〔Problem 1〕:SYNONYMSYNONYM (Multiple Terms to One Concept)・example: column = pillar・difficulty: easier to cope with・definition: not necessary・solution: thesaurus
or standardized terminology list
Problems against Standardization of Terminology
〔Problem 2〕:HOMONYM (One Term to Multiple Concept)・example: column (designed) = column (structural)・difficulty: more difficult to cope with・definition: indispensable・solution: library/dictionary with usage &
definition
COLLECTION OF TERMS is only a starter of JCCS development,
IDENTIFICATION OF CONCEPT is a key task to JCCS implementation.

Problems to be solved / Issues to be challenged
Development of standardized classification system based on object-oriented framework to be used as intermediate translation/mapping system to stay existing systems in practice
Each domain member/system is liable to regard their domain tobe the whole world, and doesn’t like to change the way how touse their own terminology and concept definition.Existing systems are mostly developed with self-contentedcore technologies like coding and/or classification systems tobe difficult or impractical to be changed afterwards . Many Japanese people are not accustomed to strict semantic consideration.
