Converting Text to Numbers

What Are Embeddings?​

Think of embeddings like converting words into coordinates on a map:

  • Similar meanings are closer together
  • Related concepts cluster nearby
  • Different ideas are far apart
  • Everything has a numerical position

Types of Embeddings​

1. Word Embeddings​

Converting single words to numbers:

  • Each word gets its own position
  • Similar words are nearby
  • Captures basic meaning
  • Handles synonyms

Example: "king" - "man" + "woman" = "queen" in the embedding space.

2. Sentence Embeddings​

Converting full sentences:

  • Captures complete thoughts
  • Maintains word relationships
  • Understands context
  • Preserves sentence meaning

3. Document Embeddings​

Converting entire documents:

  • Captures overall topics
  • Maintains document structure
  • Summarizes content
  • Enables document comparison

Example: Finding similar documents by measuring their "distance" in embedding space.

4. Cross-Lingual Embeddings​

Handling multiple languages:

  • Same meaning, different languages
  • Language-independent representation
  • Translation support
  • Cultural context

How They Work​

Creation Process​

  1. Process text input
  2. Apply embedding model
  3. Generate number sequences
  4. Store for later use

Common Uses​

  • Semantic search
  • Content recommendation
  • Document clustering
  • Similarity matching
