Embodiment

[0078] 【Text sample】Typhoon is a classification of tropical cyclones north of the equator and west of the dateline in Asia Pacific countries or regions. At 20 o'clock on September 7, 2018, typhoon "Mangosteen" was formed on the Northwest Pacific Ocean; on September 15, typhoon "Mangosteen" landed from the northern part of the Philippines; The response was upgraded to level I; at 17:00 on the 16th, it landed in Haiyan Town, Taishan, Guangdong. When it landed, the maximum wind force near the center was 14, and the minimum air pressure in the center was 955 hPa. As of 17:00 on September 18, 2018, typhoon "Mangosteen" has caused nearly 3 million people in 5 provinces (regions) of Guangdong, Guangxi, Hainan, Hunan, and Guizhou to be affected, 5 people died, 1 person is missing, and 1.601 million people are in emergency Transfer and resettlement; According to the person in charge of the Emergency Management Department, the typhoon "Mangosteen" also caused more than 1,200 houses to c...

Abstract

The invention discloses a geographic knowledge acquisition method, which comprises the following steps of: 1, analyzing sources of geographic knowledge, and dividing the obtained sources of the geographic knowledge into a natural language and a graphic language; 2, carrying out feature analysis and concept modeling on the obtained geographic knowledge; 3, extracting geographic information from theobtained geographic knowledge, wherein the geographic information at least comprises identification of a geographic entity, extraction of feature information and association between the geographic entity and the feature information; and 4, generating a geographic knowledge graph. The invention aims to provide the geographic knowledge acquisition method, which can fill the blank of the existing geographic knowledge acquisition way and a method for converting the geographic knowledge acquisition way into a knowledge graph, essentially promotes the intellectualization, socialization and popularization of geographic information services, and further promotes the development of geographic information science theories and applications.

Description

technical field [0001] The invention belongs to the technical field of acquiring knowledge maps, and in particular relates to a geographical knowledge acquiring method. Background technique [0002] The Knowledge Graph is essentially a large semantic network used to describe concepts, entities and their relationships in the objective world. In 2012, Google launched a semantic search engine based on knowledge graphs, which promoted the leapfrog development of the Internet from character search to object content. After that, the knowledge graph quickly attracted widespread attention from academia and industry. At present, the knowledge map is an effective carrier for expressing information and knowledge in the computer world in a form closer to human thinking, and has become an important infrastructure for artificial intelligence applications. important application value. [0003] Geographical knowledge is the result of human cognition of the spatial distribution, evolution...
