摘要： PURPOSE: To provide a data analysis method capable of classifying plural rules generated by the instruction of a user from the data of a data base into the highly common rule groups of suitable data. CONSTITUTION: The rules for extracting the appearing area of a record provided with a predetermined feature from the records of the data base are generated and displayed for number given by the instruction of a user together with the adaptation of the rules in a rule form composed of a condition part provided with more than one record items and a conclusion part provided with one record item based on the instruction of the user (11). The degree of the similarity of the rule between the specified rule specified by the user and the other rules is obtained (20), the specified rule and the other rule provided with the degree of the similarity of the rule higher than the lowest degree of the similarity are displayed in a pair and registered based on the instruction of the user (30). Further, the rule is selected from the registered rules or a new rule is generated, the degree of the similarity between the respective pairs of the rules in the rules is obtained and displayed and the inclusion relation of a pair of the rules specified by the user is obtained and displayed (40).

摘要： PURPOSE: To shorten the working time for a data analysis by squeezing down many items of a data base on an analysis item, selecting a rule for analysis to be used for an analysis and outputting the rule. CONSTITUTION: An analysis item convergence part 112 calculates the dispersion and correlation coefficient of inputted object data and displays them through the screen of an analysis item selection part 131. A rule generation part 113 combines conditions in the range of a maximum condition number and performs a calculation by defining the rate of 'reactive' data contained in the data compatible to a rule as density. A rule evaluation part 114 performs the calculation by defining the rate of 'reactive' data compatible to the rules in a rule output order as a cumulative covering ratio and displays the transition graphs of the cumulative convering ratio and the density on the screen of a rule selection part 133. When the display range of the rule is inputted, the discrimination ratio of each condition of the rules, the predictive values of the density by the integrated value of the discrimination ratio of each condition are comapred, the rule in which the integrated value is large is emphatically displayed and the conditions are displayed in the higher discrimination ratio order of each condition.

摘要： PURPOSE:To decrease the burden of a user by dividing an inputted character string when the maximum number of stored characters is smaller than the number of the characters in the inputted character string to be a retrieve object, and indicating the retrieve of the maximally corresponding character string as one word. CONSTITUTION:When the character code string of an input character code storing part 1 matches with the word in a dictionary in a character code comparing part 3, the number of the maximally corresponding characters and an address in the dictionary are stored into a maximal length correspondence storing part 4. Based on the number of the characters stored into the storage part 4, a comparison objective character code control part 5 separates the character code string by using a partitioning code, and a comparative collating processing with a character code storage part 2 is executed again. That is, when the word to be the retrieve object of the input character string is not stored into the dictionary in an original form, the word to be the retrieve object, the number of the maximally corresponding characters and the address in the dictionary at such a time point are stored. Based on the information, by applying a control such as division to the word to be the retrieve object, the optimal word information stored into the dictionary can be obtained by binary search for one time.

摘要： PROBLEM TO BE SOLVED: To generate rules reflecting the characteristics of the entire data corresponding to rule generation conditions set by a user irrespective of the scale of analysis object data. SOLUTION: This method is constituted of a record extraction means 10 for randomly extracting the set of the records of the scale corresponding to the rule generation conditions determined beforehand from the analysis object data composed of the set of the records stored in a database 2, a rule generation means 20 for detecting the plural appearing areas of the records provided with features determined as the rule generation conditions from the randomly extracted set of the records and expressing the appearing areas as the rules composed of a condition part and a conclusion part and a rule evaluation means 30 for utilizing all the records of the analysis object data and evaluating the propriety of the areas expressed by the generated rules.
