    摘要： A method and system for determining relevance of a document to a query based on identifier match distance is provided. The relevance system analyzes a training set of queries and documents to determine the relationship between identifier match distance and relevance of a document to a query. The identifier match distance indicates the distance from the end of an identifier of a document to an identifier term that matches a query term. The relevance system generates a prior relevance probability that a document with a certain identifier match distance is relevant to a query. The relevance system uses the prior relevance probabilities to determine relevance of documents to queries based on identifier match distance.

    摘要： 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.

    摘要： A method and system for identifying the importance of information areas of a display page. An importance system identifies information areas or blocks of a web page. A block of a web page represents an area of the web page that appears to relate to a similar topic. The importance system provides the characteristics or features of a block to an importance function that generates an indication of the importance of that block to its web page. The importance system “learns” the importance function by generating a model based on the features of blocks and the user-specified importance of those blocks. To learn the importance function, the importance system asks users to provide an indication of the importance of blocks of web pages in a collection of web pages.
