A prediction rationale analysis apparatus includes a prediction model that stores prediction models designed or trained to solve common problems, a prediction execution part that makes a prediction on the prediction target based on each prediction model to derive a model prediction result, a prediction rationale analyzer that identifies a set of prediction models based on which the model prediction result identical or approximate to the external prediction result is derived from the prediction target, and infers, as a prediction rationale for the external prediction result, a property common to the prediction models belonging to the set, and a prediction rationale difference analyzer that compares a property of any prediction model with the prediction rationale for the external prediction result to derive a prediction rationale difference indicating a difference in prediction rationale between the prediction model and the external prediction, and outputs information based on the prediction rationale difference.

Prediction rationale analysis apparatus and prediction rationale analysis method

The present invention has an object to analyze, regarding an existing system without a source code, the relationship between input items and internal system processing with respect to output items and present the analysis results to a user. An existing system processing specification extractor is an apparatus for making an existing system operate and analogizing input items of the existing system and internal system processing patterns without performing analysis of implementation and includes: an output data change information acquisition unit that classifies changes of output data associated with input to the existing system on the basis of types of changes of each output element; and an internal system processing specifying unit that combines the classifications obtained by making different input to the existing system and specifies a type of processing based on a usage pattern of an input item value.

Existing system processing specification extractor

A device and method automatically generate a program for buffering differences based on characteristics of a component. A buffer program for buffering differences of the way to use a component during different software environments is automatically generated. The device includes a controller for executing automatic generation of the buffer program, a memory including control information and a processing program, an input device for inputting the processing content of the component, and an output device for outputting the automatically generated buffer program. The memory records a plurality of forms for buffering the component as the control information and the controller extracts characteristic information based on the processing content of the component and records the extracted characteristic information as control information in the memory, selects a specified form based on the characteristic information, and generates the buffer program based on the selected form and the characteristic information.
