[AISWorld] New Issue Applied Ontology published

[Isabella Distinto]

NEW ISSUE APPLIED ONTOLOGY PUBLISHED 

We are happy to announce the
publication of Volume 9, Issue 1 (2014) of Applied Ontology [1]. 

The
issue [2] contains the following papers: 

Engineering ontologies for
question answering [3] 

Marten Teitsma, Jacobijn Sandberg, Guus
Schreiber, Bob Wielinga and Willem Robert van Hage 

DOI
10.3233/AO-140130

_Abstract:_ 

Using an ontology to automatically
generate questions for ordinary people requires a structure and concepts
compliant with human thought. Here we present methods to develop a
pragmatic, expert-based and a basic-level ontology and a framework to
evaluate these ontologies. Comparing these ontologies shows that
expert-based ontologies are most easy to construct, but lack required
cognitive semantic characteristics. Basic-level ontologies have
structure and concepts which are better in terms of cognitive semantics
but are most expensive to construct. 

An ontology co-design method for
the co-creation of a continuous care ontology [4]

DOI 10.3233/AO-140131

_Abstract:_ 

Ontology engineering
methodologies tend to emphasize the role of the knowledge engineer or
require a very active role of domain experts. In this paper, a
participatory ontology engineering method is described that holds the
middle ground between these two 'extremes'. After thorough ethnographic
research, an interdisciplinary group of domain experts closely
interacted with ontology engineers and social scientists in a series of
workshops. Once a preliminary ontology was developed, a dynamic care
request system was built using the ontology. Additional workshops were
organized involving a broader group of domain experts to ensure the
applicability of the ontology across continuous care settings. The
proposed method successfully actively engaged domain experts in
constructing the ontology, without overburdening them. Its applicability
is illustrated by presenting the co-created continuous care ontology.
The lessons learned during the design and execution of the approach are
also presented. 

Measuring concept similarity in ontologies using
weighted concept paths [5] 

_Delia Rusu, Blaž Fortuna and Dunja
Mladenić_ 

DOI 10.3233/AO-140132

_Abstract:_ 

Semantic similarity and
relatedness between concepts have been extensively studied in different
areas ranging from psychology to computational linguistics. In this
paper we address the problem of determining the similarity between
concepts defined in a knowledge source such as an ontology. The focus is
measuring similarity between concepts from the same ontology. We propose
a concept similarity algorithm based on geometric models for
representing concepts and relationships, which can be applied to
different types of ontologies. The key idea is the concept weighting
scheme which allows for quantifying the degree of abstractness of
concepts. The evaluation settings involving two ontologies validate and
highlight the advantages and disadvantages of the proposed approach.
Using the proposed measure, which closely resembles the human judgment
of similarity, we can reliably recreate predefined concept clusters, and
generate more informative concept paths.
