Abstract

Embodiments of the present invention provide a method, an apparatus, and a computer-readable storage medium for detecting a point of interest transition event. The method for detecting interest point transition events includes: obtaining first text information from social information; filtering the first text information with trigger words to obtain second text information; and extracting interest points from the second text information Transition events; sort the interest point transition events to obtain sorting information. The embodiment of the present invention obtains the ranking information of the POI transition events, so that subsequent online operations can be processed according to the ranking information, which can ensure the online timeliness of the subsequent POI information, and can also maximize the revenue under the condition of limited resources.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method, device and computer-readable storage medium for detecting a point of interest change event. Background technique [0002] At present, the discovery of map POI (Point of Interest, point of interest) related information is reviewed by automatically discovering or manually searching articles related to POI from competing products, that is, reviewing online related events, and displaying online information to user. For example, it is found that a tourist attraction is temporarily closed from the map of a competing product. For another example, when users search for POIs, such as "xx Museum", for POIs that have been suspended or have adjusted business hours, users can be reminded in a strong style to minimize invalid trips for users. In this way, the user experience of the map can be greatly improved. At present, when building the data of POI change events, i...
