Embeddings
Numerical representations of text that capture meaning, allowing AI systems to match a query to relevant content based on semantic similarity rather than exact keywords.
Embeddings are vector representations of text that encode meaning. By converting both queries and content into vectors, AI systems can measure how semantically similar they are — retrieving content that matches a question’s intent even when the wording differs.
Why it matters
Semantic matching means you no longer need exact-keyword matches to be retrieved. Content that clearly and unambiguously covers a concept can surface for many differently-phrased queries.
Implications for content
- Write clearly about a topic; don’t rely on keyword stuffing
- Cover the concept thoroughly so its meaning is unambiguous
- Disambiguate entities (who/what you are) to avoid being confused with similar ones
Connection to retrieval
Embeddings power the retrieval step in many answer engines. Clear, well-scoped content embeds closer to the queries you want to win.
