Embodiment Construction

[0032] Before explaining one or more embodiments of the present disclosure in detail, it is to be understood that the embodiments are not limited to the details of construction in their particular application, as well as the steps or methods set forth in the following description or drawings.

[0033] Building a knowledge graph can organically integrate fragmented data information and upgrade it into a pollution source knowledge base with a systematic and rigorous structure. Based on this, users can query and learn knowledge concepts, and can also reason about some potential connections, thereby expanding users' knowledge and knowledge. Understanding depth.

[0034] To this end, knowledge analysis and extraction of historical statistical data of pollution sources in the Binan River Basin are used to construct, store and visualize entities and their relationships in the form of graphs, and further provide users with accurate and intelligent knowledge query services, which is hel...

Abstract

The invention discloses a knowledge graph method for identifying water environment pollution. The method comprises the following steps: determining a water environment area; collecting pollution data of the water environment area, wherein the pollution data comprises pollution source data collected from pollution source general survey and load calculation data of various pollution sources; a database suitable for expressing pollution-causing information is selected, the database is Neo4j graph data and has natural extension characteristics and an unstructured data format, and new nodes, relations or attributes can be added according to requirements; based on the pollution source data, the load calculation data of various pollution sources and the entity information of the water environment area, constructing a pollution-causing knowledge graph by using the Neo4j graph data; based on the pollution-causing knowledge graph, performing knowledge retrieval and knowledge updating to obtain pollution-causing knowledge; and according to the pollution-causing knowledge, identifying a pollution type and a pollution source of the water environment, and positioning a pollution source analysis result.

Description

technical field [0001] The invention relates to the technical field of water environment pollution control in river basins, in particular to a knowledge map method for identifying water environment pollution. The applicant's applications on the same date, titled "A Method for Estimating the Emissions of Pollutant Sources into a River" and "A Method for Accurately Identifying the Types of Pollutant Sources Entering a River at a Section Scale" are cited and incorporated herein in their entirety. Background technique [0002] There are many rivers in my country, the topography is complex, and the ecological environment is fragile. In addition, the endowment of water resources and the spatial matching of economic development in different regions are quite different. There are different levels of water environment pressure in different river basins. The causes of water pollution are complex, and water environment management faces many difficulties. . The natural attributes of the...
