摘要： The present disclosure provides a method and an apparatus of searching information. In one example embodiment, the present techniques obtain a category click rate of a query and a category click rate of published information, calculate a similarity degree between the query and the published information based on the category click rate of the query and the category click rate of the published information, and return the published information as a successful matching result if the calculated similarity degree is higher than a first threshold. The present techniques may ensure the accuracy rate and improve the return rate to provide more return results to a user.

摘要： Sorting inquiry results includes, based on extracted inquiry results matching search conditions of a user, collecting features of the inquiry results. The collected features may be used as features of a respective inquiry result and feature fitting may be conducted based on a support vector machine (SVM) regression model to obtain a feature fitting value of the respective inquiry result. The inquiry results may be sorted based on relevancy values of the inquiry results, and, for inquiry results having a same relevancy level, the inquiry results may be sorted in a top-down manner based on feature fitting values of the inquiry results.

摘要： The present disclosure provides a search ranking method and apparatus based on a click through rate (CTR) to improve reusability and simplify a ranking process. Before a search ranking, click data of a user within a preset period of time is obtained and a respective weight of each characteristic is determined based on the click data. The search ranking may include the following operations. A query and one or more query targets matching the query are obtained. A respective characteristic of each of the query and the query targets are extracted. With respect to each query target, based on the characteristics of the query and the query targets as well as the respective weight corresponding to each characteristic, a respective CTR is obtained based on one or more models such as a regression model. The query targets are ranked based on their respective CTR and displayed to the user.
