A natural language understanding (NLU) framework includes a lookup source framework that enables the lookup sources to be created and applied to understanding utterances. Each lookup source is associated with a respective lookup source template that defines the compile-time and inference-time behavior of the lookup source. For example, a lookup source template indicates which plugins are used by the lookup source, and may define property values that determine the operational behavior of each of these plugins during compile-time and/or inference-time operation of the lookup source. The lookup source framework includes a template manager that manages lookup source templates and determines a suitable lookup source template for each lookup source. The lookup source framework includes a lookup source template optimization subsystem that can apply a suitable optimization plugin to automatically determine attribute values to be included in an optimized lookup source template of a lookup source of the lookup source system.

System and method for managing and optimizing lookup source templates in a natural language understanding (NLU) framework

In various embodiments, a process for providing an automation discovery platform includes obtaining training data indicating conversation utterances and labels that are associated with the conversation utterances, where each of the labels of at least a subset of the labels corresponds to a virtual agent automation topic. The process includes obtaining a language machine learning model, where the language machine learning model has been trained to a first trained state using unlabeled data. The process includes updating the language machine learning model from the first trained state to a second trained state by applying the training data to the language machine learning model, where updating the language machine learning model includes generating an automation discovery model configured to provide outputs corresponding to virtual agent automation opportunities.

Automation discovery platform

A natural language understanding (NLU) framework includes a lookup source framework, which enables a lookup source system to be defined having one or more lookup sources. Each lookup source of the lookup source system includes a respective source data representation that is compiled from respective source data. For example, a source data representation may include source data arranged in a finite state transducer (IFST) structure as a set of finite-state automata (FSA) states, wherein each state is associated with a token that represents underlying source data. Different producers can be applied during compilation of a source data representation to derive additional states within the source data representation from the source data. Certain states of the source data representation that contain sensitive data can be selectively protected through encryption and/or obfuscation, while other portions of the source data representation that are not sensitive may remain in clear-text form.
