The combination of grid computing and information
retrieval is the main development direction of information
retrieval in the future. This paper discusses the main
components of the grid information retrieval system, and
the key technologies are analyzed in depth, a simple and
practical model of the grid information retrieval system is
designed and implemented. The experiment shows that the
system realizes the information retrieval function based on
semantic grid which can realize the precise semantic
matching according to the specific context of the concept.
The retrieval recall factor and pertinency factor can be
improved greatly, and the search request of the users can be
satisfied.
