Operation and maintenance knowledge base updating method, system and device based on operation and maintenance events and medium

The invention discloses an operation and maintenance knowledge base updating method, system and device based on an operation and maintenance event, and a storage medium. The method comprises the following steps: obtaining operation and maintenance event data; performing correlation screening on the operation and maintenance event data to obtain a word vector training set; according to the word vector training set, updating a historical operation and maintenance knowledge base model to obtain a first operation and maintenance knowledge base model; inputting a received new operation and maintenance event into the first operation and maintenance knowledge base model to obtain a first knowledge base entry, and inputting the new operation and maintenance event into a preset operation and maintenance knowledge base to obtain a second knowledge base entry; and updating the preset operation and maintenance knowledge base according to the first knowledge base entry and the second knowledge base entry. According to the
