Method and system of search result diversification

摘要

The present disclosure discloses a search method and system. A method obtains a first search result set of first search results relevant to query data submitted by a client. According to a first relevance score and a preset diversity field of each first search result in the first search result set, a second relevance score of each first search result is calculated. The preset diversity field represents an attribute category of a respective first search result. According to the first relevance score and the second relevance score, a relevance parameter score for each first search result is generated. According to a preset number of second search results and the relevance parameter score, the present number of second search results are extracted from the first search result set to display to the client. The technique achieves lower consumption of system resources, faster computation speed and more flexibility in diversification of search results.
