The Role of Ontologies for Mapping the Domain of Landscape Architecture
An introduction
2
The Role of Ontologies for Mapping the Domain of Landscape Architecture
Oντος = Being ; Λογια = discourse The study of categories emerged 300 A.D. in ancient Greece.

Computer Sciences have adopted a concept of applied ontologies
The Role of Ontologies for Mapping the Domain of Landscape Architecture Computer Sciences have adopted a concept of applied ontologies in the context of knowledge management. "An ontology defines a common vocabulary for researchers who need to share information in a domain. It includes machine-interpretable definitions of basic concepts in the domain and the relations among them." Noy/McGuinness, Stanford Univ. 2001
4
The Role of Ontologies for Mapping the Domain of Landscape Architecture
In the context of LE:NOTRE, ontology is not understood as philosophical discipline. It is an artefact, designed for expressing a specific domain. SHARE CONCEPTS + RELATIONS
5
The Role of Ontologies for Mapping the Domain of Landscape Architecture
Purpose of ontologies: Interpretation by machines Knowledge management Interoperability of systems Relating languages Reasoning (to some extend) Cooperation between actors Cooperation between computers
6
The Role of Ontologies for Mapping the Domain of Landscape Architecture
Ontology Development Steps ontology specification knowledge acquisition conceptualisation formalisation evaluation documentation
7
The Role of Ontologies for Mapping the Domain of Landscape Architecture
Ontologies + Learning LEARNING - Develop a body of knowledge for the considered domain in the learners mind. The skeleton of this body is a semantic network of the main domain concepts - ONTOLOGY
8
The LE:NOTRE approach so far:
The Role of Ontologies for Mapping the Domain of Landscape Architecture The LE:NOTRE approach so far: Division into subject-specific working groups (to-down) Working groups develop models of subject-specific competences (bottom-up) Next step: agree on the competence models Then: integration and implementattion of the ontology
9
The objective: A topic map of the landscape architecture domain
The Role of Ontologies for Mapping the Domain of Landscape Architecture The objective: A topic map of the landscape architecture domain Division into subject-specific working groups (to-down) Working groups develop models of subject-specific competences (bottom-up) Next step: agree on the competence models Then: integration and implementattion of the ontology
10
Potential scope of bachelor programmes within the topic map
The Role of Ontologies for Mapping the Domain of Landscape Architecture Potential scope of bachelor programmes within the topic map Division into subject-specific working groups (to-down) Working groups develop models of subject-specific competences (bottom-up) Next step: agree on the competence models Then: integration and implementattion of the ontology
11
Potential scope of master programmes within the topic map
The Role of Ontologies for Mapping the Domain of Landscape Architecture Potential scope of master programmes within the topic map Division into subject-specific working groups (to-down) Working groups develop models of subject-specific competences (bottom-up) Next step: agree on the competence models Then: integration and implementattion of the ontology
12
Request Competence Ontology
The Role of Ontologies for Mapping the Domain of Landscape Architecture Ontology potentials within LE:NOTRE: knowledge management across databases Request Competence Ontology metadata metadata metadata Course Units Projects Course Unit metadata metadata Images Excercises
13
The Role of Ontologies for Mapping the Domain of Landscape Architecture
Ontology potentials for an educational environment in and beyond LE:NOTRE Request Competence Ontology Which contents are associated with the competence? Which learning paths are proposed? Which neighbouring competences are existing? Which contents are semantically related (thematic neighborhoods)? ….across idiomatic boundaries
14
Landscape Architecture Ontology
The Role of Ontologies for Mapping the Domain of Landscape Architecture Ontology potentials beyond LE:NOTRE: Information retrieval across webites Request Landscape Architecture Ontology Semantic Web
15
The Role of Ontologies for Mapping the Domain of Landscape Architecture
Ontology potentials beyond LE:NOTRE: Interdisciplinary Communication + Stakeholder Involvement Ecology Ontology Architecture Ontology Urban Planning Ontology Landscape Architecture Ontology Public Policy Ontology Design Ontology
16
The Role of Ontologies for Mapping the Domain of Landscape Architecture
Within LE:NOTRE, learning is a core theme – Bring the network of domain concepts into peoples‘ mental networks Foundation for collaboration
17
Elements of an ontology:
hierarchy of concepts/classes (i.e.: an urban square is an instance of the concept “urban open space”) logical relations (i.e. all urban squares are urban open spaces) elements have properties (urban squares have a name, a location, a size, a designer and so on)
