Training data including a first and second group of questions each associated with an answer is read into memory by a computer. A class of answers including the answer to a question for each question is determined, where each class of answers has a class label that is associated with each of the questions, and each of the questions are classified into a respective class of answers, accordingly. First and second training data is generated including the first and second groups of questions and corresponding classes of answers for use in first and second classifiers, respectively. Each question of the first and second group of questions is classified by the second and first classifiers, respectively, where the classifying generates corresponding classification results. The first or second training data is updated based on the classification results to generate corresponding updated first or second training data, respectively.

Techniques for automatically generating test data solve various problems in test data generation. A technique of automatically generating test data includes receiving a signature to be embedded in at least one character string to be generated and determining a total sum of attribute values intrinsic to characters in the character string. The sum is associated with each element of the signature. At least one of the characters in the character string may be selected from a character table describing characters prepared to create the test data so as to achieve the determined total sum for each element of the signature. The generated test data contains the character string including the selected character.
