Abstract: An analysis apparatus is connectable to a terminal capable of displaying web pages by accessing a web server capable of executing a web application. The analysis apparatus comprises a processor, a memory and an interface. The processor is configured to perform the following processing of: receiving at least one log concerning the web application stored in the terminal from the terminal via the interface; acquiring a plurality of kinds of use condition feature values based on the log received, the plurality of kinds of use condition feature values being information characterizing conditions of use of the web application; analyzing whether a correlation exists between a first kind of use condition feature values and a second kind of use condition feature values in the plurality of kinds of use condition feature values acquired in the processing of acquiring; and outputting an analysis result obtained by the processing of the analyzing.

Abstract: Provided is a computer system to present information useful for achieving purposes related to an object by utilizing AI prediction. The computer system manages a prediction model for predicting an object event based on evaluation data and feature profiling database that defines a change rule of each of the plurality of feature values included in the evaluation data, generates change policy data by changing the plurality of feature values included in the evaluation data based on the feature profiling database, calculates an evaluation value indicating effectiveness of the change policy data, and generates display data for presenting the change policy data and the evaluation value as information useful for achieving purposes related to the object.

Abstract: Fairness of automated assessments of AI has become a significant issue in recent years, and techniques for adjusting assessment results are being sought. This information processing system is configured to include: a first predicting unit which outputs an assessed value from input information that does not include sensitive attribute information a user has decided is not to be input; a second predicting unit which has been trained in advance, using teacher data, to estimate the sensitive attribute information that the user has decided is not to be input, and which estimates the sensitive attribute information from the input information that does not include the sensitive attribute information; and a first quantizing unit which, on the basis of the estimated value of the sensitive attribute information obtained from the second predicting unit, adjusts the assessed value output by the first predicting unit, and outputs an assessment result.
