Design of Keyword Extraction System for Aviation Safety Information Based on ArcGIS Technology

In order to save a lot of time and energy for civil aviation staff, but also improve work efficiency and ensure the quality of safe production, a keyword extraction system based on information security is designed. First, the safety information related to civil aviation is collected. The keyword extraction technology is performed for the collected information. The word segmentation and feature values are refined. Then, the extracted keywords are defined and classified , and a new keyword library is buildded. Finally, the visualization of keywords are upgraded. The time and space elements are added. and a method of combining graphics and text is adoptted. The experimental results show that this system is more helpful for information readers to read, understand and memorize about the subject of the entire information, thereby ensuring that civil aviation workers can work in an orderly and faster manner.
