ontologies

Baking-in bibliographic references directly into RDF / OWL ontologies

Not every part of an ontology is novel. Often enough we reuse existing works and standards to populate them. At other times the ontology implements policies and processes that are outlined in a document narrative but never before formalised into a data structure. To give credit where credit is due, and to ensure policy compliance, it can be worthwhile to integrate bibliographic citations and references directly within the ontology. Ontologies already exist to record bibliographic data.

Ontologies, what are they good for really?

Ontologies have a chequered past in the business arena, although many significant benefits have been realised over the past two decades in biological and medical research. Wrapped up in the AI hype and occasionally lumped in with knowledge management projects or taxonomy projects they are often shelved curiosities whose original purpose is lost by their champions. What is an ontology? Generally speaking, it is a set of concepts, their properties and the relationships that link the concepts together.

What is going wrong with the Semantic Web?

The US Semantic Technologies Symposium was held at Wright State University a month ago where there were great discussions with Craig Knoblock about SPARQL servers reliability1Eric Kansa about storing archeology data and Open Context, Eric Miller about the workings of the W3, mid West farmers and old bikes, Matthew Lange about tracking crops with LOD and a 'fruitful' talk with Evan Wallace about farm data storage standards. 

Thinking through these conversations, I decided to outline what I think are the troubling conclusions for our area, namely that a) Semantic Web adoption is lagging, b) we keep rehashing old problems without moving on and c) our ongoing lack of support for our own projects after which I'll suggest a few solutions.

Creating specialized ontologies using Wikipedia: The Muninn Experience.
Paper Session III, Saturday June 30, 10:30-11:30
 
Abstract:
This paper reports on the experiences of the Muninn project in creating specialized ontologies for historical governmental and military organizations using the Wikipedia data set and its linked open data companion DBpedia.  The motivation for the ontologies and the extraction methods used are explained and their performances reviewed.  Overall Wikipedia is a very accurate knowledge base from which multilingual concepts can be extracted.  The caveat is that while the information is almost always present, it is not always straightforward to retrieve because of missing structures or categorization information. Hence, an iterative methodology has been found to work best in extracting information from Wikipedia.
