Japan, Sept. 18 -- NIPPON TELEGR & TELEPH CORP ,TOKYO INSTITUTE OF TECHNOLOGY has got intellectual property rights for 'RHETORICAL STRUCTURE ANALYSIS LEARNING DEVICE, SYSTEM, PARAMETER OPTIMIZATION METHOD, AND PROGRAM.' Other related details are as follows:
Application Number: JP,2023-031747
Category (FI): G06F40/58,G06F40/216
Stage: PROBLEM TO BE SOLVED: To provide a rhetorical structure analysis learning device, a parameter optimization method, and a program that do not require preparing a large amount of raw text data as correct-answer data, without biasing parameter optimization at prior learning time.SOLUTION: In a system composed of a rhetorical structure analysis learning device and a rhetorical structure estimation device, the rhetorical structure analysis learning device for optimizing the parameters of rhetorical structure analysis comprises: a data extension unit that generates pseudo-training data by performing reverse translation on training data as correct-answer data consisting of a sentence after translation; a prior learning unit that generates a prescribed parameter by optimizing a randomly initialized parameter using the pseudo-training data; and an additional learning unit that generates a final parameter by optimizing the prescribed parameter using the training data, adopting the prescribed parameter as an initial value.SELECTED DRAWING: Figure 3 (Grant)
