Abstract


Problem solving, referred to as case-based reasoning (Case-Based Reasoning CBR) as a traditional field of artificial intelligence methods based on similar reasoning, with the knowledge or information of past cases similar case, since the 1990s increasingly more attention. The same time, due to the rapid development of the complex characteristics and geography geoscience issues, case-based reasoning has been applied to the field of geographic Case-Based Reasoning. Retrieval of similar cases in the process of case-based reasoning is the key to solving the case-based reasoning, geographic case similarity calculation most traditional CBR similarity calculation method for spatial attributes characteristics, there are some scholars in the case of similarity calculation process consider spatial relationships or spatial form. Geography Case not only has its own spatial characteristics of complex spatial relationship between the case and the case, and the case occur geospatial certain spatial patterns. These characteristics is not considered in the traditional geographic case similarity calculation to or considered not very full, Based on this article the case of geographical space similarity calculation deeper research, mainly including: (1) from the concept on the analysis of the geographic Case-Based Reasoning different reasoning with the ordinary case, pointed out that the geographical case similar to the specificity and complexity from concept to define the meaning of the geographical case spatial similarity calculation. (2) analysis of the CBR similarity calculations commonly used algorithms. Geographical case is also a case of a traditional case similarity calculation, there must be suitable for the part of the similarity calculation of Geography Case, by analyzing the similarity computing space the CBR similarity algorithm will be applied to the introduction of geographical case, and targeted The conduct of the supplement and improve. (3) spatial reasoning is also important areas of artificial intelligence research, its space similarity calculation is an important research component, by analyzing the the GIS spatial similarity calculations, spatial relations and spatial patterns of geographic case similarity calculation method. (4) by analyzing the CBR similarity calculation and GIS space similarity calculation, summarizes the geographic case the similarity calculation of algorithm model, and Visual C # and ArcEngine the development of the one used in geography case space similarity calculation of the system, this article The algorithm is validated.
