Content analysis provides insight for better decision making in a wide range of business solution scenarios. 

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. 

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. 

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. 

Then, you can browse through the facets generated by the linguistic processor of Watson Content Analytics, and the facets defined by you. Watson Content Analytics helps you analyze contents with the following views: 

GLYPH<SM590000> Documents view. Shows a list of the actual content of individual documents and their metadata. By reading the original text, you can quickly verify that the text supports the analysis results. 

GLYPH<SM590000> Facets view. Shows a list of keywords of a selected facet. This view is useful for seeing the keywords that make up a given facet in your data. 

GLYPH<SM590000> Time Series view. Shows the frequency change over time. You can analyze the frequency of a selected facet over time, and refine documents by a selected date range. 

GLYPH<SM590000> Trends view. Shows sharp and unexpected increases in frequency over time. 

GLYPH<SM590000> Deviations view. Shows the deviation of keywords for a given time period. This view focuses on how much the frequency of a facet deviates from the expected average for a given time period, not from its past history as in the Trends view.
