적절히 번역할 말이 떠오르지 않아 Ranking/Clustering이라고 두었습니다만, 구글에서 저번 주 "Ranking and Clustering of Geo-Located Objects"라는 내용으로 특허를 신청하였다고 합니다.
한마디로 요약하자면, 구글어스나 구글맵에 나타나는 지리적 객체를 데이터베이스에서 보다 효율적으로 분류하는 방법에 관한 특허입니다. 위의 링크를 따라 들어가면, 지구모델에 3차원 콘텐트 등의 지리 콘텐트를 저장하고 접근하는 시스템 혹은 방법론으로, 콘텐트를 다수준 계층 인덱스(multi-level hierarchical index)로 저장하고, 그 인덱스 내에 하위 레벨의 콘텐츠 정보를 저장한다고 말하고 있습니다.
나중에 생각나면 한번 자세히 읽어볼까... 하는데, 문서중에 quardtree란 단어를 보니 기존 방법론과 그다지 다르지 않을 것 같다는 생각도 들고요, 그런데.... 원래 글을 보다가 아래 댓글을 보니 이 특허가 Silly Patents라고 하는 분이 계시네요~~
