авторStatistical Semantic Search provides deep insight into unstructured documents stored in SQL Server databases by extracting and indexing statistically relevant key phrases. Then it uses these key phrases to identify and index documents that are similar or related.

What can you do with Semantic Search?
Semantic search builds upon the existing full-text search feature in SQL Server, but enables new scenarios that extend beyond keyword searches. While full-text search lets you query the words in a document, semantic search lets you query the meaning of the document. Solutions that are now possible include automatic tag extraction, related content discovery, and hierarchical navigation across similar content. For example, you can query the index of key phrases to build the taxonomy for an organization, or for a corpus of documents. Or, you can query the document similarity index to identify resumes that match a job description.
