Abstract

The invention discloses a mining method and device for map point of interest (POI) data. The method comprises steps of mining POI data in a POI data providing website so as to obtain a POI data set; extracting and mining geographical location data included in one or a plurality of government websites; and verifying the correctness of the POI data in the POI data set according to the geographical location data extracted and mined from one or a plurality of government websites. The mining method combines the characteristic of 'high data accuracy but high mining difficulty' of the government website with the characteristic of 'low data mining difficulty but low data accuracy' of the POI data providing website, takes the POI data mined from the POI data providing website as initial POI data, and takes the geographical location data included in the government website as standard data, thereby realizing high efficiency, high quality and high yield of the mining method for the map POI data, and solving the problem that the POI data mined from the internet includes a lot of dirty data, wrong data and invalid data.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a method and device for mining POI data of a map point of interest. Background technique [0002] POI (Point of Interest) refers to a specific geographic point that is of interest to the user or has practical uses for the user; in a geographic information system, a POI can be a house, a shop, a mailbox, a bus stop Wait. [0003] The traditional geographic information collection method requires map surveyors to use sophisticated surveying instruments to obtain the latitude and longitude of each point of interest, and then mark them down. This method is time-consuming and laborious. Since there are various POI data on the Internet, if these data can be mined from the Internet, it will greatly save manpower and time. [0004] However, POI data on the Internet is various, which is full of a lot of dirty data, invalid data and wrong data. In order to ensure the accuracy of POI ...
