Based on the configuration and application demands of relay protection and fault information system,this paper expatiates on the communication protocol and information semantic needed in the system.

Markov chain model based on ontology semantic measurement is used to identify which active session a request should belong to.

The features of ontologies in the semantic web are explored and the method of actualizing the mapping among ontologies by means of semantic measurement techniques is advanced,thus the problem of determining the similarity between two ontologies is solved fairly well.

By means of semantic measurement, the plan can fulfil the query map under different settings, and thus the problem of queryi.

We analyze the spatio-temporal characteristics of GIS, introduce the cellular automata, propose a formal definition of spatio-temporal ontology and a method based on spatio-temporal semantic granularity, and discuss an integrated GIS architecture based on ontology and semantics.
