A user profile model for intelligent delivery of spatial information

摘要：

Conventional spatial information delivery is system-oriented,and users have to adapt to the system and complete the delivery of spatial information.Two disadvantages exist in the delivery service mode:(1) users personalized requirements cannot be satisfied;(2) Initiative delivery service cannot be provided for users.In this paper,we firstly classify conventional user profile models into four categories.After analyzing the limitations of these user profile models,we conclude that conventional user profile models are not suitable for the application of spatial information intelligent delivery.Then,aiming to the objectives of spatial information intelligent delivery,we propose a user profile model of spatial information,and give the building method of the model.Also,we put forward a similarity measure method between spatial information and user profile.In order to verify the availability of the user profile model,we present an example of spatial information intelligent delivery.The experimental results show that the proposed user profile model can reflect user profile quite well.
