The present disclosure provides a semantic disambiguation method, a semantic disambiguation device, a server and a storage medium. The method includes the following. Semantic analysis is performed on a current dialog message input by a user. It is determined, based on an analysis result, whether a current service field corresponding to the current dialog message is an ambiguous field.
