This paper aims at developing methods of extracting figurative expressions from a domain-specific corpus and extending the multi-lingual lexical database entries for those expressions to be included. The nominal entries which can be used figuratively are selected from the annotated corpus, using the hierarchical semantic class of Sejong Electronic Dictionary. And from the raw corpus, the partially-parsed corpus are constructed automatically. To extract candidates for figurative expression, we fixed some syntactic patterns in advance, for example [NP+sbj-marker NP+obj-marker V], and extract those patterns from partially-parsed corpus. After investigating the extracted expressions and classifying them whether figurative or literal, we concluded that some nominal entries are used more figuratively in specific syntactic patterns.
