Problems solved by technology

Screen out points of interest that are highly similar to existing points of interest from the information, and then determine the event corresponding to the point of interest. The accuracy of event mining is low.
Moreover, due to the need to continuously identify keywords in information information and retrieve existing points of interest, it is impossible to mine events in massive information information

Abstract

The invention discloses an event mining method and an event mining device for an interest point. The method comprises the steps that a plurality of pieces of information are acquired, the informationis screened according to a preset event verb set, and the preset event verb set comprises a plurality of event verbs. Interest point event sentences are extracted from the screened information, and interest points and events corresponding to the interest points are extracted from the interest point event sentences. Therefore, the interest points and the events corresponding to the interest pointsare captured from the information, the efficiency and accuracy of event mining are improved, and the technical problems that in the prior art, the accuracy of event mining is low, and events cannot bemined in mass information are solved.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method and device for event mining of points of interest. Background technique [0002] With the advent of the mobile Internet era, electronic maps have become one of the necessary tools for people to travel. Compared with the paper map, the provider of the electronic map can mark the relevant information of the point of interest in the electronic map, so that the user of the electronic map can understand the point of interest in more detail. For example: mark the information that a large shopping mall is temporarily closed due to interior decoration in the electronic map. Relevant information needs to be updated in time according to events related to the point of interest, so as to meet user needs. [0003] In related technologies, keywords identified from information information are used to search for existing points of interest in an electronic map. The int...
