Method and system for constructing knowledge graph based on legal data

Abstract

The present invention provides a method and system for constructing a knowledge map based on legal data. The method includes: a step of constructing a legal dictionary, a step of extracting legal phrases, a step of preprocessing legal texts, a step of initially constructing legal knowledge, a step of identifying legal entities, and a step of identifying legal relationships, The step of constructing a legal knowledge chain; the system includes a legal basic dictionary building module, a legal basic knowledge base building module, a legal entity automatic identification module, a legal relationship automatic identification module, and a legal knowledge chain automatic generation module. The invention realizes the construction of a knowledge map for legal data, and can build a knowledge map for multiple legal cases, such as divorce disputes, contract disputes, and motor vehicle traffic accident liability disputes, and provides an intelligent solution for upper-level applications in the legal industry. data.

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...

AI Technical Summary

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.
