Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: A dictionary used by a spoken language understanding (SLU) system is improved by providing weightings for entities in the dictionary that represent the likelihood each entity belongs to an entity class represented by the dictionary. A classifier model may be trained using a seed list containing sample entities that belong in the entity class and a background entity list containing samples that do not belong in the entity class. Clicked URLs from search logs, search result URLs, and attributes from an entity graph may be used as features of the sample entities to train the classifier model. The classifier model may be used to weight entities from a candidate dictionary. The entity weightings are used to generate an improved dictionary for use in the SLU system.
