Embodiment

[0048] Example: such as figure 1 As shown, the construction method of the emergency knowledge graph based on Chinese word segmentation technology specifically includes the following steps:

[0049] S1: input emergency information text;

[0050] S2: Analyzing the elements in the emergency information text in the step S1, extracting key data, and using the extracted key data to construct an emergency knowledge base; the emergency knowledge base in the step S2 includes a feature lexicon of emergency elements and emergency elements standard database;

[0051] Such as figure 2 As shown, the word segmentation text content can be roughly divided into three types according to the type of Chinese text: article type, sentence type and vocabulary type; different methods are provided for different types of text to analyze and process natural language, such as vocabulary type and sentence type The text of the text mainly uses syntax analysis, syntax analysis, part of speech analysis, n...

Abstract

The invention discloses a method for constructing an emergency knowledge graph based on a Chinese word segmentation technology. The method specifically comprises the following steps: S1, inputting anemergency information text; S2, analyzing elements in the emergency information text in the step S1, extracting key data, and constructing an emergency knowledge base by utilizing the extracted key data; S3, performing word segmentation and judgment on the emergency information text input in the step S1 by adopting a multi-strategy combined Chinese word segmentation algorithm, and outputting a word segmentation result; S4, searching and matching the word segmentation result obtained in the step S3 in the emergency knowledge base by utilizing a retrieval engine, and outputting result data afterthe matching is successful; and S5, constructing an emergency knowledge graph according to the emergency service system in combination with the result data, and outputting graph result data. A scientific and comprehensive emergency knowledge graph is constructed according to an emergency business system, the data matching speed and the word segmentation precision are improved, the problems of lowretrieval efficiency and the like are solved, and the shared application service of emergency knowledge is realized.

Description

technical field [0001] The invention relates to the technical field of Chinese word segmentation, in particular to a method and system for constructing an emergency knowledge map based on Chinese word segmentation technology. Background technique [0002] According to the needs of national emergency information construction, it is urgent to summarize and classify all kinds of emergency information resources, and build a complete and standardized emergency knowledge lexicon, so as to form a knowledge map of the emergency industry and provide support for the shared application of emergency information. In view of the problems of low precision and slow matching in the current Chinese natural language processing and single Chinese word segmentation algorithm, using the word segmentation technology combined with multiple strategies can comprehensively use the advantages of each word segmentation technology, effectively make up for their disadvantages, and build a hierarchical Chi...
