Method and device for analyzing text to key value pairs

Abstract

The invention provides a method and a device for analyzing text to key value pairs. The methods mainly includes presetting a text analyzing template of text formats; using the text analyzing template for describing formats of text to be processed and formats of target key value pairs; compiling the text analyzing template of the text formats to acquire compiled results recognizable to computer programs; matching in the text to be processed according to source variable and separators to acquire value of the source variable; reserving the source variable the same with target variable and corresponding value as key value pairs corresponding to the text to be processed. The compiled results include the source variable and the separators corresponding to the text formats to be processed. The method and the device can improve efficiency of analyzing the text to the key value pairs.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and device for parsing text into key-value pairs. Background technique [0002] Key-value (Key-value) pair is a data storage structure of computer programs, which can quickly and uniquely locate a key-value (value) through a primary key (key), in scenarios that require fast search and one-to-one data storage has been widely used. [0003] In practical applications, there is often a need to extract valuable information from a piece of text and store it in the form of key-value pairs. For example, the text to be processed is "icbc001,123456", which hides information such as channel number (api) and serial number (no), and needs to be extracted to form the following key-value pair {api:icbc001,no :123456}. [0004] By analyzing the format of the text to be processed, it can be known that the text is a character string separated by a predetermined symbol...

AI Technical Summary

Problems solved by technology

[0010] To sum up, the existing method of parsing text into key-value pairs needs to search the text character by character to determine the text format, and after the search, it is necessary to determine the variable format according to the complex text format, and then after determining the variable format , it is necessary to extract the strings corresponding to these variables, and then assign them to form key-value pairs, that is, the existing method of parsing text into key-value pairs requires many times of full traversal

However, when the text format is very complex (for example, with multiple delimiters), and the text length is very long (for example, the length of the substring is very long), multiple full traversals will lead to a significant drop in parsing efficiency
