摘要

PPROBLEM TO BE SOLVED: To provide a language analysis model learning technique for learning a series structure predictor capable of increasing the performance of predicting a language analysis model inexpensively. PSOLUTION: A language analysis model learning device 2 comprises a generative model learning means 21 for learning a learned discriminative model parameter vector set and a model integration parameter set by means of unlabeled data DSBu/SBto determine a generative model parameter vector set that maximizes a first objective function, a model integration learning means 22 for learning the discriminative model parameter vector set and generative model parameter vector set by means of labeled data DSBl/SBto determine a model integration parameter set that maximizes a second objective function, and a convergence determination means 23 for outputting the generative model parameter vector set and model integration parameter set when the generative model parameter vector set and model integration parameter set are determined alternately until either satisfies a convergence condition.
