INTRODUCTION
Ontologies. Computer-based, shared, agreed, formal
conceptualizations for – amongst others – semantic
interoperability between autonomously developed and
maintained information systems.
Multilingual Terminology Bases (MTBs) are language
resources that contain - in several languages - terms
(including variants) referring to concepts in specialized
domains. Several other types of information can be added to
MTBs in order to describe specific properties of a term, its
meaning or its use in specific communicative contexts.
Ontologies are meant for a specific purpose whereas MTBs
are more general purpose

3.
PROBLEM
Ontologies and MTBs have different purposes. How and what
are the benefits of combining these two artifacts and their
methods of construction?
At two levels
• Level of the respective artifacts
• Level of the construction methods

4.
METHOD: ONTOLOGY
ENGINEERING
Hybrid Ontology Engineering
• Method  Grounding Ontologies in Social Processes and
Natural Language (GOSPL)
• Community grounded agreements on formal and informal
concept descriptions
• Formal descriptions by means of fact-orientation
• Informal descriptions by means of an artifact called glossary

5.
METHOD: TERMINOLOGY
ENGINEERING
Multilingual Termontological Database
• MTB in which some ontological relations are made explicit
• Hierarchical relationships as well as non-hierarchical (*)
• Method  Termontography
• Explicitly distinguishes the linguistic level from the
semantic level

METHOD:
HYBRID ONTOLOGY &
MTB CO-EVOLUTION
From MTB to Hybrid Ontology
• Retrieval of generic “pre-fact types”
• Retrieval of informal descriptions
From Hybrid Ontology to MTB
• Social interactions lead the mining process
• Alignment with the hybrid ontology enables natural
language querying
• Structuring the query with NLP, generating a first structure
then annotated with the ontology

8.
TOOL
First, eating our own dog food: creation of an MTB
(termontography) ontology
Annotation of the MTB to expose data as RDF
• Creation of a SPARQL endpoint
Connection GOSPL Tool with endpoint

USE CASE
Used in the context of the cultural domain
• Retrieval of information on cultural events in Brussels
• Three languages: NL, FR, EN
• Motivation of Multilingual Termontological Databases
• Different data sources motivate the need of Ω
• Application
• Natural language querying. Query is first parsed to a
structure, and alignment with Ω facilitates the translation of
that structure into query
• Multilingual interfaces
• User comprehension of the results

11.
CONCLUSIONS
Conclusions
• Ontologies and MTBs are two different artifacts, with distinct
construction processes
• We examined how these two processes and artifacts can be
combined and presented a proposal
• Ideas were implemented in a tool, which will be part of a
greater set up
• Used the tool in the context of a project in the cultural domain.
Future work
• Implementation and integration of the natural language
query interface
• More testing and user evaluation
