Apparatus and method for model adaptation for spoken language understanding
First Claim
Patent Images
1. A method comprising:
- receiving a first language model for a first domain having a first training set;
based on a second language model, which is smaller than the first language model, selectively sampling training data associated with a second domain from a second training set, to yield sampled training data;
labeling, via a processor, the sampled training data, to yield second domain labeled data; and
concatenating, via the processor, the first language model by replacing a portion of the first training set in the first language model with the second domain labeled data.

Abstract
An apparatus and a method are provided for building a spoken language understanding model. Labeled data may be obtained for a target application. A new classification model may be formed for use with the target application by using the labeled data for adaptation of an existing classification model. In some implementations, the existing classification model may be used to determine the most informative examples to label.

8. A system comprising:
-
a processor; and a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising; receiving a first language model for a first domain having a first training set; based on a second language model, which is smaller than the first language model, selectively sampling training data associated with a second domain from a second training set, to yield sampled training data; labeling the sampled training data, to yield second domain labeled data; and concatenating the first language model by replacing a portion of the first training set in the first language model with the second domain labeled data. - View Dependent Claims (9, 10, 11, 12, 13, 14)
