The IT helpdesk of a large enterprise routinely conducts surveys of its users. The survey allows the users to rate the performance of the helpdesk and to enter about 3-4 lines of comments in a free form text field.
Which IBM Watson service should the IT helpdesk use to drive insights from the texts and to look for patterns among complains for improvements?
To analyze the text for patterns and sentiments in user comments, the best choice would be IBM Watson Discovery. This service can extract keywords and entities to identify common patterns in the comments and provide insights into the sentiment behind each comment. Personality Insights is used for analyzing personality traits and is not suitable for extracting patterns from text comments. Natural Language Classifier mainly classifies texts into predefined categories and is not specifically designed for extracting keywords or sentiment analysis.
A. Use Discovery to extract keywords and entities for common patterns across the comments plus gain insight into the sentiment expressed by each comment
