In the face of the massive space resources in the Internet of things, the method of semantic classification is introduced in the construction of Spatial resource Index, which makes the traditional IR tree have the semantic feature, supports the user's semantic query to the resources, and puts forward a top-k semantic query optimization algorithm, through the use of actual data and experimental analysis The validity of the index structure and the correctness of the query result are obtained, and the performance of the algorithm is evaluated from 3 indexes, such as index construction time, query time and query accuracy rate.
