Intention estimation equipment and intention estimation system
First Claim
1. An intention estimation device comprising:
- a processor; and
a memory connected to the processor, and storing a first training data group including a plurality of pieces of training data each being constituted by a text and a correct intention expression correlated with each other, and a second training data group including the plurality of pieces of training data in the first training data group and a plurality of pieces of training data not included in the first training data group,wherein the memory further stores instructions that, when executed by the processor, causes to processor to execute;
a model creation unit that creates a plurality of statistical models that, when text is input, estimate an intention of the input text using the training data and outputs an intention estimation result, and the statistical models include a first statistical model is created by the model creation unit using the first training data group and a second statistical model is created by the model creation unit using the second training data group,an error data extraction unit that extracts training data from the second training data group corresponding to text of which an intention estimation result output based on the first statistical model is correct and an intention estimation result output based on the second statistical model is erroneous, as error data;
an opposite data extraction unit that extracts, from the second training data group, training data that is a cause for an intention estimation result of the error data output based on the second statistical model becoming erroneous as opposite data; and
a data correction unit that performs correction of the second training data group so that an influence of the error data or an influence of the opposite data on creation of the statistical models is changed.

Abstract
An intention estimation equipment includes: a first training data group; a second training data group; a model creation unit that creates first and second statistical models that estimates an intention of an input text; an error data extraction unit that extracts, from the second training data group, training data corresponding to a text, of which an intention estimation result based on the first and the second statistical models is correct and erroneous, respectively, as error data; an opposite data extraction unit that extracts, from the second training data group, training data that is a cause for an intention estimation result of the error data based on the second statistical model becoming erroneous as opposite data; and a data correction unit that performs correction of the second training data group so that an influence of the error data or of the opposite data on creation of the statistical model is changed.
