Creating Aviation Safety Dictionary through Analysis

Since the aviation safety information contains both structured and textual data, this paper proposed a strategy for creating aviation safety dictionary. It used the maximum match algorithm based on segmentation unit to obtain the candidate word set and adopted the mutually information to improve the word extraction accuracy in cooperation with domain specialists. Experiments showed that the created dictionary could achieve better accuracy rate than the general dictionary and this would enhance the quality of automatic analysis and the ease of comprehension of the analysis results.
