Method for creating knowledge base engine on basis of sudden event emergency management and method for inquiring knowledge base engine

The invention relates to the technical field of comprehensive emergency management for cities, in particular to a method for creating a knowledge base engine on the basis of sudden event emergency management and a method for inquiring the knowledge base engine. The method for creating the knowledge base engine is characterized in that when a knowledge base is created, relevant data are extracted from unstructured text information, useless data are filtered out, and the structure of the unstructured text information is modified, so that the uniformity of the data is guaranteed; extracted contextual contents of the information are subjected to structured analysis, and features of the contextual contents are extracted and stored in a feature library to be used as characteristic words and expressions of knowledge; and after being subjected to automatic segmentation, the extracted information is classified according to information classification standards, and a correlation between the knowledge and the classified information is created. The method for inquiring the knowledge base mainly includes steps of semantic comprehension, comprehension of the knowledge and retrieval of the knowledge. The method for creating the knowledge base engine and the method for inquiring the same have the advantages that shortcomings of an existing knowledge base in the aspects of classification storage, precision inquiry and the like are effectively overcome, and the methods can be applied to creating and inquiring the knowledge base engine for sudden event emergency management.
