1. A method of managing aircraft service information, comprising:

  • collecting, by a processor, unstructured field service narrative data from a field service report utilizing self-training natural language processing algorithms;

    extracting, by the processor, problem data from the narrative data;

    extracting, by the processor, solution data from the unstructured field service narrative data, wherein extracting solution data is performed on the unstructured field service narrative data automatically by machine, such that a text representation of the narrative data is processed by machine to distinguish and parse at least one of problem data and solution data from the narrative by the self-training natural language processing algorithms;

    tokenizing, by the processor, the extracted solution data to create word tokens;

    electronically tagging, by the processor, semantic descriptors to the word tokens;

    populating, by the processor, an aircraft service information database used in servicing an aircraft with the extracted problem data, the related extracted solution data, and the semantic descriptors;

    querying, by a terminal, the populated problem data;

    searching, by the processor, the populated problem data queried by the terminal from the aircraft service information database;

    retrieving, by the processor, the related populated solution data from the aircraft service information database;

    sending, by the processor, the related populated solution data to the terminal accessed by the user; and

    displaying, by the terminal, the related populated solution data.
