1. Research Project Title
“Expanding Database of Semantic Relations"
2. Objective and Necessities of Research Project
• In order to grasp Korean lexical semantic information
multidimensionaly and systematically, it is necessary to
construct Korean dictionary based on lexical semantic
system.
• Expanding database of the Korean dictionary including other
various semantic relations(original word, abbreviation, similar
meaning word, honorific word, humble word, and reference
word).
3. Content and Scope
• Expanding lexical semantic relation database (polysemy level
30,000 nouns and 2,000 predicates)
- Selecting words in basic words among 50,000 words for
Open multilingual dictionary, that are not included in the
database.
- Extracting the additional semantic words that have
relations with original word, abbreviation, similar meaning
word, honorific word, humble word, and reference word.
- Adding the main title words with which subtitle
predicates are related.
- Including high frequent everyday words.
- Selecting high frequent words from Sejong corpus that
were not included in database.
• Construction of semantic relations in polysemy level
- Construction of semantic relations(hypernym, hyponym,
synonym, and antonym) for additional nouns.
• Construction of subcategorization of expanded predicates.
- vii -
- Modification of subcategories of predicates and
subcategorization (including exclusive relation) for the
additional predicates.
- Semantic clustering in polysemy level for all selected
predicates.
• POS and polysemy tagging for definition and examples of the
additional words.
• Verification and modification the semantic relation in
database.
- Verifying the noun semantic relation(hypernym, hyponym).
- Excluding nouns which cannot be combined with predicate
in subcategorization.
• Modification of tools for tagging definition/example and
subcategorization.
• Modification of WEB browser which can display the excluded
nouns in subcategorization.
4. Applications and Expectation
• Construction of Open WEB dictionary to present Korean
lexical semantic information multidimensionaly and
systematically.
• Vitalization of industry of Korean information using the
systematic Korean lexical semantic database.
