Embodiment Construction

[0043] The BiLSTM-based automatic semantic verification method for land-to-air call repeat provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Such as figure 1 As shown, the BiLSTM-based automatic semantic verification method for land and air conversations provided by the present invention includes the following steps carried out in order:

[0045] Step 1) make land-air call repetition corpus;

[0046] Step 1.1) Convert the real land-air call recording into text form, and select the read-back type sentence pairs as the read-back sentence pairs of the land-air call, and each read-back sentence pair is the instruction sent by the controller and the pilot The read-back command is composed of these two sentences, and then it is stored in text txt format;

[0047] Step 1.2) According to the land-air call rules and relevant requirements in "Air Traffic Controller Radio Land-Air Call", ...

Abstract

The invention discloses a terrestrial-air conversation recitation semantic automatic verification method based on BiLSTM. The method comprises the following steps: making an air-ground communication recitation corpus; Preprocessing the corpus; The word vector sequences of the two statements in each recitation statement pair are input into two parallel BiLSTMs respectively, and outputs of the two statements at all moments are obtained; Matching the output vectors of the two BiLSTMs at each moment to generate a semantic matching matrix between the recitation statement pairs; K-Matching Matrix For Semantic Matching Max pooling processing is carried out to obtain first k matching features, and the matching features form a significant matching feature vector; And judging whether the two statements in the recitation statement pair are consistent or not. According to the method, the semantic feature advantage that the BiLSTM network can automatically learn the statement sequence is utilized,the expenditure of manually designing features can be avoided, and the BiLSTM network can extract more abundant context semantic features.

Description

technical field [0001] The invention belongs to the technical field of automatic verification of repeating semantics of land and air calls in civil aviation transportation, and in particular relates to a BiLSTM-based automatic verification method for repeating semantics of land and air calls. Background technique [0002] With the improvement of science and technology in modern society and the acceleration of social development, the air traffic flow has increased sharply, and the proportion of civil aviation transportation in people's production and life has continued to increase. Therefore, air transportation safety issues have become more and more popular. Pay attention to. In civil aviation transportation, the factors leading to accidents can be classified into three categories: natural factors, mechanical failures and human factors. With the development of science and technology, the incidence of flight accidents caused by natural factors and mechanical failures has bee...
