In business automation
Reranking can help when the initial search returns similar but insufficiently focused passages. It cannot create a missing document or replace permission checks before a result is shown.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Business process example
A search for subscription cancellation returns several similar procedures. The ranking step prioritizes the cancellation procedure over a plan-change guide, and only the relevant passages are passed on to draft an answer.
Relevant tools
- Cohere
- The Rerank service is designed to rerank documents in relation to a query.
What to check
- Measure improvement against response time and cost. Ranking weak candidates will not fix a repository that does not contain the answer.
