Event identification method and system based on probability soft logic PSL

The invention provides an event identification method and an event identification system based on probability soft logic PSL. The method comprises the following steps: calculating a conditional probability of at least a candidate and an event, and a candidate and a subject, an event and a subject appeared in at least a same file and/or a same sentence, and at least one of two different candidates or two different events; setting corresponding variables respectively for different conditional probabilities in a PSL model, designing a variable formula of the PSL model and iterating based on the variable formula of the PSL model, thereby maximizing the variables corresponding to the conditional probabilities of the candidates and the events, obtaining corresponding specific events of the candidates under the maximum conditions, and constructing an event identification model. The provided method can increase the accuracy in the event identification.
