METHOD AND APPARATUS FOR GENERATING A SUGGESTION LIST

摘要

Embodiments of the present invention provide a method and apparatus for generating a suggestion list. The method includes merging a current set of multiple query candidates (QCs) with two or more historical sets of multiple QCs to obtain two or more corresponding modified sets and merging the two or more modified sets. The current set of multiple QCs is extracted from multiple digital documents (DDs) belonging to a first time period. Each of two or more historical sets of multiple QCs are extracted from multiple DDs corresponding to at least two time periods. Each of the two or more time periods begin prior to the first time period. Each of the two or more time periods is greater that the first time period. Each of the two or more time periods differ in duration and recency.
