SMOB - Semantic MicroBlogging

  • SMOB is a distributed / decentralised microblogging system
    built on RDF and Semantic Web technologies, mainly
    SIOC and
    FOAF. Currently, we have
    simple prototypes of a publishing and an aggregating service, less than 100
    lines of PHP code each.

Applying SKOS Concept Schemes

  • The problem with OWL is that it is a more complicated technology than many people can handle, at least initially. New tools and books are emerging to help lower the bar to OWL modeling, but there remains a need to satisfy the requirements for traditional knowledge management schemes and workers. This article introduces the kinds of data that has been produced so far and how the Simple Knowledge Organization System (SKOS) helps support lightweight but still relatively formal concept schemes.

RDF Vocabulary Description Language 1.0: RDF Schema

  • This specification describes how to use
    RDF to describe RDF vocabularies. This specification defines a vocabulary for
    this purpose and defines other built-in RDF vocabulary initially specified in
    the RDF Model and Syntax Specification.

http://swui.semanticweb.org/swui06/papers/Karger/Pathetic_Fallacy.html

    • In the arts, the

      pathetic

      fallacy
      is the act of ascribing human feelings to inanimate objects. 

      We argue that the same fallacy is turning up on the semantic web---that

      researchers are (perhaps subconsciously) allowing the computer's internal

      representation of data to influence the way their tools present information to

      users, when instead they should developing interfaces that are based on the

      users' needs, independent of the computer's particular information

      representation.





      In the following discussion, we will look at some examples of the pathetic

      fallacy in terms of the interaction challenge of



      • what knowledge these graphs communicate,



      • what tasks they support, and



      • whether these are the optimal paradigms for such communication and tasks.





      From this context, we investigate two questions:  Are graphs the right

      default representation for the Semantic Web?  And if not, how

      might we think about default presentations for the Semantic Web in order to

      make accessible its promised benefits for knowledge building and sharing?

Where to Find Open Data on the Web - ReadWriteWeb

  • A lot of data sources are already freely available on the net, as it turns out, if you just know where to look. Here's a summary,

Is This The Future Of Search?

  • This new video, however (also recorded by Pike), shows the full Google search experience with a very Digg-like interface. Users vote search results up or down - a down vote makes it dissapear with a “poof,” an up vote moves the result to the first page.

alphaWorks : Scalable Highly Expressive Reasoner : Overview

  • Scalable Highly Expressive Reasoner


    A technology that provides ontology analytics (OWL-DL without nominals) over highly expressive ontologies.

index [MOAT]

  • MOAT (Meaning Of A Tag) provides a Semantic Web framework to publish semantically-annotated content from free-tagging.

Dapper: Frequently Asked Questions

  • Dapper is a free, web-based service that allows you to extract and use
    information from any website on the Internet. It allows you to create a
    "feed" (which we call a Dapp) for any site without programming. You can
    then use these feeds in a variety of ways: as an RSS feed, a widget,
    in Facebook applications, and more (and if you're a programmer, you can
    incorporate them into your applications and websites).

Associating Resources with Namespaces

  • This Finding addresses the question of how ancillary information (schemas,
    stylesheets, documentation, etc.) can be associated with a namespace.

OWL restrictions

  • This document is intended for people starting to use OWL, the W3C
    Web Ontology language [OWL Overview] and
    who are puzzled about how OWL constructs work, in particular OWL
    restrictions. In the
    course of this note we also discuss some basic ontology-engineering
    principles.

The Linking Open Data dataset cloud

  • This image shows some of the datasets published in the
    Linking Open Data community project. Clicking any of the
    datasets will take you to its project homepage.

Main Page - Neurocommons

  • The Neurocommons project seeks to make all scientific research
    materials - research articles, annotations, data, physical materials - as available and as useable as they can be.
    We do this by both fostering practices that render information in a form that promotes uniform access by computational agents - sometimes called "interoperability". We want knowledge sources to combine meaningfully, enabling semantically precise queries that span multiple information sources.

    Our work covers general data and knowledge sources used in computational biology as well as sources
    specific to neuroscience and neuromedicine.
    The practices that we develop and promote are designed to play well on the Semantic Web. We view our technical work not as creating a new service or content library, although we do both, but rather as helping to promote the growth of semantically linked scientific information.

URI documentation protocol - Neurocommons

  • How should one go about finding documentation that will explain what a URI names, in cases where this is needed and it is not already at hand? HTTP was not designed to help out here, so the following is not as elegant as would be a protocol designed with this in mind.

    If you're doing bulk processing of URI documentation, you may be better off doing bulk downloads or SPARQL queries on an appropriate SPARQL endpoint, as large numbers of probes will be inefficient and will load servers, usually unnecessarily.

    The following protocol is designed to be forgiving enough to grandfather many URIs already in use on the Semantic Web, such as those in the RDF Schema vocabulary and Dublin Core, while strict enough to support our URI requirements. It coincides with HTTP in the absence of overrides, responses containing a Location: header, and 200 responses.

Extension:Semantic Forms - MediaWiki

  • An extension, based around Semantic MediaWiki, that allows users to create forms for adding and editing pages that use templates to store semantic data. Forms are defined using editable text files, written in a custom markup language, that are then parsed on-the-fly when a form is needed.

Cofundos.org - community innovation and funding

  • Cofundos helps to realize open-source software ideas, by providing a platform for their discussion & enrichment and by establishing a process
    for organizing the contributions and interests of different stakeholders in the idea.

triplify.org : Overview

  • Triplify is a small plugin for Web applications, which reveals the semantic structures encoded in relational databases by making database content available as RDF, JSON or Linked Data.

SHAME | Overview / Introduction browse

    • SHAME is a library that leverages editors, presentations and query interfaces for resource centric RDF metadata.
      The central idea of SHAME is to work with Annotation Profiles which encompasses:


      • how the metadata in RDF should be read and modified.
      • what input is allowed, e.g. multiplicity and vocabularies to use.
      • presentational aspects like order, grouping, labels etc.

      These annotation profiles are then used to generate user interfaces for either editing, presentation or querying purposes.
      The user interface may be realized in a web setting (both a jsp and velocity version exists) or in a stand alone application (a java/swing version exists).

Cool URIs for the Semantic Web

  • The Resource Description Framework RDF allows you to describe web documents and resources from the real world—people, organisations, things—in a computer-processable way. Publishing such descriptions on the web creates the semantic web. URIs are very important as the link between RDF and the web. This article presents guidelines for their effective use. We discuss two strategies, called 303 URIs and hash URIs. We give pointers to several web sites that use these solutions, and briefly discuss why several other proposals have problems.

Kaivo

  • Kaivo is an information system framework that has currently only a
    partial prototype implementation which I developed in my master's
    thesis. Kaivo supports an architecture for information systems in
    which the data is always kept in a single data model which is RDF.
