ABSTRACT
A concept has its own position within the concept system. When we construct a thesaurus, therefore, it is necessary to analyze the concepts and generalize their characteristics so that each concept can find its own position within the concept system. However, the concept has multiple characteristics and the concept system also varies according to the characteristics that determine the concepts. For this reason, if we base the concept system on only one of the characteristics, the concept relations within the thesaurus can be biased toward a certain view and the interoperability of the thesaurus also becomes weak.

To solve this problem, this thesis attempts to construct a thesaurus that enables the multi-dimensionality of the concept and various concept systems efficiently. The subject field of this thesaurus is zymurgy, specifically beer brewage, since brewing words are so concrete that they can be analyzed more precisely within their characteristics. The construction methods are as follows:

First, beer terminology was collected from beer dictionaries and beer style
guides and normalized into a controlled vocabulary. The definitions in the
information resources provided the characteristics of the beer terminology.

Second, the concept was analyzed for conceptual modeling, according to the
international standard(ISO 704: 2000(E)).

Third, analyzed characteristics were categorized into the basic categories,
facets, and isolated by colon classification.

Fourth, a terminological database was constructed using SQL Server 2000
and characteristics were manipulated in order to sort and represent the
conceptual relationships.

The characteristics of this thesaurus are as follows:
First, we can verify the relationships of the terms based on essential and
delimiting characteristics by clarifying the term-concept multiple relationships
and controlling the forms of the terms and characteristics.

Second, we can assign the concepts to various categories according to their
characteristics. This enables us to construct a multidimensional concept system
and reduce the confusion within the complex conceptual relationships.

Third, we can identify the inherited characteristics of the concept with a
range of terms, from broad to narrow. Therefore, it is possible to extract the
proper broad and narrow terms among many related terms according to the
perspective of the thesaurus user.

Lastly, we can transform the representation of the concept system
according to the purposes or needs of the thesaurus user. By sorting or
categorizing the characteristics in the terminology database with various
criteria, we can dynamically show the hierarchical structures and conceptual
relationships.

As seen in the above results, this study suggests that it is possible to
enhance the interoperability and usability of the thesaurus by changing the
facet citation order and showing multidimensional conceptual relationships. To
use this thesaurus practically, we should identify the essential characteristics of
the concept with more clarity. Moreover, it is necessary to precisely deal with
the phase relationships as well as facet relationships.
