Embodiment Construction

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] The invention discloses a method and system for expressing a knowledge graph data model of spatial relations, by dividing the real geographic space into m×n uniformly distributed regular grid spaces, and mapping them to the corresponding grids in the domain knowledge graph The spatial "entities" actually establish an implicit spatial relationship ("relationships" such as clustering of administrative divisions, adjacent, non-adjacent, etc.) for the grid space "entities" arranged in matrix in the domain knowledge map, and then Establish explicit spatial relationships (subordination, inclusion, intersection, etc. "relationships") between these grid space "entities" and administrative division space "entities", provid...

Abstract

The invention discloses a spatial relationship knowledge graph data model representation method and system. The method comprises the following steps: constructing administrative division entity objects and grid space entity objects in a domain knowledge graph database; establishing subordinate and intersected relationships between entities of a grid space and an administrative division space basedon a spatial relationship analysis algorithm; carrying out geographic spatial relationship clustering analysis and spatial correlation search operation according to subordination relationships and adjacent relationships of grid space entities in a domain knowledge graph when the spatial relationship clustering analysis of massive spatio-temporal event data is carried out in order to greatly improve he real-time performance of spatial analysis operation in the field of public security business.

Description

technical field [0001] The present invention relates to the field of data search and analysis, and more specifically, to a method and system for expressing spatially related knowledge map data models. Background technique [0002] The knowledge map was originally proposed by Google as a technology to optimize search engines, and its extension has also expanded during continuous development. Taking stock of the current development of knowledge graphs, it has facilitated the application of many popular artificial intelligence scenarios, such as voice assistants, chat robots, and intelligent question-and-answer. In fact, the current artificial intelligence can be simply divided into perceptual intelligence (mainly focusing on the ability to explore pictures, videos, and voices) and cognitive intelligence (involving knowledge reasoning, causal analysis, etc.). One of the techniques. [0003] In terms of the scope of use, knowledge graphs are divided into general knowledge grap...
