Information search method and apparatus, and timeliness query word recognition method and apparatus

Abstract

Embodiments of the present invention provide an information search method and apparatus, and a timeliness query word recognition method and apparatus. The information search method comprises: searching information according to a query word input by a user; determining whether the query word is a target query word, wherein the target query word is a query word with the timeliness requirement, corresponding to an information search result; and if so, raising the weight of the timeliness factor to a preset value, ranking the searched information based on the preset value and outputting the searched information, wherein the target query word has the corresponding timeliness factor which is used to calculate the score of the searched information. In the embodiments of the present invention, in the manner of determining whether the query word is the target query word, the weight of the timeliness factor is raised, and the searched information is ranked based on the preset value and then is output, so that the search requirement of the user for the timeliness information is improved.

Description

Technical field [0001] The present invention relates to the technical field of network information search, in particular to an information search method and device and a time-sensitive query word recognition method and device. Background technique [0002] With the development of the website, users can find the information they want to search by entering query words in the website. [0003] The existing information search method is: the user enters a query term, and after receiving the query term, the website finds multiple information corresponding to the query term, and calculates the score of the found information based on three dimensions, and Sort and output to the user in the order of the highest score. [0004] Among them, the three dimensions include: the relevance dimension, that is, the degree of relevance between the searched information and the query term; the quality dimension, that is the quality of the searched information, for example: the information to be searched ...

AI Technical Summary

Problems solved by technology

[0005] However, the inventor found in the process of implementing the present invention that at least the following problems exist in the prior art: since in the prior art, the scores of the found information are calculated based on the weights of the dimension factors of three dimensions, therefore, after obtaining After the score, the information displayed to the user is sorted in descending order of the score, which may be displayed in order of quality from high to low, or in order of relevance or timeliness from high to low

However, there is currently such a demand that users have timeliness requirements for the information they are looking for. For example, if the query word entered by the user is a keyword of an entertainment event that happened recently, it means that the video that the user wants to watch is relatively A new video, that is, a video whose upload time is relatively close to the current time, means that the user has a timeliness requirement for the searched video. Therefore, if the score is high at this time and the score is high, the found video will be searched according to are displayed to the user in descending order of quality, the user has no way of knowing which of the displayed videos is the newer video

[0006] Therefore, the existing information search methods cannot meet the user's search needs for time-sensitive information
