Abstract
The present disclosure provides techniques to rank search results. The techniques may include acquiring a set of primitive characteristics and extracting effective characteristics from the set of primitive characteristics based on historical transaction data. The effective characteristics include characteristics that can have an influence on ranking of search results. The techniques may also include determining an initial weight of each of the effective characteristics based on the historical transaction data, and training the initial weight using the historical transaction data and a predetermined training model to obtain a final weight. Based on the final weight, the search results may be ranked. In some aspects, the techniques may also optimize the ranking to ensure the objectivity and accuracy of ranking results.
