Embodiment

[0044] figure 1 It is a flow chart of a user geographic information analysis and text mining research method based on natural language processing provided by an embodiment of the present invention. To execute, the device may be implemented in software and / or hardware. refer to figure 1 , the method may specifically include the following steps:

[0045] S101. Obtain an input address statement.

[0046] Specifically, in the process of calculating the similarity of address sentences, sentences need to be segmented, and similarity calculations are performed on the segmented word vectors. For example, each link in the similarity calculation process can be modularized to construct An available address similarity calculation subsystem, the input data are two address sentences described in Chinese and English respectively. Therefore, firstly, the input address statement is acquired, and the acquisition method may be active acquisition, or periodic reception, etc., which is not lim...

Abstract

The invention relates to a user geographic information analysis and text mining research method and device based on natural language processing. The method comprises the steps of obtaining an input address statement; if the address statement is an English address statement, performing word segmentation processing to obtain a word vector of the English address statement, and translating each word element in the word vector according to a pre-constructed translation dictionary to convert each word element into a pinyin character string of the corresponding Chinese vocabulary; for the pinyin character string, generating a corresponding weight distribution rule according to a pre-calculated word element index vector so as to determine a weight vector; calculating the similarity of any two address statements according to the weight vector and the existence vector of the word element so as to determine a target address statement; and analyzing the geographic information of the user and mining the corresponding text information by applying the target address statement. Therefore, the geographic information analysis of the user can be fully analyzed to fully reflect the community characteristics of the user.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a user geographic information analysis and text mining research method and device based on natural language processing. Background technique [0002] With the advancement and development of science and technology, the application of big data is becoming more and more extensive. The most notable feature of the era of big data is the sharp increase in the amount of informational data in the entire society. The geographical information of the user reflects the user's residential address, mailing address and real-time address, etc., among which the residential address and mailing address can reflect the user's residential information, and can be obtained by analyzing the user's IP address (Internet Protocol Address, also translated as Internet Protocol address). The real-time address reflects the location information when the user initiates the demand. With the rapid...
