Abstract

The invention provides a keyword recommendation method and device, and aims to solve the problems of inaccuracy in recommendation results, limitation on recommended information coverage and incapability of meeting the demands of a user. The method comprises the following steps: receiving inquiry information, and partitioning the inquiry information into at least one inquiry keyword; looking up history search items including the inquiry keyword to serve as matching history search items, and acquiring history search items which are correlated with the matching history search items to serve as correlated history search items, wherein both the matching history search items and the correlated history search items include at least one keyword; selecting keywords of which the relevance with the inquiry keyword satisfies a preset relevance condition from the matching history search items and the correlated history search items to serve as recommended keywords; and displaying the recommended keywords and selection controls corresponding to each recommended keyword. The recommended information coverage is large; the accuracy of the recommendation results can be increased; and various demands of the user can be met.
