Method for constructing ecological conservation geographic knowledge graph

Abstract

The invention relates to the field of ecological civilization, and provides a method for constructing an ecological conservation geographic knowledge graph, which comprises the following steps of: constructing an ecological conservation geographic science knowledge base by taking geographic features and an ecological civilization mode as a core, and constructing an ontology base by taking the ecological conservation geographic science knowledge base as a data basis; adopting a distributed network data acquisition technology to obtain multi-source heterogeneous network data for text space-time analysis, extracting ecological conservation geographical space-time scene events and corresponding time and position attributes, and creating an ecological conservation geographical space-time event database; and constructing an ecological conservation geographic knowledge graph according to the ecological conservation geographic ontology library and the spatio-temporal event database. By constructing and applying the ecological conservation geography knowledge graph based on the ubiquitous network, semantic association, intelligent retrieval and reasoning among different knowledge of ecological conservation geography are achieved, the capacity of a search engine is improved, and the search quality and search experience of a user are enhanced.

Description

technical field [0001] The invention relates to the technical field of ecological civilization construction, in particular to a method for constructing an ecological civilization geographic knowledge map. Background technique [0002] Knowledge graph is a branch of the field of artificial intelligence and the most important way of knowledge representation in the era of big data. In essence, it is a network knowledge base formed by entities with attributes linked by relationships, that is, a knowledge base with a directed graph structure, in which the nodes of the graph represent entities or concepts, and the edges of the graph represent the relationship between entities / concepts. various semantic relationships. At present, knowledge graph has been applied in intelligent search, in-depth question answering, social network and some vertical industries, and has become the power source supporting the development of these applications. For example, Google's Knowledge Graph has ...

Problems solved by technology

[0005] However, since the current geographical knowledge map does not cover the field of ecological civilization geography, most research focuses on specialized technologies and methods. The ecological civilization geography system is a complex giant system intersecting with multiple disciplines, covering the fields of nature, environment, humanities, society and economy. There may be a large semantic gap in the knowledge system, resulting in the lack of unified standards and norms, the lack of a unified framework based on semantics, and the existing knowledge base still relies on manual construction and maintenance, which seriously hinders the sharing and application of knowledge in the field of ecological geography
