Spatial information user modeling method from the point of view of linguistics

Given that conventional spatial information user profile models have not a clear classification because of lack of theoretical basis, the comprehensive information theory is introduced into spatial information use profile modeling area. From the point of view of linguistic, the classification method of user profile models based on comprehensive information theory is proposed in this paper. According to syntactic, semantic and pragmatic information, user profile models are classified into four categories: syntactic information based models, semantic information based models, pragmatic information based models and composite elements based models, which make a clear distinction of the classification of user profile models. Based on these researches, the adaptability of all models respectively is analyzed in-depth, and the application conditions of every kind of user models are pointed out definitely.
