The project aims at building a data lake providing a comprehensive set of analytical tools for an R&D team of Amadeus, the leader IT provider for the travel industry. The system targets different data sources related to the reissue of a flight ticket, which are processed to achieve three main objectives: a search engine, a statical framework and a business intelligence tool. The previous goals are mapped to three different tasks: the development of an efficient preprocessing phase, the proper organization of the storage and the graphical user interface, and the elaboration of a machine learning solution. One of the main contribution is the use of the current state of the art technologies in terms of scalable data processing and data storage.
