Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] see Figure 1 to Figure 3 , the figure shows the present invention based on keyword co-occurrence utility gallery fault analysis method, including the following steps:

[0032] Step 1: Construct a custom dictionary based on the general dictionary and covering proper nouns and technical terms in the pipe gallery industry;

[0033] Step 2: After obtaining the fault information, perform fault information preprocessing on the fault information. The fault information preprocessing includes:

[0034] S2.1: Deduplication of fault information: If the fault information contains Chinese information and English information, compare and deduplicate the Chinese information and English information, and record the deduplicated fault information;

[0035] S2.2: Generate a word set: In the custom dictionary, use the word segmentation algorithm to segment the fault information ...

Abstract

The invention discloses a pipe gallery fault analysis method based on keyword co-occurrence. The pipe gallery fault analysis method comprises the following steps that 1, constructing a self-defined dictionary which is based on a general dictionary and covers special nouns and special terms of the pipe gallery industry; 2, after the fault information is obtained, carrying out fault information preprocessing on the fault information; 3, after a word set is obtained, conducting keyword selection on the word set; and step 4, after carrying out word cloud visualization on the keywords, forming a keyword co-occurrence matrix and visualizing the keyword co-occurrence matrix. According to the method, fault keywords are found by means of self-defined dictionaries and word frequency statistics, andare displayed through keyword word cloud visualization; furthermore, a keyword co-occurrence network is constructed, and layout optimization is carried out by adopting a graph layout algorithm, so that analysis and visual display of fault information are achieved.

Description

technical field [0001] The invention relates to a method for analyzing the failure of a pipe gallery based on the co-occurrence of keywords. Background technique [0002] Text analysis technology refers to the representation of text and the selection of feature items, which is a basic problem in text mining and information retrieval. It converts the unstructured original text into structured information that can be recognized and processed by the computer, thereby establishing a mathematical model to describe and replace the text, and finally achieve the purpose of mining effective information from a large number of texts. Keyword co-occurrence network analysis, also called co-word analysis, is a text content analysis technology. It reveals the relationship between keywords by analyzing the co-occurrence of words or noun phrases in the same text topic. The higher the value, the stronger the correlation between the two keywords. [0003] Graph layout algorithm is an algorit...
