Problems solved by technology

[0003] The analysis of traditional aviation safety reports is mainly to conduct simple queries and statistics on the structured data; while for the unstructured part of the report, that is, the part that contains a large amount of textual descriptions of the accident process and possible causes, due to Experts in the aviation field need to spend a lot of time and energy on analysis and research, which will be greatly restricted by human, material and financial resources, and only a small part can obtain effective analysis results; in addition, the accuracy and reliability of manual analysis of these unstructured data is still limited. Rely heavily on the analyst's expertise and experience
With the passage of time, aviation safety reports have been accumulated day by day, and millions of safety reports of various types have been collected, seriously exceeding the carrying capacity of professional analysts

Embodiment 1

[0066] Such as figure 1 As shown, it shows a flow chart of the steps of the information processing method of the application for the narrative text of the aviation safety report, and the method may specifically include the following steps:

[0067] The aviation safety report released by the aviation safety reporting system ASRS of the FAA of the Federal Aviation Administration of the United States contains a large number of structural parameters, such as airports, aircrafts, and environmental information. The detailed text description of security incidents is the key data in the classification of research security reports. Because the narrative text in the report is affected by the educational level and job differences of the personnel submitting the report, there are many spelling mistakes and field abbreviations. Therefore, in order to achieve the purpose of extracting and synthesizing effective information and discarding useless information, this application Firstly, the a...

Embodiment 2

[0149] Such as Figure 5 As shown, based on the same inventive concept, it shows a structural block diagram of the information processing device for the narrative text of the aviation safety report in this application, and the device may specifically include the following modules:

[0150] The report preprocessing module 501 is used to preprocess the narrative text of multiple aviation safety reports to obtain a word corpus for the multiple aviation safety reports;

[0151] The corpus training module 502 is used to use the document topic generation model LDA to train the word corpus to obtain topic vectors And utilize typical distributed word vector word2vec tool to train described word corpus, obtain the first word vector

[0152] Vector conversion module 503, used to convert the subject vector and the first word vector Convert to the same vector space to get the second word vector based on the document

[0153] Topic distribution calculation module 504, for the se...

Abstract

The invention provides an information processing method and device for an aviation safety report narrative text. The method comprises the following steps: firstly, preprocessing narrative texts of a plurality of aviation safety reports to obtain a word corpus; respectively training the word corpus by utilizing an LDA model and a word2vec tool to obtain the topic vector and the first word vector, and then carrying out procressing to obtain a second word vector based on the document, and calculating topic distribution of the word corpus according to a loss function of the lda2vec model; evaluating the topic distribution of the word corpus by utilizing topic coherence indexes; and finally outputting a topic interpretability result of the word corpus, thereby realizing topic modeling for a large-scale aviation safety report narrative text, and identifying a reported topic so as to reduce dependence on aviation field experts and related workloads.

Description

technical field [0001] The present application relates to the technical field of aviation safety, in particular to an information processing method for the narrative text of the aviation safety report and an information processing device for the narrative text of the aviation safety report. Background technique [0002] Safety has always been the lifeline of the air transport industry. Only by accurately discovering and correcting the defects in the system in advance and controlling and eliminating aviation safety hazards can we actively prevent flight accidents and ensure flight safety. Aviation Safety Reporting System ASRS (Aviation Safety Reporting System) is a safety voluntary reporting system established by the Federal Aviation Administration FAA (Federal Aviation Administration). , security personnel, and other relevant personnel) voluntarily and anonymously submit unsafe incidents and potential safety hazard reports regarding unsafe incidents involving aircraft operat...
