Abstract

Aspects of the present invention provide a more universal, easy, natural, and vendor-agnostic interface to configure, manage, and/or monitor devices in networks. In embodiments, a user-friendly natural language interface, such as a chat or messaging interface, may be used to “live chat” with one or more devices. In embodiments, a natural language input from a user intended for a target device is received and converted into one or more properly formed commands that are target-specific for the target device and may be executed by the target device. In embodiments, results from the execution of the one or more commands may be appropriately formatted for presentation to the user.

Claims

1. A computer-implemented method for converting a natural language input into a command input for a target device comprising:

receiving a natural language input comprising free-form vocabulary, the natural language input being intended for a target device from among a plurality of potential target devices that requires commands to be properly formed for the target device to be executed;

performing natural language processing (NLP) input cleaning on the natural language input; and

performing input transformation on at least a portion of the cleaned natural language input to convert the cleaned natural language input into one or more properly formed commands that are target-specific for the target device by performing the steps comprising;

performing a lookup in a lemmatization database to convert at least some of the cleaned natural language input to a target-specific input that comprises target-specific vocabulary that corresponds to the target device; and

using the target-specific input to perform a lookup in a command template database to obtain a target-specific command template match corresponding to the target-specific input that comprises target-specific vocabulary, the target-specific command template being used to create at least one of the one or more properly formed commands.

2. The computer-implemented method of claim 1 wherein the step of performing natural language processing (NLP) input cleaning on the natural language input comprises performing one or more of the steps comprising:

responsive to the natural language input having plurals or reflexive pronouns, stemming the natural language input to remove any plurals and reflexive pronouns; and

responsive to the natural language input comprising compound statements, complex statements, or both, splitting the natural language input into two or more simple natural language inputs.

3. The computer-implemented method of claim 1 further comprises:

responsive to the target-specific command template match having one or more empty values, filling the one or more empty values from data obtained from the natural language input to obtain a properly formed target-specific command.

4. The computer-implemented method of claim 1 wherein the step of receiving a natural language input comprising free-form vocabulary comprises:

receiving the natural language input via a messaging application.

5. The computer-implemented method of claim 4 further comprising the step of:

presenting to a user via the messaging application one or more avatars corresponding to one or more target devices, which can be communicated with via the messaging application.

6. The computer-implemented method of claim 1 further comprising the step of:

submitting the one or more properly formed target-specific commands to the target device for execution.

7. The computer-implemented method of claim 6 further comprising:

receiving a set of results from the target device after execution of the one or more properly formed target-specific commands; and

formatting at least some of the results from the set of results for presentation to a user.

8. The computer-implemented method of claim 7 wherein the step of formatting at least some of the results from the set of results for presentation to a user comprises:

formatting at least of the results from the set of result for presentation to a user via a chat messaging application.

9. A natural language processing (NLP) system for converting a natural language input into a target-specific command input for a target device, the system comprising:

an end-point interface system comprising a natural language processing (NLP) interaction end-point server that receives a natural language input from a user, the natural language input being intended for a target device from among a plurality of potential target devices;

a transformation system that cleans the natural language input and transforms at least a portion of the cleaned natural language input into one or more properly formed commands that are target-specific for the target device, the transformation system comprising;

an NLP input cleaning and transformation logic module, which is communicatively coupled to the end-point interface system to receive the natural language input and is communicatively coupled to a lemmatization database, that performs a lookup in the lemmatization database to convert at least some of the natural language input into a target-specific input corresponding to the target device; and

a target-specific NLP processing engine module, which is communicatively coupled to the NLP input cleaning and transformation logic module and to a command template database, that performs a lookup in the command template database using the target-specific input to obtain a target-specific command template match for creating at least one of the one or more properly formed commands; and

a target-device interface module that communicates the one or more properly formed commands to the target device for execution by the target device.

10. The natural language processing (NLP) system of claim 9 wherein the target-specific NLP processing engine module is further configured to:

responsive to the target-specific command template match having one or more empty values, fill the one or more empty values from data obtained from the natural language input to obtain at least one of the one or more properly formed commands that are target-specific for the target device.

11. The natural language processing (NLP) system of claim 9 wherein the lemmatization database comprises:

a collection of structured records having a list of commands and each command is associated with list of terms related to different devices, different vendors, or both that are considered synonyms.

12. The natural language processing (NLP) system of claim 9 wherein the command template database comprises:

target-specific command templates, each target-specific command template being in a structured format and having an associated set of one or more tags related to usage of the target-specific command template; and

one or more indexes of the target-specific command templates.

13. The natural language processing (NLP) system of claim 9 further comprising:

an NLP response engine that is communicatively coupled to the target device interface module and that receives results data related to at least one of the one or more properly formed commands and forwards at least some of that data to a user.

14. The natural language processing (NLP) system of claim 13 wherein the NLP response engine is further configured to perform the step comprising:

formatting at least some of the results data for presentation to the user.

15. The natural language processing (NLP) system of claim 14 wherein the step of formatting at least some of the results data for presentation to the user comprises:

formatting the at least some of the results data for presentation to the user via a chat messaging application.

16. The natural language processing (NLP) system of claim 9 further comprising:

a training system that is communicatively coupled to the one or more sets of target-related documentation and that uses the target-related documentation to develop the lemmatization database and the command template database.

17. A computer-implemented method for generating one or more databases for use in converting a natural language input into a command input for a target device, the method comprising:

generating a lemmatization database that comprise a collection of structured records having a list of commands and each command is associated with list of terms related to different devices, different vendors, or both that are considered synonyms; and

generating a command template database comprises;

target-specific command templates, each target-specific command template being in a structured format and having an associated set of one or more tags related to usage of the target-specific command template; and
