摘要

PROBLEM TO BE SOLVED: To provide a hyperspherical space language model generation technique capable of performing information search with higher performance.SOLUTION: A hyperspherical space language model generation apparatus comprises a hyperspherical space language model transformation part 11 allocating a size-1 continuous value vector to each token included in a document that is input by using a predetermined token continuous value vector transformation model and generating a hyperspherical space language model of the document by using the allocated size-1 continuous value vector.SELECTED DRAWING: Figure 1
