The account visit feedback given by account and product managers of a sales department is collected and saved into a database. Besides the basic structure created by the storage in a database, the feedback is free text which contains a lot of abbreviations and spoken language. The concepts of text mining are used to create an editorial tool with the goal to present the information to the analysts in a way that they are able to aggregate it to useful and meaningful phrases.
