7. The legal search system of claim 6, where: in a legal rule weight table correspondingly generated by the analysis statement, legal rules and legal regulations corresponding to other event legal rules are actively acquired by a target user except for the first event.
8. A legal searching method, characterized in that it is implemented by a legal searching system as defined in any one of claims 1-7, comprising the steps of:
step one, inputting event details in a search system by a target user;
step two, decomposing event details into a plurality of analysis sentences, then extracting event keywords in each analysis sentence, and acquiring corresponding tag sub-pools according to the event keywords;
step three, performing similar matching on the analysis sentences and the event section sentences in the corresponding acquisition label sub-pools, and acquiring event laws related to the corresponding event section sentences according to matching results;
and fourthly, carrying out weight analysis on all event laws corresponding to and extracted from each analysis statement, obtaining a law weight table according to the weight analysis result, then extracting the event laws with the highest weight value in the law weight table, and acquiring law laws and legal regulations corresponding to the event laws from a law resource pool and automatically displaying the law laws and legal regulations to a target user.
