Embodiment 1

[0113] The specific execution steps of an experimental system are:

[0114] (1) Spatial information metadata registration

[0115] The spatial information registration center is the intermediary between spatial information data providers and data users. It registers the metadata of each data center to the spatial information registration center, and uses the spatial information registration center to manage these metadata records. The database of the registration center uses Oracle database.

[0116] (2) Collection of spatial information user data sources

[0117] User registration data and query data are recorded in XML files as a data source for spatial information user modeling. Users register before logging in to the spatial information distribution experimental system. The registration information includes user unique identifiers, names, ages, etc.; in the system In the process of use, query the spatial information.

[0118] (3) Spatial information user mode...

Abstract

The invention discloses an active individualized distribution method of spatial information, which is realized by constructing a spatial information user model, establishing and filtering a distribution candidate set, and solving a distribution decision set. A method for establishing a spatial information user model provided by the present invention is realized through four steps: query decomposition, weight value calculation, distribution feature value calculation, interest degree and rule establishment; establishing and filtering distribution candidate sets through the spatial information user model It is realized by the interest degree and rule filtering; the solution of the distribution decision set is realized by the utility calculation method which takes into account the distribution eigenvalues. The beneficial effects of the present invention are: by establishing a spatial information user model, an active spatial information personalized distribution method is realized.

Description

technical field [0001] The invention belongs to the field of information, and in particular relates to an active personalized distribution method of spatial information. Background technique [0002] Spatial information distribution is the process of delivering spatial information from data sources to users. [0003] The current distribution of spatial information is mainly based on the query conditions provided by users, and the distribution process of spatial information is completed through query and download. [0004] This kind of distribution mode, which searches for relevant content that meets the conditions according to the query instructions proposed by the user, and organizes the retrieval results and returns them to the user, has the following specific problems: [0005] 1. Different spatial information cannot be interconnected and shared; [0006] 2. It is inconvenient to use, users cannot obtain multiple types of information at one time according to application...
