First Claim
1. A method in a computer system for determining relevance of a query term to a document, the method comprising:
- identifying spans of query terms within the document;
calculating a relevance for the query term for each span that includes the query term; and
aggregating the calculated relevance for the query term for each span into the relevance of the query term to the document.

Abstract
A relevance system determines the relevance of a query term to a document based on spans within the document that contain the query term. The relevance system aggregates the relevance of the query terms into an overall relevance for the document. For each query term, the relevance system calculates a span relevance for each span that contains that query term. The relevance system then aggregates the span relevances for a query term into a query term relevance for that document. The relevance system may aggregate the query term relevances into a document relevance.
