Claims (9)

From the data analyst explanatory variables, one or more of the constraints information used was formally described as decisions when selecting the attribute used to analyze, and one or more explanatory variables, one or more eyes variables And a reception unit for receiving
An analysis unit that analyzes data with respect to an attribute included in a selection pattern of one or more attributes satisfying the constraint determined from the explanatory variable;
Data analysis device comprising: A generation unit configured to generate a logical expression for generating a selection pattern for generating the selection pattern from the constraint that is valid;
The data analysis device according to claim 1, further comprising: an acquisition unit that acquires the selection pattern that satisfies the selection pattern generation logical expression.   The data analysis apparatus according to claim 1, further comprising: a display unit that displays a list of hypotheses derived by the data analysis based on the selection pattern selected by the data analyst from the list of selection patterns.   The type of the constraint is selected as the attribute to be used for the analysis, a removal constraint not selecting the attribute included in the target attribute of the constraint, and the attribute of the designated amount among the attributes included in the target attribute Constraint, exclusive constraint that selects 0 or 1 attribute from the target attribute, and incidental constraint that all target attributes are selected together when all the premise attributes that are the same as the target attribute are used The data analysis device according to claim 1.   The data analysis device according to claim 4, further comprising a statistical analysis unit that generates the removal constraint based on an appearance frequency that is a result of statistically analyzing the explanatory variable.   The data analysis device according to claim 4, further comprising: a statistical analysis unit that generates the exclusion constraint based on the correlation between the attributes.   The data according to claim 4, further comprising: a history analysis unit that generates the incidental constraint from a combination of values of propositional variables that make the unselected pattern generation logical expression for generating the selected pattern not yet selected true.
