METHOD, DEVICE, AND PROGRAM FOR LANGUAGE PROBABILITY CALCULATION

摘要

PROBLEM TO BE SOLVED: To appropriately predict the next word by effectively utilizing information of a long text, that is, a topic and a style of the sentence, a word peculiar to a speaker and a way of speaking or the like.SOLUTION: A language probability calculation device 1 sequentially reads a vector showing a symbol, and calculates an activity vector of an input layer for each reading, and every time the activity vector of the input layer is calculated, the activity vector of the intermediate layer is calculated based on the activity vector calculated last time in the intermediate layer and the activity vector of the input layer. At this time, the language probability calculation device 1 calculates an average activity vector which is an average of the activity vector calculated previous to the prescribed number of times from among the activity vectors of the intermediate layer, and every time the activity vector of the intermediate layer is calculated, the activity vector of an output layer is calculated based on the activity vector of the intermediate layer and the average activity vector of the intermediate layer, and an appearance probability of the symbol is calculated based on the activity vector of the output layer.SELECTED DRAWING: Figure 4
