The variations graph allows you to quickly understand how often a certain subject is mentioned in the DCF, your alerts or in your stored information. You will also be able to see how this subject is trending.
In this example, using flavours of tea, I can see that in the last week there have been 458 new mentions of "Iced Tea", and that compared to the previous week this is a 32% increase in mentions. "Breakfast tea" has only been mentioned 6 times, and this is down from the previous week.
When you conduct a search in the DCF, you will be able to see this type of analysis on the Visual Analysis page. Here is one using intitle:lego as the search term:
How to create a variations analysis
On a dashboard, click to add an analysis and then chose the "variations" graph. Inside the options you will see:
Entities: you can select to use a list of entities you have created yourself, or if you prefer you can use one of the Digimind Find Out lists.
Database: the choice is alerts, Digimind Content Factory or validated information
Query: you can combine the entities on your list with a query if you would like. For example I could choose to look for my tea flavors with other search terms to make my graph more precise.
Periodicity: select the length of time for which you would like the analysis to be conducted.
