The invention discloses a law case digital display method and
system based on interactive query and
big data analysis, and the method comprises the steps: S1, analyzing multi-
modal data, and extracting legal entities and dominant relationships between the entities; s2, constructing a probabilistic
knowledge graph according to the legal entities and the dominant relationship; s3, analyzing the probabilistic
knowledge graph to deduce the recessive relationship of the legal entity; s4, generating an interactive
visual user interface according to the dominant relationship and the
implicit relationship; s5, taking queried and corrected data as feedback data, and continuously optimizing the multi-
modal processing model; the
system comprises a processor, a memory, a multi-
modal data receiving and analyzing module, a probability
knowledge graph construction and management module, an interpretable reasoning engine module, a
visual interaction and rendering module and a self-learning optimization module. The method has the advantages that the probabilistic knowledge graph representing information uncertainty is quantified, discovery and anti-fact deduction of the
implicit relationship are carried out, and analysis and deduction capabilities are provided for users.
