Embodiment Construction

[0050] A method for constructing an address model provided by the present invention, as well as a method and system for address matching are described in detail below with reference to the accompanying drawings.

[0051] Such as figure 1 As shown, a method for constructing an address model provided by the present invention includes the following steps:

[0052] Step 101: Define the description granularity of the address.

[0053] In this embodiment, the description granularity of the address can be divided into three levels, that is, the place name of the administrative area, the name of the street / community / signature, and the address of the gate (gate number) / name of the unit.

[0054] Usually, the place name of the administrative area refers to the textual description of the standard name of the administrative area (administrative jurisdiction, for a city, including city-level, county-level, township-level administrative division range). For example, "Beijing", "Haidian Di...

Abstract

The invention provides an address model constructing method. The method comprises the following steps of: A, defining description granularity in different levels for an address; and B, combining and constructing address models according to the description granularity in the different levels. In an address matching method for the address models, an address element library is established according to the address models. The method comprises the following steps of: M, acquiring addresses to be matched; N, performing participle processing on the addresses to be matched to generate different address elements; and O, matching the different address elements in the address element library through logical operation. The invention also provides an address matching system, which comprises a terminal, the address element library, a comparison table database and an operation server. By the methods and the system, the effective matching and space orientation of address information in various presentation modes are realized.

Description

technical field [0001] The invention relates to the field of geographic information expression, in particular to a method for constructing an address model, and a method and system for address matching. Background technique [0002] Address information is ubiquitous in social activities, just like air and water, which are indispensable to human life. According to statistics, 80% of information is related to space, and the main link of the relationship is address information. This information involves almost all government departments, enterprises and public institutions, and the public, such as public security household registration, civil administration place names, national land registration, industrial and commercial taxation legal entities, comprehensive department statistics, etc., all of which contain address information. [0003] At present, although the address description information has been digitized, the lack of spatial positioning affects the efficiency of mana...
