Information processing apparatus, information processing method and information processing program

An information-processing apparatus comprising:

• an input unit that inputs text data;
• a text-data-memory unit that stores said text data;
• a word-cutting unit that executes a word-cutting process on said text data;
• a syntax-analysis unit that performs a syntax-analysis process on said text data on which said word-cutting process was performed;
• a thesaurus-creation unit that creates thesauruses from said text data on which said syntax-analysis process was performed;
• a thesaurus-memory unit that stores said thesauruses created by said thesaurus-creation unit;
• a thesaurus-sorting unit that performs a sorting process on said text data on which said word-cutting and said syntax-analysis were performed;
• a sorting-results-memory unit that stores the sorting results from said thesaurus-sorting unit;
• a frequency-of-appearance-calculation unit that calculates the frequency of appearance for each thesaurus based on said sorting results stored by said sorting-results-memory unit;
• a frequency-of-appearance-memory unit that stores the results calculated by said frequency-of appearance-calculation unit;
• a correlation-coefficient-calculation unit that calculates correlation coefficients between thesauruses;
• a correlation-coefficient-memory unit that stores the correlation coefficients between thesauruses that were calculated by said correlation-coefficient-calculation unit;
• a correlation-coefficient-total-calculation unit for each thesaurus that calculates the total of the correlation coefficients for each thesaurus;
• a correlation-coefficient-total-memory unit for each thesaurus that stores the total of the correlation coefficients for each thesaurus calculated by the correlation-coefficient-total-calculation unit for each thesaurus;
• and
• a graph-creation-display unit that creates and displays a graph based on the frequency of appearance stored by the frequency-of-appearance-memory unit and the correlation-coefficient totals for each thesaurus stored by the correlation-coefficient-total-memory unit for each thesaurus;
• and wherein
• said word-cutting unit and said syntax-analysis unit perform said word-cutting process and said syntax-analysis process again based on said thesauruses created by said thesaurus-creation unit.
