Problems solved by technology

However, each data is often stored separately and defined separately, and the data cannot be linked or compatible with each other.
[0006] 2) The problem of lack of knowledge. The data in the legal industry is still dominated by unstructured text, lacking knowledge data that has a knowledge structure and can be understood by computers
[0008] 4) The construction system problem, the legal knowledge map does not have a unified and standardized construction process and system, and lacks automated auxiliary tools
[0009] Therefore, there is currently no technology that can realize the construction of legal knowledge graphs.

Abstract

The invention provides a knowledge graph construction method and system based on legal data. The method comprises a step of constructing a legal dictionary, a step of extracting a legal phrase, a stepof pre-processing a legal text, a step of initially constructing legal knowledge, a step of identifying a legal entity, a step of identifying a legal relationship and a step of constructing a legal knowledge chain. The system comprises a legal basis dictionary construction module, a legal basis knowledge base construction module, an automatic legal entity identification module, an automatic legalrelationship identification module and an automatic legal knowledge chain generation module. According to the knowledge graph construction method and system based on the legal data provided by the invention, a knowledge graph is constructed for the legal data; a knowledge graph can be constructed according to action cause data of multiple legal action causes, such as divorce dispute, contract dispute and traffic accident liability dispute of motor vehicles; and intelligent data is provided for upper applications in the legal industry.

Description

technical field [0001] The invention belongs to the technical field of data processing, and relates to a method for constructing a knowledge graph of legal data and a system capable of realizing the method. Background technique [0002] Artificial intelligence is playing an increasingly important role in our human life-they are taking over our jobs, helping us to produce more efficiently and safely, and even changing the way we live and exist. Since 2010, artificial intelligence technology has been widely used in top Internet companies such as Google, Facebook, and Baidu; in 2016, Google's strategic focus shifted from "mobile first" to "artificial intelligence first"; , artificial intelligence can double the annual economic growth rate of 12 developed economies; in the second half of 2016, the US White House Office of Science and Technology Policy issued a series of artificial intelligence strategic planning and research reports, calling on the US government to pay attention...
