Keywords: Geospatial Information Service, Geo-collaboration Work System, Dynamic Composition, Context Relationship Abstract. For the new demand of dynamic integration of spatial data, the model and collaboration of processing functions caused by characteristics of dynamic interaction and the participants random demand for information in geo-collaboration work system, for instance, during on-line consultation meeting, the paper presented an approach considering context dynamic service composition information. Firstly, the paper introduced the dividing method of context relation in consultation from the user and GI services, interaction between services and service perspective, constructed GI service context relation, and established GI service description model considering service's context relation based on OWL-S. For the problems above, the paper proposed an approach on GI service dynamic composition based on context relationship. Then, the paper provided a framework for GI services dynamic composition, and discussed every important component of framework. Finally, an experiment about checking illegal construction on boundary was implemented to illustrate the concepts and ideas discussed in the paper.
