The objective of this proposed work is to predict whether the airline crash has occurred due to a strike or not by using data mining techniques. Risk and safety are not always guaranteed within the field of aircraft. strikes are dangerous for aircraft due to the relative speed of the plane with reference to the . The characteristics of aircraft …

Thus, this study combines machine learning-based text mining with GCV-LIME to identify likely causality factors for injury severities while providing interpretability as required by traffic safety analysts. Data for heavy vehicle crashes collected from 2007 to 2017 in Queensland, Australia, were used to evaluate the proposed approach.

Formally, accuracy has the following definition: Accuracy = Number of correct predictions Total number of predictions. For binary classification, accuracy can also be calculated in terms of positives and negatives as follows: Accuracy = T P + T N T P + T N + F P + F N. Where TP = True Positives, TN = True Negatives, FP = False Positives, …

China. On 23 July 2022, ten people were killed, and seven were injured, when a mine in northwest China collapsed. According to state-run news channel CCTV, a part of a mountain near the mine caved in Gansu province, burying workers and cars. In December 2022, a similar collapse occurred in China's southwest Guizhou province.

Further, the authors did not consider an analysis of factors associated with different injury severity levels, nor contexts provided by multiple sentences. In a recent study, Zhang et al. (2019) used text mining on traffic crash narratives to predict secondary crashes. A comparison of four machine-learning techniques was performed.

Crashes at this level are thinly scattered — the average annual odds of a crash in a 5x5 grid cell is about one-in-1,000 — and they rarely happen at the same location twice. Previous attempts to predict crash risk have been largely "historical," as an area would only be considered high-risk if there was a previous nearby crash.
