Use-case example: TF-IDF used for insurance feedback analysis
The feedback will then help to optimize and improve their service or web pages. The TF - IGF method, which stands for term frequency-inverse document frequency, is used for information retrieval and helps create so-called bags-of-words or the word corpus from the users' responses. The IDF technique penalizes stop words appearing in the text too many times. The TF method, in its turn, filters the unique valuable
words out, helping to define customers' claims and difficulties which they face, for example, using the online system. As a result, the business owner can react faster to customers' needs and claims, but also TF-IGF is not the panacea and cannot be implemented in any case.
