This paper a framework and method for resolving word sense disambiguation and present the results. In this work, WordNet is used for two different purposes: one as a dictionary and the other as an ontology, containing the hierarchical structure, representing hypernym-hyponym relations. The advantage...

지식 기반 방법론은 무엇에 의존하는가? | 자율 학습은 의미 태그되어 있지 않은 말뭉치를 이용하여 학습을 하는데 이는 자료의 준비가 쉬운 반면에 정확도에 있어서 지도학습에 비해 좋은 성능을 내기가 어렵다[11][12]. 지식 기반 방법론은 사전이나 시소러스에 의존하며 말뭉치를 활용하지 않는다. 이러한 방법은 사전이라는 잘 정제된 양질의 정보를 사용한다는 장점이 있는 반면에 지도학습의 경우처럼 문맥에서 통계적인 정보를 끄집어내기는 어렵다는 단점이 있다. | |
지식 기반 방식은 어떤 유형들로 나눌 수 있는가? | 지식 기반 방식은 다시 세 가지 유형으로 나눌 수 있다. 첫째는 주해의 중첩(gloss overlap)을 이용하는 방법이고[13, 14], 둘째는 선택 제약 방식(selectional restriction), 셋째는 구조적인 방식이다. 선택 제약이란[15] 단어의 역할에 있어서 특정 단어는 특정한 대상을 취한다는 데에 착안한 방법이다. | |
워드넷은 무엇으로 구성되어 있는가? | 본 논문에서는 워드넷(WordNet)을[2] 활용하여 주어진 단어의 여러 가지 의미 중에서 가장 가능성이 높은 것을 고를 수 있는 단순한 기법을 제시한다. 워드넷은 1985년 프린스턴 대학에서 개발이 시작되었으며 15만 단어, 11만5천개의 동의어 집합(synset)과 20만여 단어-의미 쌍으로 구성되어있다. |
