This paper gives a methodological proposal in construction of semantic network of verbs based on Domain Ontology. The existing semantic networks were not satisfactory both in quality and quantity, and mostly were limited to nouns. In this paper, we introduced the Domain Ontology in EuroWordNet database as a way of lexical semantic networks construction. First, we divided semantic relation of verbs through Domain Ontology into external relation and internal relation. The external relation means semantic relation between lexemes in different domains. The external relation was classified in terms of the relation between Top Ontology with Domain Ontology, and the relation in Domain Ontologies. We classified the internal relation into the relation between participant and event, between event and event. And event relation was divided into relations in terms of temporal order, logical causality and modality. By using the Domain Ontology and seizing the special meanings in the domain, the contents of lexical networks may be enriched. And inference of a lexeme can be made easily as finding the latent relationship between lexemes.

The purpose of this paper is to analyze the ontology of 'Mulmyeonggo' that is the thesaurus of 'the name of things', and to explain its significance in lexicography. In section 2, I roughly divided the traditional thesauruses into two types that are 'the thesauruses for a learner's dictionary' such like 'Hunmongjahoe', 'Yeokeoyuhae' etc, and 'the thesauruses for a encyclopedic dictionary' such like 'Mulmyeonggo', 'Mulbo' etc. And I suggested that the character of the thesauruses for a encyclopedic dictionary was the complex hierarchy in the classification system. In section 3, I discussed the classification system and the semantic network of 'Mulmyeonggo'. And I suggested that the classification system in 'Mulmyeonggo' was characterized by systematic features for classification. The features that used in 'Mulmyeonggo' were 'animate / inanimate', 'immovability/non stillness' and 'the primary substance- i.e. grass, wood, earth, stone, metal, water, fire' etc. In 'Mulmyeonggo' the features for classification were abstracted from the ontology that is based on the Confucian idea. But because 'Mulmyeonggo' was co mposed with the object of practical using of things, a construction of a semantic network was an important subject in 'Mulmyeonggo'. The semantic network of 'Mulmyeonggo' was characterized by the presentation of not only synonyms but also the connection between things and properties. In section 4, I discussed the significance of 'Mulmyeonggo' from viewpoint of contemporary ontology and wordnet.

This paper defines the scope of synonyms in the Korean language education. With adjectives expressing happiness and sorrow, this paper investigates the semantic and syntactic differences between vocabularies based on corpus and dictionaries. This study can be basic data for high level Korean language learners who want to distinguish the relations between synonymous relation vocabularies. This study also demonstrates that results of contrasitive analysis and error analysis can be applied to Korean language education. Rather than defining the scope and boundaries of synonyms, this study emphasizes the importance of order and instruction method for synonyms education. For this purpose, this study attempts to analyze a variety of aspects such as word frequencies and coverages.
