Abstract

The invention discloses a method and a device for acquiring POI state information, and relates to a big data technology in the technical field of artificial intelligence. According to the specific implementation scheme, the method comprises the steps of obtaining a text containing POI information in a preset time period from the Internet; recognizing the text by using a POI state recognition model obtained by pre-training to obtain a two-tuple in the text, wherein the POI state recognition model obtains a vector representation of each first semantic unit in a text, and obtains a vector representation of each second semantic unit in the text based on semantic dependency information of the text; fusing the vector representation of each first semantic unit and the vector representation of each second semantic unit to obtain a fused vector representation of each first semantic unit; and performing label prediction on a POI name and the POI state based on the fusion vector representation of each first semantic unit. According to the technical scheme, the labor cost can be saved, and the timeliness and accuracy are improved.

Description

technical field

[0001] The present disclosure relates to the field of computer technology, and in particular to big data technology under the field of artificial intelligence technology. Background technique

[0002] POI (Point of Interest) refers to a point of interest. It is a term in geographic information systems and generally refers to all geographical objects that can be abstracted into points. A POI can be a house, a shop, a mailbox, a bus stop, A school, a hospital, etc. The main purpose of POI is to describe the location of things or events, thereby enhancing the ability to describe and query the location of things or events.

[0003] In Internet map applications, POI plays a very important role. By using POI users can easily find a place of interest and the route to that place on the map. However, due to the influence of urban planning and other factors, the information of some POIs will change over time, such as newly added POIs, relocated POIs, renamed POIs, c...
