Spatial knowledge service system building method based on collaborative plotting technology

Abstract

The invention discloses a global dynamic heterogeneous spatial information collaborative plotting and spatial knowledge service system. On the basis of plotting data obtained by a collaborative plotting platform, mass related heterogeneous spatial information of Africa is collected, and a plotting knowledge base is generated through data integration and knowledge reasoning; on the basis of the plotting knowledge base, a knowledge model is built by means of data mining, hot spot image-text association and the like, knowledge services with the text that 'a Chinese is attacked in Africa', and the texts of 'China-Africa international cooperation', 'Africa travel' and the like being themes are carried out, visual representation is performed on hot spot area information by means of hot spot image-text generation, network map diaries and the like, a knowledge base (stored data) is built, finally, the African spatial knowledge service system based on the collaborative plotting technology is achieved, and spatial information active services are provided for the public, the government and associated users.

Description

technical field [0001] Based on the global dynamic heterogeneous spatial information collaborative plotting and spatial knowledge service system, the present invention collects a large amount of related heterogeneous spatial information in Africa, and through data integration and knowledge reasoning, visually expresses the information of hotspot areas to realize the generation and release of hotspot images and texts. The construction of the African spatial knowledge service system belongs to the field of GIS spatial analysis application technology, and provides active spatial information services for the public, government and other relevant users. Background technique [0002] With the rapid development of information technology and Internet technology, the amount of information that people come into contact with is increasing. The information service process is actually a process of disseminating information, exchanging information, and making information more valuable. T...

Problems solved by technology

At present, domestic Internet map drawing is limited to point of interest labeling, and has a complicated review process; while foreign countries have more content collaborative drawing functions, such as Google Map Maker of Google Maps and Waze map service acquired by Google.

Unfortunately, its openness is subject to many restrictions, and users often cannot obtain sufficient freedom for drawing network maps

[0006] However, my country's spatial knowledge information is not rich enough, and the service level remains at a low level, which has begun to restrict the development of social application of spatial information, which urgently requires my country to further increase spatial knowledge mining and service levels
