1. A system for analyzing language using supervised learning method, the system comprising: problem expression extraction processing means for extracting a portion matching with structures of preset problem expression from data not supplemented with information for an analysis target and taking the portion as a portion corresponding to problem expression; problem structure conversion processing means for converting the portion corresponding to problem expression into supervised data including a problem and a solution; machine learning processing means for extracting a set of a plurality of features and a solution from the supervised data, performing machine learning from the extracted set of features and solution, and storing a learning result in a learning result database; features extracting processing means for extracting features from object data inputted; and solution extrapolating processing means for a solution based on the learning result stored in the learning results database.
