Abstract

The invention discloses a method and a device for extracting POI (Point of Interest) data from webpages, and relates to the technical field of information point extraction. The method comprises the following steps: acquiring a plurality of webpages comprising POI data; performing address mode clustering on the webpages according to the URL (Uniform Resource Locator) address of each webpage; sequencing a plurality of address modes based on the quantity of webpages corresponding to each address mode to obtain the sequencing result of each address mode; selecting N address modes with largest webpage quantities; extracting POI data comprised in the webpages corresponding to the N address modes respectively. Through the method and the device, mass webpages of POI data can be determined from hundred-billion-scale webpages more rapidly, and the POI data are extracted from the webpages more accurately.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for extracting POI data in a webpage. Background technique [0002] POI: The abbreviation of "Point of Interest". The data in each POI generally includes information such as name, category, longitude, latitude, nearby hotels, restaurants and shops, and can be used as a location identifier in an electronic map. Map search requires a large amount of POI data as a search source, and POI data is mainly constructed through purchase, cooperation or self-construction. [0003] The Internet contains a lot of geographic location information that can be used as POI data. For example, a company will give its address and contact information on its homepage, and a gourmet website will give the specific location of the store and order phone information, etc. These contain POI data. The web page provides a rich source of data for map searches. [0004] However, these ...
