The invention discloses an answering information acquisition method and device. The method comprises the following steps that: according to target asking information obtained by a client side, determining a target keyword corresponding to the target asking information; according to the target keyword, determining a target information category to which the target asking information belongs in a plurality of information categories; and obtaining target answering information corresponding to the target asking information from a target information group in multiple information groups, wherein thetarget information group comprises multiple pairs answering information and asking information which have a corresponding relationship, and the answering information contained in the target information group belongs to the target information category. By use of the method, the technical problem of low efficiency for obtaining the answering information in the relevant art is solved.

The invention discloses an urban environment quantized data organization method represented by vectors and grid hybrids, which includes that (1) construct a three-dimensional urban model; (2) the characteristic substances in the three-dimensional urban model is divided into two types including district environment and indoor architecture environment; for the district environment, precision setting is firstly made and then perform the division of map-layer, and present each divided map layer in a way of grid; for the indoor architecture environment, firstly perform the entity division on a semantic level and then perform the division of map-layer, and the map layer is presented in a way of vector; (3) map the grid-vector-based data map layers on the XML-based space objects one by one, the simulation application of the upper layer is actuated as the description above, and the characteristic substances act as query units so that the related environment information can conveniently be found out. The invention effectively avoids the drawbacks of using grids to describe the properties of urban environment such as large data amount and low precision, and at the same time expands the traditional two-dimensional description of environment information to the three-dimensional so as to be applied to the interactive simulation of the three-dimensional city.
