이 문서에서는 Dataplex Universal Catalog 검색에서 제공하는 프로젝트 기반 시맨틱 검색 기능을 사용하는 방법을 설명합니다.
Gemini를 기반으로 하는 시맨틱 검색은 복잡한 검색 구문 없이 데이터 검색을 간소화합니다. 자연어 쿼리를 지원하므로 일상적인 언어로 리소스를 검색할 수 있습니다. 이를 통해 기술 전문성 수준이 다양한 사용자의 접근성이 향상됩니다.
키워드 검색과 마찬가지로 시맨틱 검색은 조직 내 리소스와 연결된 메타데이터를 분석하여 리소스 검색을 강조합니다.
시맨틱 검색은 데이터 검색을 위해 기술 메타데이터를 사용합니다. 관점과 같은 사용자 정의 메타데이터도 지원합니다. 시맨틱 검색은 정밀도보다 재현율을 높이는 데 중점을 둡니다.
가격 책정
Dataplex 범용 카탈로그의 시맨틱 검색은 미리보기 기간 동안 무료로 제공됩니다.
미리보기 기간 동안 dataplex-semantic-search-feedback@google.com 이메일 주소를 사용하여 Dataplex Universal Catalog팀에 의견과 제안사항을 공유해 주세요.
필요한 역할
자연어를 사용하여 Dataplex Universal Catalog에서 리소스를 검색하면 Dataplex Universal Catalog는 키워드 검색에 대한 권한과 동일한 권한을 자동으로 원활하게 적용합니다.

It supports natural language queries, so\nyou can search for resources using everyday language. This enhances\naccessibility for users with varying levels of technical expertise.\n\nSimilar to keyword search, semantic search emphasizes the discovery of resources\nby analyzing the metadata associated with the resources within an organization.\nSemantic search relies on technical metadata for data discovery. It also\nsupports user-defined metadata, such as\n[aspects](/dataplex/docs/enrich-entries-metadata#aspects). Semantic search\nfocuses on enhancing recall rather than precision.\n\nPricing\n-------\n\nSemantic search in Dataplex Universal Catalog is offered at no charge during\nPreview.\n\nDuring Preview, share your feedback and suggestions with the\nDataplex Universal Catalog team using the email address\n`dataplex-semantic-search-feedback@google.com`.\n\nRequired roles\n--------------\n\nWhen you search for resources in Dataplex Universal Catalog using natural language,\nDataplex Universal Catalog automatically and seamlessly applies the same\n[permissions you have for keyword search](/dataplex/docs/search-assets#required-roles).\n\nSearch for resources using semantic search\n------------------------------------------\n\n### Console\n\n1.

To turn on semantic search, click the **Query in natural language** toggle.\n\n3. In the search field, enter your query in natural language. The following are\n some sample queries:\n\n - `Show me the datasets that contain taxi information`\n - `Find data on vaccine distribution across different countries`\n - `Get tables with historical temperature data for major US cities`\n - `Search for hurricane tracking and storm activity datasets`\n - `US population data by state`\n4.
