Abstract

Embodiments described herein are directed to computer-implemented methods, systems, and computer program products for calculating a metric using natural language processing tokens. A non-limiting example of the computer-implemented method includes parsing, by a processing device, user content using a natural language processing technique to extract tokens. The method further includes filtering, by the processing device, the tokens relating to a natural language processing criterion. The method further includes calculating, by the processing device, a metric based at least in part on the filtered tokens. The method further includes determining, by the processing device, whether to take an action by applying the metric to a set of rules. The method further includes taking the action responsive to determining to take the action.

First claim

What is claimed is:

1. A computer-implemented method comprising:
parsing, by a processing device, user content using a natural language processing technique to extract tokens;
filtering, by the processing device, the tokens relating to a natural language processing criterion relating to product safety for a product of interest;
determining, by the processing device, a severity for the user content, the severity being based on an incident associated with the product of interest, the incident being indicated in the user content;
simultaneously performing in parallel, by the processing device:
calculating a safety metric for the product of interest based at least in part on the filtered tokens and based at least in part on the severity; and
calculating a reputation factor for an author of the user content based at least in part on a determination of whether the author is a verified expert;

recalculating, by the processing device, the safety metric by multiplying the safety metric and the reputation factor for the author of the user content to generate an updated metric;
determining, by the processing device, whether to take an action by applying the updated metric to a set of rules; and
taking the action responsive to determining to take the action.

2. The computer-implemented method of claim 1 , wherein the user content relates to the product of interest.

3. The computer-implemented method of claim 2 , wherein the action comprises initiating a product recall for the product of interest.

4. The computer-implemented method of claim 2 , wherein the action comprises recommending a different product similar to the product of interest.

5. The computer-implemented method of claim 4 , wherein the safety metric is a first safety metric, wherein the first safety metric is associated with the product of interest, and wherein a second safety metric is associated with the different product.

6. The computer-implemented method of claim 5 , wherein the second safety metric is greater than the first safety metric.

7. The computer-implemented method of claim 1 , wherein the set of rules utilizes a plurality of thresholds to determine whether to take the action.

8. The computer-implemented method of claim 7 , wherein the plurality of thresholds comprises a first threshold that is less than a second threshold, wherein it is determined to take a first action when the safety metric is greater than the first threshold and less than the second threshold, and wherein it is determined to take a second action when the safety metric is greater than the first threshold and the second threshold.
