PINNING ARTIFACTS FOR EXPANSION OF SEARCH KEYS AND SEARCH SPACES IN A NATURAL LANGUAGE UNDERSTANDING (NLU) FRAMEWORK

Abstract:

Present embodiments include an agent automation framework having an artifact pinning subsystem that pins meaning representations of a search space to enable the agent automation system to target particularly relevant candidates for improved inferences. To generate the search space, the artifact pinning subsystem may determine multiple understandings of sample utterances within intent-entity models to generate meaning representations. The sample utterances generally each belong to an identified intent that may have been labeled with a particular entity, within a structure defined by the intent-entity models. To validate the relevance of each meaning representation for an identified intent, the artifact pinning subsystem may pin meaning representations that include the particular intent and include a respective entity corresponding to the labeled entity. In addition to model-based entity pinning, the search space may also be generated with respect to a contextual intent of an on-going conversation between a user and a behavior engine.
