the information. The next step on this evolutionary journey into linked data is the production release of WorldCat Works; the first entity in a series of WorldCat linked data releases.

NameBase NameBase is a web-based cross-indexed database of names that focuses on individuals involved in the international intelligence community, U.S. foreign policy, crime, and business. The focus is on the post-World War II era and on left of center, conspiracy theory, and espionage activities.[1] In the 1980s, through his company Micro Associates, he sold subscriptions to this computerized database, under its original name, Public Information Research, Inc (PIR).

RDFa 1.1 Distiller and Parser Warning: This version implements RDFa 1.1 Core, including the handling of the Role Attribute. The distiller can also run in XHTML+RDFa 1.0 mode (if the incoming XHTML content uses the RDFa 1.0 DTD and/or sets the version attribute). The package available for download, although it may be slightly out of sync with the code running this service. If you intend to use this service regularly on large scale, consider downloading the package and use it locally. Storing a (conceptually) “cached” version of the generated RDF, instead of referring to the live service, might also be an alternative to consider in trying to avoid overloading this server…

RDFScape : Home Page RDFScape is a project that brings Semantic Web "features" to the popular Systems Biology software Cytoscape. It allows to query, visualize and reason on ontologies represented in OWL or RDF within Cytoscape. A full list of features is reporte in Features. Unlike other ontology-based features in Cytoscape, RDFScape doesn't consider ontologies as annotation, but as a knowledge-base that can be interpreted through standard inference processes and through custom inference rules. The result is that ontologies can be interpreted for specific analysis needs.

Tabulator: Generic data browser The Tabulator project is a generic data browser and editor. Using outline and table modes, it provides a way to browse RDF data on the web. RDF is the standard for inter-application data exchange. You can use it in two ways As a Firefox Add-on The tabulator extension is a Firefox extension which allows Firefox to handle data as well as documents.

HCLSIG/LODD/Data LODD-related datasets that the LODD group already made available as Linked Data A graph of some of the LODD datasets (dark grey), related biomedical datasets (light grey), related general-purpose datasets (white) and their interconnections. Line weights correspond to the number of links.
