Knowledge graph establishment and conflict of interest identification method for case conflict of interest

By constructing a knowledge graph containing subject nodes, lawyer nodes, case nodes, and rule nodes, and combining it with a conflict of interest rule base to determine direct, indirect, and business conflicts of interest, the problem of rule and data separation in existing technologies is solved, and the comprehensiveness and reliability of case conflict of interest identification are improved.

AI Technical Summary

Technical Problem

In the judicial field, existing knowledge graph-based methods for identifying conflicts of interest in cases suffer from a separation between rules and data, making it difficult to systematically uncover multi-level potential relationships and resulting in insufficient comprehensiveness and reliability in conflict identification.

Method used

Construct a knowledge graph containing subject nodes, lawyer nodes, case nodes, and rule nodes, and establish agency relationship edges, principal relationship edges, time relationship edges, and conflict relationship edges. Combine this with the conflict of interest rule base to determine direct conflict of interest, indirect conflict of interest, and business conflict.

Benefits of technology

It improves the comprehensiveness and accuracy of conflict of interest identification in cases, and can systematically explore the potential connections between pending cases and historical cases, thereby enhancing the reliability and interpretability of conflict of interest judgments.

Abstract

This invention relates to the field of knowledge graph construction technology, specifically to a method for establishing a knowledge graph and identifying conflicts of interest in cases, comprising: S1: acquiring cases to be tried and a set of historical cases; S2: preprocessing the historical case set to obtain a case element database containing subject information, lawyer information, case information, and time information for each case; S3: constructing a knowledge graph based on the case element database and a pre-set conflict of interest rule base to obtain a case conflict of interest graph; S4: mapping the cases to be tried to the case conflict of interest graph to obtain the mapping result of the case graph; S5: judging direct conflicts of interest, indirect conflicts of interest, and business conflicts based on the mapping result of the case graph and the conflict of interest rule base to obtain the conflict of interest judgment result of the case. This invention can improve the accuracy, comprehensiveness, and reliability of case conflict of interest identification.
