Abstract: 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. In particular, taxonomy lookup sources can be compiled from suitable taxonomy source data that represents relationships between various entities within a domain of a client. These taxonomy lookup sources can extract taxonomy segmentations from utterances, such as received user utterances and sample utterances of an intent-entity model. The taxonomy segmentations can then be leveraged by the NLU system to perform vocabulary injection to expand the number of meaning representations in the utterance meaning model and/or the understanding model, increasing the likelihood of matches being located during a meaning search operation. Additionally, the taxonomy lookup sources can be leveraged by the NLU system to enable validation of sample utterances submitted for inclusion in the intent-entity model.

Abstract: Workflows can be refactored using a visual workflow model, such as within a virtual programming environment. A selection of a group of activities in an existing workflow can be received. The group of activities can be duplicated into a new workflow. Thereafter, the group of activities can be parsed to identify at least one input variable used by the activities of the group and at least one output variable resulting from those activities. The input variables and output variables are then duplicated as inputs and outputs to the new workflow. The previously selected group of activities can be replaced in the existing workflow with an activity based on the new workflow. The input variables and output variables are then mapped to the respective inputs and outputs of that activity.
