At the beginning of content analysis, you need to gather data to be analyzed. For  example, if you want to understand how your customer perceives your products  or services, you need to gather data that contains your customers’ opinions. A review of the Part of Speech  facets  (or analysis axes) gives you an overview of  what subjects are involved, and of the major concepts in the data set. In addition  to the Part of Speech facets, you can define and create facets that become an  analysis axis. For example, you can define facets of created date, the customer  associated to the documents, location, and so on. After you gather the data, you can start analyzing the data. Watson Content  Analytics generates grammatical information about the textual data included in  documents, such as Noun, Verb, Adjective, Adverb and other parts of speech.  This information is useful for analysis of your data.  Then, you can browse through the facets generated by the linguistic processor of  Watson Content Analytics, and the facets defined by you.
