In terminological concept modelling only relevant subconcepts are registered. This means that not all possible ‘combinations’ of concepts from two or more groups (dimensions) will be registered, e.g. a concept universal secondary prevention is not relevant.

CAOS implements more restrictive terminological principles than i-Model.
CAOS helps the user in setting up consistent ontologies adhering to the terminological principles.
CAOS is based on the UML notation, but extensions are needed.
![Page 15: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/15.jpg)
The backbone of this concept modelling is constituted by characteristics modelled by formal feature specifications, i.e. attribute-value pairs.
![Page 16: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/16.jpg)

Attempt at creating an illegal polyhierarchy: a concept universal selective prevention with two superordinate concepts within the same group (dimension TARGET GROUP).
![Page 19: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/19.jpg)
The CAOS prototype is based on UML notation, but extensions are needed for terminological concept modelling
UML class diagrams:
• not possible to represent several dimensions, from which one may be chosen as the subdividing dimension
• no notation for the specification of dimension values, at least not in the way it is done in CAOS
• no notation for feature specifications (it is possible to use a facility of UML which comes close to feature specifications as used in CAOS: in specializations it is possible to introduce attributes with initial values).

ontology
NOTE: An ontology may comprise all kinds of relations between concepts, e.g. generic, partitive and temporal relations.
Synonyms: concept model, concept system
A data model should always be based on an ontology, but sometimes a data model, represented by means of an ER or a UML diagram, is referred to as an ‘ontology‘. Our recommendation is to use the term ‘ontology‘ only as defined here. Please observe that the term ‘conceptual model‘ is referring to a kind of data model.An ontology may typically be used for the precise description of concepts.

taxonomy
NOTE: A taxonomy is a kind of classification system, that comprises exclusively generic relations between the categories, in contrast to an ontology, which is a kind of model that may comprise all kinds of relations between concepts.
A taxonomy may typically be used for defining the types of data categories used within a specific field, eg. within the field of product description.

Principles for building taxonomies for metadata
Examples: • A taxonomy for lexical and terminological data.• A taxonomy for any other kind of data collection.
TC 37 should be a pioneer within this field!Such taxonomies, which describe the contents of data
collections, also comprise systematic definitions and examples which will make it easier to classify data elements.
Motivation: It is extremely important to be able to describe elements of
data collections systematically in order to build databases / IT systems for storage, management and exchange of data. Many metadata vocabularies are not built on the basis of the principles of taxonomies, which means that they may be incomplete, inconsistent and difficult to use.
![Page 46: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/46.jpg)
Principles for the use of concept models (ontologies) in developing data models
Examples: • Concept model for central concepts that form the basis of the
development of a data model for a terminology database.• Concept model for any other kind of database / IT system
(e.g. Electronic Health Care Systems) and the corresponding data model.
This project is not the same as the NWI in TC 37 SC 1 on Guidelines for applying concept modelling in terminology work (N 273).
Motivation: Many data models are still developed without being based on a
concept model. The two concepts ‘concept model’ (ontology) and ‘conceptual data model’ are very often mixed up. Ontology is often used for conceptual data model.

Principles for the development and use of meta models
This project should comprise guidelines based on the experience gained from the development of the meta model in ISO 16642.
It is related to the previous proposal.
Motivation: It is a non-trivial job to develop a meta model: How detailed should / could a meta model be? How to build specific data models on the basis of a meta
model?

Proposal for a Taxonomy of Lexical Metadata Categories
for ISO TC 37
Terminology and Other Language Applications
![Page 50: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/50.jpg)
ISO TC 37 published a standard in 1999 specifying data categories used in terminological resources, ISO 12620:1999, Computer assisted terminology management ― Data Categories.
In 2003, TC 37/SC 3 initiated a revision of the existing document with the intention of creating a family of data category standards designed to meet the needs of terminologists and other language experts developing a variety of electronic linguistic resources.
The intention was to include data categories for a variety of applications, including for example terminological and lexicographical data collections as well as machine translation lexica, cf.: SC 3 Systems to manage terminology, knowledge and content SC 2 Terminographical and lexicographical working methods SC 4 Language resource management.
![Page 51: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/51.jpg)
At the same time it was suggested to set up a Data Category Registry (DCR) for all the above mentioned kinds of lexical data, cf. also Ide & Romary (2004). The DCR is intended to be compliant with ISO 11179-3, Information technology — Metadata registries (MDR) — Part 3: Registry metamodel and basic attributes.
![Page 52: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/52.jpg)
The data categories of ISO 12620:1999 were classified in three major groups, and the groups were further subdivided into ten sub-groups:
A.1 term
A.2 term-related information
A.3 equivalence
A.4 subject field
A.5 concept-related description
A.6 concept relation
A.7 conceptual structures
A.8 note
A.9 documentary language
A.10 administrative information
Term and term-related data categories:
Descriptive data categories:
Administrative data categories:
![Page 53: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/53.jpg)
This structure is not homogenous, i.e. it reflects various subdividing criteria (dimensions), and it does not give a very clear overview of the data categories. One dimension is for example term-related information vs. concept-related description. Here it is not clear why e.g. subject field and concept relation do not fall within the group: concept-related description.
An example of term-related information is A.2.1.18.1 collocation, while an example of concept-related information is A.5.3 context (a text or part of a text in which a term occurs). Types of contexts can, among others, include: defining context (a context that contains substantial information about a concept, but that does not possess the formal rigor of a definition) and linguistic context (context that illustrates the function of a term in discourse, but that provides no conceptual information).
![Page 54: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/54.jpg)
It seems as if the structure of ISO 12620:1999 is to some extent based on the structure typically found in a terminological entry. Since the above mentioned DCR of TC 37 will also include data categories of dictionaries, this structure is not very appropriate.
Consequently it was decided to give up a classification of the categories.
It is however difficult to ensure completeness, consistency, user-friendliness and extensibility of the above mentioned DCR, if there is no structure of the data categories.
![Page 55: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/55.jpg)
The structure of the DCRAs already mentioned the DCR will contain data categories that are relevant in various areas, such as terminology, lexicography and machine translation. These areas are referred to as thematic domains.
In August 2007 there was an introductory meeting for the TC 37 Data Category Registry, in which all Sub-Committees and Working Groups that have any activities involving data categories were requested to nominate experts to serve on the Thematic Domain Group (TDG).
The idea was, that each TDG should be charged with the specification of domain-specific data categories for a specific data processing environment within TC 37.
![Page 56: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/56.jpg)
Figure 1 (from Wright 2004) illustrates clearly that the various subsets of the DCR, i.e. the thematic domains, will overlap. For example, the data categories part of speech and grammatical gender will be relevant in all three different thematic domains.
![Page 57: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/57.jpg)

Part 1: Taxonomy for the classification of information types
’STANLEX’
Danish Standard: DS 2394-1 (1998)
![Page 58: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/58.jpg)
STANLEX taxonomy
Main categories based on linguistic disciplines
etymological information grammatical information graphical information phonetic information semantic information usage
In addition to these categories there are some categories for administrative information and structural information.
This taxonomy was developed by a group of terminologists, lexicographers and people working with machine translation and other kinds of natural language processing.
![Page 59: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/59.jpg)
Grammatical information
• Part of speech• Gender
• Information on inflection • Stem• Paradigm information• Inflected form
• Word formation
• Syntax • Syntactic frame (valency)• Specification of syntactic frame• Specification of auxiliary verb• Syntactic function

Main group Category Subcategory
Usage • Examples of usage • Citation• Collocation

![Page 61: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/61.jpg)
All main groups, categories and subcategories are defined and exemplified. The structure of this taxonomy gives a much clearer overview of the data categories than the original structure of ISO 12620:1999, and it is clearly better than a plain alphabetical list.
The use of a taxonomy makes it much easier to check whether the DCR of ISO TC 37 comprises all relevant data categories within a certain group. In the case of proposals for new data categories it is also much easier to check whether the category is already in the DCR, maybe under another category name.
![Page 62: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/62.jpg)
Proposal for a taxonomy for lexical metadata categories
On the background of the above mentioned advantages of using a taxonomy for the classification of metadata categories it is suggested that the principles of the taxonomy of DS 2394-1:1998 are used for the structuring data categories in the DCR for lexical data in ISO TC 37.
There will no doubt be a need for more categories and subcategories than those found in DS 2394-1:1998, but it will be easy to fit new categories into the structure, as long as they are mutually independent.
There may also be a need for adjustments of the structure, since there do exist different ways of classifying lexical data.
![Page 63: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/63.jpg)
However, DS 2394-1:1998 is a good starting point, and using the principles of this taxonomy will ensure
completeness
consistency
user-friendliness
extensibility

Overview
![Page 65: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/65.jpg)
Ontologies (concept models) and conceptual data models have different aims:
• ontologies aim at concept clarification and mutual understanding of concepts and consistent use of terms
• conceptual data models aim at specifying the information types of an IT system and their mutual relationships
In order to produce a well-functioning database it is necessary to know the concept model for the domain underlying the database structure, i.e. you have to be familiar with the central concepts of the domain in which the database is going to function.
![Page 66: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/66.jpg)
Ontologies (concept models)
conceptual data models
information about concepts in the form of feature specifications and concept relations (information about meaning)
information about the classes in the form of attributes and associations between the classes
NB! The attributes of the data model give no information about the meaning of the classes, but only a specification of what kind of information will be given about the entities represented by the classes in question.
![Page 67: ISO TC37/SC4 N433 Busan 2007 ONTOLOGIES & TAXONOMIES Bodil Nistrup Madsen Department of International Language Studies and Knowledge Technology](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649f585503460f94c7db3b/html5/thumbnails/67.jpg)
• ontologies and data models do have something in common
but• there is no one-to-one correspondence between an
ontology and the data model of the database:
• There is no one-to-one mapping between concepts
and characteristics in the ontology and classes and attributes in the data model.
• Some concepts correspond to attributes or values
in the data model - some concepts may not correspond to classes, attributes or values.

A concept system for concepts may comprise concepts such as superordinate concept and subordinate concept (both subordinate concepts to concept).
These concepts are not found in the data model.

Conceptual data model
There are no corresponding classes: superordinate and subordinate concepts in the conceptual data model; rather, they will be represented by means of the attributes C-ID1 and C-ID2 on the class concSystRel, and the corresponding table concSystRel relates two concepts to each other together with a specification of which relation type (attribute R-ID) holds between them.

In multilingual terminology work concept systems will be established for all languages in a project.
In some cases one concept in one language may be partially equivalent to several concepts in one or several other languages. This also means that the concept systems of the individual languages differ.
Therefore it should be possible in a terminology database to establish an equivalence relationship between one concept in one language and two or three concepts in another language.

• Domain specific ontologies should be based on the principles of terminological ontologies.
• Concept clarification is needed wrt. ontology, taxonomy, data model etc.
• An ontology of ontologies would help in this concept clarification
• A taxonomy for lexical data for TC 37 will ensure completeness, consistency, user-friendliness and extensibility
• Terminological ontologies and conceptual data models differ
• Introducing multilingualism in ontologies requires modelling of partiel equivalence between concepts
