1. A method of managing aircraft service information, comprising: collecting unstructured field service narrative data utilizing self-training natural language processing algorithms; performing a lexical analysis on the collected field service narrative data to identify the lexical class of each of a plurality of parts of speech existing therein; parsing the collected field service narrative data based at least in part on the identified lexical class of each of the plurality of parts of speech; extracting problem data from the narrative data based at least in part on the lexical analysis; extracting solution data from the narrative data, wherein at least one of extracting problem data and extracting solution data is performed on the 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; and populating an aircraft service information database with the extracted problem data and the related extracted solution data.
