A semantic geospatial service matching algorithm

The service matching algorithm is key to service discovery. In this paper, according to the four-level matching algorithm, the geospatial services discovery algorithm is also designed, which uses hierarchy matching, and uses ontology classification tree in I/O matching to converse the ontology similarities into the distance between nodes. It is proved that the new algorithm not only differentiates the geospatial services matching level, but also differentiates the similarities between the identical matching level, and can meet the geospatial services discovery well.
