Embodiment 1

[0034] refer to figure 1 , in the present embodiment, a reasoning research system based on knowledge graph path analysis is proposed, which is used to conduct path analysis on information and establish a knowledge graph, and the reasoning research system based on knowledge graph path analysis includes:

[0035] The text information set building module is used to collect current information and construct and obtain a text information set. The text information set can contain information for building a knowledge graph, which is the information basis for building a knowledge graph. The current information acquisition channel can be bound to the information website, and the current information text can be downloaded and collected automatically. Of course, the current information can also be collected manually and a text information set can be established.

[0036] The graph type acquisition module is used to obtain the knowledge graph analysis type and path rules. It mainly incl...

Embodiment 2

[0046] The knowledge graph division module defines the weight of graph sources. Calculate the atlas block A ij The occupancy ratio of PA ij , and calculate the atlas block A ij The number of subordinate atlas blocks X, calculate the atlas block A ij-1 The number of subordinate atlas blocks x, calculate A ij-1 Occupied proportion . Thus, the map block A can be distributed ij size. The size of the graph block can now be defined for distribution, which can facilitate the viewing of the knowledge graph.

Embodiment 3

[0048] Keyword extraction module, for atlas block A ij Perform training to obtain keyword a ij , according to the keyword a ij Find a preset keyword-weight information table to obtain the weight W ij , the keyword-weight information table can be obtained according to design rules or experience, and the keyword a after training the map block ij It is a searchable part of the information table, which is easy to find, and the weight is W ij In order to obtain the influence ratio of the pattern source, the details are not repeated here.

[0049] Knowledge graph design module for , for A ij-1 Carry out area design. The proportion and weight of graph blocks can be viewed intuitively, which can facilitate knowledge graph analysis.

Abstract

The invention relates to the technical field of data mining, and discloses a reasoning research system and method for path analysis based on a knowledge graph, and the system comprises a text information set building module which is used for collecting current information and building a text information set. And the graph type acquisition module is used for acquiring a knowledge graph analysis type and a path rule. And the map source acquisition module is used for acquiring a map source. And the map block extraction module is used for training and obtaining the map block A from the text information. And the relation acquisition module is used for constructing the Aij relation of the map blocks to obtain a block relation. And the knowledge graph construction module is used for constructing a knowledge graph according to the graph blocks Aij and constructing a graph block connection relationship according to the block relationship. The knowledge graph is constructed according to the graph blocks, the relation between the graph blocks is calibrated, and the efficiency and quality of knowledge graph construction are improved.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a reasoning research system and method for path analysis based on knowledge graphs. Background technique [0002] Knowledge graph is a combination of theories and methods of applied mathematics, graphics, information visualization technology, information science and other disciplines with quantitative citation analysis, co-occurrence analysis and other methods, and uses a visual graph to visualize the core structure and development of the discipline. Modern theories of history, frontier areas, and overall knowledge structures for the purpose of multidisciplinary integration. It displays complex knowledge fields through data mining, information processing, knowledge measurement, knowledge reasoning and graph drawing, reveals the dynamic development law of knowledge fields, and provides practical and valuable references for disciplinary research. [0003] The current knowledge...
