[0003] At present, the identification of timeliness search strings is realized based on the timeliness probability table. The timeliness probability table is based on the timeliness type summed up based on the search words that meet the new requirements and the search words based on the release time statistics of the clicked pages in the search log. However, since the timeliness probability table does not use the prior knowledge of the current hot news, it will lead to delayed recognition and some unrecognizable problems. In addition, the timeliness probability table will also be due to inaccurate data in the search log. Imperfect, resulting in errors in the recognition results

The invention provides a search string processing method and device, a computer readable medium and electronic equipment, and relates to the field of information search. The method comprises the stepsof obtaining a hot event set, and preprocessing each hot event in the hot event set to obtain event features corresponding to each hot event; constructing a first graph structure according to the hotspot event and the distance between the hotspot events, and classifying nodes in the first graph structure according to a greedy algorithm to obtain an event cluster containing a target event; constructing a second graph structure according to the segmented words of the hot events in the event cluster, and obtaining event cluster features based on the second graph structure; and identifying the timeliness of the search string based on the event features and the event cluster features. According to the invention, the event cluster and event cluster feature mining efficiency can be improved, andthe timeliness recognition efficiency and accuracy of the search string can be improved.
Description
technical field [0001] The present disclosure relates to the technical field of information search, and in particular, relates to a search string processing method, a search string processing device, a computer-readable medium, and electronic equipment. Background technique [0002] With the rapid development of the information age, the amount of information has increased significantly. In order to improve the efficiency of information acquisition, users can enter search terms in various websites to obtain corresponding resources. For example, one or more search terms can be entered in news websites to obtain corresponding resources news content. Users are usually more interested in recent popular events and popular people. When obtaining relevant information about this event and this person, they also hope that the obtained information is up-to-date, and have certain requirements for timeliness. [0003] At present, the identification of timeliness search strings is realiz...
