FW: [ontolog-forum] ANN: http://www.productontology.org - more than 300, 000 specific OWL DL classes for types of objects

I am forwarding the email (just in case you have not seen it) about the "release of http://www.productontology.org, an online-service
that provides valid OWL DL class definitions for all of the ca. 300,000 types of products or services that are contained in the 3.5 million Wikipedia entries."[1]

Meanwhile, I find it interesting to share that, in an immediate email Martin Hepp referred to http://www.productontology.org/#faq4   for the question "How can I fetch a dump file holding all 300,000 class definitions?" and how they "will add filtering techniques so that the dump will only include classes that pass a certain popularity test in RDF datasets."

The dump file at
        http://www.productontology.org/dump.rdf
contains only those classes that have already been requested from their individual URI at least once, e.g. "Apple" is included only if someone has ever requested the following resource:
        http://www.productontology.org/id/Apple

This is necessary because there is no guaranteed way to predict which of the ca. 3.5 million Wikipedia entries make up useful and needed class definitions. We know from our research (Hepp/Siorpaes/Bachlechner, 2007) that between 8.73 % and 19.77 % of the Wikipedia entries make up for useful product classes and you can request a class definition for any Wikipedia lemma that you need to describe your objects, but such cannot be derived automatically from the Wikipedia content. Also, we do not know which classes will be needed and which others are not.

Eventually, we will add filtering techniques so that the dump will only include classes that pass a certain popularity test in RDF datasets."

Dear all:

We are happy to release http://www.productontology.org, an online-service
that provides valid OWL DL class definitions for all of the ca. 300,000 types
of products or services that are contained in the 3.5 million Wikipedia entries.

In short, www.productontology.org provides for the schema level what DBpedia
provides for the data / instance level of the Semantic Web.

A few examples:

  Laser_printer   http://www.productontology.org/id/Laser_printer
  Manure_spreader http://www.productontology.org/id/Manure_spreader
  Racing_bicycle  http://www.productontology.org/id/Racing_bicycle
  Soldering_iron  http://www.productontology.org/id/Soldering_iron
  Sweet_potato    http://www.productontology.org/id/Sweet_potato

The Product Ontology is designed to be compatible with the GoodRelations
Ontology for e-commerce, but it can be used for any other Semantic Web or
Linked Data purpose that requires class definitions for objects.

All Wikipedia translations are preserved.

Examples in RDF/XML, Turtle, and RDFa:

Any feedback is highly appreciated!

Giovanni Tummarello for very valuable feedback.

The work on The Product Types Ontology has been supported by the German Federal
Ministry of Research (BMBF) by a grant under the KMU Innovativ program as part
of the Intelligent Match project (FKZ 01IS10022B).
