Customer Care professionals capture customer feedback and comments during their interaction with various customers everyday. This comments data in the form of text is referred to as unstructured data. There has been an exponential growth in unstructured data, and analyzing this data is critical for forming business strategies.
You have access to this Comments data. You need to build a text mining system to mine this textual data and (eventually) categorize each comment as Positive or Negative so that the business can effectively track customer sentiment and make appropriate corrective strategies.
For example, the first comment mentioned below should be categorized as Positive, and second one as Negative: –
