1. A text extraction method, performed by a server, comprising:
acquiring to-be-extracted text;
extracting a current trigger word in the to-be-extracted text using a target trigger word extraction model comprised in a target event extraction model;
generating a current query sentence according to the current trigger word; and
extracting a current event argument corresponding to the current trigger word according to the current query sentence using a target argument extraction model comprised in the target event extraction model; and
generating an event text in a structured form based on the current trigger word and the current event argument,
wherein the target trigger word extraction model and the target argument extraction model have a same model structure and parameter, and are connected in a cascading manner.
