Search Relevance

Human evaluators judge whether search results match users’ intended queries. They assess the accuracy, usefulness, and ranking order of results based on real user behavior patterns. This feedback trains AI algorithms to better understand context, intent, and quality, something pure automation cannot achieve on its own.

Query intent classification determines whether users want information, navigation to a specific site, or to complete a transaction. For example, “Apple stock price” is informational, “Facebook login” is navigational, and “buy iPhone 15” is transactional. Understanding intent helps search engines deliver appropriate results.

When people type something in a search box, they expect the most useful results to appear at the top. If the search shows random or confusing items, users get frustrated and may leave the website or app. A search relevance service helps fix this by checking how closely the results match what the user really wants and then improving the ranking so that the best answers come first.

We usually start with a diagnostic evaluation across a representative query set, then co‑define rubrics, sampling rules, and KPIs. After that, a steady‑state HITL program runs ongoing judgments and feeds structured feedback into your ranking, query‑understanding, and experimentation pipelines.

Annotators use rubrics that explicitly account for dominant vs. secondary intents and acceptable result mixes for each query pattern. We then tag where models over‑index on a particular interpretation, which serves as a training signal for disambiguation logic and intent‑aware ranking.

Rubrics can include policy dimensions such as harmful content, fairness, and regulatory constraints alongside pure topical relevance. This allows clients to determine when highly relevant results still need to be down‑ranked or filtered for compliance and ethical AI reasons.
