Understand how FindIP's semantic patent search works under the hood.

벡터 임베딩이란?

벡터 임베딩은 텍스트를 수백 차원의 숫자 벡터로 변환하는 기술입니다. 의미가 비슷한 텍스트는 벡터 공간에서 가까운 위치에 놓이게 되어, 키워드가 다르더라도 의미 기반으로 유사한 문서를 찾을 수 있습니다.

FindIP의 임베딩 파이프라인

  1. 1. 특허 문서를 섹션별(제목, 초록, 청구항, 상세설명)로 분할
  2. 2. 각 섹션을 임베딩 모델로 벡터화하여 벡터 DB에 저장
  3. 3. 검색 쿼리도 동일 모델로 벡터화한 뒤, 가장 가까운 벡터를 검색
  4. 4. 리랭킹 모델로 최종 순위를 정밀하게 재조정

Semantic Search

Unlike traditional keyword search, FindIP uses semantic embedding to understand the meaning of your query. This means you can search using natural language descriptions, technical problems, or solution concepts — and get relevant patents even when they use different terminology.

Example

Keyword search: "lithium battery thermal" — exact match only

Semantic search: "how to prevent overheating in EV battery packs" — understands intent

Hybrid Search (2-Track)

FindIP combines two search strategies for the best results:

Track B — Hybrid

Dense vector + Sparse (BM25) search with RRF fusion. Searches at the paragraph level for precise matching.

Track C — Dense

Pure dense vector search at the document level. Fast and effective for broad topic matching.

Results from both tracks are merged using Reciprocal Rank Fusion (RRF) to produce the final ranking.
