The Design And Implement Of Category Information Feature Model

Classification information category feature model system is mainly used to classify the information.Each category in the model system could be classified into more detailed category(sub-category).Every category has its own feature,which is abstracted through the information of this category.And each feature has lots of feature-values.Every city could set its own category and retrieve the classified information according to the label.Meanwhile,label retrieval can be mapped to a category or property.This paper focuses on the service-layer's realization of classification information category feature and property features on classified information platform and its large-internet information platform.This paper detailed analysis the status and needs of internet information platform for the category and attribute characteristics,and the problems it faces.This paper designed and implemented a complete system,which could adapt category and attribute data model of large Internet classified information platform,designed and implemented the background management system of categories and attributes,designed and implemented a service-layer system,which could provide effective and reliable class attributes for large scale platform application scenarios,resolved and realized the architecture and core algorithm at the condition of high traffic and high concurrency,realized the problem of expanding the information category and attribute characteristics quickly and effectively at the condition of flexible business operations,and the urban landmark could be increased automatically.Resolved and realized the relational model,which is linkage between the classes and attribute information.
