In view of the geographic annotation evaluation problem under the network map service environment, this paper extended the content of traditional geography annotation with the unstructured text form, and defined a broad geographic annotation. Using the putting process to model the annotation behavior, first of all, need confirm the geographic annotation text classification according to the frequency class, and establish a quantitative convergence description about the spatial correlation in the putting neighborhood according to the Voronoi k order adjacency relationship, proceed to the next step, build a putting model based on the geographical annotation types and type transformation combined with the geographic annotation text and the existing geographical annotation neighborhood. Through experimental verification, in the actual case of already known two typological geographic annotation sets, putting model can effectively evaluate the newly increased geographic annotation in a reasonable way.
