Embodiment 1

[0085] Please refer to Figure 1-9 , figure 1 It shows a knowledge map-based supply and demand information recommendation method in the embodiment of the present invention, including the following steps:

[0086] Step 1: Obtain supply and demand information and use the method of knowledge extraction to extract entity, relationship and attribute triples from the supply and demand information, construct a supply and demand information graph according to the triples, and store the supply and demand information graph in the graph database middle;

[0087] In the embodiment of the present invention, step 1 specifically includes:

[0088] Step 1.1: Obtain user information, construct a corporate and personal graph based on the corporate entity, corporate attribute, personal entity, personal attribute, and corporate-individual relationship in user information; and construct a corporate entity graph based on corporate information; for details, see figure 2 and image 3 , showing t...

Embodiment 2

[0116] Such as Figure 10 As shown, it is another method for recommending supply and demand information based on knowledge graphs in the embodiment of the present invention, including:

[0117] Step 1: Obtain supply and demand information and use the method of knowledge extraction to extract entity, relationship and attribute triples from the supply and demand information, construct a supply and demand information graph according to the triples, and store the supply and demand information graph in the graph database middle;

[0118] Step 4: Recommend supply information that matches the demand information or demand information that the demand party may need for the demand side according to the supply and demand information graph; and / or

[0119] According to the supply and demand information graph, the demand information matching the supply information is recommended to the supplier.

[0120] Such as Figure 11 As shown, in the embodiment of the present invention, the recomm...

Embodiment 3

[0142] An embodiment of the present invention also provides a supply and demand information recommendation system based on a knowledge graph, the terminal device includes: a memory, a processor, and a computer program stored in the memory and operable on the processor, the processing When the computer executes the computer program, the above-mentioned method is realized.

[0143] It should be understood that in the embodiment of the present application, the processor may be a central processing unit, and the processor may also be other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC ), off-the-shelf programmable gate array (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. Wherein, the general-purpose processor may be a microprocessor or the processor ...

Abstract

The invention relates to the technical field of supply and demand information recommendation, and discloses a supply and demand information recommendation method and system based on a knowledge graph,and the method comprises the steps: obtaining supply and demand information, extracting entities, relationships and attribute triples from the supply and demand information through a knowledge extraction method, constructing the supply and demand information graph according to the triples, and storing the supply and demand information graph in a graph database; receiving demand information or supply information input by a user, calling the graph database, and searching the supply information matched with the demand information or the demand information matched with the supply information in the supply and demand information graph; and generating a corresponding recommendation list according to the supply information or demand information obtained by matching, and returning the recommendation list to the user. Accurate supply and demand information is provided for supply and demand parties based on the knowledge graph, and the retrieval speed and precision are improved; meanwhile, related supply and demand information is intelligently recommended to supply and demand parties based on historical data in the knowledge graph.

Description

technical field [0001] The invention belongs to the technical field of supply and demand information recommendation, and in particular relates to a supply and demand information recommendation method and system based on knowledge graphs. Background technique [0002] In the information age, the network is an inseparable tool for people's life and work. In the network, people can share information and obtain information. Information sharing and interconnection make people's life and work more convenient. For example, enterprises obtain information through the Internet and choose cost-effective suppliers; enterprises can also promote their products or services through the Internet to obtain benefits. At this time, a professional information service platform that provides supply and demand information for both parties came into being. [0003] The existing supply-demand information docking platform is more inclined to the form of a comprehensive information service platform. U...
