Machine learning based tenant-specific chatbots for performing actions in a multi-tenant system
A multi-tenant system performs custom configuration of a tenant-specific chatbot to process and act upon natural language requests. The multi-tenant system configures the tenant-specific chatbots without requiring tenant-specific training. The multi-tenant system providing a user interface for configuring a tenant-specific set of permitted actions. The multi-tenant system determines a set of example phrases for each of the selected permitted actions. The multi-tenant system receives a natural language request from a user and identifies the action that the user wants to perform. The multi-tenant system uses a neural network to compare the natural language request with example phrases to identify an example phrase that matches the natural language request. The multi-tenant system performs the action corresponding to the matching example phrase.
1. A computer implemented method for enabling custom configuration of a tenant-specific chatbot to process and act upon natural language requests without requiring tenant-specific training, the method comprising:
providing a user interface displaying a set of actions;
receiving a selection of one or more actions from the set of actions;
configuring the selected one or more actions as a tenant-specific set of permitted actions;
generating a set of tenant-specific example phrases for each of the tenant-specific permitted actions based on metadata associated with the tenant-specific permitted actions, each example phrase representing a natural language request for performing a corresponding permitted action; and
configuring a tenant-specific chatbot to:
(i) receive a natural language request to perform one of the tenant-specific permitted actions,
(ii) for an example phrase from the sets of example phrases, input the natural language request and the example phrase into a neural network to receive a score indicating whether said example phrase can be inferred from the natural language request, wherein the neural network is configured to receive (a) an input natural language request and (b) an input example phrase and output a score indicating whether the input example phrase can be inferred from the input natural language request, and
(iii) if a score obtained from an example phrase meets a threshold indicating that the example phrase can be inferred from the natural language request, perform the tenant-specific permitted action corresponding to the example phrase.

storing a plurality of different sets of example phrases, wherein the set of example phrases is one of the plurality of different sets; and
using the trained neural network against each of the plurality of sets of example phrases without retraining the neural network for each distinct set of example phrases.
8. The method of claim 1 , wherein a particular natural language request maps to two different actions for two different tenants.
9. The method of claim 7 , wherein each tenant has a distinct set of entity types and actions, wherein each tenant stores a set of example phrases different from sets of example phrases of other tenants.
10. The method of claim 1 , wherein the tenant-specific chatbot is configured for a subset of users from an organization associated with a multi-tenant system.
11. A non-transitory computer readable storage medium storing instructions that when executed by one or more computer processors, cause the one or more computer processors to perform steps for enabling custom configuration of a tenant-specific chatbot to process and act upon natural language requests without requiring tenant-specific training, the steps comprising:
providing a user interface displaying a set of actions;
receiving a selection of one or more actions from the set of actions;
configuring the selected one or more actions as a tenant-specific set of permitted actions;
automatically generating a set of tenant-specific example phrases for each of the tenant-specific permitted actions based on metadata associated with the tenant-specific permitted actions, each example phrase representing a natural language request for performing a corresponding permitted action; and
configuring a tenant-specific chatbot to:
(i) receive a natural language request to perform one of the tenant-specific permitted actions,
(ii) for an example phrase from the set of example phrases, input the natural language request and the example phrase into a neural network to receive a score indicating whether said example phrase can be inferred from the natural language request, wherein the neural network is configured to receive (a) an input natural language request and (b) an input example phrase and output a score indicating whether the input example phrase can be inferred from the input natural language request, and
